Abstract
The crystal structure of the tetra-ethyl-ammonium salt of the non-steroidal anti-inflammatory drug nimesulide (polymorph II) (systematic name: tetra-ethyl-ammonium N-methane-sulfonyl-4-nitro-2-phen-oxy-anilinide), C8H20N+·C13H11N2O5S-, was determined using single-crystal X-ray diffraction. The title compound crystallizes in the monoclinic space group P21/c with one tetra-ethyl-ammonium cation and one nimesulide anion in the asymmetric unit. In the crystal, the ions are linked by C-H⋯N and C-H⋯O hydrogen bonds and C-H⋯π inter-actions. There are differences in the geometry of both the nimesulide anion and the tetra-ethyl-ammonium cation in polymorphs I [Rybczyńska & Sikorski (2023 ▸). Sci. Rep. 13, 17268] and II of the title compound.

Abstract
BACKGROUND Toxic Epidermal Necrolysis (TEN) is a rare, acute, and life-threatening mucocutaneous disease that occurs after the administration of certain drugs, resulting in extensive keratinocyte cell death, skin involvement at the dermal-epidermal junction, and extensive bullous skin eruptions and sloughing. Many published case reports have observed the presence of fever with a viral infection, drug, and/or genetic association as a possible trigger for TEN but associated with other comorbidities. Physicians still struggle to predict which individuals could be predisposed to TEN. The case report that we present had a history of multiple drug intake and fever due to dengue virus infection but was not associated with any other comorbidity. CASE PRESENTATION We present an unusual case of a 32-year-old woman of Western Indian origin who had developed dengue infection and suffered toxic epidermal necrolysis following a five-day course of a third-generation cephalosporin antibiotic, cefixime and a three-day course of 2 analgesic drugs, paracetamol (acetaminophen), and nimesulide, with the adverse event occurring on the fifth day of the dengue infection. The offending drugs were stopped, and patient survived with supportive management and hydration. CONCLUSION The presence of comorbidities may not always be the triggering factor for TEN, though it can affect patient outcomes. Rational drug use is always recommended for patient care. Further research is required to understand the pathomechanism behind the viral-drug-gene interaction.

Abstract
The presence of a chiral or chirally perturbed chromophore in the molecule under investigation is a fundamental requirement for the appearance of a circular dichroism (CD) spectrum. For native and for most of the substituted cyclodextrins, this condition is not applicable, because although chiral, cyclodextrins lack a chromophore group and therefore have no characteristic CD spectra over 220 nm. The reason this method can be used is that if the guest molecule has a chromophore group and this is in the right proximity to the cyclodextrin, it becomes chirally perturbed. As a result, the complex will now provide a CD signal, and this phenomenon is called induced circular dichroism (ICD). The appearance of the ICD spectrum is clear evidence of the formation of the complex, and the spectral sign and intensity is a good predictor of the structure of the complex. By varying the concentration of cyclodextrin, the ICD signal changes, resulting in a saturation curve, and from these data, the stability constant can be calculated for a 1:1 complex. This article compares ICD and NMR spectroscopic and molecular modeling results of cyclodextrin complexes of four model compounds: nimesulide, fenbufen, fenoprofen, and bifonazole. The results obtained by the different methods show good agreement, and the structures estimated from the ICD spectra are supported by NMR data and molecular modeling.

Abstract
An alternative to oral administration for the delivery of therapeutic substances is the topical route, which frequently has comparable efficacy but may have a better tolerability profile. Gamma scintigraphy is a noninvasive technique that involves the application of radioactive substances to conduct biodistribution studies of therapeutic substances delivered through various routes. Nimesulide (NSD) was radiolabeled with technetium pertechnetate (Technetium99m [99mTc]) and this radiolabeled drug complex (99mTc-NSD) was used to prepare a topical gel formulation. The permeation of the radiolabeled drug from the topical gel was determined by gamma scintigraphy on human volunteers. The region of interest was calculated for the quantification of permeated radiolabeled drugs. This was observed that the mean percentage permeation of 99mTc-NSD was found to be 0.32 ± 0.22 to 36.37 ± 2.86 at 5 and 240 min. It was demonstrated that gamma scintigraphy may be a noninvasive and reliable technique for the determination of drug permeation through topical routes.

Abstract
Acute myeloid leukemia (AML) is a hematologic malignancy associated with high morbidity and mortality. Here we describe a case of a patient with AML who presented a partial response after utilization of the non-steroidal anti-inflammatory drug nimesulide. The response was characterized by complete clearance of peripheral blood blasts and an 82% decrease of bone marrow blasts associated with myeloblast differentiation. We have then shown that nimesulide induces in vitro cell death and cell cycle arrest in all AML cell lines (HL-60, THP-1, OCI-AML2, and OCI-AML3). Weighted Correlation Network Analysis (WGCNA) of serial whole-transcriptome data of cell lines treated with nimesulide revealed that the sets of genes upregulated after treatment with nimesulide were enriched for genes associated with autophagy and apoptosis, and on the other hand, the sets of downregulated genes were associated with cell cycle and RNA splicing. Serial transcriptome of bone marrow patient sample confirmed the upregulation of genes associated with autophagy after the response to nimesulide. Lastly, we demonstrated that nimesulide potentiates the cytotoxic in vitro effect of several Food and Drug Administration (FDA)-approved chemotherapy drugs used in AML, including cytarabine.

Abstract
Background and Aim This study aimed to evaluate acute postoperative pain management and trismus in 35 patients undergoing extractions of the two mandibular third molars, in mesioangular positions, at two different visits who consumed nimesulide + thiocolchicoside or only nimesulide. Material and Methods According to the medication given, the patients were divided into two groups. Following the first surgery of the impacted third molar patients were given nimesulide (100 mg) + thiocolchicoside (8 mg) together. The healing period was waited for 15 days and in the poursuite of the second surgery, only nimesulide (100 mg) was administered every 12 hours for 7 days. Visual analog scales (VAS) were used to assess the pain in the 6th, 8th, 12th, 24th, and 48th hours and on the 3rd, 5th, and 7th days postoperatively. Digital calipers were used to measure (in mm) the mouth opening capacity pre and postoperatively on the 2nd and 7th days, respectively. Results Regarding pain alleviation, the nimesulide + thiocolchicoside group was more effective than the nimesulide group. The VAS levels of nimesulide + thiocolchicoside at the 6th, 8th, 12th, 24th, and 48th hours and on the 3rd and 5th days were significantly lower than the nimesulide group. The mouth opening was observed higher in the nimesulide + thiocolchicoside group than in the nimesulide group (P > 0.05). In the nimesulide group, at the end of the 7th day, the trismus measurements were less than the preoperative measurements. There was no statistically significant difference in the Nimesulide + Thiocolchicoside group in the preop-7th days. Conclusion Nimesulide (100 mg) + thiocolchicoside (8 mg) combination has higher analgesic efficacy and better trismus outcomes compared to only nimesulide (100 mg) when orally administered following mandibular third molar surgeries.

Abstract
Oxidative stress and inflammation act on skin squamous cell carcinoma (SSCC) development and progression. Curative therapy for SSCC patients is mainly based on surgical resection, which can cause various sequelae. Silver ions have in vitro activities over tumor cells, while nimesulide has antioxidant and anti-inflammatory activities. This study aimed to evaluate the effects of a silver(I) complex with nimesulide (AgNMS) incorporated in a sustained release device based on bacterial cellulose membrane, named AgNMS@BCM, on topic SSCC treatment. The antiproliferative effect of AgNMS complex was evaluated in the SCC4, SCC15 and FaDu SCC lines. AgNMS complex activity on exposure of phosphatidylserine (PS) residues and multicaspase activation were evaluated on FaDu cells by flow cytometry. The AgNMS@BCM effects were evaluated in a SSCC model induced by 7,12-dimethylbenzanthracene/12-o-tetradecanoyl-phorbol-13-acetate (DMBA/TPA) in mice. Toxicity and tumor size were evaluated throughout the study. AgNMS complex showed antiproliferative activity in SCC15 and FaDu lines in low to moderate concentrations (67.3 µM and 107.3 µM, respectively), and induced multicaspase activation on FaDu cells. The AgNMS@BCM did not induce toxicity and reduced tumor size up to 100%. Thus, the application of AgNMS@BCM was effective and safe in SSCC treatment in mice, and can be seen as a potential and safe agent for topic treatment of SSCC in humans.

Abstract
Our previous studies identified that nimesulide analogs which bear a methoxy substituent at the para-position of the phenyl ring could be potential radiotracer candidates for detecting disorders related to cyclooxygenase-2 (COX-2) expression and activity in vivo using positron emission tomography (PET) in the brain. The present study was conducted to evaluate the in vivo characteristics of 11C-labeled para-methoxy nimesulide ([11C]1d) as a brain COX-2-targeted imaging agent compared to other isomeric methoxy analogs of nimesulide ([11C]1b and [11C]1c). [11C]1b-d were synthesized with reasonable yield and purity by the methylation of the O-desmethyl precursor with [11C]methyl triflate in the presence of NaOH at room temperature. We performed in vivo biodistribution analysis, brain PET imaging, ex vivo autoradiography, and metabolite analysis in mice. The uptake of [11C]1b-d was lower in the brain than in other tissues, including in the blood, and both [11C]1c and [11C]1d were rapidly metabolized. However, [11C]1d showed a small, but significant, specific signal and heterogeneous distribution in the brain. In vivo evaluation suggested that [11C]1d might correlate with COX-2 expression in the brain. Given its instability in vivo, [11C]1d seems unsuitable as a brain-COX-2 radioimaging agent. Further structural refinement of these radiotracers is necessary to enhance their uptake in the brain and to achieve sufficient metabolic stability.

Abstract
Nimesulide, salicylic acid and their binary mixtures were studied by differential scanning calorimetry (DSC) and Fourier Transform Infrared spectroscopy (FTIR). The study of such systems is a promising and viable approach for solving the problem of poor solubility of materials in general and drug systems in particular. All areas of human activity are inextricably linked to materials, and thus, the study presented in the paper and not reported in the literature is very important and provides useful data for those working in various fields. The eutectic mixtures were obtained by mechanosynthesis and by recrystallization from ethanol over the entire 0-1 range of molar fractions. For both situations at the molar fraction of nimesulide 0.5, the mixture has a eutectic that suggests an increase in solubility at this composition. The interactions that take place between the components were determined with the help of the excess thermodynamic functions (GE, SE, µE), which highlight the deviation from the ideality of the considered binary systems.

Abstract
Inhibiting the intestinal and renal neutral amino acid transporter B0AT1 by genetic means has improved insulin sensitivity in mice, but there are no antagonists available for preclinical or clinical use. Since the anti-inflammatory agent nimesulide selectively inhibited B0AT1 in vitro, we hypothesized that nimesulide exhibits in vivo potential to restrict neutral amino acid absorption and, therefore, may improve insulin sensitivity. The dose-related effect of nimesulide (10 to 100 mg/kg, PO) on intestinal absorption of neutral amino acids was estimated in C57 mice. The effect of nimesulide (50 mg/kg, PO) on renal resorption of amino acids was also assessed. The effect of chronic nimesulide (50 mg/kg, PO, BID for 14 days) was assessed in high protein diet-fed C57 mice, diet-induced obese mice and obese and diabetic db/db mice. Acute and chronic nimesulide treatment decreased absorption of neutral amino acids and increased their urinary excretion. Nimesulide treatment improved insulin sensitivity and glycemic control, increased GLP-1, decreased liver lipids and improved FGF-21 in serum. Nimesulide improved insulin sensitivity and glucose tolerance by inhibiting neutral amino acid transport in the intestine and kidneys. Thus, it can serve as a tool compound for in vivo B0AT1 inhibition.

Abstract
![]()
In this work, we
employed broad-band dielectric spectroscopy to
determine the solubility limits of nimesulide in the Kollidon VA64
matrix at ambient and elevated pressure conditions. Our studies confirmed
that the solubility of the drug in the polymer matrix decreases with
increasing pressure, and molecular dynamics controls the process of
recrystallization of the excess of amorphous nimesulide from the supersaturated
drug–polymer solution. More precisely, recrystallization initiated
at a certain structural relaxation time of the sample stops when a
molecular mobility different from the initial one is reached, regardless
of the temperature and pressure conditions. Finally, based on the
presented results, one can conclude that by transposing vertically
the results obtained at elevated pressures, one can obtain the solubility
limit values corresponding to low temperatures. This approach was
validated by the comparison of the experimentally determined points
with the theoretically obtained values based on the Flory–Huggins
theory.

Abstract
BACKGROUND Data on preemptive analgesia in periodontal surgeries are scarce and still diverse. The aim of this study was to evaluate and compare the analgesic effects of the preemptive administration of ibuprofen and nimesulide in open flap periodontal surgeries. METHODS The present randomized controlled clinical trial comprised 40 individuals, divided into two groups (n = 20), according to the test drug (ibuprofen and nimesulide) to be administered 1 hour preoperatively. Participants underwent bilateral periodontal surgeries at two different times, and were randomly given the test drug or placebo in a split-mouth design. Postoperative pain and rescue medication were evaluated at different times. Comparisons between ibuprofen and nimesulide were performed through a Generalized Estimation Equation model, using test drug and evaluation times, along with an interaction between these two variables as predictors. RESULTS In intergroup comparisons regarding pain control, ibuprofen showed better effects than placebo only at the first postoperative hour, whereas nimesulide showed better effects than placebo at 1, 6, 24, and 48 postoperative hours. In intergroup comparisons, nimesulide showed better effects than ibuprofen at 24, 48, and 72 postoperative hours, demonstrating a higher overall preemptive effect. No differences were observed in relation to the number of rescue medication. CONCLUSION Preemptive administration of nimesulide showed better overall preemptive effects on postoperative pain control when compared with ibuprofen.

Abstract
Nimesulide (NIM, N-(4-nitro-2-phenoxyphenyl)methanesulfonamide) is a relatively new nonsteroidal anti-inflammatory analgesic drug. It is practically insoluble in water (<0.02 mg/mL). This very poor aqueous solubility of the drug may lead to low bioavailability. The objective of the present study was to investigate the possibility of improving the solubility and the bioavailability of NIM via complexation with polysaccharide arabinogalactan (AG), disodium salt of glycyrrhizic acid (Na2GA), hydroxypropyl-β-cyclodextrin (HP-β-CD) and MgCO3. Solid dispersions (SD) have been prepared using a mechanochemical technique. The physical properties of nimesulide SD in solid state were characterized by differential scanning calorimetry and X-ray diffraction studies. The characteristics of the water solutions which form from the obtained solid dispersions were analyzed by reverse phase and gel permeation HPLC. It was shown that solubility increases for all complexes under investigation. These phenomena are obliged by complexation with auxiliary substances, which was shown by 1H-NMR relaxation methods. The parallel artificial membrane permeability assay (PAMPA) was used for predicting passive intestinal absorption. Results showed that mechanochemically obtained complexes with polysaccharide AG, Na2GA, and HP-β-CD enhanced permeation of NIM across an artificial membrane compared to that of the pure NIM. The complexes were examined for anti-inflammatory activity on a model of histamine edema. The substances were administered per os to CD-1 mice. As a result, it was found that all investigated complexes dose-dependently reduce the degree of inflammation. The best results were obtained for the complexes of NIM with Na2GA and HP-β-CD. In noted case the inflammation can be diminished up to 2-fold at equal doses of NIM.

Abstract
Pancreatic cancer is an aggressive, devastating disease due to its invasiveness, rapid progression, and resistance to surgical, pharmacological, chemotherapy, and radiotherapy treatments. The disease develops from PanINs lesions that progress through different stages. KRAS mutations are frequently observed in these lesions, accompanied by inactivation of PTEN, hyperactivation of the PI3K/AKT pathway, and chronic inflammation with overexpression of COX-2. Nimesulide is a selective COX-2 inhibitor that has shown anticancer effects in neoplastic pancreatic cells. This drug works by increasing the levels of PTEN expression and inhibiting proliferation and apoptosis. However, there is a need to improve nimesulide through its encapsulation by solid lipid nanoparticles to overcome problems related to the hepatotoxicity and bioavailability of the drug.

Abstract
Here, we present an excellent strategy of unmodified near-ultraviolet fluorescence nitrogen doping carbon nanobelts (NFNCBs) for detecting nimesulide (Nim). After a simple hydrothermal process of uric acid and hydroquinone in DMF solvent, NFNCBs shows the shape of corroded stalactite-like composed of nanobelts aggregates, near-ultraviolet luminescence and a narrowed full width at half maximum. This could improve/change the electronic properties and surface chemical active site, as the result of a sensitive response to Nim. By employing this sensor, the quantitative measurement displays a linear range of 2.0 nM - 100.0 μM with a lower detection limit of 0.21 nM (3σ/k) for Nim. Our work has provided a high selectivity for Nim, which may be capable for pharmaceutical sample analysis in real tablets. Furthermore, the results concerning the recoveries (96.3 - 106.2%) for real sample analysis indicate that this nanoprobe might expand a good avenue to design an effective luminescence nanoprobe for other biologically related drugs.

Abstract
An increasing number of drugs are metabolized by aldehyde oxidase (AOX), but AOX-mediated drug interactions are seldom reported due to the lack of appropriate inhibitors and inducers. A recent study reported that nimesulide (NIM) could increase the liver injury risk of methotrexate. The latter was mainly metabolized by AOX to form hepatotoxic 7-hydroxymethotrexate (7-OH MTX). Thus, we speculated that NIM could induce AOX. In this study, we investigated the potential induction of AOX activity by NIM using methotrexate as the probe substrate. Treatment of primary human and rat hepatocytes with NIM (20 μM) for 24 h caused a 2.0- and 3.1-fold, respectively, increase in 7-OH MTX formation. Oral administration of NIM (100 mg·kg−1·d−1, for 5 days) to rats significantly increased the systematic exposure (6.5-fold), liver distribution (2.5-fold), and excretion (5.2-fold for urinary excretion and 2.1-fold for fecal excretion) of 7-OH MTX. The 7-OH MTX formation in liver cytosol from rats pretreated with 20, 50, and 100 mg·kg−1·d−1 NIM for 5 days increased by 1.9-, 3.2-, and 3.7-fold, respectively, compared with that of rats pretreated with the vehicle. We revealed that the elevation of AOX activity was accompanied by an increase in AOX1 protein levels but not the corresponding mRNA levels. Collectively, our results demonstrate for the first time that NIM can increase the AOX activity of humans and rats, and may raise concerns regarding the risk of drug interactions between NIM and AOX substrates in clinical practice.

Abstract
The study was designed to investigate the effect of Nimesulide (NIM) on acute lung injury (ALI) in mice with severe acute pancreatitis (SAP). In our study, caerulein and LPS were employed to establish the ALI mice model induced by SAP. All animals were divided into four groups randomly: control, model (SAP), NIM low and high dosages groups. Following treatment with NIM, histopathology observation of pancreatic tissues and lung tissues were detected by hematoxylin and eosin (H&E) staining. The levels of serum amylase, lipase, tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β) and IL-6 were measured by ELISA. The ratio of wet lung to dry lung (W/D) was calculated. In addition, the expression levels of TNF-α, IL-1β and IL-6 were measured by Western blotting. Moreover, the expression of cyclooxygenase-2 (COX-2) was detected using Immunohistochemistry analysis. The results revealed that NIM markedly improved pancreatic histological injury and decreased the levels of serum amylase, lipase, TNF-α, IL-1β and IL-6 in a dose-dependent after NIM treatment. For ALI induced by SAP, pulmonary edema were significantly alleviated compared with the mice in SAP group. In addition, the decreased ratio of W/D were observed after NIM intervene. The expression levels of TNF-α, IL-1β and IL-6 proteins were downregulated following NIM treatment. More, NIM inhibited the expression of COX2 in lung tissues. Taken together, our study demonstrated that NIM was able to protect against ALI induced by SAP via inhibiting inflammation, which will be of novel therapeutic strategies for the clinical treatment of ALI.

Abstract
Squamous cell carcinoma (SCC) remains a main cause of mortality in patients with neck and head cancers, with poor prognosis and increased prevalence despite of available therapies. Recent studies have identified a role of cyclooxygenases, particularly inducible isoform cyclooxygenase-2 (COX-2) and its metabolite prostaglandin E2 (PGE2) in cancer cell proliferation, and its inhibition become a target for control of cancer development, particularly in the view of recognized additive or synergic action of COX-2 inhibitors with other forms of therapy. Nimesulide (N), the selective COX-2 inhibitor, inhibits growth and proliferation of various types of cancer cells by COX-2 dependent and independent mechanisms. In the presented study, the conjugates of biotinylated third generation poly(amidoamine) dendrimer (PAMAM) with covalently linked 18 (G3B18N) and 31 (G3B31N) nimesulide residues were synthesized and characterized by NMR spectroscopy. Biological properties of conjugates were evaluated, including cytotoxicity, proliferation, and caspase 3/7 activities in relation to COX-2/PGE2 axis signaling in human normal fibroblast (BJ) and squamous cell carcinoma (SCC-15). Both conjugates exerted a selective cytotoxicity against SCC-15 as compared with BJ cells at low 1.25-10 µM concentration range and their action in cancer cells was over 250-fold stronger than nimesulide alone. Conjugates overcome apoptosis resistance and sensitized SCC-15 cells to the apoptotic death independently of COX-2/PGE2 axis. In normal human fibroblasts the same concentrations of G3B31N conjugate were less effective in inhibition of proliferation and induction of apoptosis, as measured by caspase 3/7 activity in a manner depending on increase of PGE2 production by either COX-1/COX-2.

Abstract
Diphenyl ethers (DPE) and its analogs have exhibited excellent potential for therapeutic and industrial applications. Since the 19th century, intensive research is perpetuating on the synthetic routes and biological properties of DPEs. Few well-known DPEs are Nimesulide, Fenclofenac, Triclosan, Sorafenib, MK-4965, and MK-1439 which have shown the potential of this moiety as a lead scaffold for different pharmacological properties. In this review, we recapitulate the diverse synthetic route of DPE moiety inclusive of merits and demerits over the classical synthetic route and how this moiety sparked an interest in researchers to discern the SAR (Structure Activity Relationship) for the development of diversified biological properties of DPEs such as antimicrobial, antifungal, antiinflammatory & antiviral activities.

Abstract
A boy aged 6 years and 3 months developed upper respiratory tract infection and pyrexia 2 months ago and was given oral administration of nimesulide by his parents according to directions. Half an hour later, the boy experienced convulsions and cardiopulmonary arrest, and emergency examination found hypoketotic hypoglycemia, metabolic acidosis, significant increases in serum aminotransferases and creatine kinase, and renal damage. Recovery of consciousness and vital signs was achieved after cardiopulmonary resuscitation, but severe mental and movement regression was observed. The boy had a significant reduction in free carnitine in blood and significant increases in medium- and long-chain fatty acyl carnitine, urinary glutaric acid, 3-hydroxy glutaric acid, isovalerylglycine, and ethylmalonic acid, suggesting the possibility of multiple acyl-CoA dehydrogenase deficiency. After the treatment with vitamin B2, L-carnitine, and bezafibrate, the boy gradually improved, and reexamination after 3 months showed normal biochemical parameters. The boy had compound heterozygous mutations in the ETFDH gene, i.e., a known mutation, c.341G>A (p.R114H), from his mother and a novel mutation, c.1484C>G (p.P495R), from his father. Finally, he was diagnosed with multiple acyl-CoA dehydrogenase deficiency. Reye syndrome and sudden death symptoms were caused by nimesulide-induced acute metabolic crisis. It is concluded that inherited metabolic diseases may be main causes of Reye syndrome and sudden death, and biochemical and genetic analyses are the key to identifying underlying diseases.

Abstract
Purpose This study investigated the safety and efficacy of fixed-dose combination tablets of naproxen/esomeprazole magnesium and nimesulide/pantoprazole to determine if both regimens are equally suited to relieve pain in patients with osteoarticular diseases and dyspeptic symptoms. Methods Patients were randomly assigned to receive either nimesulide/pantoprazole (100 mg/20 mg) twice daily or naproxen/esomeprazole magnesium (500 mg/20 mg) twice daily for 14 days. The primary endpoint was defined as the mean change in modified Western Ontario and McMaster Universities Osteoarthritis Index pain subscale. Secondary endpoints were mean visual analog scale score of dyspeptic symptoms (nausea, abdominal discomfort/pain, epigastric burning, postprandial fullness), mean visual analog scale score of individual dyspeptic symptoms, and individual score of dyspeptic symptoms according to patient diary. This study is registered at ClinicalTrials.gov: NCT01670552. Results A total of 490 patients were enrolled and randomized, and 399 completed treatment (naproxen/esomeprazole, n=201; nimesulide/pantoprazole, n=198). The difference in mean change in the modified Western Ontario and McMaster Universities Osteoarthritis Index pain score after 7 days of treatment between the two treatment groups was 2.33 mm (95% CI, −1.22 to 5.89 mm). After 14 days of therapy, the difference was 0.45 mm (95% CI, −3.29 to 4.19 mm). The most common adverse events in the pooled group were abdominal discomfort, abdominal distention, dyspepsia, and nausea, but none of these was deemed to be clinically meaningful. Conclusion The present study demonstrated noninferiority of a 14-day regimen with a fixed-dose combination of nimesulide/pantoprazole compared to naproxen/esomeprazole for the treatment of osteoarticular pain.

Abstract
The present study was designed to elucidate the influence of the magnetic field on the spectroscopic characteristics of nimesulide and glucosamine sulfate preparations. The secondary objective of the study was to evaluate the clinical effectiveness of the combined application of magnetotherapy and transdermal forms containing a non-steroidal anti-inflammatory preparation and a chondroprotector with the use of magnetophoresis. For this purpose, we analyzed the samples exposed to the running magnetic field in an infrared spectrometer to elucidate the changes in the optical characteristics of the preparations of interest. The clinical effectiveness of the combined application of magnetophoresis was estimated in 83 patients presenting with knee osteoarthritis. The use of the infrared spectroscopic technique in the combination with the Fourier analysis made it possible to visualize the absence of coarse optical defects and structural changes in the test samples under the influence of the physical factors which provides the basis for their physiophoretic administration. The clinical studies conducted with the application of the combined physio-pharmacological treatment have demonstrated the feasibility and high effectiveness of this approach for the management of the patients presenting with articular pathology. The rehabilitative measures accelerated the earlier appearance of the pronounced analgesic effect and promoted the restoration of the joint function. Moreover, they reduced the drug load and improved the quality of life of the patients.

Abstract
Pancreatic cancer is the fourth leading cause of cancer-associated cases of mortality worldwide. Prostaglandin-endoperoxide synthase 2 (COX-2) is considered a therapeutic target for prevention of pancreatic cancer. Nimesulide, a selective COX-2 inhibitor, can induce cell apoptosis, resulting in an anti-cancer effect. However, the mechanism underlying this effect remains to be elucidated. The present study aimed to evaluate the effects of nimesulide on proliferation of PANC-1 cells using an MTT assay. Apoptosis was evaluated by DNA laddering and Annexin V-fluorescein isothiocyanate/propidium iodide-stained flow cytometry. Furthermore, western blot analysis was used to elucidate the mechanism underlying nimesulide treatment in PANC-1 cells. It was determined that proliferation of PANC-1 cells was inhibited by nimesulide in a dose-dependent manner. Nimesulide promoted apoptosis of PANC-1 cells. Western blot analysis demonstrated that nimesulide increased expression of cleaved caspase-3 and apoptosis regulator Bax (Bcl-2 associated protein X), and decreased the expression of pro-caspase-3 and apoptosis regulator Bcl-2 (B-cell lymphoma 2). Furthermore, nimesulide enhanced expression of phosphatase and tensin homolog (PTEN), and decreased the expression level of COX-2 and vascular endothelial growth factor. In summary, the results of the present study demonstrated that nimesulide could induce apoptosis and inhibit growth of PANC-1 cells by enhancing the expression of PTEN, which indicates the potential of nimesulide to prevent tumor angiogenesis.

Abstract
Background Despite significant advances in diagnosis and therapy, the rate of survival of patients with oral cancers still remains poor as an appropriate treatment has not been found yet, due to side effects of chemo/radiotherapy. Aim This study aimed to identify molecular mechanisms of cell death of oral cancer cells caused by treatment with a nonselective Cox-2 inhibitor in combination with a low-dose chemotherapeutic drug. Methods Squamous cell carcinoma (SCC) cells SCC9 and SCC25 were subjected to mono- and combination therapy with nimesulide and cisplatin. Fluorescence-activated cell sorting (FACS), immunohistochemistry, high-pressure liquid chromatography (HPLC), microarray gene chips, and isobaric tags for a relative and absolute quantitation (iTRAQ) system were used. Results Increased numbers of apoptotic and necrotic SCC9/SCC25 cells were detected after combined exposure. ATP levels and the energy charge of SCC9 cells were significantly decreased after both individual and combined treatment. We detected and quantified a responsible gene, keratin 6a, and 540 relevant proteins. In SCC25 cells, ATP levels significantly decreased only after combination therapy. After combined treatment of SCC9 cells, significant upregulation of Histon-H2A/H2B/H4 was found, with a local discovery false rate of 0.003 for Histon-H2A and 0.0027 for Histon-H2B, respectively. Conclusion Compared to the single-drug treatment, combined treatment of the oral cancer cells with nimesulide and cisplatin increases and induces necrosis and apoptosis through different pathways. A significant effect of the cytoplasmic increase was also observed in histones of cell lines SCC9 and SCC25 that were previously treated with combined nimesulide and cisplatin therapy.

Abstract
Carrier-mediated drug delivery systems are promising therapeutics for targeted delivery and improved efficacy and safety of potent cytotoxic drugs. Nimesulide is a multifactorial cyclooxygenase 2 nonsteroidal anti-inflammatory drug with analgesic, antipyretic and potent anticancer properties; however, the low solubility of nimesulide limits its applications. Drugs conjugated with hyaluronic acid (HA) are innovative carrier-mediated drug delivery systems characterized by CD44-mediated endocytosis of HA and intracellular drug release. In this study, hydrophobic nimesulide was conjugated to HA of two different molecular weights (360 kDa as HA with high molecular weight [HAH] and 43kDa as HA with low molecular weight [HAL]) to improve its tumor-targeting ability and hydrophilicity. Our results showed that hydrogenated nimesulide (N-[4-amino-2-phenoxyphenyl]methanesulfonamide) was successfully conjugated with both HA types by carbodiimide coupling and the degree of substitution of nimesulide was 1%, which was characterized by 1H nuclear magnetic resonance 400 MHz and total correlation spectroscopy. Both Alexa Fluor® 647 labeled HAH and HAL could selectively accumulate in CD44-overexpressing HT-29 colorectal tumor area in vivo, as observed by in vivo imaging system. In the in vitro cytotoxic test, HA-nimesulide conjugate displayed >46% cell killing ability at a nimesulide concentration of 400 µM in HT-29 cells, whereas exiguous cytotoxic effects were observed on HCT-15 cells, indicating that HA-nimesulide causes cell death in CD44-overexpressing HT-29 cells. Regarding in vivo antitumor study, both HAL-nimesulide and HAH-nimesulide caused rapid tumor shrinkage within 3 days and successfully inhibited tumor growth, which reached 82.3% and 76.4% at day 24 through apoptotic mechanism in HT-29 xenografted mice, without noticeable morphologic differences in the liver or kidney, respectively. These results indicated that HA-nimesulide with improved selectivity through HA/CD44 receptor interactions has the potential to enhance the therapeutic efficacy and safety of nimesulide for cancer treatment.

Abstract
Recent clinical and epidemiological researches have declared that non-steroidal anti-inflammatory agents may display as antineoplastic agents and indicate pro-apoptotic and antiproliferative effects on cancer cells. The major purpose of this research was to develop a novel poly(ethyleneglycol)-block-poly(ε-caprolactone) (PEG-b-PCL) nano-sized particles encapsulated with nimesulide (NMS), a selective COX-2 inhibitor, and to evaluate its anticancer activity against MCF-7 breast cancer cells. NMS-encapsulated PEG-b-PCL nanoparticles were fabricated using three different production techniques: (i) by emulsion-solvent evaporation using a high shear homogenizer, (ii) by emulsion-solvent evaporation using an ultrasonicator, and (iii) by nanoprecipitation. Nanoparticles were evaluated with respect to the entrapment efficiency, size characteristics, drug release rates, thermal behavior, cell viability assays, and apoptosis. The resulting nanoparticles were found to be spherical shapes with negative surface charges. The average diameter of all nanoparticles ranged between 148.5 and 307.2 nm. In vitro release profiles showed that all nanoparticles exhibited a biphasic release pattern. NMS-loaded PEG-b-PCL nanoparticles demonstrated significant anticancer activity against MCF-7 breast cancer cells in a dose-dependent manner, and the effects of nanoparticles on cell proliferation were significantly affected by the preparation techniques. The nanoparticles developed in this work displayed higher potential for the NMS delivery against breast cancer treatment for the future.

Abstract
The amorphous state is of particular interest in the pharmaceutical industry due to the higher solubility that amorphous active pharmaceutical ingredients show compared to their respective crystalline forms. Due to their thermodynamic instability, drugs in the amorphous state tend to recrystallize; in order to avoid crystallization, it has been a common strategy to add a second component to hinder the crystalline state and form a thermally stable co-amorphous system, that is to say, an amorphous binary system which retains its amorphous structure. The second component can be a small molecule excipient (such as a sugar or an aminoacid) or a second drug, with the advantage that a second active pharmaceutical ingredient could be used for complementary or combined therapeutic purposes. In most cases, the compositions studied are limited to 1:1, 2:1 and 1:2 molar ratios, leaving a gap of information about phase transitions and stability on the amorphous state in a wider range of compositions. In the present work, a study of novel co–amorphous formulations in which the selection of the active pharmaceutical ingredients was made according to the therapeutic effect is presented. Resistance against crystallization and behavior of glass transition temperature (Tg were studied through calorimetric measurements as a function of composition and shelf time. It was found that binary formulations with Tg temperatures higher than those of pure components presented long-term thermal stability. In addition, significant increments of Tg values, of as much as 15 ∘C, were detected as a result of glass relaxation at room temperature during storage time; this behavior of glass transition has not been previously reported for co-amorphous drugs. Based on these results, it can be concluded that monitoring behavior of Tg and relaxation processes during the first weeks of storage leads to a more objective evaluation of the thermomechanical stability of an amorphous formulation.

Abstract
In this article we study the effectiveness of three well-known polymers: inulin, Soluplus, and PVP in stabilizing the amorphous form of nimesulide (NMS) drug. The recrystallization tendency of pure drug as well as measured drug-polymer systems were examined at isothermal conditions by broadband dielectric spectroscopy (BDS) and at nonisothermal conditions by differential scanning calorimetry (DSC). Our investigation has shown that the crystallization half-life time of pure NMS at 328 K is equal to 33 min. We found that this time can be prolonged to 40 years after adding 20% w/w PVP to NMS. This polymer proved to be the best NMS stabilizer, while the worst stabilization effect was exhibited by inulin. Additionally, our DSC, BDS, and FTIR studies indicate that for suppression of NMS recrystallization in the NMS-PVP system, the two mechanisms are responsible: the polymeric steric hindrances and the antiplastization effect exerted by the excipient.

Abstract
Aim Drug‐induced liver injury is one of the most serious adverse drug reactions and the most frequent reason for restriction of indications or withdrawal of drugs. Some nonsteroidal anti‐inflammatory drugs (NSAIDs) were withdrawn from the market because of serious hepatotoxicity. We estimated the risk of acute and serious liver injury associated with the use of nimesulide and other NSAIDs, with a prevalence of use greater than or equal to 5%. Methods This is a multicentre case–control study carried out in nine Italian hospitals from October 2010 to January 2014. Cases were adults, with a diagnosis of acute liver injury. Controls presented acute clinical disorders not related to chronic conditions, not involving the liver. Adjusted odds ratio (ORs) with 95% confidence interval (CI) were calculated initially with a bivariate and then multivariate analysis. Results We included 179 cases matched to 1770 controls. Adjusted OR for acute serious liver injury associated with all NSAIDs was 1.69, 95% CI 1.21–2.37. Thirty cases were exposed to nimesulide (adjusted OR 2.10, 95% CI 1.28–3.47); the risk increased according to the length of exposure (OR > 30 days: 12.55, 95% CI 1.73–90.88) and to higher doses (OR 10.69, 95% CI 4.02–28.44). Risk of hepatotoxicity was increased also for ibuprofen, used both at recommended dosages (OR 1.92, 95% CI 1.13–3.26) and at higher doses (OR 3.73, 95% CI 1.11–12.46) and for ketoprofen ≥ 150 mg (OR 4.65, 95% CI 1.33–10.00). Conclusion Among all NSAIDs, nimesulide is associated with the higher risk, ibuprofen and high doses of ketoprofen are also associated with a modestly increased risk of hepatotoxicity.

Abstract
Nonsteroidal anti-inflammatory drugs (NSAIDs) have a strong analgesic and anti-inflammatory effects and are widely used in clinical practice. Patients with chronic disorders of the joints, in particular the spine, are main consumers of NSAIDs. However, risk factors for side-effects should be taken into consideration in the treatment with NSAIDs, especially in patients of old age. The careful control of treatment taking into account the risk of developing gastrointestinal and cardiovascular events is needed.

Abstract
CSUOH0901, a novel anticancer derivative of nimesulide, exhibits very promising anticancer activities in various cancer cell lines. In order to support further pharmacological and toxicological studies of this promising anticancer drug candidate, an LC-MS/MS method was developed and validated in accordance with the US Food and Drug Administration guidelines. The drug molecules were extracted from plasma samples by protein precipitation and then analyzed with LC-ESI-MS/MS. An excellent analyte separation was achieved using a phenomenex C18 column with a mobile phase of 90% methanol and 5 m m of ammonium formate. The validated linear dynamic range was between 0.5 and 100 ng/mL and the achieved correlation coefficient (r(2)) was >0.9996. The results of inter- and intra-day precision and accuracy were satisfactory, that is, <12% for accuracy and within ±5% for precision at a low and high quality control concentrations, respectively. In addition, the analyte and internal standard (JCC76) were found to be stable under the storage conditions at -20°C for about 2 months. Hence, the acquired results proved that the LC-ESI-MS/MS method developed is precise, accurate and selective for the quantification of CSUOH0901 in plasma, and can be used for pharmacokinetic studies.

Abstract
The objective of our study is to research biochemically and histopathologically the effect of nimesulide on oxidative damage inflicted by ischemia-reperfusion (I/R) on the rat renal tissue. Twenty-four albino Wistar type of male rats were used for the experiment. The animals were divided into groups as: renal ischemia-reperfusion control (RIR), nimesulide+renal ischemia-reperfusion of 50 mg/kg (NRIR-50), nimesulide+renal ischemia-reperfusion of 100 mg/kg (NRIR-100), and sham groups (SG). In NRIR-50 and NRIR-100 groups were given nimesulide, and RIR and SG groups were given distilled water, an hour after anesthesia. Groups, except for the SG group, 1-h-ischemia and then 6-h-reperfusion were performed. In the renal tissue of the RIR group in which the malondialdehyde (MDA), myeloperoxidase (MPO), and 8-hydroxyguanine (8-OHGua) levels were measured, the COX-1 and COX-2 activities were recorded. Nimesulide at 100 mg/kg doses reduced the oxidant parameters more significantly than 50 mg/kg doses; on the other hand, it raised the antioxidant parameters. It has been shown that 100 mg/kg doses of nimesulide prevented the renal I/R damage more significantly than a dose of 50 mg/kg, which shows that nimesulide, in clinics, could be used in the prevention of I/R damage.

Abstract
BACKGROUND Regulatory decision for withdrawal of a drug from market in European Union (EU) or other developed countries poses a challenge to authorities in developing countries specially when decision varies from different countries, such as for nimesulide. OBJECTIVES To compare and evaluate, benefit and risk data for regulatory action, of nimesulide in India and EU. METHODS Data on Nimesulide from EU available from Report on EMA website and Indian data from published literature (SCOPUS data base), WHO Vigibase and International Medicines Statistics (IMS) was compared. RESULTS Publications from India on Adverse drug reactions (ADRs) are case reports (10) and case series (14). Drug Utilization Research (DUR) studies (17) are mostly from tertiary centres. Data in the WHO Vigibase is meagre, data from IMS is not easily available and there is regional variation in prescriptions. Thus incidence of ADRs per sale, prescription or defined daily does (DDD) cannot be calculated, as has been done for EU. CONCLUSION Limited and varying data in post marketing studies on ADRs and drug utilization for nimesulide from India made regulatory decision difficult. India and other similar countries could contribute to post marketing data for local and global regulatory decisions by systematically planned studies and networking within country and across countries in region.

Abstract
Nimesulide (NIM) is an insoluble nonsteroidal anti-inflammatory drug (NSAID). Complexation of drug with methyl β-cyclodextrin was evaluated to improve solubility and dissolution rate of NIM. Complexation was achieved via a coevaporation technique to obtain different drug to polymer molar ratios (1:1, 1:2, and 1:3). The physicochemical characterization of the systems using powder X-ray diffraction and infrared spectroscopy was carried out to understand the influence of this technological process on the physical status of single components and complex systems and to detect possible interactions between drug and carrier. Moreover, quantitative solubility and in vitro dissolution studies of NIM alone and NIM inclusion complexes were studied in the dissolution media of phosphate buffer pH 5.5 and 7.4. The analysis provided existence of a molecular interaction between drug and carrier together in the complex state. The study showed that the inclusion systems enhanced of drug solubility, dissolution rate, and anti-inflammatory activity.

Abstract
In addition to its anti-inflammatory activity, Meriva®, a proprietary lecithin formulation of curcumin, has been anecdotally reported to decrease acute pain in patients with various chronic diseases. Given that curcumin can desensitize transient receptor potential A1, a nociceptor seemingly also mediating the analgesic effect of acetaminophen, as well as inhibiting and downregulating the expression of cyclo-oxygenase 2, the selective target of nimesulide, a nonsteroidal anti-inflammatory agent, we carried out a pilot comparative study of the acute pain-relieving properties of these three agents. At a dose of 2 g (corresponding to 400 mg of curcumin), Meriva showed clear analgesic activity, comparable with that of a standard dose (1 g) of acetaminophen, but lower than that of a therapeutic (100 mg) dose of nimesulide. The analgesic activity of lower (1.5 g) doses of Meriva was less satisfactory, and the onset of activity was longer than that of nimesulide for both doses. On the other hand, gastric tolerability was significantly better than that of nimesulide and comparable with that of acetaminophen. Taken together, our results show that the preclinical analgesic properties of curcumin have clinical relevance, at least at a dose of 2 g as the Meriva formulation. While this dose is significantly higher than that used to relieve chronic inflammatory conditions (1–1.2 g/day), its pain-relieving activity could benefit from the general downregulation of the inflammatory response induced by curcumin, considering that the transient receptor potential channel-mediated mechanisms of analgesia are magnified by attenuation of inflammation. In patients on treatment with Meriva, this would also translate into better control of acute pain, providing a rationale for the analgesic properties associated with this curcumin formulation.

Abstract
Celecoxib, diclofenac, ibuprofen, and nimesulide are nonsteroidal anti-inflammatory drugs (NSAIDs) very commonly used for the treatment of moderate to mild pain, together with paracetamol (acetaminophen), a very widely used analgesic with a lesser anti-inflammatory effect. In the study reported here, we tested the efficacy of celecoxib, diclofenac, and ibuprofen on preprotachykinin mRNA synthesis, substance P (SP) release, prostaglandin E2 (PGE2) release, and protein kinase C epsilon (PKCɛ) translocation in rat cultured sensory neurons from dorsal root ganglia (DRGs). The efficacy of these NSAIDs was compared with the efficacy of paracetamol and nimesulide in in vitro models of hyperalgesia (investigated previously). While nimesulide and paracetamol, as in previous experiments, decreased the percentage of cultured DRG neurons showing translocation of PKCɛ caused by 100 nM thrombin or 1 μM bradykinin in a dose-dependent manner, the other NSAIDs tested did not have a significant effect. The amount of SP released by peptidergic neurons and the expression level of preprotachykinin mRNA were assessed in basal conditions and after 70 minutes or 36 hours of stimulation with an inflammatory soup (IS) containing potassium chloride, thrombin, bradykinin, and endothelin-1. The release of SP at 70 minutes was inhibited only by nimesulide, while celecoxib and diclofenac were effective at 36 hours. The mRNA basal level of the SP precursor preprotachykinin expressed in DRG neurons was reduced only by nimesulide, while the increased levels expressed during treatment with the IS were significantly reduced by all drugs tested, with the exception of ibuprofen. All drugs were able to decrease basal and IS-stimulated PGE2 release. Our study demonstrates novel mechanisms of action of commonly used NSAIDS.

Abstract
A rapid, nondestructive Raman spectroscopic method was developed for quantitative estimation of paracetamol and nimesulide in their combined dosage form. A Raman univariate calibration model was developed by measuring the peak intensities of paracetamol and nimesulide at 853 cm(-1) and 1336 cm(-1), respectively. The developed method was successfully applied for in situ, concurrent estimation of paracetamol and nimesulide in their combined dosage and method was also validated according to International Conference on Harmonisation guidelines. Thus, the developed Raman spectroscopic method can be applied for simultaneous estimation of paracetamol and nimesulide in their combined dosage form as a process analytical technology tool by pharmaceutical industries for routine quality control.

Abstract
Background Neuropathic pain is a chronic pain due to disorder in the peripheral or central nervous system with different pathophysiological mechanisms. Current treatments are not effective. Analgesic drugs combined can reduce pain intensity and side effects. Here, we studied the analgesic effect of nimesulide, nefopam, and morphine with different mechanisms of action alone and in combination with other drugs in chronic constriction injury (CCI) model of neuropathic pain. Methods Male Wistar rats (n = 8) weighing 150-200 g were divided into 3 different groups: 1- Saline-treated CCI group, 2- Saline-treated sham group, and 3- Drug-treated CCI groups. Nimesulide (1.25, 2.5, and 5 mg/kg), nefopam (10, 20, and 30 mg/kg), and morphine (1, 3, and 5 mg/kg) were injected 30 minutes before surgery and continued daily to day 14 post-ligation. In the combination strategy, a nonanalgesic dose of drugs was used in combination such as nefopam + morphine, nefopam + nimesulide, and nimesulide + morphine. Von Frey filaments for mechanical allodynia and acetone test for cold allodynia were, respectively, used as pain behavioral tests. Experiments were performed on day 0 (before surgery) and days 1, 3, 5, 7, 10, and 14 post injury. Results Nefopam (30 mg/kg) and nimesulide (5 mg/kg) blocked mechanical and thermal allodynia; the analgesic effects of morphine (5 mg/kg) lasted for 7 days. Allodynia was completely inhibited in combination with nonanalgesic doses of nefopam (10 mg/kg), nimesulide (1.25 mg/kg), and morphine (3 mg/kg). Conclusions It seems that analgesic drugs used in combination, could effectively reduce pain behavior with reduced adverse effects.

Abstract
Objectives: To compare the analgesic activity of nimesulide and paracetamol alone and their combination in animal models for the degree of analgesia and the time course of action. Materials and Methods: Analgesia was studied in albino rats using formalin test and in albino mice using writhing test and the radiant heat method. For each test, four groups of six animals each were orally fed with a single dose of nimesulide, paracetamol, and combination of nimesulide + paracetamol and gum acacia as control, respectively. Results: In all the three test models, all three drug treatments showed significant analgesia (P < 0.001) as compared to control, but there was no significant difference in the analgesia produced by either drugs alone or in combination. The radiant heat method demonstrated a quicker onset and longer duration of action with nimesulide, whereas writhing test showed a quicker onset of action with paracetamol. In formalin test, greater degree of analgesia was seen with individual drugs than that of the combination, though this difference was not statistically significant. Conclusions: Nimesulide and paracetamol combination offers no advantage over nimesulide alone or paracetamol alone, either in terms of degree of analgesia or onset of action. Therefore, our study supports the reports claiming irrationality of the fixed dose combination of nimesulide and paracetamol.

Abstract
Cyclooxygenase-2 (COX-2) inhibitor nimesulide derivatives compounds A and B decreased aromatase activity in breast cancer cells via a novel mechanism different to aromatase inhibitors (AIs), and were defined as "aromatase suppressors". Breast carcinoma cells (MCF-7aro and T47Daro) transfected with aromatase full gene were used to explore the mechanisms of the two compounds. They dose and time-dependently suppressed aromatase activity in MCF-7aro and T47Daro cells in the nanomole range. However, they neither directly inhibited aromatase, nor improved aromatase degradation even at much higher concentrations. They could also suppress androgen stimulated cell growth, but did not affect estrogen enhanced cell proliferation. These results suggest that compounds A and B selectively interfere with aromatase in breast cancer cells, but not estrogen receptor (ER) downstream to disrupt androgen mediated cell growth. Interestingly, compound B effectively inhibited LTED (long-term estrogen deprived MCF-7aro cell) cell growth, which is a model for AIs resistance, with an IC(50) of 4.68 ± 0.54 μM. The results indicate that compound B could potentially overcome AI resistance in breast cancer cell and could be used as a lead to design more potent derivatives.

Abstract
OBJECTIVE Cyclooxygenase isoenzyme is known to be expressed in different regions of brain, and is mainly used for the treatment of pain and inflammation. Recently, it is proposed that cyclooxygenase isoenzyme may also play a key role in the pathophysiology of various brain-related disorders. The present study was aimed to explore the protective effect of cyclooxygenase inhibitors on stress by using an animal model of chronic stress. METHODS The animals were forced to swim individually for a period of 6 min every day for 15 d. Then, the behavior (locomotor activity, anxiety and memory) and biochemical (lipid peroxidation, nitrite level, reduced glutathione, and catalase) alterations were assessed. RESULTS Forced swimming for 15 d caused impaired locomotor activity, anxiety-like behavior and decreased percentage of memory retention, as compared to naive mice (without chronic fatigue treatment). Biochemical analysis revealed significant increases in lipid peroxidation and nitrite level, while levels of reduced glutathione and catalase activity were both decreased. Chronic treatment with naproxen (14 mg/kg, i.p.), rofecoxib (5 mg/kg, i.p.), meloxicam (5 mg/kg, i.p.), nimesulide (5 mg/kg, i.p.) and valdecoxib (10 mg/kg, i.p.) significantly attenuated these behavioral and biochemical (oxidative damage) alterations in chronic-stressed mice. CONCLUSION The cyclooxygenase inhibitors could be used in the management of chronic fatigue-like conditions.

Abstract
The present study was undertaken to investigate the effect of dietary
supplementation with nimesulide or eugenol on N-nitrosodiethylamine
(DEN)-initiated early hepatocarcinogenesis in F344 male rats. Both compounds did
not alter the expression of cytochrome P450 (CYP) 2E1, the enzyme that plays a
major role in the activation of DEN to genotoxic products; however, nimesulide
induced the expression of CYP1A1. Western blot analysis revealed that COX-1 and
COX-2 protein expressions were not modulated by DEN compared with normal
controls. Furthermore, post-initiation feeding with nimesulide or eugenol did
not modulate COX-2 protein expression in normal or DEN-treated rats, whereas
eugenol significantly increased the liver prostaglandin E2
(PGE2) levels of DEN-injected animals compared with the DEN
controls. Ultimately, nimesulide or eugenol did not modify DEN-induced
hepatocarcinogenesis as evidenced by insignificant changes in the number and
size of preneoplastic placental glutathione S-transferase (GST-P) positive liver
foci compared with the DEN controls. These results suggest that COX-2, as well
as prostaglandin E2, may play no role in the post-initiation
development of DEN-induced rat hepatocarcinogenesis at an early stage.

Abstract
Studies were performed to investigate the effect of curing on the diffusion coefficients of water, as measured via the sorption technique, in acrylate polymeric films. The mathematical model selected for obtaining diffusion constants from the vapor-phase sorption studies was derived from the long-time Fourier equation used for diffusion into a planar sheet. For Eudragit NE films, the diffusion coefficients of water decreased continuously until a constant minimum value was reached. Diffusion coefficients in Eudragit RS films decreased initially but increased beyond 4 hours of curing at 70 degrees C and 90 degrees C. This latter result suggested the possible evaporation of plasticizer, which also results in a more dramatic increase in glass transition temperature with curing for the Eudragit RS free film in comparison to the Eudragit NE free film. Such loss of plasticizer could also lead to the formation of molecular-scale channels within the films, which would result in increased film permeability. To verify this proposed explanation, the amounts of triethyl citrate plasticizer in Eudragit RS free films were determined using Fourier-transform infrared spectrophotometry. An optimal curing condition was predicted for Eudragit NE and Eudragit RS films based upon the curing conditions at which a minimum value of the diffusion coefficient was reached.

Abstract
BACKGROUND Nimesulide is a nonsteroidal, anti-inflammatory drug that hasbeen used for a wide range of acute and chronic pain. A once-daily formulation of nimesulide is now commercially available, but its effectiveness in pain management after dental surgery has not been assessed. OBJECTIVE The aim of this study was to assess the analgesic effectiveness and tolerability of oral treatment with once-daily nimesulide versus ibuprofen q6h over 24 hours in patients with postoperative pain associated with surgical extraction of an impacted third molar. METHODS This 24-hour, double-blind, randomized, double-dummy, parallel-groupstudy was conducted at a private practice in Caracas, Venezuela. Patients aged between 12 and 60 years with moderate to severe pain after extraction of an impacted third molar were enrolled. Patients were randomized to receive a single dose of nimesulide (300-mg tablet) or ibuprofen (400-mg tablets) q6h for 24 hours. For double-dummy design, patients in the nimesulide group also received ibuprofen placebo tablets, to be taken q6h for 24 hours, and patients in the ibuprofen group received a nimesulide placebo tablet. The primary end points were pain intensity (PI) and pain relief scores over 24 hours. Secondary end points included total pain relief, PI difference (PID), sum of PID (SPID), time to first measurable change in PI (ie, PID ≥ 10 mm), and use of rescue medication (acetaminophen). Patients also rated the treatment's effectiveness as very poor to very good on questioning by the study investigator. Spontaneously reported adverse effects (AEs) were recorded. RESULTS Eighty-six patients were enrolled (56 females, 30 males), with 43 patientsper treatment group (mean age: nimesulide group, 25.2 years; ibuprofen group, 24.2 years). The baseline characteristics were statistically similar between the 2 groups. Compared with baseline, mean PI scores were significantly lower in both treatment groups at all time points throughout the study (P < 0.001). Mean PI scores were significantly lower in the nimesulide group compared with the ibuprofen group at 15 and 45 minutes and 1 hour after study drug administration (P ≤ 0.049). Time to first measurable change in PI was within the first 15 minutes in 22 patients (52%) in the nimesulide group and in 14 patients (33%) in the ibuprofen group (P = 0.03). Analgesia lasted 24 hours with nimesulide and ibuprofen (PI scores at 24 hours, 9.4 and 3.6, respectively). The mean PR score was significantly lower in the nimesulide group compared with the ibuprofen group at 1 hour after study drug administration (P = 0.049). Compared with baseline, PID and SPID were significantly higher in both treatment groups throughout the study (P < 0.001). Significantly more patients in the nimesulide group than in the ibuprofen group reported that treatment provided effective pain relief (82% vs 73%; P = 0.013). No AEs were reported in either treatment group throughout the study. Use of rescue medication was statistically similar between the nimesulide and ibuprofen groups (38% and 31%, respectively). CONCLUSIONS In this study of patients with moderate to severe pain afterextraction of impacted third molars, nimesulide and ibuprofen provided effective 24-hour relief. However, the results suggest that the analgesic effect of nimesulide had a faster onset (<15 minutes) and was stronger (based on patient opinion) than that of ibuprofen. Both study drugs were well tolerated.

Abstract
BACKGROUND The cyclooxygenase-2 inhibitor nimesulide is able to reduce kainate-induced oxidative stress in vivo. Here we investigate if this effect is mediated by the direct antioxidant properties of nimesulide using a well-characterized in vitro model of kainate toxicity. RESULTS Exposure of rat brain homogenates to kainate (12 mM) caused a significant (p < 0.01) increase in the concentrations of malondialdehyde and 4-hydroxy-alkenals and a significant (p < 0.01) decrease in sulfhydryl levels. High concentrations of nimesulide (0.6-1.6 mM) reduced the extent of lipid peroxidation and the decline in both total and non-protein sulfhydryl levels induced by kainate in a concentration-dependent manner. CONCLUSIONS Our results suggest that the neuroprotective effects of nimesulide against kainate-induced oxidative stress in vivo are not mediated through its direct free radical scavenging ability because the concentrations at which nimesulide is able to reduce in vitro kainate excitotoxicity are excessively higher than those attained in plasma after therapeutic doses.

Abstract
The objective of this work is physicochemical characterization of nimesulide-cyclodextrin binary systems both in solution and solid state and to improve the dissolution properties of nimesulide (N) via complexation with alpha-, beta, and gamma-cyclodextrins (CDs). Detection of inclusion complexation was done in solution by means of phase solubility analysis, mass spectrometry, and 1H nuclear magnetic resonance (1H-NMR) spectroscopic studies, and in solid state using differential scanning calorimetry (DSC), powder x-ray diffractometry (X-RD), scanning electron microscopy (SEM), and in vitro dissolution studies. Phase solubility, mass spectrometry and 1H-NMR studies in solution revealed 1:1 M complexation of N with all CDs. A true inclusion of N with beta-CD at 1:2 M in solid state was confirmed by DSC, powder X-RD and SEM studies. Dissolution properties of N-CD binary systems were superior when compared to pure N.

Abstract
1. We investigated the effects of nimesulide, a recently developed non-steroidal anti-inflammatory drug, and of a metabolite resulting from reduction of the nitro group to an amine derivative, on succinate-energized isolated rat liver mitochondria incubated in the absence or presence of 20 microM Ca(2+), 1 microM cyclosporin A (CsA) or 5 microM ruthenium red. 2. Nimesulide uncoupled mitochondria through a protonophoretic mechanism and oxidized mitochondrial NAD(P)H, both effects presenting an EC(50) of approximately 5 microM. 3. Within the same concentration range nimesulide induced mitochondrial Ca(2+) efflux in a partly ruthenium red-sensitive manner, and induced mitochondrial permeability transition (MPT) when ruthenium red was added after Ca(2+) uptake by mitochondria. Nimesulide induced MPT even in de-energized mitochondria incubated with 0.5 mM Ca(2+). 4. Both Ca(2+) efflux and MPT were prevented to a similar extent by CsA, Mg(2+), ADP, ATP and butylhydroxytoluene, whereas dithiothreitol and N-ethylmaleimide, which markedly prevented MPT, had only a partial or no effect on Ca(2+) efflux, respectively. 5. The reduction of the nitro group of nimesulide to an amine derivative completely suppressed the above mitochondrial responses, indicating that the nitro group determines both the protonophoretic and NAD(P)H oxidant properties of the drug. 6. The nimesulide reduction product demonstrated a partial protective effect against accumulation of reactive oxygen species derived from mitochondria under conditions of oxidative stress like those resulting from the presence of t-butyl hydroperoxide. 7. The main conclusion is that nimesulide, on account of its nitro group, acts as a potent protonophoretic uncoupler and NAD(P)H oxidant on isolated rat liver mitochondria, inducing Ca(2+) efflux or MPT within a concentration range which can be reached in vivo, thus presenting the potential ability to interfere with the energy and Ca(2+) homeostasis in the liver cell.
