Abstract
Stevens-Johnson syndrome is a severe adverse drug reaction affecting the skin and mucous membrane. The causes include Sulfonamides, Anticonvulsants, etc. A patient developed ulcerations in the lips and oral cavity with difficulty in swallowing and rashes over the back, abdomen, and genitalia following administration of injection ceftriaxone 1 g intravenous (IV) b.i.d, injection pantoprazole 40 mg IV b.i.d, tablet aceclofenac + paracetamol 325 mg b.i.d, tablet cetirizine 10 mg b.i.d, chlorhexidine mouth wash, and injection metronidazole 500 mg IV t.i.d for the treatment of traumatic facial injury after 4 days of treatment. Injection ceftriaxone and tablet aceclofenac + paracetamol were suspected as the cause of this reaction. The two drugs were stopped. The patient was treated with corticosteroids, other antimicrobials, and oral topical anesthetics. Health-care providers should be careful about the possible adverse drug reactions even to commonly used drugs.

Abstract
The aim was to investigate eutectic transition during tableting and storage. Mixtures of lidocaine and series of NSAIDs with increasing melting point were used as model systems to guide formulators to scaleup eutectic forming materials gaining enhanced dissolution while avoiding deleterious physical changes. Physical mixtures of NSAIDs with lidocaine were prepared at eutectic forming ratio. These were directly compressed, dry co-ground before compression, or compressed after wet granulation. Dissolution of tablets was compared to corresponding dry co-ground mixture. Thermograms of direct compressed tablet were compared to co-ground mixture and pure compound. Stability of direct compressed tablets was assessed. Tableting initiated eutexia which enhanced dissolution of NSAIDs. Eutexia was associated with tablet softening in case of low melting point ketoprofen and aceclofenac. Wet granulation hastened eutexia developing unacceptable tablet in case ketoprofen and aceclofenac. Tablets prepared by direct compression of physical mixtures underwent gradual eutectic transition upon storage with the magnitude of eutectic transition reducing with increased melting point of NSAIDs. Ketoprofen was physically unstable but aceclofenac degraded chemically as well. Tenoxicam and meloxicam tablets were physically and chemically stable. Direct compression after physical mixing is the best tableting technique, but low melting point drugs should consider different strategy before compression.

Abstract
Aceclofenac (ACF) is a widely used non-steroidal anti-inflammatory drug (NSAID) known for its effectiveness in treating pain and inflammation. Recent studies have demonstrated that ACF possesses antiproliferative properties, inhibiting the growth of cancer cells in various cancer cell lines. Citronellol, a monoterpenoid alcohol found in essential oils, exhibits antioxidant properties and activities such as inhibiting cell growth and acetylcholinesterase inhibition. In this study, the objective was to formulate and evaluate an aceclofenac/citronellol oil nanoemulsion for its antiproliferative effects on melanoma. The optimal concentrations of citronellol oil, Tween 80, and Transcutol HP were determined using a pseudoternary phase diagram. The formulated nanoemulsions were characterized for droplet size, zeta potential, thermophysical stability, and in vitro release. The selected formula (F1) consisted of citronellol oil (1 gm%), Tween 80 (4 gm%), and Transcutol HP (1 gm%). F1 exhibited a spherical appearance with high drug content, small droplet size, and acceptable negative zeta potential. The amorphous state of the drug in the nanoemulsion was confirmed by Differential Scanning Calorimetry, while FTIR analysis indicated its homogenous solubility. The nanoemulsion showed significant antiproliferative activity, with a lower IC50 value compared to aceclofenac or citronellol alone. Flow cytometric analysis revealed cell cycle arrest and increased apoptosis induced by the nanoemulsion. In silico studies provided insights into the molecular mechanism underlying the observed antitumor activity. In conclusion, the developed aceclofenac/citronellol oil nanoemulsion exhibited potent cytotoxicity and pro-apoptotic effects, suggesting its potential as a repurposed antiproliferative agent for melanoma treatment. In a future plan, further animal model research for validation is suggested.

Abstract
Aceclofenac-loaded polyvinylpyrrolidone fiber-based amorphous solid dispersion was produced successfully by centrifugal spinning. The solution concentration and rotational speed were optimized to produce the fiber-based drug carrier system, with a determined production rate of 12.7 g/h dry solid fibers. The obtained fibers were bead-free and smooth-surfaced with an average diameter of 7.5 ± 2.5 μm. Gas chromatographic determinations revealed that ethanol, as a residual solvent, was well below the regulatory limit of 0.5%. Differential scanning calorimetric investigation and infrared spectroscopic measurements were used to track the physicochemical changes that intervene during fiber formation in the solid state. The results revealed that the rapid evaporation of the solvent was accompanied by a probable crystalline to amorphous transition of the active substance during centrifugal spinning. In vitro dissolution studies revealed an instantaneous disintegration of the fibrous structure and a rapid release of the active substance, with the microfibrous webs greatly outperforming the crystalline active substance, especially in the early time-points. This implies that centrifugal spinning offers a viable scale-up production process to prepare drug-loaded fiber-based solid dispersions.

Abstract
Rheumatoid arthritis (RA) is an inflammatory, autoimmune and connective-tissue arthropathy. The methotrexate (MTX) and aceclofenac (ACL) combination drug regimen is known to regulate the immunological pathways. Also, RA-elicited inflammation is decreased by the combination drug treatment. ACL and MTX combination treatment has been shown to regulate the signaling pathway controlled by NF-κB and FOXO1. The present manuscript reviews the importance of the combination drug regimen to treat and/or manage RA. The combination drug regimen could affect the Th1/Th17 axis to switch the balance toward the immunoregulatory (Th1) phenotype for establishing immune homeostasis. In conclusion, we propose the study of the immunological signaling pathways in experimental humanized RA mice.

Abstract
Aceclofenac (ACL) is an anti-inflammatory drug, which is taken by patients who mainly suffer from rheumatoid conditions. In this work, we propose a new voltammetric method that allows the determination of ACL in pharmaceutics, urine, and plasma. As a working electrode, a glassy carbon electrode (GCE) modified with carbon nanofibers, carbon nanotubes, and NiCo nanoparticles (eCNF/CNT/NiCo-GCE) was used. The mentioned sensors are characterized by good repeatability and sensitivity, and their process of preparation is simple, fast, and cost-effective. Instrumental and method parameters were optimized, and the influence of interferences was investigated. To validate the analytical performance of the method, calibration was conducted. Good linearity was obtained (0.05-1.4 µM, r = 0.998), as well as excellent limit of detection (LOD) and limit of quantification (LOQ) values (0.7 nM and 2.1 nM, respectively). Calculated recoveries that were in the range of 98%-105% indicate that this method is accurate and might be used in routine laboratory practice.

Abstract
PURPOSE Tegoprazan is a potassium-competitive acid blocker used for gastric acid suppression and may be used with NSAIDs to reduce gastrointestinal adverse effects. The aim of this study was to evaluate the pharmacokinetic interaction between tegoprazan and commonly used NSAIDS, namely, naproxen, aceclofenac, and celecoxib. METHODS An open-label, 3-cohort, randomized, multiple-dose, 3-way crossover study was conducted in healthy male subjects. In cohort 1, tegoprazan (50-mg tablet, once daily) and naproxen (500-mg tablet, twice daily) were administered separately or concurrently for 7 days in each period. In cohort 2, tegoprazan and aceclofenac (100-mg tablet, twice daily) were administered separately or concurrently for 7 days in each period. In cohort 3, tegoprazan and celecoxib (200-mg capsule, twice daily) were administered separately or concurrently for 7 days in each period. Pharmacokinetic blood samples were collected up to 24 hours after the last dose. FINDINGS Seventeen subjects from cohort 1, sixteen subjects from cohort 2, and thirteen subjects from cohort 3 were included in the pharmacokinetic analysis. In cohort 1, the geometric least squares mean ratios (90% CIs) for AUCτ (AUC profiles over the dosing interval) and Css,max (Cmax at steady state) were 1.01 (0.91-1.12) and 0.99 (0.83-1.17) for tegoprazan, and 1.00 (0.97-1.03) and 1.04 (0.99-1.09) for naproxen, respectively. The values in cohort 2 were 1.03 (0.93-1.13) and 0.94 (0.86-1.04) for tegoprazan, and 1.06 (1.00-1.12) and 1.31 (1.08-1.60) for aceclofenac. The values in cohort 3 were 1.01 (0.86-1.18) and 1.02 (0.87-1.19) for tegoprazan, and 1.08 (0.96-1.22) and 1.18 (0.97-1.43) for celecoxib. IMPLICATIONS Changes in the maximum aceclofenac or celecoxib concentrations were detected after concurrent administration with tegoprazan, which were considered mainly due to the pharmacodynamic effect of tegoprazan. Because systemic drug exposure (shown as AUCτ) was unchanged after concurrent administration of any 3 NSAIDs with tegoprazan, the increase in aceclofenac or celecoxib Css,max when administered with tegoprazan would not be clinically significant in practice.

Abstract
ABSTRACT OBJECTIVE To estimate the frequency of long-COVID in patients with chronic cerebrovascular disease, to identify the risk factors for the development of this condition and to analyze effectiveness and tolerability of Vinpocetine and Aertal in treatment of this disease. MATERIAL AND METHODS The study included 97 patients (64.5±5.2 years), among which 42 were diagnosed with long-COVID. The effectiveness of treatment was analyzed with NRS-P, Post-COVID-19 Functional Status (PCFS), Global Rating of Change Scale (GROC). RESULTS Predictors of long-COVID was female gender (p=0.022), severe COVID-19 (p=0.035), comorbidities: cardiovascular diseases (p=0.032), endocrinopathies (p=0.041), affective disorders (p=0.021). Significant changes in the functional status of patients were recorded after 20 days of treatment (PCFS), in pain after 10 days (NRS-P). The most pronounced clinical effect (PCFS) was obtained after 1 mth of therapy with vinpocetine and 20 days with aceclofenac (NRS-P). After 30 days 25/59.5% of patients noted a «pronounced» improvement in their own well-being (GROC) without the development of significant side effects. CONCLUSIONS 43.3% of patients with chronic cerebrovascular disease and certain predictors develop long-COVID. Aceclofenac and vinpocetine are effective in relieving a number of symptoms of long-COVID, which requires further study.

Abstract
Aceclofenac is an oral non-steroidal anti-inflammatory drug (NSAID) with anti-inflammatory and analgesic properties. Although there are some differences in the authorized indications between countries, aceclofenac is mainly recommended for the treatment of inflammatory and painful processes, such as low back pain (LBP), scapulohumeral periarthritis, extraarticular rheumatism, odontalgia, and osteoarthritis (OA), rheumatoid arthritis (RA), and ankylosing spondylitis (AS). The analgesic properties and tolerability profile of aceclofenac in musculoskeletal disorders are reviewed, focusing on relevant and recent studies. The efficacy and safety comparison of aceclofenac with other analgesics and anti-inflammatory agents in OA, AS, RA, and LBP is described. Relevant studies were identified following a literature search of PubMed using the terms "aceclofenac" and "clinical trials" published from 1 Jan 1992 to 1 Jan 2020. Aceclofenac is at least as effective as other NSAIDs in reducing pain and/or improving functional capacity in chronic pain conditions (OA, AS, RA, and LBP). It is generally well tolerated and appears to have a more favorable GI profile than other NSAIDs. Thus, current evidence indicates that aceclofenac is a useful option for the management of pain and inflammation across a wide range of painful conditions.

Abstract
Aceclofenac (AC) is a nonsteroidal anti-inflammatory drug used in the treatment of chronic pain in conditions such as rheumatoid arthritis, with frequent administration during the day. The formulation of sustained release matrix pellets can provide a promising alternative dosage form that controls the release of the drug, with less blood fluctuation and side effects—especially those related to the gastric system. The extrusion/spheronization technique was used to formulate AC matrix pellets. The response surface methodology (version 17.2.02.; Statgraphics Centurion) was used to study the impacts of Eudragit RL 100 and PVP K90 binder solution concentrations on the pellets’ wet mass peak torque, pellet size, and the release of the drug. Statistically, a significant synergistic effect of PVP K90 concentration on the peak torque and pellet size was observed (p = 0.0156 and 0.031, respectively), while Eudragit RL 100 showed significant antagonistic effects (p = 0.042 and 0.013, respectively). The peak torque decreased from 0.513 ± 0.022 to 0.41 ± 0.021 when increasing the Eudragit RL 100 from 0 to 20%, and the pellet size decreased from 0.914 ± 0.047 to 0.789 ± 0.074 nm. The tested independent factors did not significantly affect the drug release in the acidic medium within 2 h, but these pellet formulae maintained the drug release at less than 10% in the acidic medium (pH 1.2), which may decrease gastric irritation side effects. In contrast, a highly significant synergistic effect of Eudragit and highly antagonistic effect of the PVP solution on drug release in the alkaline-pH medium were observed (p = 0.002 and 0.007, respectively). The optimized pellet formula derived from the statistical program, composed of 3.21% Eudragit and 5% PVP solution, showed peak torque of 0.861 ± 0.056 Nm and pellet size of 1090 ± 85 µm, and resulted in a significant retardation effect on the release after 8 h compared to the untreated drug.

Abstract
Poor physicomechanical properties and limited aqueous solubility restrict the bioavailability of aceclofenac when given orally. To improve its above properties, aceclofenac (ACE) was cocrystallized with dimethyl urea (DMU) in 1:2 molar ratio by dry and solvent assisted grinding. The cocrystals were characterized by ATR-FTIR, DSC, and PXRD, and their surface morphology was studied by SEM. There was enhancement in intrinsic dissolution rate (IDR) (~eight- and ~fivefold in cocrystals prepared by solvent assisted grinding (SAG) and solid state grinding (SSG), respectively, in 0.1 N HCl, pH 1.2) and similarly (~3.42-fold and ~1.20-fold in phosphate buffer, pH 7.4) as compared to pure drug. Additionally, mechanical properties were assessed by tabletability curves. The tensile strength of ACE was < 1 MPa in contrast to the cocrystal tensile strength (3.5 MPa) which was ~1.98 times higher at 6000 psi. The tablet formulation of cocrystal by direct compression displayed enhanced dissolution profile (~36% in 0.1 N HCl, pH 1.2, and ~100% in phosphate buffer, pH 7.4) in comparison to physical mixture (~ 30% and ~ 80%) and ACE (~18% and ~50%) after 60 min, respectively. Stability studies of cocrystal tablets for 3 months indicated a stable formulation. Pharmacokinetic studies were performed by using rabbit model. The AUC0-∞ (37.87±1.3 μgh/ml) and Cmax (6.94±2.94 μg/ml) of the selected cocrystal C1 prepared by SAG were significantly enhanced (p < 0.05) and were ~3.43 and ~1.63-fold higher than that of ACE. In conclusion, new cocrystal of ACE-DMU was successfully prepared with improved tabletability, in vitro and in vivo properties.

Abstract
AIM Current work focuses on the improvement of the solubility and dissolution of ACF by the cocrystal approach. BACKGROUND Aceclofenac (ACF) is one of the commonly used Nonsteroidal Anti-Inflammatory Drug (NSAID) representing a variety of therapeutic applications including management of pain, inflammation, rheumatoid arthritis, and osteoarthritis, etc. But very low solubility and dissolution rate of ACF compromise its therapeutic utility. Now a day's cocrystallization technique has emerged as a novel technique for modulation of the said problems. OBJECTIVE The Specific objectives of this research work were mechanochemical synthesis, characterization, and performance evaluation of aceclofenac cocrystal. METHODS ACF was screened with various pharmaceutically acceptable coformers (Selected from GRAS and EAFUS list) using MOPAC software and physical screening method to find out novel cocrystals of ACF with enhanced solubility and dissolution rate. Novel cocrystals (multi-component crystalline solid) of ACF with l-cystine were prepared by a neat grinding method and by liquid assisted grinding method. The synthesized cocrystals (ACF-l-CYS NG and ACF-l-CYS LAG) were characterized carefully by Differential Scanning Calorimetry (DSC), Infrared Spectroscopy (IR), and Powder XRay Diffraction (PXRD) to verify the formation of the cocrystals. Pharmaceutically significant properties such as powder dissolution rate, solubility, and stability of the prepared cocrystals were evaluated. RESULTS Compared to pure ACF, the prepared cocrystals showed superior solubility and dissolution rate. The prepared cocrystals were found to be stable and non-hygroscopic under study conditions. CONCLUSION The cocrystallization technique was successfully utilized to increase the solubility and dissolution rate of aceclofenac.

Abstract
Aceclofenac (ACE), a cyclooxygenase-2 inhibitor, is the derivative of the diclofenac group that has been in use for the symptomatic treatment of systemic inflammatory autoimmune disease, rheumatoid arthritis (RA). Partial solubility, high lipophilic nature, and stability challenge its use in developing topical formulations. Hence, we developed and characterized nanostructured lipid carrier (NLC)-based ACE (ACE-NLC) hydrogel for an efficient transdermal delivery. NLC microemulsion was prepared using different lipids by various methods and was characterized with respect to particle size, zeta potential, surface morphology, and drug encapsulation efficiency. The optimized NLC formulation was incorporated into Carbopol® 940 gel, and this arrangement was characterized and compared with the existing marketed gel (Mkt-gel) formulation to assess in vitro drug release, rheology, texture profile, in vivo skin retention and permeation, and stability. Furthermore, prepared and characterized ACE-loaded NLC formulation was evaluated for skin integrity and fitted in a dermatokinetic model. The results of this study confirmed the spherical shape; smooth morphology and nanometric size attested by Zetasizer and scanning and transmission electron microcopy; and stability of the ACE-NLC formulation. The ACE-NLC-gel formulation showed good rheological and texture characteristics, and better skin distribution in the epidermis and dermis. Moreover, ACE-NLC permeated deeper in the skin layers and kept the skin integrity intact. Overall, NLC-based gel formulation of ACE might be a promising nanoscale lipid carrier for topical application when compared with the conventional Mkt-gel formulation.

Abstract
AIM To evaluate the effectiveness and tolerability of the drug in patients with undifferentiated peripheral inflammatory arthritis (UPIA). MATERIALS AND METHODS We observed 60 patients (39 women and 21 men) met G. Hazlewood et al., UPIA criteria, 2011. Patients were divided into 3 groups: with monoarthritis, oligoarthritis and polyarthritis. They took aceclofenac 100 mg twice day for 3 weeks. RESULTS We noted significant decreasing in pain level according to visual analogue scale: in patients with monoarthritis by 69.3 mm (p0.001); in oligoarthritis group by 47.5 mm (p0.001), in patients with polyarthritis by 30 mm (p0.001). The life quality by the EQ-5D-5L index was improved too in all groups from 0.616 to 0.829 (p0.001). The satisfaction with the therapy was: in monoarthritis patients (80% of patients and 93% of doctors noted good results), in oligoarthritis group (53% and 39% accordingly) and polyarthritis (74% and 64% respectively). We suppose the difference was due to the fact that mono- and oligoarthritis patients suffered from initial forms of seronegative spondylarthropathy, in which the effectiveness of NSAIDs is traditionally higher; polyarthritis patients probably had debut of rheumatoid arthritis. Adverse events of therapy were mild. We noted gastrointestinal tract symptoms (dyspepsia) and increased ALT in 10 patients and increased blood pressure in 1 patient. The symptoms did not require discontinuation of therapy. Сonclusion. Post-registration observational study of first Russian generic aceclofenac (Alental, Vertex, Russia) was conducted. In UPIA patients aceclofenac therapy was most effective in mono- and oligoarthritis patients. The first Russian generic aceclofenac (Alental, Vertex, Russia) has good efficacy, tolerability and safety and can be recommended for arthritis treatment.

Abstract
Background The aim of management of acute low back pain is to alleviate the pain quickly and improve functional ability. Non-steroidal anti-inflammatory drugs are the first line of treatment. The challenge lies in deciding which NSAIDs will provide greater symptomatic relief, while also being cost-effective. Objective To compare the effectiveness of aceclofenac and etoricoxib in the management of acute low back pain. Methods This prospective, open label, observational study was conducted at a tertiary care hospital. Patients over 18 years of age and presenting with low back pain of less than 6 weeks duration were enrolled in the study. Fifty patients with non-specific low back pain were randomized into two groups: Group A received aceclofenac (2 mg/kg) twice a day and Group B received etoricoxib (1 mg/kg) twice a day for 1 week. The Numerical Rating Scale (NRS) and Oswestry Low Back Disability Index (ODI) determined the clinically meaningful outcomes. Results The decrease in pain intensity in Group A was 52.27%, while in Group B it was 62.53%. However, the decrease in pain scores between the groups was not statistically significant (p = .3795). Improvement in functional ability in Group A and Group B was 57.01% and 61.48%, respectively. However, this improvement between the groups was not statistically significant (p > .999) at the end of 1 week. The average cost-effectiveness ratio indicated that etoricoxib was the dominant treatment over aceclofenac. Therefore, etoricoxib was found to be the cost-effective option for short-term pain relief in acute low back pain for 1 week. Conclusion Both aceclofenac and etoricoxib were clinically effective in reducing the pain intensity and in improving functional ability. However, etoricoxib was found to be the cost-effective intervention.

Abstract
AIM To perform a chemoreactome modeling of the pharmacological central effects of 4 non-steroidal anti-inflammatory drugs (NSAIDs): dexketoprofen, ketoprofen, aceclofenac, lornoxicam. MATERIAL AND METHODS An analysis of the pharmacological spectrum of the central action of dexketoprofen, ketoprofen, aceclofenac and lornoxicam was based on the chemoinformatic approach, which compared drug-likeness properties with public and commercial software. RESULTS The effectiveness of NSAIDs is related to the inhibition of cannabinoid receptors CB-1, the vanilloid receptor TRPV1, NMDA and AMPA receptors and of the GABA reuptake transporter, with dexketoprofen being the most effective inhibitor. The safety of the central effects of NSAID is due to weak interactions of the NSAIDs studied with opioid, adrenergic, serotonin and dopamine receptors. Chemoreactome modeling made it possible to compare the particulars of the effects of the studied NSAIDs on experimental pain and cramps. CONCLUSION Inhibition of CB-1, TRPV1, NMDA, AMPA, GABA transporter by the NSAID molecules corresponds to a decrease in the intensity of nociceptive signals. A weak intervention of the studied NSAIDs in opioid, adrenergic, serotonin and dopaminergic neurotransmission corresponds to a decrease in the central side-effects of NSAIDs and to a lessened antagonism of these NSAIDs towards exogenous and endogenous opioids.

Abstract
Dorsopathies are one of the most common pathologies in the practice of a neurologist and therapist. Lower back pain as a leader in years lived with disability. Clinical differential diagnosis using red flags can significantly reduce the proportion of patients with unreasonable examinations. Stratifying patients for the risk of chronic pain and delayed recovery also reduces the risks of prolonged NSAID therapy. Identification of risk groups for cardiovascular and gastrointestinal complications and differentiated prescription of drugs helps to reduce the risks of therapy.

Abstract
The aim of the current investigation is to delineate the buccal applicability of an in situ composite gel containing aceclofenac (AC) amino methacrylate copolymer microparticles (MPs), surmounting limitations of oral existing conventional therapy. AC Eudragit RL100 MPs were fabricated and statistically optimized using 2241 factorial design. Better buccal applicability and enhanced localization were achieved by combining the optimum MPs with in situ ion-activated gellan gum gel. The crosslinking and gelation of in situ gel were investigated by morphological and solid state characterizations. Suitability for buccal delivery and in vivo therapeutic efficacy in inflammation model of rats were also assessed. Results showed that the best performing formula displayed particle size (PS) of 51.00 µm and high entrapment efficiency (EE%) of 94.73%. MPs were successfully entrapped inside the gel network of the composite system. Gelation tendency, pH, shear-thinning properties and mucoadhesivity of the prepared in situ composite gel guaranteed its buccal suitability. Sustained AC release features and promising in vitro anti-arthritic response were also demonstrated. Moreover, consistent and prolonged in vivo anti-inflammatory effect was achieved, relative to standard AC. Taken together; this study proves the potential of in situ composite gel as an appropriate therapeutic proposal for AC buccal delivery.

Abstract
One of the most important aspects of postsurgical care is finding an efficient way for the management of pain. Third molar extractions/surgical impaction is one of the most frequent surgical procedures in dental hospitals, and it is most often associated with postoperative complications like severe pain, oedema and reduced mouth opening. This study was aimed to evaluate the efficacy of 2 g intravenous (IV) vitamin C compared to 100 mg aceclofenac on postsurgical pain, swelling and trismus after the surgical removal of third molars. A total of 101 patients were recruited for the study, and theywere divided into two treatment groups; group A (n = 51) received 2 g IV vitamin C and group B (n = 50) received 100 mg aceclofenac. Pain intensity, facial swelling and mouth opening were assessed till day 3 post-surgically. Statistical analysis of pain intensity revealed that IV vitamin C performed slightly better but not significantly different (p>0.05) from aceclofenac group at the end of day 3. No significant difference for facial swelling and mouth opening between the two treatment protocols was seen (p>0.05). Our results concluded that both treatment groups were overall similar in analgesic efficacy, postoperative oedema and reduction in mouth opening. It was also determined that the method devised administering 2 g IV vitamin C intravenously was well suited to the treatment of postoperative pain, swelling and trismus following the surgical extraction of impacted third molars.

Abstract
Aceclofenac-loaded poly(vinyl-pyrrolidone)-based nanofiber formulations were prepared by electrospinning to obtain drug-loaded orally disintegrating webs to enhance the solubility and dissolution rate of the poorly soluble anti-inflammatory active that belongs to the BCS Class-II. Triethanolamine-containing ternary composite of aceclofenac-poly(vinyl-pyrrolidone) nanofibers were formulated to exert the synergistic effect on the drug-dissolution improvement. The composition and the electrospinning parameters were changed to select the fibrous sample of optimum fiber characteristics. To determine the morphology of the nanofibers, scanning electron microscopy was used. Fourier transform infrared spectroscopy (FT-IR), and differential scanning calorimetry (DSC) were applied for the solid-state characterization of the samples, while the drug release profile was followed by the in vitro dissolution test. The nanofibrous formulations had diameters in the range of few hundred nanometers. FT-IR spectra and DSC thermograms indicated the amorphization of aceclofenac, which resulted in a rapid release of the active substance. The characteristics of the selected ternary fiber composition (10 mg/g aceclofenac, 1% w/w triethanolamine, 15% w/w PVPK90) were found to be suitable for obtaining orally dissolving webs of fast dissolution and potential oral absorption.

Abstract
In the contemporary medical model world, the proniosomal system has been serving as a new drug delivery system that is considered to significantly enhance the bioavailability of drugs with low water solubility. The application of this system can improve the bioavailability of aceclofenac that is used for the relief of pain and inflammation in osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis. The present study is intended to develop an optimized proniosomal aceclofenac formula by the use of different carriers. Aceclofenac proniosomes have been prepared by slurry method, and different carriers such as maltodextrin, mannitol, and glucose were tried. Prepared proniosomes characterized by differential scanning calorimetry (DSC) analysis and Fourier transform infrared (FTIR) analysis revealed the compatibility of the drug chosen with the ingredient added, powder X-ray diffractometry (XRD) confirmed the amorphous phase of the prepared proniosomes, and finally, the surfactant layer was observed by scanning electron microscopy (SEM). Aceclofenac physical state transformations were confirmed with all formulas but maltodextrin proniosomes exhibited solubility more than other formulations. HPLC method has been used to analyze the niosomes derived from proniosomes in terms of their entrapment capability and drug content. The obtained results revealed that aceclofenac proniosomes can be successfully prepared by using different carriers.

Abstract
BACKGROUND Multimetal organic frameworks (M-MOFs) were synthesized by including a second metal ion with the main base metal in the synthesis process to enhance their applications for drug delivery. Aceclofenac (ACF), a nonsteroidal anti-inflammatory analgesic drug of low aqueous solubility, was selected as a candidate for the drug delivery system. PURPOSE This study aimed to evaluate the loading capacity (LC) and entrapment efficiency (EE) percentages of multi-Material of Institute Lavoisier (MIL)-100(Fe) (M-MIL-100(Fe)) for ACF. MATERIALS AND METHODS Hydrothermal synthesis procedure was used to prepare multi-MIL-100(Fe) samples (Zn I-MIL-100(Fe), Zn II-MIL-100(Fe), Ca I-MIL-100(Fe), Ca II-MIL-100-(Fe), Mg I-MIL-100(Fe), Mg II-MIL-100(Fe), Mn I-MIL-100(Fe), and Mn II-MIL-100(Fe)). The characterization of M-MIL-100(Fe) samples was evaluated by X-ray powder diffraction (XRD), Fourier transform infrared spectra, scanning electron microscope (SEM), TGA, and N2 adsorption isotherms. The LC of M-MIL-100(Fe) and EE of ACF were determined. Nuclear magnetic resonance (NMR) and zeta-potential analyses were employed to confirm qualitatively the drug loading within M-MIL-100(Fe). RESULTS The ACF LC of MIL-100(Fe) was 27%, whereas the LC of M-MIL-100(Fe) was significantly increased and ranged from 37% in Ca I-MIL-100(Fe) to about 57% and 59% in Mn II-MIL-100(Fe) and Zn II-MIL-100(Fe), respectively. The ACF@M-MOFs release profiles showed slow release rates in phosphate buffer solutions at pH 6.8 and 7.4 as compared to the ACF@MIL-100(Fe). CONCLUSION Therefore, M-MOFs showed a significant potential as a carrier for drug delivery systems.

Abstract
This study examined the effects of esomeprazole on aceclofenac pharmacokinetics and gastrointestinal complications in rats. Aceclofenac alone, or in combination with esomeprazole, was orally administered to male Sprague-Dawley rats. Plasma concentrations of aceclofenac, its major metabolite diclofenac, and esomeprazole were simultaneously determined by a novel liquid chromatography-tandem mass spectrometry method. Gastrointestinal damage was determined by measuring ulcer area and ulcer lesion index of the stomach. Oral administration of aceclofenac induced significant gastric ulceration, which was inhibited by esomeprazole administration. Following concurrent administration of aceclofenac and esomeprazole, overall pharmacokinetic profiles of aceclofenac and metabolic conversion to diclofenac were unaffected by esomeprazole. Aceclofenac metabolism and pharmacokinetics were not subject to significant food effects, whereas bioavailability of esomeprazole decreased in fed compared to fasting conditions. In contrast, the pharmacokinetics of aceclofenac and esomeprazole were significantly altered by different dosing vehicles. These results suggest that co-administration of esomeprazole with aceclofenac may reduce aceclofenac-induced gastrointestinal complications without significant pharmacokinetic interactions. The optimal combination and clinical significance of the benefits of the combination of aceclofenac and esomeprazole need to be further evaluated.

Abstract
AIM To identify factors affecting the effectiveness of NSAIDs in patients with OA and LBP. MATERIALS AND METHODS An observational study was conducted to evaluate the effectiveness of a 2-week course of NSAIDs in OA and LBP in real clinical practice. The study group consisted of 3604 patients with OA and LBP (60.6% women and 39.4% men, mean age 55.0±13.4 years). According to the study design, aceclofenac (Airtal) and other NSAIDs used in the ratio 1:1. The main criterion of effectiveness was the frequency of complete pain relief after 2 weeks of therapy. In addition, the decrease of pain and general health were determined on a 10-point numerical rating scale (NRS). We compared the frequency of complete pain relief in patients who had and did not have the studied factors. The value of the studied factors was determined using OR (95% CI). RESULTS Most patients received aceclofenac (54.9%), as well as diclofenac (2.0%), ketoprofen (1.9%), lornoxicam (2.2%), meloxicam (13.7%), naproxen (2.1%), nimesulide (5.8%), celecoxib (5.9%), ethicoxib (7.1%) and other NSAIDs (4.4%); 56.2% of patients received muscle relaxants, mainly tolperisone (74.7%), vitamin B (10.4%), and proton pump inhibitors (42.8%). Complete pain relief was achieved in 54.8% of patients. The pain decrease and general health improvement were (for NRS) 63.9±13.4% and 61.7±14.8%, respectively. The efficacy of aceclofenac was slightly higher than in the whole group: complete pain relief was in 59.9% of patients. Adverse events in aceclofenac use were observed in 2.3% of patients, other NSAIDs-from 2.4 to 14.1%. The frequency of complete pain relief was higher in men: OR 1,239 (95% CI 1.08-1.418; p=0.002), who had the first episode of pain - OR 3.341 (95% CI 2.873-3.875; p=0.000), a good" response " to NSAIDs in history - OR 1.656 (95% CI 1.385-1.980; p=0.000) and received NSAIDs in combination with muscle relaxants - OR 1.218 (95% CI 1.067-1.390; p=0.004). The effect of therapy is lower in patients 65 years and older-OR 0,378 (95% CI 0.324-0.442; p=0,000), with body mass index >30 kg/m² - OR 0.619 (95% CI 0.529-0.723; p=0.000), with severe pain (≥7 points NRS) - OR 0.662 (95% CI 0.580-0.756; p=0.002), with pain at rest, - OR 0.515 (95% CI 0.450-0,589; p=0.000), pain at night - OR 0.581 (95% CI 0.501-0.672; p=0.000) and the presence of stiffness - OR 0.501 (95% CI 0.438-0,573; p=0.000). Treatment results are significantly worse in the cases of combination of LBP and joint pain, as well as pain in the trochanter major and pes anserinus area (p<0.001). CONCLUSION NSAIDs are the first-line medications for the pain treatment in LBP and OA. Aceclofenac is effective and safe in this conditions. When carrying out analgesic therapy should take into account factors that affect the effectiveness of treatment: old age, overweight, insufficient effect of NSAIDs in history, severe pain, signs of "inflammatory" pain, multiple sources of pain.

Abstract
AIM To evaluate the efficacy of pregabalin in the therapy of chronic pain in patients with knee osteoarthritis (KOA). SUBJECTS AND METHODS The study enrolled 60 patients with KOA and neuropathic pain component (NPC) (Douleur Neuropathique en 4 questions (DN4) questionnaire scores, >4) who were randomized into two groups to receive aceclofenac or aceclofenac + pregabalin for 5 weeks. All the patients underwent clinical and neurological examinations, assessment of the functional WOMAC index, pain intensity at rest and during movement, and diagnosis of neuropathic pain (NP) (DN4 and Pain DETECT questionnaires). RESULTS Both groups were observed to have positive changes in the studied parameters; however, combination therapy using an anticonvulsant drug (pregabalin) showed a more pronounced positive effect against not only NPC, but also the functional activity (WOMAC) and severity of pain (visual analogue scale). CONCLUSION Combination therapy using pregabalin in KOA patients having the signs of NP is more effective than monotherapy with nonsteroidal anti-inflammatory drugs (aceclofenac).

Abstract
AIM To evaluate the efficiency of therapy for acute/subacute musculoskeletal pain (MSP) by applying an individualized pathogenetic approach (an algorithm) elaborated on the basis of Russian experts' recommendations. SUBJECTS AND METHODS A total of 262 physicians treating patients with rheumatic diseases participated in the ATUSA (Analgesic Treatment Using a Systemic Algorithm) program. The study enrolled 3,304 patients (54.3% women, 45.7% men; mean age, 48.6±14.3 years) with osteoarthritis, nonspecific back pain (NBP), and rheumatic diseases of periarticular soft tissues, who had experienced MSP. Treatment was performed in accordance with the following algorithm: the first prescribed medication was nonsteroidal anti-inflammatory drugs (NSAIDs) (aceclofenac): paracetamol and/or tramadol and a topical NSAID in case of contraindications and muscle relaxants in case of indications. The results of treatment were assessed after 7, 14, and 28 days. The treatment was corrected during each visit; the NSAID was, if necessary, changed; corticosteroids were locally injected; antidepressants or anticonvulsant drugs were used. The investigators assessed dynamic changes in pain using a 0-10 paint intensity numeric rating scale (NRS), the number of patients, in whom MSP was completely relieved, and satisfaction with treatment. RESULTS The first prescribed medication was oral NSAIDs in 97.5% of the patients and those in combination with a muscle relaxant in 67.6%. By visit 4, MSP decreased from 6.9±1.5 to 2.2±1.3 NRS scores. After 28 days, only 16.2% of patients continued to need analgesics. 88.4% of the patients rated treatment results as good or excellent. NSAID switching was required in 8.1% of cases; local glucocorticosteroid injections were needed in 1.9%; there was a need for the use of an antidepressant or anticonvulsant in 1.5% and for hospitalization in 0.25%. Adverse events were observed in 2.2% of patients. The efficiency of treatment (complete pain relief after 28 days) was influenced by the following factors: NRS diagnosis (OR, 2.24; 95% CI, 1.67 to 3.11), age ≥65 years (OR, 0.72; 95% CI, 0.52 to 0.98), moderate pain (NRS scores of ≤7) at the beginning of the study (OR, 2.63; 95% CI, 1.99 to 3.48), mild/moderate pain (NRS scores of <4) after 7 days of therapy (OR, 2.5; 95% CI, 1.89 to 3.33), and the use of muscle relaxants (OR, 1.77; 95% CI, 1.23 to 2.96) (p<0.05 for all comparisons). CONCLUSION The comprehensive pathogenetic approach used in analgesic therapy provides an effective and relatively safe relief of MSP in most patients with NBP and osteoarthritis.

Abstract
JOINS (SKI306X) is an herbal anti-arthritic medicine that is widely used with aceclofenac for treating osteoarthritis in Korea. A fixed-dose combination (FDC) tablet containing SKI306X and aceclofenac was developed to improve patient compliance. This study aimed to compare the pharmacokinetics (PK) and safety of the FDC tablet with those of co-administered SKI306X and aceclofenac in healthy subjects. In this randomized, open-label, two-way crossover, single-dose study, the FDC tablet (SKI306X 300 mg/aceclofenac 100 mg) (test) was given or co-administration of 300 mg of SKI306X and 100 mg of aceclofenac (reference) was performed followed by a 7-day wash-out period. Blood samples were collected before and after drug administration to evaluate aceclofenac PK parameters, and safety was assessed throughout the study. A total of 54 healthy male subjects were enrolled in and completed the study. Tmax and t1/2 of aceclofenac of the FDC tablet were similar to those of aceclofenac co-administered with SKI306X (Tmax: test 2.96 h and reference 2.14 h; t1/2: test 3.46 h and reference 4.04 h). The geometric mean ratios (90% confidence intervals) of Cmax and AUClast (T/R) were 0.85 (0.81 to 0.91) and 1.03 (1.01 to 1.06) respectively; these results were within the predefined range (0.8 to 1.25). There was only one drug-related adverse event (dizziness) occurred after administration of the FDC tablet; however, it was mild in severity and resolved without any complications. The FDC tablet was well tolerated and exhibited an absorption rate and extent comparable to those of SKI306X and aceclofenac administered simultaneously.

Abstract
The aim of the present work was to tackle the solubility issue of a biopharmaceutics classification system (BCS)-II drug, aceclofenac. Although a number of attempts to increase the aqueous solubility have been made, none of the methods were taken up for scale-up. Hence size reduction technique by a top-down approach using wet milling process was utilized to improve the solubility and, consequently, the dissolution velocity of aceclofenac. The quality of the final product was ensured by Quality by Design approach wherein the effects of critical material attributes and critical process parameters were assessed on the critical quality attributes (CQAs) of nanocrystals. Box–Behnken design was applied to evaluate these effects on critical quality attributes. The optimized nanocrystals had a particle size of 484.7±54.12 nm with a polydispersity index (PDI) of 0.108±0.009. The solid state characterization of the formulation revealed that the crystalline nature of the drug was slightly reduced after the milling process. With the reduced particle size, the solubility of the nanocrystals was found to increase in both water and 0.1 N HCl when compared with that of unmilled pure aceclofenac. These results were further supported by in vitro release studies of nanocrystals where an appreciable dissolution velocity with 100.07%±2.38% release was observed for aceclofenac nanocrystals compared with 47.66%±4.53% release for pure unmilled aceclofenac at the end of 2 h. The in vivo pharmacokinetic data generated showed a statistically significant increase in the Cmax for aceclofenac nanocrystals of 3.75±0.28 µg/mL (for pure unmilled aceclofenac Cmax was 1.96±0.17 µg/mL). The results obtained indicated that the developed nanocrystals of aceclofenac were successful in improving the solubility, thus the absorption and bioavailability of the drug. Hence, it may be a viable and cost-effective alternative to the current therapy.

Abstract
The present study was aimed to coencapsulate methotrexate (MTX) and aceclofenac (ACL) in fucose anchored lipid-polymer hybrid nanoparticles (Fu-LPHNPs) to achieve target specific and controlled delivery for developing therapeutic interventions against breast cancer. The effective combination therapy requires coadministration of drugs to achieve synergistic effect on tumor with minimum adverse effects. Present study investigates the potential of codelivery of MTX and ACL through LPHNPs in MCF-7 and triple negative breast cancer cells (MDA-MB-231). We obtained LPHNPs in the nanosize range (<150 nm) with better particle size distribution (<0.3). The entrapment and loading efficiency of MTX and ACL was calculated as 85-90% and 10-12%, respectively. The coumarin-6 LPHNP formulations showed rapid internalization within 2 h incubation with MCF-7 and MDA-MB-231 cells. With 8-10 times, greater bioavailability of drug-loaded LPHNPs than free MTX and ACL was obtained. Also, antitumor efficacy of MTX- and ACL-loaded LPHNPs was determined on DMBA-induced experimental breast cancer mouse model. This model showed better control over tumor growth with MTX- and ACL-loaded LPHNPs than the combination of MTX and ACL or MTX alone. ACL-loaded LPHNPs showed prophylactic and anticancer activity in DMBA-induced mouse model at higher dose (10 mg/kg). ACL-LPHNPs confer synergistic anticancer effect when administered in combination with MTX. In conclusion, ACL enhances the therapeutic and anticancer efficacy of MTX, when coencapsulated into fucose-anchored LPHNPs, as confirmed by cell viability and serum angiogenesis (IL-6, TNF-α, IL-1β, COX2, and MMP1) at both transcript and proteome level.

Abstract
PURPOSE Nonsteroidal anti-inflammatory drugs are a mainstay for medical treatment of chronic lower back pain (CLBP). Increased dose intervals for medication have been associated with increased patient adherence to prescriptions. The purpose of this clinical trial was to compare the efficacy and safety of a once daily dose of aceclofenac controlled release (CR) and a twice daily dose of aceclofenac for CLBP management. MATERIALS AND METHODS A prospective, randomized, single center, open-label clinical trial was performed to compare the efficacy and safety of aceclofenac CR (200 mg once daily) to aceclofenac dose (100 mg twice daily). Fifty patients in each group were enrolled for the study. The primary end point was Visual Analogue Scale (VAS) change at baseline to that at 2 weeks after medication and safety profiles. Also, change in quality of life measured by EuroQoL 5D (EQ-5D) and Oswestry Disability Index (ODI) functional score for the lumbar spine were also assessed. RESULTS Within groups at pre- and post-treatment, there were significant VAS reductions for aceclofenac CR and aceclofenac (p=0.028). EQ-5D increased significantly in both groups (p=0.037). ODI scores decreased significantly in both groups (p=0.012). However, there were no significant differences between aceclofenac CR and aceclofenac at pre- and post-treatment. Patients with aceclofenac CR showed significant increases in heartburn and indigestion and adverse gastrointestinal effects, compared to aceclofenac. CONCLUSION In patients with CLBP, aceclofenac CR and aceclofenac demonstrated significant symptomatic pain relief, improvement in quality of life and functional scores. Aceclofenac CR slightly increased gastrointestinal adverse effects, such as heartburn and indigestion.

Abstract
OBJECTIVE To analyze the effects on pain, function, and safety of aceclofenac compared with other nonsteroidal anti-inflammatory drugs (NSAIDs) or pain relief medications in patients with osteoarthritis. MATERIAL AND METHODS Two investigators independently searched the database. We included randomized controlled trials evaluating efficacy and/or safety of aceclofenac compared with control interventions (NSAIDs or acetaminophen) in patients with osteoarthritis. We did not include placebo, opioid analgesics, NSAID combinations, and topical analgesics for the control groups. We summarized the efficacy data as standardized mean differences (SMD) with 95% confidence intervals (CI) and safety outcomes as risk ratios (RR) with 95% CI using the inverse variance random effect model. We assessed the heterogeneity by the I2 test. We used the GRADE approach to evaluate the quality of the evidence for all outcome parameters. RESULTS We included 9 trials (8 double blind and 1 single blind) that evaluated pain (7 trials), function (8 trials) and safety (7 trials). We observed no significant difference in pain reduction between aceclofenac and control interventions [SMD: -0.30 (-0.62, 0.01); I2=88%; GRADE evidence- low]. Aceclofenac was more beneficial than control interventions in improving physical function [SMD: -0.27 (-0.50, -0.03); I2=88%; GRADE evidence- low]. We observed less gastrointestinal adverse events for aceclofenac than in control interventions [RR 0.69 (95% CI: 0.57, 0.83); I2=12%; GRADE evidence- moderate]. We observed no difference in overall adverse events occurrence and dropout rate between aceclofenac and control interventions. CONCLUSION We observed that aceclofenac was beneficial over control analgesics for function improvement and to minimize gastrointestinal adverse events. Our findings could be biased due to the heterogeneity of the sample, the fact that the trials were small and methodological issues.

Abstract
A nontargeted approach based on liquid chromatography equipped with a quadrupole time-of-flight mass detector (LC-MS Q-TOF) joined to nuclear magnetic resonance (NMR) analysis allowed rapid identification and quantification of the anti-inflammatory drug aceclofenac in illegal Adderall tablets. The largest chromatographic peak had m/z = 354.030 and m/z = 376.012 matching, respectively, the ionic structures (M + H)+ and (M + Na)+ of a molecule M. The accurate mass data generated the molecular formula C16 H13 Cl2 NO4 . A screening of the pharmaceutical active substances having that molecular formula together with the MS/MS fragmentation pattern suggested aceclofenac. Aceclofenac structure was unambiguously confirmed by 1 H and 13 C NMR experiments. The aceclofenac content was 90 mg/tablet (RSD 2%) as detected by quantitative NMR. Information on the identity and content of illegal drugs is required for legal purposes; it supports in evaluating the effective impact on users safety, and it is useful for control laboratories using a targeted approach in their analytical activities.

Abstract
Drug-coated sutures are widely used as delivery depots for antibiotics and anti-inflammatory drugs at surgical wound sites. Although drug-laden coating provides good localized drug concentration, variable loading efficiency and release kinetics limits its use. Alternatively, drug incorporation within suture matrices is hampered by the harsh fabrication conditions required for suture-strength enhancement. To circumvent these limitations, we fabricated mechanically robust electrospun core-sheath yarns as sutures, with a central poly-l-lactic acid core, and a drug-eluting poly-lactic-co-glycolic acid sheath. The electrospun sheath was incorporated with aceclofenac or insulin to demonstrate versatility of the suture in loading both chemical and biological class of drugs. Aceclofenac and insulin incorporated sutures exhibited 15% and 4% loading, and release for 10 and 7 days, respectively. Aceclofenac sutures demonstrated reduced epidermal hyperplasia and cellularity in skin-inflammation animal model, while insulin loaded sutures showed enhanced cellular migration in wound healing assay. In conclusion, we demonstrate an innovative strategy of producing mechanically strong, prolonged drug-release sutures loaded with different classes of drugs.

Abstract
BACKGROUND Eperisone hydrochloride, a centrally acting muscle relaxant, is a calcium antagonist that causes vasodilation and antispastic actions. Aceclofenac, an anti-inflammatory analgesic and antipyretic drug, has similar efficacy and improved gastrointestinal tolerance compared with other nonsteroidal anti-inflammatory drugs, such as diclofenac. Although eperisone hydrochloride and aceclofenac are frequently coadministered, no published studies have reported on the pharmacokinetic interactions between these 2 drugs. OBJECTIVE The aim of this study was to investigate any pharmacokinetic interactions between eperisone hydrochloride and aceclofenac in healthy Korean men. METHODS This was a randomized, open-label, crossover study. Each participant was randomly assigned to 1 of 6 treatment sequences and received eperisone hydrochloride (3 doses of 50 mg each), aceclofenac (2 doses of 100 mg each), or both as a single dose with a 7-day washout period between each dose. Blood samples were collected ≤ 24 hours after dosing, and plasma eperisone hydrochloride and aceclofenac concentrations were determined using validated LC/MS-MS. Pharmacokinetic analyses were conducted using noncompartmental methods. A safety profile was determined using the measurement of vital signs, ECG, and clinical laboratory tests. RESULTS A total 24 of men were enrolled, and all completed the study. The geometric mean ratios (90% CIs) of the Cmax and AUC0-∞ values for eperisone were 1.18 (0.828-1.673) and 1.12 (0.836-1.507), respectively. The geometric mean ratios (90% CIs) of the Cmax and AUC0-∞ for aceclofenac were 0.93 (0.847-1.022) and 1.01 (0.979-1.036), respectively. A total of 7 adverse events were reported in 7 men. All adverse events were mild, and no significant differences were found between treatment groups. CONCLUSION No clinically significant pharmacokinetic differences exist between 150 mg eperisone hydrochloride and 200 mg aceclofenac when administrated as a monotherapy or in combination.

Abstract
Aceclofenac, a non-steroidal antiinflammatory drug, is used for posttraumatic pain and rheumatoid arthritis. Aceclofenac fast-dispersible tablets have been prepared by direct compression method. Effect of superdisintegrants (such as, croscarmellose sodium, sodium starch glycolate and crospovidone) on wetting time, disintegration time, drug content, in vitro release and stability parameters has been studied. Disintegration time and dissolution parameters (t(50%) and t(80%)) decreased with increase in the level of croscarmellose sodium. Where as, disintegration time and dissolution parameters increased with increase in the level of sodium starch glycolate in tablets. However, the disintegration time values did not reflect in the dissolution parameter values of crospovidone tablets and release was dependent on the aggregate size in the dissolution medium. Stability studies indicated that tablets containing superdisintegrants were sensitive to high humidity conditions. It is concluded that fast-dispersible aceclofenac tablets could be prepared by direct compression using superdisintegrants.

Abstract
The present study was carried out with a view to enhance the dissolution of poorly water-soluble BCS-class II drug aceclofenac by co-grinding with novel porous carrier Neusilin US(2.) (amorphous microporous granules of magnesium aluminosilicate, Fuji Chemical Industry, Toyama, Japan). Neusilin US(2) has been used as an important pharmaceutical excipient for solubility enhancement. Co-grinding of aceclofenac with Neusilin US(2) in a ratio of 1:5 was carried out by ball milling for 20 h. Samples of co-ground mixtures were withdrawn at the end of every 5 h. and characterized for X-ray powder diffraction, differential scanning calorimetry, and Fourier-transform infrared spectroscopy. The analysis revealed the conversion of crystalline aceclofenac to its amorphous form upon milling with Neusilin US(2). Further, in vitro dissolution rate of aceclofenac from co-ground mixture was significantly higher compared to pure aceclofenac. The accelerated stability study of co-ground mixture was carried out at 40 degrees C/75%RH for 4 weeks, and it showed that there was no reversion from amorphous to crystalline form. Thus, it is advantageous to use a porous carrier like Neusilin US(2) in improvement of dissolution of poorly soluble drugs.

Abstract
1. Since nonsteroidal anti-inflammatory drugs (NSAIDs) may impair the ability of the chondrocyte to repair its damaged extracellular matrix, we explored the changes in the metabolism of newly synthesized proteoglycan and hyaluronan (HA) molecules produced by aceclofenac, diclofenac and meloxicam in human osteoarthritic (OA) cartilage. 2. Explants were sampled from the medial femoral condyle and were classified by use of the Mankin's histological-histochemical grading system. Cartilage specimens exhibited moderate (M) OA in 20 subjects and had severe (S) OA in 20. 3. Cartilage explants were pulsed with [-3H]-glucosamine and chased in the absence or in the presence of 0.3 - 3 microg ml(-1) of either aceclofenac, diclofenac or meloxicam. After papain digestion, the labelled chondroitin sulphate ([-3H]-proteoglycans) and [-3H]-HA molecules present in the tissue and media were purified by anion-exchange chromatography. 4. In cartilage with MOA and SOA, the metabolic balance of proteoglycan and HA was unaffected by diclofenac. In contrast, and in a dose-dependent manner, aceclofenac and meloxicam both increased the synthesis of proteoglycans and HA in explants with MOA and SOA; these two NSAIDs also reduced significantly the net loss of [-3H]-proteoglycans and [-3H]-HA molecules from cartilage explants. 5. The data obtained in short-term in vitro cultures indicate that, at the concentrations found in synovial fluid, aceclofenac and meloxicam may exert a favourable effect on the overall metabolism of proteoglycans and HA in cartilage with MOA and SOA.
