Abstract
Keeping in mind the health scenario in Kingdom of Saudi Arabia with respect to vitamin D3 (VD3) deficiency and its significant role in calcium homeostasis and human metabolism, this research is exploring the combination of eggshell (as a source of calcium) and VD3 as a very economical solution for this problem. Eggshells from local restaurant were collected, washed, ground, sieved, and characterized by Fourier transforms infrared spectroscopy (FTIR), scanning electron microscopy (SEM), differential scanning calorimetry (DSC), X-ray diffraction (XRD), and Brunauer-Emmett-Teller (BET) techniques. The results of FTIR, SEM, DSC, XRD, and BET indicate that eggshell powder (ESP) was properly processed. Directly compressed tablets containing 2.5 mg of VD3 (equivalent to 50,000 IU), that are based on the use of ESP as tablet filler, were manufactured based on mixing Avicel PH 101 with ESP in different ratios (9:1, 1:1, and 1:9) in addition to the use of both Avicel PH 101 and ESP alone as tablet filler. Tablets properties were evaluated according to USP30-NF25 pharmacopoeia tests in terms of weight variation test, drug content uniformity, tablet hardness, tablet friability, tablet disintegration, and in vitro dissolution profile. The VD3 contents were found to be 98.77-102.35% in all formulations. After 90 min of study, all formulations showed in vitro drug release content in the range of 99.29-101.05%. All of the tested parameters of ESP tablets were similar to those of commercial Avicel PH 101. All of the tested properties of tablets with ESP as a filler were found to be within the acceptable limits of the pharmacopeia recommendations. Therefore, ESP could be exploited for its use as a filler in direct compression tablets.

Abstract
A nanoemulsion-based polyherbal mouthwash (PHFX) of Curcuma longa hydroalcoholic extract was developed and evaluated for its antibacterial effects against a variety of Gram-positive and Gram-negative oral pathogens in comparison to standard chlorhexidine acetate (CHD-A) (positive control). Various nanoemulsion-based mouthwashes of C. longa extract were produced using an aqueous phase titration approach via construction of pseudoternary phase diagrams. The developed nanoemulsion-based PHFX was studied for thermodynamic stability tests. Selected formulations (PHFX1-PHFX5) were characterized physicochemically for droplet diameter, polydispersity index (PDI), refractive index (RI), transmittance, and pH. The drug release studies were performed using the dialysis method. Based on the minimum droplet diameter (26.34 nm), least PDI (0.132), optimal RI (1.337), maximum %T (99.13), optimal pH (6.45), and maximum cumulative drug release (98.2%), formulation PHFX1 (containing 0.5% w/w of C. longa extract, 1.5% w/w of clove oil, 7.0% w/w of Tween-80, 7.0% w/w of Transcutol-HP, and 84.0% w/w of water) was selected for antimicrobial studies in comparison to standard CHD-A. The antibacterial effects and minimum inhibitory concentration were studied against various Gram-positive oral pathogens such as Streptococcus mutans, Staphylococcus aureus, Streptococcus pneumoniae, and Bacillus subtilis and Gram-negative oral pathogens such as Escherichia coli and Klebsiella pneumoniae. The antibacterial effects of PHFX1 were found to be significant over standard CHD-A against most Gram-positive and Gram-negative oral pathogens. The antimicrobial studies showed that the formulation PHFX1 was effective against all oral pathogens even at 3- to 4-fold lower working concentrations. These findings indicated the potential of nanoemulsion-based mouthwash in the treatment of a variety of oral pathogen infections.

Abstract
There is a dearth of information in the literature regarding environmentally benign high-performance thin-layer chromatography (HPTLC) methods to determine tenoxicam (TNX). Therefore, designing and validating an HPTLC method to detect TNX in commercial tablets and capsules was the goal of this investigation. The green mobile phase utilized was the combination of ethanol/water/ammonia solution (50:45:5 v/v/v). The TNX was quantified at a wavelength of 375 nm. The proposed method's greenness profile was established using the Analytical GREEnness (AGREE) approach. The proposed methodology for determining TNX was linear in the range of 25-1400 ng/band. The proposed methodology for measuring TNX was accurate (% recoveries = 98.24-101.48), precise (% RSD = 0.87-1.02), robust (% RSD = 0.87-0.94), sensitive (LOD = 0.98 ng/band and LOQ = 2.94 ng/band), and environmentally friendly. The AGREE scale for the present methodology was derived to be 0.75, indicating an outstanding greenness profile. TNX was found to be highly stable under acidic, base, and thermal stress conditions. However, it completely decomposed under oxidative stress conditions. Commercial tablets and capsules were found to have 98.46 and 101.24% TNX, respectively. This finding supports the validity of the current methodology for measuring TNX in commercial formulations. The outcomes of this work showed that the proposed eco-friendly HPTLC methodology can be used for the routine analysis of TNX in commercial formulations.

Abstract
The solubility and solution thermodynamics of isotretinoin (ITN) (3) in numerous {dimethyl sulfoxide (DMSO) (1) + water (H2O) (2)} combinations were studied at 298.2-318.2 K under fixed atmospheric pressure of 101.1 kPa. A shake flask methodology was used to determine ITN solubility, and correlations were made using the "van't Hoff, Apelblat, Buchowski-Ksiazczak λh, Yalkowsky-Roseman, Jouyban-Acree, and Jouyban-Acree-van't Hoff models". In mixtures of {(DMSO (1) + H2O (2)}, the solubility of ITN in mole fractions was enhanced with the temperature and DMSO mass fraction. The mole fraction solubility of ITN was highest in neat DMSO (1.02 × 10-1 at 318.2 K) and lowest in pure H2O (3.14 × 10-7 at 298.2 K). The output of computational models revealed good relationships between the solubility data from the experiments. The dissolution of ITN was "endothermic and entropy-driven" in all of the {(DMSO (1) + H2O (2)} mixtures examined, according to the positive values of measured thermodynamic parameters. Enthalpy was discovered to be the driving force behind ITN solvation in {(DMSO (1) + H2O (2)} combinations. ITN-DMSO displayed the highest molecular interactions when compared to ITN-H2O. The outcomes of this study suggest that DMSO has a great potential for solubilizing ITN in H2O.

Abstract
In this study, an environmentally friendly "high-performance liquid chromatography (HPLC)" assay to quantify isotretinoin (ITN) in commercial products and solubility samples is designed and verified. A Nucleodur reverse-phase C18 column was used as the stationary phase to identify ITN. The ecologically friendly mobile phase was composed of ethyl acetate and ethanol (50:50 v/v), and it was delivered at a flow rate of 1.0 mL/min. ITN was measured at 354 nm in wavelength. The current HPLC method had a determination coefficient of 0.9994 and was linear in the 0.2-80 μg/g range. The current protocol for ITN measurement was also rapid (retention time = 2.78 min), accurate (%recoveries = 98.60-101.52), precise (% uncertainties = 0.71-0.98), and sensitive. According to the AGREE methodology, the current procedure received an outstanding greenness profile with an AGREE score of 0.76. By determining ITN in commercial products and solubility samples, the applicability of the current approach was proven. ITN was discovered to be present in 98.43% and 100.84%, respectively, of commercial capsule brands A and B. The ITN's solubility in numerous eco-friendly solvents was successfully measured. Under different stress conditions, the current approach was able to distinguish between its degradation products, demonstrating its stability-indicating characteristics. These findings indicated that ITN in procured capsules and solubility samples might be regularly tested by the suggested approach.

Abstract
Eco-friendly liquid chromatographic methods for measuring ergotamine (EGT) are scant in the published database. Accordingly, the goal of the current study was to develop a high-performance thin-layer chromatography (HPTLC) method for fluorescence detection of EGT in commercially available tablets. This approach was based on the application of ethyl alcohol-water (80:20 v/v) as the eco-friendly eluent mixture. The fluorescence detection of EGT was carried out at 322 nm. The greenness score of the present approach was evaluated by "Analytical GREENness (AGREE)" technology. The present approach for measuring EGT in the 25-1000 ng band-1 range was linear. The present assay for fluorescence detection of EGT was validated successfully by ICH guidelines for various parameters. The method was found to be rapid, sensitive, eco-friendly, and stability-indicating. The computed AGREE index for the current strategy was 0.84, displaying outstanding greenness features. The present methodology successfully separated the EGT degradation products under forced-degradation circumstances, exhibiting its stability-indicating qualities and selectivity. An amount of 99.33% of EGT was found in commercial formulations, indicating the validity of the current method for pharmaceutical analysis of EGT in commercial products. The results showed that EGT in commercial products might be regularly measured by the existing method.

Abstract
Lung cancer is the main cause of cancer-related mortality globally. Erlotinib is a tyrosine kinase inhibitor, affecting both cancerous cell proliferation and survival. The emergence of oncological nanotechnology has provided a novel drug delivery system for erlotinib. The aims of this current investigation were to formulate two different polyamidoamine (PAMAM) dendrimer generations-generation 4 (G4) and generation 5 (G5) PAMAM dendrimer-to study the impact of two different PAMAM dendrimer formulations on entrapment by drug loading and encapsulation efficiency tests; to assess various characterizations, including particle size distribution, polydispersity index, and zeta potential; and to evaluate in vitro drug release along with assessing in situ human lung adenocarcinoma cell culture. The results showed that the average particle size of G4 and G5 nanocomposites were 200 nm and 224.8 nm, with polydispersity index values of 0.05 and 0.300, zeta potential values of 11.54 and 4.26 mV of G4 and G5 PAMAM dendrimer, respectively. Comparative in situ study showed that cationic G4 erlotinib-loaded dendrimer was more selective and had higher antiproliferation activity against A549 lung cells compared to neutral G5 erlotinib-loaded dendrimers and erlotinib alone. These conclusions highlight the potential effect of cationic G4 dendrimer as a targeting-sustained-release carrier for erlotinib.

Abstract
The objective of this analysis is to establish the potential of biodegradable agro-industrial waste materials as biosorbents in the solid-phase extraction (SPE) technique for sample preparation. In this regard, waste coffee husk (CH) powder was collected, washed, treated chemically, characterized, and applied as an SPE adsorbent to extract pantoprazole from the wastewater samples. Sample detection was accomplished using the UPLC-MS/MS system. The positive mode of electrospray ionization was exploited for the ionization of the sample, and quantification of the target analyte was performed by the multiple reaction monitoring modes. The precursor to product ion transition of 384.02→1380.05 and 384.02→200.05 was used as qualifiers and quantifiers, respectively. Optimization of the particle size, adsorbent dose, and contact time were evaluated to select the best combination of features. The efficiency and regeneration capability of the CH were compared with respect to a commercially available silica-based C18 SPE adsorbent, and it was found that CH possessed comparable (~50%) extraction, as well as regeneration capacity (~95%). The developed biosorbent was applied in a wastewater sample spiked with the target analyte and recovery studies were performed, which found a range of 93.0 to 102.0% with a %RSD of 3.72 to 12.7%. Thus, CH can be exploited as a ‘greener’ replacement for the commercially available adsorbents for the extraction/retention of active pharmaceutical ingredients present in water/wastewater samples.

Abstract
Background Multidrug-resistant (MDR) bacterial infections have become an emerging health concern around the world. Antibiotics resistance among S. pneumoniae strains increased recently contributing to increase in incidence of pneumococcal infection. This necessitates the discovery of novel antipnemococcal such as compound C3-005 which target the interaction between RNA polymerase and σ factors. Chitosan nanoparticles (CNPs) exhibited antibacterial activity including S. pneumonia. Therefore, the aims of the current investigation were to formulate CNPs loaded with C3-005 and characteristic their antimicrobial properties against S. pneumonia. Methods The CNPs and C3-005 loaded CNPs were produced utilizing ionic gelation method, and their physicochemical characteristics including particle size, zeta potential, polydispersity index (PDI), encapsulation efficiency (EE%), and in vitro release profile were studied. Both differential scanning calorimetry (DSC) and fourier transform infrared spectroscopy (FTIR) were used for chemical characterization. The synthesized NPs' minimum inhibitory concentration (MIC) was determined using killing assay and broth dilution method, and their impact on bacteria induced hemolysis were also studied. Results The NPs encapsulating C3-005 were successfully prepared with particle size of 343.5 nm ± 1.3, zeta potential of 29.8 ± 0.37, and PDI of 0.20 ± 0.03. 70 % of C3-005 were encapsulated in CNPs and sustained release pattern of C3-005 from CNPs was revealed by an in vitro release study. CNPs containing C3-005 exhibited higher antipnomcoccal activity with MIC50 of 30 µg/ml when compared with C3-005 and empty CNPs alone. The prepared C3-CNPs showed a reduction of bacterial hemolysis in a concentration-related (dependent) manner and was higher than C3-005 alone. Conclusions The findings of this study showed the potential for using C3-005 loaded CNPs to treat pneumococcal infection.

Abstract
The solubilization and thermodynamic analysis of isotretinoin (ITN) in eleven distinct green solvents, such as water, methyl alcohol (MeOH), ethyl alcohol (EtOH), 1-butyl alcohol (1-BuOH), 2-butyl alcohol (2-BuOH), ethane-1,2-diol (EG), propane-1,2-diol (PG), polyethylene glycol-400 (PEG-400), ethyl acetate (EA), Transcutol-HP (THP), and dimethyl sulfoxide (DMSO) was studied at several temperatures and a fixed atmospheric pressure. The equilibrium approach was used to measure the solubility of ITN, and the Apelblat, van’t Hoff, and Buchowski−Ksiazczak λh models were used to correlate the results. The overall uncertainties were less than 5.0% for all the models examined. The highest ITN mole fraction solubility was achieved as 1.01 × 10−1 in DMSO at 318.2 K; however, the least was achieved as 3.16 × 10−7 in water at 298.2 K. ITN solubility was found to be enhanced with an increase in temperature and the order in which it was soluble in several green solvents at 318.2 K was as follows: DMSO (1.01 × 10−1) > EA (1.73 × 10−2) > PEG-400 (1.66 × 10−2) > THP (1.59 × 10−2) > 2-BuOH (6.32 × 10−3) > 1-BuOH (5.88 × 10−3) > PG (4.83 × 10−3) > EtOH (3.51 × 10−3) > EG (3.49 × 10−3) > MeOH (2.10 × 10−3) > water (1.38 × 10−6). ITN−DMSO showed the strongest solute−solvent interactions when compared to the other ITN and green solvent combinations. According to thermodynamic studies, ITN dissolution was endothermic and entropy-driven in all of the green solvents tested. The obtained outcomes suggested that DMSO appears to be the best green solvent for ITN solubilization.

Abstract
The solubility of the poorly soluble medicine febuxostat (FXT) (3) in various {polyethylene glycol 400 (PEG 400) (1) + water (H2O) (2)} mixtures has been examined at 298.2-318.2 K and 101.1 kPa. FXT solubility was measured using an isothermal method and correlated with "van't Hoff, Apelblat, Buchowski-Ksiazczak λh, Yalkowsky-Roseman, Jouyban-Acree, and Jouyban-Acree-van't Hoff models". FXT mole fraction solubility was enhanced via an increase in temperature and PEG 400 mass fraction in {(PEG 400 (1) + H2O (2)} mixtures. Neat PEG 400 showed the highest mole fraction solubility of FXT (3.11 × 10-2 at 318.2 K), while neat H2O had the lowest (1.91 × 10-7 at 298.2 K). The overall error value was less than 6.0% for each computational model, indicating good correlations. Based on the positive values of apparent standard enthalpies (46.72-70.30 kJ mol-1) and apparent standard entropies (106.4-118.5 J mol-1 K-1), the dissolution of FXT was "endothermic and entropy-driven" in all {PEG 400 (1) + H2O (2)} mixtures examined. The main mechanism for FXT solvation in {PEG 400 (1) + H2O (2)} mixtures was discovered to be an enthalpy-driven process. In comparison to FXT-H2O, FXT-PEG 400 showed the strongest molecular interactions. In conclusion, these results suggested that PEG 400 has considerable potential for solubilizing a poorly soluble FXT in H2O.

Abstract
Various chitosan (CS)-based nanoparticles (CS-NPs) of ciprofloxacin hydrochloride (CHCl) have been investigated for therapeutic delivery and to enhance antimicrobial efficacy. However, the Box–Behnken design (BBD)-supported statistical optimization of NPs of CHCl has not been performed in the literature. As a result, the goal of this study was to look into the key interactions and quadratic impacts of formulation variables on the performance of CHCl-CS-NPs in a systematic way. To optimize CHCl-loaded CS-NPs generated by the ionic gelation process, the response surface methodology (RSM) was used. The BBD was used with three factors on three levels and three replicas at the central point. Tripolyphosphate, CS concentrations, and ultrasonication energy were chosen as independent variables after preliminary screening. Particle size (PS), polydispersity index (PDI), zeta potential (ZP), encapsulation efficiency (EE), and in vitro release were the dependent factors (responses). Prepared NPs were found in the PS range of 198–304 nm with a ZP of 27–42 mV. EE and drug release were in the range of 23–45% and 36–61%, respectively. All of the responses were optimized at the same time using a desirability function based on Design Expert® modeling and a desirability factor of 95%. The minimum inhibitory concentration (MIC) of the improved formula against two bacterial strains, Pseudomonas aeruginosa and Staphylococcus aureus, was determined. The MIC of the optimized NPs was found to be decreased 4-fold compared with pure CHCl. The predicted and observed values for the optimized formulation were nearly identical. The BBD aided in a better understanding of the intrinsic relationship between formulation variables and responses, as well as the optimization of CHCl-loaded CS-NPs in a time- and labor-efficient manner.

Abstract
Psoriatic arthritis is an autoimmune disease of the joints that can lead to persistent inflammation, irreversible joint damage and disability. The current treatments are of limited efficacy and inconvenient. Apremilast (APR) immediate release tablets Otezla® have 20-33% bioavailability compared to the APR absolute bioavailability of 73%. As a result, self-nanoemulsifying drug delivery systems (SNEDDS) of APR were formulated to enhance APR's solubility, dissolution, and oral bioavailability. The drug assay was carried out using a developed and validated HPLC method. Various thermodynamic tests were carried out on APR-SNEDDS. Stable SNEDDS were characterized then subjected to in vitro drug release studies via dialysis membrane. The optimum formulation was F9, which showed the maximum in vitro drug release (94.9%) over 24 h, and this was further investigated in in vivo studies. F9 was composed of 15% oil, 60% Smix, and 25% water and had the lowest droplet size (17.505 ± 0.247 nm), low PDI (0.147 ± 0.014), low ZP (-13.35 mV), highest %T (99.15 ± 0.131) and optimum increases in the relative bioavailability (703.66%) compared to APR suspension (100%) over 24 h. These findings showed that APR-SNEDDS is a possible alternative delivery system for APR. Further studies are warranted to evaluate the major factors that influence the encapsulation efficiency and stability of APR-containing SNEDDS.

Abstract
Luteolin (LUT) is a natural pharmaceutical compound that is weakly water soluble and has low bioavailability when taken orally. As a result, the goal of this research was to create self-nanoemulsifying drug delivery systems (SNEDDS) for LUT in an attempt to improve its in vitro dissolution and hepatoprotective effects, resulting in increased oral bioavailability. Using the aqueous phase titration approach and the creation of pseudo-ternary phase diagrams with Capryol-PGMC (oil phase), Tween-80 (surfactant), and Transcutol-HP (co-emulsifier), various SNEDDS of LUT were generated. SNEDDS were assessed for droplet size, polydispersity index (PDI), zeta potential (ZP), refractive index (RI), and percent of transmittance (percent T) after undergoing several thermodynamic stability and self-nanoemulsification experiments. When compared to LUT suspension, the developed SNEDDS revealed considerable LUT release from all SNEDDS. Droplet size was 40 nm, PDI was <0.3, ZP was -30.58 mV, RI was 1.40, percent T was >98 percent, and drug release profile was >96 percent in optimized SNEDDS of LUT. For in vivo hepatoprotective testing in rats, optimized SNEDDS was chosen. When compared to LUT suspension, hepatoprotective tests showed that optimized LUT SNEDDS had a substantial hepatoprotective impact. The findings of this investigation suggested that SNEDDS could improve bioflavonoid LUT dissolution rate and therapeutic efficacy.

Abstract
Sesame (Sesamum indicum L.) is an important staple crop of the family Pedaliaceae. The commercial production of sesame is still dependent on the applications of chemical fertilizers. Mycorrhiza inoculum resulted in better morphological and biochemical traits in vegetables. Thus, here the outcome of arbuscular mycorrhizal fungi (AMF) and Pseudomonas fluorescence (ATCC-17400) inoculation was studied in the pot culture experiment. Primarily, there seems to be a promising opportunity of AMF in sesame under pot and field trials because of enhanced morphological parameters, especially root weight, and disparities in nutrients and metabolites. The AMF appears to be an option to boost plant growth, mineral content, and sesame yield. The AMF treatment with Pseudomonas fluorescence strain (ATCC-17400) determined the maximum values for the morphological traits and mineral content. Overall, our study highlights mycorrhizal fungi and other microbes efficacy in achieving a successful sesame production.

Abstract
The aim of this work was to solubilize simvastatin (SIM) using different micellar solutions of various non-ionic surfactants such as Tween-80 (T80), Tween-20 (T20), Myrj-52 (M52), Myrj-59 (M59), Brij-35 (B35) and Brij-58 (B58). The solubility of SIM in water (H2O) and different micellar concentrations of T80, T20, M52, M59, B35 and B58 was determined at temperatures T = 300.2 K to 320.2 K under atmospheric pressure p = 0.1 MPa using saturation shake flask method. The experimental solubility data of SIM was regressed using van’t Hoff and Apelblat models. The solubility of SIM (mole fraction) was recorded highest in M59 (1.54 x 10−2) followed by M52 (6.56 x 10−3), B58 (5.52 x 10−3), B35 (3.97 x 10−3), T80 (1.68 x 10−3), T20 (1.16 x 10−3) [the concentration of surfactants was 20 mM in H2O in all cases] and H2O (1.94 x 10−6) at T = 320.2 K. The same results were also recorded at each temperature and each micellar concentration of T80, T20, M52, M59, B35 and B58. “Apparent thermodynamic analysis” showed endothermic and entropy-driven dissolution/solubilization of SIM in H2O and various micellar solutions of T80, T20, M52, M59, B35 and B58.

Abstract
The solubilization, Hansen solubility parameters (HSPs), and thermodynamic properties of delafloxacin (DLN) in various unique combination of Transcutol-HP® (THP) and 1-butyl-3-methyl imidazolium hexafluorophosphate ionic liquid (BMIM-PF6) mixtures were evaluated for the first time in this research. The 'mole fraction solubilities (x3)' of DLN in different (THP + BMIM-PF6) compositions were determined at 'T = 298.2-318.2 K' and 'p = 0.1 MPa'. The HSPs of DLN, neat THP, neat BMIM-PF6, and binary (THP + BMIM-PF6) compositions free of DLN were also determined. The x3 data of DLN was regressed using 'van't Hoff, Apelblat, Yalkowsky-Roseman, Jouyban-Acree and Jouyban-Acree-van't Hoff models' with overall error values of less than 3.0%. The highest and lowest x3 value of DLN was recorded in neat THP (5.48 × 10-3 at T = 318.2 K) and neat BMIM-PF6 (6.50 × 10-4 at T = 298.2 K), respectively. The solubility of DLN was found to be enhanced significantly with an arise in temperature in all (THP + BMIM-PF6) compositions including pure THP and pure BMIM-PF6. However, there was slight increase in DLN solubility with increase in THP mass fraction in all (THP + BMIM-PF6) mixtures. The HSP of pure THP and pure BMIM-PF6 were found very close to each other, suggesting the great potential of both solvents in DLN solubilization. The maximum solute-solvent interactions at molecular level were recorded in DLN-THP compared to DLN-BMIM-PF6. An 'apparent thermodynamic analysis' study indicated an 'endothermic and entropy-driven dissolution' of DLN in all (THP + BMIM-PF6) compositions including neat THP and BMIM-PF6.

Abstract
A novel, simple, and reliable ultraperformance liquid chromatography tandem-mass spectrometry (UPLC-MS/MS ) assay based on dispersive liquid-liquid microextraction followed by ultrasound-assisted reverse extraction from solidified floating organic droplets was established for determination of multiclass pharmaceuticals in the water sample. Six commonly used drugs of various therapeutic classes: ibuprofen, ketorolac, lamotrigine, propranolol, pantoprazole, and losartan were extracted from water samples by using 50 μL 1-undecanol as extracting solvent and 400 μL acetonitrile as dispersive solvent. After collecting the floating organic droplets by cold centrifugation, an ultrasound-assisted back extraction procedure was performed to make the sample compatible for UPLC-MS/MS analysis. Acquity BEH C18 column (2.1 × 100; 1.7 μm) was used for separation of target analytes that were eluted by a gradient mobile phase composition of 15 mM ammonium acetate and acetonitrile at a flow rate of 0.25 mL/min. The sample ionization was performed by using electrospray ionization in positive mode, and multiple reaction monitoring was used for quantification of target analytes. After optimizing the assay conditions, all calibration curves were found to be linear with limit of detection and limit of quantification were ranged in between 0.06-0.15 and 0.16-0.41 ng/mL, respectively. The enrichment factor was found to be 172-192-fold and the relative recovery was ranged between 93.1 and 109.4% between target analytes. These satisfactory results confirmed that the proposed method is specific and reliable for application of trace analysis of target analytes in waste water samples.

Abstract
BACKGROUND Sinapic acid (SA) has been shown to have various pharmacological properties such as antioxidant, antifibrotic, anti-inflammatory, and anticancer activities. Its mechanism of action is dependent upon its ability to curb free radical production and protect against oxidative stress-induced tissue injuries.
AIM To study the hepatoprotective effects of SA against lipopolysaccharide (LPS)/D-galactosamine (D-GalN)-induced acute liver failure (ALF) in rats.
METHODS Experimental ALF was induced with an intraperitoneal (i.p.) administration of 8 μg LPS and 800 mg/kg D-GalN in normal saline. SA was administered orally once daily starting 7 d before LPS/D-GalN treatment.
RESULTS Data showed that SA ameliorates acute liver dysfunction, decreases serum levels of alanine transaminase (ALT), and aspartate aminotransferase (AST), as well as malondialdehyde (MDA) and NO levels in ALF model rats. However, pretreatment with SA (20 mg/kg and 40 mg/kg) reduced nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) activation and levels of inflammatory cytokines (tumor necrosis factor-α and interleukin 6). Also, SA increased the activity of the nuclear factor erythroid-related factor 2/heme oxygenase-1 (Nrf2/HO-1) signaling pathway.
CONCLUSION In conclusion, SA offers significant protection against LPS/D-GalN-induced ALF in rats by upregulating Nrf2/HO-1 and downregulating NF-κB.

Abstract
In this research, an antiviral drug emtricitabine (ECT) was quantified using the validated green reversed-phase high-performance thin-layer chromatography (RP-HPTLC) and routine normal-phase HPTLC (NP-HPTLC) methods in the marketed oral solutions and capsules. Green RP-HPTLC-densitometry quantification was performed using the acetone/water (70:30, v/v) solvent system as the mobile phase. Routine NP-HPTLC-densitometry quantification was performed using the chloroform/methanol (85:15, v/v) solvent system as the mobile phase. The detection was performed at λmax-285 nm for both of the methods. Both densitometry methods were validated for different parameters. Most of the validation parameters including linearity, precision, accuracy, detection, and quantification limits for the green densitometry method were found to be superior compared to the routine densitometry technique. The ECT contents of commercial oral solution and commercial capsules were found to be 100.85 and 98.27%, respectively, using the green densitometry technique. The ECT contents of oral solutions and capsules were 97.16 and 95.54%, respectively, using the routine densitometry technique. Accordingly, the green densitometry technique was found to be better than the routine densitometry technique for ECT assays. Thus, the green densitometry technique can be successfully applied for the quantitation of ECT in the marketed formulations.

Abstract
Purpose:
Hepatocellular carcinoma (HCC) is a common liver malignancy, which has a low
survival rate of all cancers. 5-fluorouracil (5-FU) is clinically recognized to treat HCC. However, the
success of this therapy is highly limited due to rapid clearance and non- selective distribution. Cholesterol-
conjugate (5-FUC) loaded liposomes proposed to facilitate the transport of 5-FUC into tumor cells
via Low-Density Lipoprotein receptor (LDL receptor) that overexpressed in HCC. Thus, the aim of this
study was to use 5-FUC loaded liposome as a promising strategy to combat HCC and improve the response
of HCC to chemotherapy.
Methods:
5-FUC and 5-FU loaded liposomes were optimized based on Cholesterol (CHO) ratio and
type of phospholipid to achieve a potential effect on HCC. Liposomes were prepared by the thin-film
hydration method, and evaluated in terms of particle size, polydispersity, zeta potential, Entrapment
Efficiency (EE), morphology, drug release and cytotoxicity.
Results:
The obtained liposomes had a suitable nano-range particle size with negative zeta potential,
and acceptable EE%. In vitro drug release of 5-FUC loaded liposomes showed a lower cumulative release
over 24 h as compared to 5-FU loaded liposomes. 5-FUC loaded liposomes exhibited a higher in
vitro cytotoxic effect as compared to the free drug and 5-FU loaded liposomes against HepG2 cell lines
after 48 h via MTT assay.
Conclusion:
These results concluded that 5-FUC loaded liposomes could be used as an alternative tactic
to increase the therapeutic index of 5-FU and pave the way for potential clinical applications.

Abstract
The prevalence of liver cancer is increasing over the years and it is the fifth leading cause of mortality worldwide. The intrusive features and burden of low survival rate make it a global health issue in both developing and developed countries. The recommended chemotherapy drugs for patients in the intermediate and advanced stages of various liver cancers yield a low response rate due to the nonspecific nature of drug delivery, thus warranting the search for new therapeutic strategies and potential drug delivery carriers. There are several new drug delivery methods available to ferry the targeted molecules to the specific biological environment. In recent years, the nano assembly of lipoprotein moieties (lipidic nanoparticles) has emerged as a promising and efficiently tailored drug delivery system in liver cancer treatment. This increased precision of nano lipoproteins conjugates in chemotherapeutic targeting offers new avenues for the treatment of liver cancer with high specificity and efficiency. This present review is focused on concisely outlining the knowledge of liver cancer diagnosis, existing treatment strategies, lipoproteins, their preparation, mechanism and their potential application in the treatment of liver cancer.

Abstract
Cell- based targeted delivery is recently gain attention as a promising platform for delivery of anticancer drug in selective and efficient manner. As a new biotechnology platform, bacterial ghosts (BGs) have novel biomedical application as targeted drug delivery system (TDDS). In the current work, Salmonellas' BGs was utilized for the first time as hepatocellular cancer (HCC) in-vitro targeted delivery system. Successful BGs loading and accurate analysis of doxorubicin (DOX) were necessary steps for testing the applicability of DOX loaded BGs in targeting the liver cancer cells. Loading capacity was maximized to reach 27.5 µg/mg (27.5% encapsulation efficiency), by incubation of 10 mg BGs with 1 mg DOX at pH 9 in constant temperature (25 °C) for 10 min. In-vitro release study of DOX loaded BGs showed a sustained release (182 h) obeying Higuchi sustained kinetic release model. The death rate (tested by MTT assay) of HepG2 reached to 64.5% by using of 4 μg/ml, while it was about 51% using the same concentration of the free DOX (P value < 0.0001 One-way ANOVA analysis). The proliferative inhibitory concentration (IC50) of the DOX combined formula was 1.328 µg/ml that was about one third of the IC50 of the free DOX (3.374 μg/ml). Apoptosis analysis (tested by flow-cytometry) showed more accumulation in early apoptosis (8.3%) and late apoptosis/necrosis (91%) by applying 1 μg/ml BGs combined DOX, while 1 μg/ml free DOX showed 33.4% of cells in early apoptosis and 39.3% in late apoptosis/necrosis, (P value˃ 0.05: one-way ANOVA). In conclusion, DOX loaded Salmonellas' BGs are successfully prepared and tested in vivo with promising potential as hepatocellular cancer (HCC) targeted delivery system.

Abstract
The use of bacterial ghosts (BGs) for drug delivery is an extremely fascinating perspective especially with the inherited efficient target-ability to specialized tissues. Trafficking of drug molecules across the outer membrane of Gram-negative bacteria are important to be understood for both loading (influx) and drug release (efflux). In this study, Escherichia coli (E. coli) BGs were prepared using modified protocol sponge-like reduced protocol (SLRP) which was used for loading of doxorubicin (DOX). First time in the literature, different possible factors affecting DOX loading from BGs were examined in this study. These factors including drug concentration, temperature, pH gradient, incubation time and tonicity, are proposed to effect on drug loading into E. coli BGs. Results of optimum effect from accompanied factors were found to be 10 mg/mL as DOX concentration at pH 6 with tonicity of 0.7% incubated overnight at 4 °C. After gather all factors, the amount of DOX loaded inside the BGs was recorded as 37.58%. The in vitro release studies of DOX loaded BGs over time showed a burst initial release rate of 26.75% at the first 12 h followed by a period of sustained release lasting for 16 days to give maximum release rate of 58.04%. Remarkably, DOX loaded in BG showed more apoptosis (55%) than control and DOX solution. Overall, the results indicated the presence of some important factors to be controlled when loading drugs into BGs. Also, data showed the future possibility of utilizing BGs to deliver DOX to colon cancer cells.

Abstract
Abstract
A precise, swift and environmental-friendly reverse phase ultra-high performance liquid chromatographic assay for the determination of thymoquinone (TQ) in plasma samples using thymol (TM) as an internal standard was developed and validated. The method used a high strength silica C18 1.7 μm column (100 × 2.1 mm) with an isocratic mobile phase consisting of a blend of methanol and 20 mM potassium dihydrogen ortho-phosphate (90:10 v/v; pH of 4.2). The selected eluent provided a short run time (≤2 min), better peak symmetry, lower limit of quantification of 10 ng/mL and satisfactory values of other chromatographic parameters including resolution (Rs = 1), capacity factor (k = 21.5 and 14.5 for TQ and TM, respectively), selectivity (α = 1.482) and number of theoretical plates (N = 1653 and 784 for TQ and TM, respectively). The method was efficiently applied to a pharmacokinetic study of TQ following an intraperitoneal administration of 2 mg/kg in mice. The concentrations of TQ in plasma were measurable up to 12 h with Cmax of 404.08 ± 28.91 ng/mL, T1/2 of 2.31 ± 0.10 h and area under plasma concentration-time curve of 1527.00 ± 46.61 ng/mL × h.

Abstract
The solubility values and thermodynamic parameters of a natural phytomedicine/nutrient piperine (PPN) in Transcutol-HP (THP) + water combinations were determined. The mole fraction solubilities (xe) of PPN in THP + water combinations were recorded at T = 298.2-318.2 K and p = 0.1 MPa by the shake flask method. Hansen solubility parameters (HSPs) of PPN, pure THP, pure water and THP + water mixtures free of PPN were also computed. The xe values of PPN were correlated well with "Apelblat, Van't Hoff, Yalkowsky-Roseman, Jouyban-Acree and Jouyban-Acree-Van't Hoff" models with root mean square deviations of < 2.0%. The maximum and minimum xe value of PPN was found in pure THP (9.10 × 10-2 at T = 318.2 K) and pure water (1.03 × 10-5 at T = 298.2 K), respectively. In addition, HSP of PPN was observed more closed with that of pure THP. The thermodynamic parameters of PPN were obtained using the activity coefficient model. The results showed an endothermic dissolution of PPN at m = 0.6-1.0 in comparison to other THP + water combinations studied. In addition, PPN dissolution was recorded as entropy-driven at m = 0.8-1.0 compared with other THP + water mixtures evaluated.

Abstract
Doxorubicin (Dox) is an operational and largely used anticancer drug, used to treat an array of malignancies. Nonetheless, its beneficial use is constrained due to its renal and hepatotoxicity dose dependently. Numerous research findings favor the use of antioxidants may impact Dox-induced liver injury/damage. In the current study, Wistar rats were given naringenin (50 and 100 mg/kg b.wt.) orally for 20 days as prophylactic dose, against the hepatotoxicity induced by single intraperitoneal injection of Dox (20 mg/kg b.wt.). Potency of naringenin against the liver damage caused by Dox was assessed by measuring malonyl aldehyde (MDA) as a by-product of lipid peroxidation, biochemical estimation of antioxidant enzyme system, reactive oxygen species (ROS) level, and inflammatory mediators. Naringenin-attenuated ROS production, ROS-induced lipid peroxidation, and replenished reduced antioxidant armory, namely, catalase (CAT), glutathione reductase (GR), superoxide dismutase (SOD), glutathione peroxidase (GPx), and glutathione (GSH). Naringenin similarly diminished expression of Cox-2 and levels of NF-κB and other inflammatory molecules induced by the Dox treatment. Histology added further evidence to the defensive effects of naringenin on Dox-induced liver damage. The outcomes of the current study reveal that oxidative stress and inflammation are meticulously linked with Dox-triggered damage, and naringenin illustrates the potential effect on Dox-induced hepatotoxicity probably through diminishing the oxidative stress and inflammation.

Abstract
This study was aimed to find out the solubility, thermodynamic behavior, Hansen solubility parameters and molecular interactions of an antiviral drug emtricitabine (ECT) in various “[polyethylene glycol-400 (PEG-400) + water]” mixtures. The solubility of ECT in mole fraction was determined at “T = 298.2 to 318.2 K” and “p = 0.1 MPa” using an isothermal method. The experimental solubilities of ECT in mole fraction were validated and correlated using various computational models which includes “Van’t Hoff, Apelblat, Yalkowsky-Roseman, Jouyban-Acree and Jouyban-Acree-Van’t Hoff models”. All the models performed well in terms of model correlation. The solubility of ECT was increased with the raise in temperature in all “PEG-400 + water” mixtures studied. The highest and lowest solubility values of ECT were found in pure PEG-400 (1.45 × 10−1) at “T = 318.2 K” and pure water (7.95 × 10−3) at “T = 298.2 K”, respectively. The quantitative values of activity coefficients indicated higher interactions at molecular level in ECT and PEG-400 combination compared with ECT and water combination. “Apparent thermodynamic analysis” showed an “endothermic and entropy-driven dissolution” of ECT in all “PEG-400 + water” combinations studied. The solvation nature of ECT was found an “enthalpy-driven” in each “PEG-400 + water” mixture studied.

Abstract
In the present study, we explored SA's activity against DOX-induced cardiotoxicity and revealed its underlying mechanisms. Male Wistar rats (weight, 190-210g; n = 6) were randomly divided into four groups: group I, normal control; group II, DOX 15 mg/kg via intraperitoneal (ip) route; group III, administered DOX+SA 20 mg/kg; and group IV, administered DOX+captopril (CAP 30 mg/kg). SA and CAP were administered orally for seven days, and DOX (15 mg/kg) was injected intraperitoneally an hour before SA treatment on the fifth day. Forty-eight hours after DOX administration, animals were anesthetized and sacrificed for molecular and histology experiments. SA significantly mitigated the myocardial effects of DOX, and following daily administration, it reduced serum levels of lactate dehydrogenase (LDH) and creatine kinase isoenzyme-MB to near normal values. Levels of oxidative stress markers, glutathione-peroxidase, superoxide dismutase, and catalase, in the cardiac tissue were significantly increased, whereas malondialdehyde levels decreased after SA treatment in DOX-administered rats. Furthermore, DOX caused an inflammatory reaction by elevating the levels of proinflammatory cytokines, tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and endothelin- (ET-) 1, as well as nuclear factor kappa-B (NF-κB) expression. Daily administration of SA significantly repressed TNF-α, IL-1β, ET-1, and NF-κB levels. caspase-3 and Bax expression, bcl-2-like protein and caspase-3 activities and levels. Overall, we found that SA could inhibit DOX-induced cardiotoxicity by inhibiting oxidative stress, inflammation, and apoptotic damage.

Abstract
Glipizide (GLZ) is an oral hypoglycemic agent, which is a weakly aqueous soluble drug. The solubility values of GLZ in various neat solvents are scarce in the literature. Hence, the solubility of GLZ in 12 different neat solvents, namely, "water, methanol, ethanol, isopropanol (IPA), 1-butanol, 2-butanol, ethylene glycol (EG), propylene glycol (PG), poly(ethylene glycol)-400 (PEG-400), ethyl acetate (EA), dimethyl sulfoxide (DMSO), and Transcutol-HP (THP)", at "T = 298.2-318.2 K" and "p = 0.1 MPa" was measured. The recorded solubilities of GLZ were correlated by "van't Hoff and Apelblat models" using root-mean-square deviation (RMSD). The overall RMSD was obtained as 1.21 and 1.40% for "Apelblat and van't Hoff models", respectively. Different solubility parameters of all studied materials including drug and solvent were calculated to find the best solvent for GLZ. The solubilities of GLZ (expressed in mole fraction) have been found highest in DMSO (2.81 × 10-2), followed by THP, EA, 2-butanol, 1-butanol, IPA, PEG-400, ethanol, PG, methanol, EG, and water (1.98 × 10-4) at "T = 318.2 K". All investigated solubility parameters of GLZ were recorded very close to the DMSO. "Apparent thermodynamic analysis" showed an "endothermic and entropy-driven dissolution" of GLZ in the 12 different neat solvents. The highest molecular interactions were recorded in GLZ-DMSO compared to other combinations. Overall, DMSO has been considered as the best solvent for the solubilization of GLZ.

Abstract
The current research work was performed to evaluate the solubilization behavior, solution thermodynamics, and solvation behavior of poorly soluble pyridazinone derivative i.e., 6-phenyl-pyridazin-3(2H)-one (PPD) in various binary solvent systems of dimethyl sulfoxide (DMSO) and water using experimental and various computational approaches. The solubility of PPD in various binary solvent system of DMSO and water was investigated within the temperature range T = 298.2 K to 318.2 K at constant air pressure p = 0.1 MPa, by employing an isothermal technique. The generated solubility data of PPD was computationally represented by five different cosolvency models including van't Hoff, Apelblat, Yalkowsky-Roseman, Jouyban-Acree, and Jouyban-Acree-van't Hoff models. The performance of each computational model for correlation studies was illustrated using root mean square deviations (RMSD). The overall RMSD value was obtained <2.0% for each computational model. The maximum solubility of PPD in mole fraction was recorded in neat DMSO (4.67 × 10-1 at T = 318.2 K), whereas the lowest one was obtained in neat water (5.82 × 10-6 at T = 298.2 K). The experimental solubility of PPD in mole fraction in neat DMSO was much higher than its ideal solubility, indicating the potential of DMSO for solubility enhancement of PPD. The computed values of activity coefficients showed maximum molecular interaction in PPD-DMSO compared with PPD-water. Thermodynamic evaluation showed an endothermic and entropy-driven dissolution of PPD in all the mixtures of DMSO and water. Additionally, enthalpy-entropy compensation evaluation indicated an enthalpy-driven mechanism as a driven mechanism for the solvation property of PPD.

Abstract
The current research work proposed the solubility data and solution thermodynamic properties of the cardiovascular agent 6-phenylpyridazin-3(2H)-one [PPD] in twelve pharmaceutical solvents at "T = 298.2 K to 318.2 K" and "p = 0.1 MPa". The measured solubilities of PPD were regressed well with "van't Hoff and Apelblat models". The solid phases of pure and equilibrated PPD were characterized using differential scanning calorimetry and powder X-ray differactometry, and the results suggested no transformation of PPD into solvates/hydrates/polymorphs after equilibrium. The solubilities of PPD in a mole fraction at "T = 318.2 K" were noted at a maximum in dimethyl sulfoxide (DMSO, 4.73 × 10-1), followed by polyethylene glycol-400 (PEG-400, 4.12 × 10-1), Transcutol® (3.46 × 10-1), ethyl acetate (EA, 81 × 10-2), 2-butanol (2.18 × 10-2), 1-butanol (2.11 × 10-2), propylene glycol (PG, 1.50 × 10-2), isopropyl alcohol (IPA, 1.44 × 10-2), ethylene glycol (EG, 1.27 × 10-2), ethanol (8.22 × 10-3), methanol (5.18 × 10-3) and water (1.26 × 10-5). Similar tendencies were also noted at other studied temperatures. The results of the "apparent thermodynamic analysis" showed an endothermic and entropy-driven dissolution of PPD in all pharmaceutical solvents. The results of the activity coefficients suggested a maximum interaction at the molecular level in PPD-DMSO, PPD-PEG-400 and PPD-Transcutol, compared with other combination of the solute and solvents.

Abstract
This work was carried out to determine solubility, solution thermodynamics, solvation behavior, and molecular interactions of a natural compound ferulic acid (FLA) in different '[polyethylene glycol-400 (PEG-400) + water]' binary solvent mixtures at 'T = 298.2 K to 318.2 K' and 'p = 0.1 MPa.' The mole fraction solubilities (xe) of FLA were determined by liquid chromatographic technique using a static equilibrium technique. The obtained solubility data of FLA were regressed using 'Van't Hoff, Apelblat, Yalkowsky-Roseman and Jouyban-Acree models.' The solubility of FLA (expressed in mole fraction) was enhanced with elevation in absolute temperature in each 'PEG-400 + water' binary solvent mixture evaluated. The maximum xe values of FLA were recorded in neat PEG-400 (1.94 × 10-1) at 'T = 318.2 K.' While, the minimum one was obtained in neat water (4.90 × 10-5) at 'T = 298.2 K.' The molecular interactions between FLA-PEG-400 and FLA-water were obtained by determination of activity coefficients of FLA in different 'PEG-400 + water' binary solvent mixtures. The physical data of activity coefficients recorded in this work suggested strong molecular interactions in FLA-PEG-400 in comparison with FLA-water. 'Apparent thermodynamic analysis' suggested an 'endothermic and entropy-driven dissolution' of FLA in each 'PEG-400 + water' binary solvent mixture investigated.

Abstract
This study was conducted to formulate, characterize, and investigate the bioavailability of hydrocortisone (HCT) when prepared as solid dispersions. HCT was mixed in an organic solvent with polyethylene glycol 4000 (PEG 4000) and Kolliphor® P 407. Spray drying technique was employed to form a solid dispersion formulation at a specific ratio. Physical and chemical characterization of the formed particles were achieved using differential scanning calorimetry, scanning electron microscopy, Fourier transform infrared spectroscopy, and powder X-ray diffractometry. Furthermore, comparative in vitro and in vivo studies were conducted between the formulated particles against neat HCT. The formulated solid dispersion showed elongated particles with leaf-like structure. Formation of new chemical bonds in the formed particle was suggested due to the change in the vibrational wave numbers and the significant improvement in the bioavailability of the dispersed particles proved the importance of this technique.

Abstract
Bacterial ghosts (BGs) are non-deformed bacterial cell envelopes that possess undamaged external configurations for precise attachment to different cells of the human body. The Escherichia coli BGs were successfully produced using a modified sponge-like reduced protocol and characterized by SEM. Four different concentrations of 5-fluorouracil (5-FU) were used to study the impact on the "ghosts" cell wall. 5-FU was then loaded into the BGs and the loading capacity (LC %) and entrapment efficiency (EE %) were determined and were found to be 38.3 ± 0.8 and 76.6 ± 0.8, respectively. The in vitro release studies were conducted in dialysis bags over a time period of 16 days and the accumulative 5-FU released (%) was calculated. Overall, 69.2% of the ghost-associated 5-FU was released from the BGs and release from the E. coli ghosts is governed by non-Fickian diffusion. The Caco-2 cell line was used to investigate the cytotoxicity of 5-FU-loaded BGs.

Abstract
Abstract
The purpose of this study was to formulate and validate a new green high-performance liquid chromatography-ultraviolet (HPLC)-UV method for quick quantification of rosuvastatin calcium (ROC) in standard drugs. The results showed a combination of ethanol:methanol:ethyl acetate (6:3:1 v/v) at a rate of 1.0 ml/min to be the best for identifying ROC and its separation from its breakdown products. The identification of ROC was achieved using a NUCLEODUR 150 mm×4.6 mm RP C8 column packed using 5 μm filler as the stationary phase and detection was performed at 254 nm. The technique developed was checked for linearity, selectivity, accuracy, precision, robustness and sensitivity as well as specificity. The usefulness of the proposed process was confirmed by analyzing ROC in a prepared self-nanoemulsifying drug delivery system (SNEDDS) and over-the-counter products. The amount of ROC in SNEDDS was found to be 98.38%. The HPLC-UV system we developed effectively determined the ROC peak along with its breakdown products which confirmed the stability-indicating property of the projected system. The system could also be used to compare the solubility of rosuvastatin nanoparticles in standard drugs. These outcomes indicated that the developed HPLC could be effectively used for the regular investigation of ROC in standard drugs, various pharmaceutical formulations and drug release samples.

Abstract
OBJECTIVE The solubility of an herbal compound ferulic acid (FA) in various (isopropanol (IPA) + water) mixtures was measured and correlated at temperatures 'T = 298.2 K to 318.2 K' and pressure 'p = 0.1 MPa'. METHODS The experimental solubilities of FA in mole fraction were determined using a static equilibrium method and correlated with 'Apelblat, Van't Hoff, Yalkowsky and Jouyban-Acree models'. KEY FINDINGS The maximum mole fraction solubilities of FA were obtained in neat IPA (2.58 × 10-2 at T = 318.2 K) followed by minimum in neat water (4.87 × 10-5 at T = 298.2 K). The activity coefficients of FA in various (IPA + water) mixtures were determined to evaluate the molecular interactions between FA and co solvent mixtures. Strong molecular interactions were seen between FA and neat IPA in comparison with FA and neat water. 'Apparent thermodynamic analysis' indicated an 'endothermic and entropy-driven dissolution' of FA in all (IPA + water) mixtures evaluated. CONCLUSIONS Isopropanol was investigated as a good cosolvent in the solubility enhancement of FA in water; therefore, it could be used as solubilizer in solubility enhancement and formulation development of FA.
