Abstract
In the last few decades, green analytical chemistry (GAC) has become a smart magical solution for the qualification and quantification of many drugs. In the current study, a direct, sensitive, and green RP-HPLC method was used to separate three anti-histaminic combinations rupatadine/montelukast, desloratadine/montelukast, fexofenadine/montelukast, and finally a mixture of rupatadine and its metabolite; desloratadine in less than 20 min. The developed method was optimized by a 23 full factorial design to improve the chromatographic responses. The proposed method was used to analyze these antihistaminic combinations at different pharmaceutical ratios. The linearity range is from 1 to 10 µg/mL for rupatadine, desloratadine, and montelukast, while for fexofenadine from 1 to 24 µg/mL drugs. The proposed method is useful in common quality control analysis of the investigated quaternary combinations because of its non-toxic and eco-friendly effects on the environment and human beings. The proposed procedure was thoroughly validated in accordance with ICH guidelines and was revealed to be accurate, reproducible, and selective. The developed methods were compared with a reported reference comparison method, where no significant difference was observed.

Abstract
For the simultaneous estimation of two co-formulated antihistaminic drugs (Bilastine and Montelukast), a novel and eco-friendly reversed-phase HPLC approach with both diode array and fluorescence detection modes was designed. Rather than using the routine methodology, the Quality by Design (QbD) approach was adopted to speed up the method development and to test robustness of the method. To evaluate the effect of variable factors on chromatographic response, a full factorial design was used. The chromatographic separation was performed using isocratic elution on the C18 column. The mobile phase consists of 92% methanol, 6% acetonitrile, and 2% phosphate buffer with 0.1 (v/v) triethylamine adjusted to pH 3, it was pumped at a flow rate of 0.8 mL/min with an injection volume of 20 μL. The developed stability indicating HPLC approach was used to assess the stability of montelukast (MNT). It was subjected to a variety of stress conditions, including hydrolytic (acid-base), oxidative, thermal, and photolytic stress conditions. All of these conditions were found to have relevant degradation pathways. Under the described experimental conditions, MNT degradation followed pseudo-first-order kinetics. The kinetic parameters of its degradation (rate constant and t1/2) were calculated and a proposal for the degradation pathway was postulated.

Abstract
This study was proposed to develop an optimized sertraline hydrochloride (SER)-loaded bilosomal system and evaluate its potential for enhancement of drug oral bioavailability. A full 23 factorial design was used to prepare SER-loaded bilosomal dispersions by thin film hydration using span 60, cholesterol (CHL), and sodium deoxycholate (SDC). The investigated factors included the total concentration of span 60 and CHL (X1), span 60:CHL molar ratio (X2), and SER:SDC molar ratio (X3). The studied responses were entrapment efficiency (EE%) (Y1), zeta potential (Y2), particle size (Y3), and in vitro % drug released at 2 (Y4), 8 (Y5), and 24 h (Y6). The selected optimal bilosomal dispersion (N1) composition was 0.5% w/v (X1), 1:1 (X2), and 1:2 (X3). Then, N1 was freeze dried into FDN1 that compared with pure SER for in vitro drug release, ex vivo permeation through rabbit intestine, and in vivo absorption in rats. Moreover, storage effect on FDN1 over 3 months was assessed. The optimal dispersion (N1) showed 68 ± 0.7% entrapment efficiency, - 41 ± 0.78 mV zeta potential, and 377 ± 19 nm particle size. The freeze-dried form (FDN1) showed less % drug released in simulated gastric fluids with remarkable sustained SER release up to 24 h compared to pure SER. Moreover, FDN1 showed good stability, fivefold enhancement in SER permeation through rabbit intestine, and 222% bioavailability enhancement in rats' in vivo absorption study compared to pure SER. The SER-loaded bilosomal system (FDN1) could improve SER oral bioavailability with minimization of gastrointestinal side effects.

Abstract
Dapoxetine HCl is used for the treatment of premature ejaculation. Dapoxetine is primarily metabolized in the liver and kidney and its metabolites are inactive; resulting in reduced bioavailability. Also, one of the commonly encountered issues in the oral dapoxetine formulae is its bitter taste. Thus, the objective of this study was to develop and to optimize novel dapoxetine taste-masked oral thin films (OTFs), to offer a faster dissolution rate, rapid release pattern, lower liver metabolism, and better patient compliance. To achieve our goal, the applicability of either pullulan or maltodextrin as strip forming polymers were investigated in the preparation of (OTFs), while glycerol was used as a plasticizer. Also, the physicochemical characteristics of dapoxetine in a resinate complex with AmberLiteTM -IRP69 as taste masking were evaluated. Furthermore, a 23 factorial design was used to study and to optimize the effect of the independent variables (strip forming polymer (X1), glycerol (X2) and AmberLiteTM (X3) amounts) on the disintegration time (Y1), degree of elongation (Y2), and degree of in vitro drug release in phosphate buffer pH 6.8 at 5 minutes (Q5min, Y3) as responses. P2 batch (OTF) (pullulan 96 mg, glycerol 12 mg, AmberLiteTM 32 mg, and dapoxetine 30 mg) was identified as an optimized formulation showing an in vitro disintegration time 9.33 s, 35.56% elongation, and 91.43% Q5min; excellent in vivo disintegration time; good overall taste acceptability and stable resinate complex.

Abstract
A 23 full factorial design model was used for the development of a new high performance liquid chromatography method with UV detection to estimate three antifungal drugs simultaneously. Fluconazole (FLU), itraconazole (ITR) and terbinafine (TRH) are co-administered for severe fungal infections. They have been determined using MOS-1 Hypersil C18 column and an isocratic eluent; methanol 95% and phosphate buffer 5% with 0.001% triethylamine. The pH was adjusted to 7, and the flow rate was 0.7 ml min-1. The three drugs were separated within less than 7 min at 210 nm. The developed method gave a linear response over 5-80 µg ml-1, 5-50 µg ml-1 and 1-50 µg ml-1 for FLU, ITR and TRH, respectively. It showed detection limits of 0.88, 0.29 and 0.20 µg ml-1 and quantification limits of 2.66, 0.88 and 0.60 µg ml-1 for the three drugs, respectively. The design of the experiment facilitated the optimization of different variables affecting the separation of the three drugs. The sensitivity of the designed method permitted the simultaneous estimation of ITR and TRH in spiked human plasma successfully.

Abstract
Oral drug administration provided as solid oral dosage forms (SODF) remains the major route of drug therapy in primary and secondary care. There is clear evidence for a growing number of clinically relevant swallowing issues (e.g., dysphagia) in the older patient population, especially when considering the multimorbid, frail, and polymedicated patients. Swallowing impairments have a negative impact on SODF administration, which leads to poor adherence and inappropriate alterations (e.g., crushing, splitting). Different strategies have been proposed over the years in order to enhance the swallowing experience with SODF, by using conventional administration techniques or applying swallowing aids and devices. Nevertheless, new formulation designs must be considered by implementing a patient centric approach in order to efficiently improve SODF administration by older patient populations. Together with appropriate SODF size reductions, innovative film coating materials that can be applied to SODF and provide swallowing safety and efficacy with little effort being required by the patients are still needed. With that in mind, a literature review was conducted in order to identify the availability of patient centric coating materials claiming to shorten esophageal transit times and improve the overall SODF swallowing experience for older patients. The majority of coating technologies were identified in patent applications, and they mainly included well-known water soluble polymers that are commonly applied into pharmaceutical coatings. Nevertheless, scientific evidence demonstrating the benefits of given SODF coating materials in the concerned patient populations are still very limited. Consequently, the availability for safe, effective, and clinically proven solutions to address the increasing prevalence of swallowing issues in the older patient population is still limited.

Abstract
The severity of tuberculosis (TB) in children is considered a global crisis compounded by the scarcity of pharmaceutical formulations suitable for pediatric use. The purpose of this study was to optimally develop and evaluate a pyrazinamide containing edible orodispersible film formulation potentially suitable for use in pediatrics actively infected with TB. The formulation was prepared employing aqueous-particulate blending and solvent casting methods facilitated by a high performance Box Behnken experimental design template. The optimized orodispersible formulation was mechanically robust, flexible, easy to handle, exhibited rapid disintegration with initial matrix collapse occurring under 60 s (0.58 ± 0.05 min ≡ 34.98 ± 3.00 s) and pyrazinamide release was controlled by anomalous diffusion coupled with matrix disintegration and erosion mechanisms. It was microporous in nature, light weight (57.5 ± 0.5 mg) with an average diameter of 10.5 mm and uniformly distributed pyrazinamide load of 101.13 ± 2.03 %w/w. The formulation was physicochemically stable with no evidence of destructive drug–excipient interactions founded on outcomes of characterization and environmental stability investigations. Preliminary inquiries revealed that the orodispersible formulation was cytobiocompatible, palatable and remained intact under specific storage conditions. Summarily, an edible pyrazinamide containing orodispersible film formulation was optimally designed to potentially improve TB pharmacotherapy in children, particularly the under 5 year olds.

Abstract
The aim of this study was to prepare orally disintegrating tablets (ODTs) containing dexamethasone (DEX) by direct compression method with sufficient hardness and rapid disintegration time. In order to save time, money, and human resources in designing and improvement of formulation, the statistical software Design Expert is used. Box-Behnken response surface methodology was applied to evaluate and optimize the effects of concentrations of three excipients, Kollidon CL-SF (X1), Pearlitol SD200 (X2), and Prosolv SMCC (X3) as independent factors on four responses: percentage of drug released after 5 min, disintegrating time, hardness, and friability. Thirteen formulations offered by the Box-Behnken design were prepared by direct compression method and ultimate weight of 200 mg, while the amount of DEX was 4 mg. All formulations were characterized for parameters such as diameter, hardness, weight, thickness, friability, and disintegration time. Following the statistical results, the effects of independent variables on responses were evaluated and the optimum formulation regarding acceptable responses consisted of 15% Kollidon, 39.66% Pearlitol, and 7.5% Prosolv which showed 95.28% release of the drug after 5 min, disintegrating time of 30 sec, 6.1 kg hardness, and 0.12% of friability with an acceptable taste as the optimized formulation.

Abstract
Purpose: Cocrystallisation of drug with coformers is a promising approach to alter the solid sate properties of drug substances like solubility and dissolution. The objective of the present work was to prepare, formulate and evaluate the piroxicam cocrystal by screening various coformers. Methods: Cocrystals of piroxicam were prepared by dry grinding method. The melting point and solubility of crystalline phase was determined. The potential cocrystal was characterized by DSC, IR, XRPD. Other pharmaceutical properties like solubility and dissolution rate were also evaluated. Orodispersible tablets of piroxicam cocrystal were formulated, optimized and evaluated using 32 factorial design. Results: Cocrystals of piroxicam-sodium acetate revealed the variation in melting points and solubility. The cocrystals were obtained in 1:1 ratio with sodium acetate. The analysis of Infrared explicitly indicated the shifting of characteristic bands of piroxicam. The X-Ray Powder Diffraction pattern denoted the crystallinity of cocrystals and noteworthy difference in 2θ value of intense peaks. Differential scanning calorimetry spectra of cocrystals indicated altered endotherms corresponding to melting point. The pH solubility profile of piroxicam showed sigmoidal curve, which authenticated the pKa-dependent solubility. Piroxicam cocrystals also exhibited a similar pH-solubility profile. The cocrystals exhibited faster dissolution rate owing to cocrystallization as evident from 30% increase in the extent of dissolution. The orodispersible tablets of piroxicam cocrystals were successfully prepared by direct compression method using crosscarmelose sodium as superdisintegrant with improved disintegration time (30 sec) and dissolution rate. Conclusion: The piroxicam cocrystal with modified properties was prepared with sodium acetate and formulated as orodispersible tablets having faster disintegration and greater dissolution rate.

Abstract
PURPOSE Preparation of Isoniazid (INH) loaded nanogel particles using gamma radiation as safe, simple, cheap and reproducible technique for promoting mycobacterial killing in a lower-dose system aiming in developing of drug resistance. METHODS Polymeric pH-sensitive nanogels were prepared by gamma radiation-induced polymerization of Acrylic acid (AAc) or Itaconic acid (IA), in aqueous solution of polyvinylpyrrolidone (PVP), as template polymer. The prepared nanogels were utilized for encapsulation of INH. 31X22 factorial design was employed for optimization and exploring the effect of radiation dose (X1) (30-50kGy), ratio of PVP: acid (X2) (50:50-30:70) and type of acid (X3) on the prepared nanogel characterization RESULTS: The optimized levels of X1, X2 and X3 were (50 KGy, 30:70 and Itaconic acid, respectively), with a desirability of 0.959. In-vitro INH release rate from the prepared nanogels decreased with increasing gamma radiation doses, with the predominance of the diffusion mechanism for drug release pattern. In addition, it was perceived that the minimum inhibitory concentration (MIC) of INH loaded PVP/PIA nanogels on Mycobacteria Tuberculosis was 8 folds lower than that of INH solution. CONCLUSION The prospective of PVP-K90/PIA was recommended as a smart candidate for delivery of INH with promising achievements against tuberculosis than free drug.

Abstract
The aim of this study was to develop a novel double-layer bi-medicated prolonged release mucoadhesive buccal film (MBF) containing lidocaine hydrochloride (LC) and diclofenac potassium (DK). The ultimate goal of the prepared system is the treatment of radiation-induced oral mucositis pain with improved patient acceptance. MBFs were prepared using 3 × 22 randomized full factorial design for film optimization. Nanoemulsion system (NES) was used to mask DK bitter taste. The prepared films were characterized, viz thickness, mass uniformity, surface pH, folding endurance, swelling studies, ex vivo bioadhesive strength, in vitro drug release, and ex vivo permeation. The in vivo evaluation was carried out by testing the anti-inflammatory and analgesic activities on rats followed by a clinical study on patients to prove their acceptance. The optimized MBF composed of 10% w/w HPMC-4KM, 50 mg LC, and 50 mg DK-NES was selected due to prolonged in vitro drug release pattern and ex vivo permeability (95.24 ± 2.14 and 93.48 ± 3.24% in 6 h, respectively). MBF exposed a strong anti-inflammatory effect from 61 to 87% inhibition with a strong analgesic effect when compared to DK® and LC®, respectively. The clinical study revealed that films were accepted by the patients, and the presence of LC on the outer side helped in pain feeling reduction while DK-NES in the inner side facilitated in rapidly relieving the inflammation effect.

Abstract
PURPOSE The design of pediatric formulations is challenging. Solid dosage forms for children have to meet the needs of different ages, e.g. high number of dosing increments and strengths. A modular formulation strategy offering the possibility of rapid prototyping was applied. Different tablet compositions and the resulting tablet characteristics were investigated for dispersible tablets using customized analytical methods. METHODS Fluid bed granules were blended with extragranular components, and compressed to tablets. Disintegration behavior was studied with a Texture Analyzer and a Tensiometer. RESULTS Methods for determination of disintegration time and water uptake of tablets were developed with a Texture Analyzer, and a Tensiometer, respectively. Twenty-two different tablet formulations were prepared and analyzed with respect to disintegration time, hardness, friability, and viscosity. Multivariate data analysis revealed a high impact of type and amount of viscosity enhancer on the disintegration behavior of tablets. An optimized formulation was selected with a disintegration time of 24 s. CONCLUSION Methods providing additional information on the disintegration behavior of dispersible tablets compared to standard pharmacopoeia methods were established. Selecting the right type and level of viscosity enhancer and superdisintegrant was critical for developing pediatric tablets with a disintegration time of less than 30 s but still pleasant mouth feel.

Abstract
The present study deals with the formulation optimization of sodium carboxymethyl cellulose-alginate mucoadhesive beads containing probiotic Lactobacillus sporogenes through ionotropic gelation using 32 factorial design. The effect of sodium carboxymethyl cellulose-alginate concentration on the probiotic entrapment efficiency (PEE, %), viability in simulated gastric fluid (log CFU/g), and mucoadhesion over 8 hr (%) was optimized. The optimized beads containing probiotic Lactobacillus sporogenes showed entrapment efficiency of 93.7±1.97%, viability of probiotic in simulated gastric fluid (log CFU/g) of 9.34, mucoadhesion of 71.75±1.38%, and mean diameter of 1.21±0.11 mm. The beads were also characterized by SEM, FTIR, and XRD. The swelling and degradation of these beads were influenced by pH of the test medium. Finally, stability tests performed at room temperature (25~28°C) highlighted a bacterial viability of about 91% and 86% after 1 and 2 months, respectively. The advantageous properties of probiotic Lactobacillus sporogenes-loaded mucoadhesive beads make them suitable for incorporation in functional food and/or pharmaceutical products.

Abstract
High performance liquid chromatographic method was optimized, developed and validated as per the ICH guidelines. In this study the 20 mM ammonium formate and acetonitrile in the 57:43 ratio were used as mobile phase for the analysis of valsartan. Full factorial design was used to optimize the effect of variable factors. The responses were peak area, tailing factor and number of theoretical plates. The quadratic effect of flow rate and wavelength individually as well as in interaction were most significant (p < 0.0001 and p < 0.0086, respectively) on peak area; the quadratic effect of pH of buffer was also most significant effect (p < 0.0001) on tailing factor (5%) whereas the quadratic effect of flow rate and wavelength individually was significant (p = 0.0006 and p = 0.0265, respectively) on the number of theoretical plates. The high-performance liquid chromatographic separation was performed at the flow rate 1.0 min/mL, UV detector wavelength 250 nm and pH of the buffer 3.0 as optimized parameters using design of experiments. The retention time values of valsartan were found to be 10.177 min. Percent recovery in terms of accuracy for the prepared valsartan nanoparticles was found in the range of 98.57–100.27%.

Abstract
Introduction: Epilepsy is a serious neurological disorder. Lamotrigine is an alternative to lithium for the treatment of epilepsy, and its oral bioavailability is 98%; however, its poor aqueous solubility hinders its oral absorption. Among the techniques available to enhance the solubility, dissolution rate and bio availability of poorly soluble drugs, liqui-solid technique is a novel and promising approach. The objectives of the investigation are to formulate, optimize lamotrigine liqui-solid compacts using 23 factorial experiments, validate experimental designs statistically and to compare with the marketed tablets using similarity and difference factors. Materials and Methods: Based on solubility studies tween 20 as nonvolatile liquid, avicel pH 101 as a carrier and aerosil 200 as a coating material were used. Liquid load factor other flow and compression characteristics were determined for different ratios of carrier and coat materials. Suitable quantities of carrier and coat materials were taken, according to the experimental designs other excipients were added, liqui-solid tablets were prepared by direct compression and evaluated. Drug excipient compatibility was determined using Fourier transform infrared spectroscopy (FTIR) analysis. The hardness, disintegration time and T75% were considered for validation of experimental designs. Results: The physicochemical properties of tablets such as hardness (1.5 ± 0.8–4.95 ± 0.96 kg), in vitro disintegration time (40 ± 20–320 ± 25 s) and Friability (0.39 ± 0.5–1.45 ± 0.2% also <1%) possess all the Indian pharmacopoeal requirements. The T75% was calculated and found to be 6.62–22.8 min. The rate of drug release followed first order kinetics. f1 and f2 values indicated the similarity in dissolution profiles between marketed and the optimized formulation and 63.64% similar with that of the marketed fast disintegrating tablets. FTIR studies revealed the absence of drug excipient incompatibility.

Abstract
Fast disintegrating tablets (FDTs) have received ever-increasing demand during the last decade, and the field has become a rapidly growing area in the pharmaceutical industry. Oral drug delivery remains the preferred route for administration of various drugs. Recent developments in the technology have prompted scientists to develop FDTs with improved patient compliance and convenience. Upon introduction into the mouth, these tablets dissolve or disintegrate in the mouth in the absence of additional water for easy administration of active pharmaceutical ingredients. The popularity and usefulness of the formulation resulted in development of several FDT technologies. FDTs are solid unit dosage forms, which disintegrate or dissolve rapidly in the mouth without chewing and water. FDTs or orally disintegrating tablets provide an advantage particularly for pediatric and geriatric populations who have difficulty in swallowing conventional tablets and capsules. This review describes various formulations and technologies developed to achieve fast dissolution/dispersion of tablets in the oral cavity. In particular, this review describes in detail FDT technologies based on lyophilization, molding, sublimation, and compaction, as well as approaches to enhancing the FDT properties, such as spray drying and use of disintegrants. In addition, taste-masking technologies, experimental measurements of disintegration times, and dissolution are also discussed.

Abstract
INTRODUCTION Due to a lack of approved drugs and formulations, children represent the most vulnerable patients. Magistral, unlicensed formulations obtained by the manipulation of solid forms should undergo clinical evaluation to ensure bioequivalence. The development of new pediatric medicines is complex and faces technological, economic and ethical challenges. This phenomenon has contributed to the emergence of an adult-children gap. To improve the situation, the World Health Organization launched the global campaign 'Make medicines child size' and a number of international initiatives have been established. The situation is more critical in the case of poverty-related diseases (PRDs) that mainly affect poor countries. AREAS COVERED This review critically discusses different strategies to develop pediatric formulations and drug delivery systems (DDS) in PRDs and their potential implementation in the current market. Readers will gain an updated perspective on the development of pediatric medicines for the treatment of PRDs and the proximate challenges and opportunities faced to ensure an effective pharmacotherapy. EXPERT OPINION There is an urgent need for the development of innovative, scalable and cost-viable formulations to ensure pediatric patients have access to appropriate medications for PRDs. The guidelines of the International Conference on Harmonisation constitute a very good orientation tool, as they emphasize physiological and developmental aspects that need to be considered in pediatric research. It is important to consider cultural, economic and ethical aspects that make developing nations facing PRDs different from the developed world. Thus, the best strategy would probably be to conceive and engage similar initiatives in the developing world, to address unattended therapeutic niches.

Abstract
Several matrix tablet formulations (hydrophilic-based, wax-based, and three-layer tablets) were designed for controlling the release of the highly water soluble drug, venlafaxine hydrochloride (VenHCl) for once-daily administration. The three-layer tablets consist of non-swellable, compritol-based middle layers containing the drug to which hydrophilic top and bottom barrier layers were applied. A 2(3) full-factorial design was employed for optimization and to explore the effect of different variables on the release rate of the drug from the three-layer tablets. The optimized levels of each independent variable were based on the criterion of desirability. The calculated values of f(1) and f(2) were 4.131 and 79.356, respectively; indicating that the release profile of the optimized PEO layered tablet formulation is comparable to that of the target release model. The pharmacokinetic parameters of VenHCl from the optimized three-layer tablet was compared to the marketed extended release capsule as a reference in healthy human subjects using a randomized crossover design. In this study, the 90% confidence interval for AUC(0-24) and AUC(0-∞) are within (0.8-1.25), which satisfied the bioequivalence criteria. It could be concluded that a promising once-daily extended-release three-layer tablet of the highly water soluble drug, VenHCl, was successfully designed.
