In absence of effective therapy to manage COVID-19, repurposed therapies were being used to manage the condition. In view of an urgent need for definitive therapy, multiple repurposed drugs, and investigational drug candidates are being tried in clinical trials which may lead to the emergence of unknown short term and long term adverse drug reactions (ADRs), and hence it is crucial to assess the safety of the tried therapeutic interventions. The lag in the pharmacovigilance activities in the midst of this pandemic fosters under-reporting of ADRs. Difficulty in causality assessment due to factors like wide variations in clinical presentation, concomitant use of multiple drugs, associated comorbidities, drug-drug and drug-disease interaction which forestalls the appropriate causality assessment. Hydroxychloroquine, a repurposed antimalarial drug has been a part of hue and cry at present because of its in-question safety in patients with cardiac disorders. National and International Drug monitoring centers have stressed upon reporting of ADRs and to boost up the process and come up with various recommendations. We can overcome these issues by working cohesively, motivating HCPs and patients to report ADRs electronically, and by setting up dedicated pharmacovigilance rapid response team to tackle the issues at the earliest.</p> 2021-05-07T00:00:00+0530 Copyright (c) 2021 Siddhartha Dutta, Sneha Ambwani, Govind Mishra, Hina Lal, Kishna Ram, Tarun Kumar https://innovareacademics.in/journals/index.php/ijap/article/view/39369 GASTRORETENTIVE FLOATING TECHNOLOGY FOR ERADICATION OF HELICOBACTER PYLORI: AN INSIGHT VIEW 2021-05-10T10:42:23+0530 RAKESH PAHWA rakesh_pahwa2407@yahoo.co.in BIGUL YOGESHVER BHARDWAJ bybraw08@gmail.com ARCHANA SHARMA archanakuk@gmail.com MONA PIPLANI mona_piplani13@rediffmail.com MANISH KUMAR manish_singh17@rediffmail.com <p><em>Helicobacter pylori </em>is a virulent human pathogen infecting about 50% of the population worldwide. Being a leading cause of gastric ulcer, duodenal ulcer, gastritis, dyspepsia, gastric tumorigenesis etc., this organism has been the focus of concerted study to establish uncertainty of its genetics, immunopathogenesis and cell biology. Scientists have tried to effectively eradicate this pathogen from the gastrointestinal tract in various manners. Inquest of this venture, gastroretentive drug delivery systems including floating dosage forms have emerged as a boon and offer significantly improved therapeutic effects of different antimicrobial drugs. This article presents an evocative review of the structural features, epidemiological evidences and various pharmacotherapeutics vistas. In addition, various novel gastroretentive dosage forms developed so far to combat <em>Helicobacter pylori</em> infection are also discussed. Comprehensive literature review has been performed for this manuscript by utilizing relevant databases like PubMed, SCOPUS, Web of Science, Science Direct, Google Scholar etc., from 1997 up to the year 2020.</p> 2021-05-07T00:00:00+0530 Copyright (c) 2021 Rakesh Pahwa, Bigul Yogeshver Bhardwaj, Archana Sharma , Mona Piplani , Manish Kumar https://innovareacademics.in/journals/index.php/ijap/article/view/40890 FUNDAMENTAL ASPECTS OF A THIRD COMPONENT USED IN TERNARY SOLID DISPERSION: A REVIEW 2021-05-10T13:46:15+0530 SREE VARSHINI S. varsha291296@gmail.com VAIYANA RAJESH C. rajeshresort@gmail.com <p>Ternary solid dispersion (TSD) is one of the promising approaches used in recent studies to address the issues encountered by poorly water-soluble drugs. The binary solid dispersion (BSD) with the drug and the single polymer is not sufficient to satisfy all the criteria such as improved solubility, dissolution, stability, supersaturation, and recrystallization inhibition. Hence, the TSD with the third component/ternary agent aids in overcoming the limitations, thereby enhancing the solubility and bioavailability to a greater extent when compared to the BSD. Excipients that can be used as a third component includes surfactants, pH modulator, polymer and adsorbents. All these excipients have distinct benefits in improving the efficiency of the final dosage form. However, care must be taken in selecting suitable excipients for the research. This review highlights the impact of these excipients in improving the formulation complications and the therapeutic potential of the TSD.</p> 2021-05-07T00:00:00+0530 Copyright (c) 2021 sreevarshini, VAIYANA RAJESH C https://innovareacademics.in/journals/index.php/ijap/article/view/40865 STATE-OF-THE-ART NANOTECHNOLOGY BASED DRUG DELIVERY STRATEGIES TO COMBAT COVID-19 2021-05-11T12:17:18+0530 SHARON K.

NAIR sreejacnair@aims.amrita.edu <p>The emerging Coronavirus Disease-19 (COVID-19) pandemic has had a global impact on all important aspects of our society. As it is known, SARS-Cov-2 can withstand up to 72 h in adverse environmental conditions, which can aid its rapid spread. Woefully, an efficacious and approbated vaccine for the SARS-CoV-2 virus remains unavailable, which makes the problem more frightening and presently more complicated bestowing forlorn medical care. Nevertheless, global clinical research is studying several over-the-counter (OTC) drugs approved for other indications to confront coronavirus. Over the past decade, therapeutic nanoparticles have been regarded as a felicitous tool for the efficient and persnickety delivery of therapeutic groups (i.e., drugs, vaccines, siRNAs, and peptides) to the site of infection. They can adequately convey the drug encapsulated nanoparticle to a designated locus without instigating unsought effects. Besides, they acquiesce the use of non-invasive imaging methods to monitor the surface of the infection and the response to treatment. The formulated nanoparticle is apposite for intranasal drug delivery which is a meritorious method to deliver therapeutic moiety for viral diseases affecting the lungs. Applying nanoparticles via intranasal route surmounted several demerits of mucosal administration like circumventing enzymatic degradation of the therapeutic moiety, upgrading and prolonging the action of the drug, etc., and can thus corroborate as an exceptional strategy to encounter respiratory viruses like coronavirus. In this article, we illuminate the promising role of nanoparticles as effective carriers of therapeutic or immunomodulatory agents to help combat COVID-19.</p> <p>The search criteria used were Pubmed, Medscape, Google scholar, etc and the keywords are coronavirus, nanoformulations, nanoparticles, drug delivery, intranasal delivery, etc. The articles range from 2012 to 2020.</p> 2021-05-07T00:00:00+0530 Copyright (c) 2021 Sharon K Joseph, Arya M A, Sachin Thomas, sreeja c nair https://innovareacademics.in/journals/index.php/ijap/article/view/40863 A COMPREHENSIVE REVIEW ON PHARMACEUTICAL AND NUTRITIONAL APPLICATIONS OF INULIN 2021-05-10T13:29:26+0530 C.

KULKARNI pkkulkarni@jssuni.edu.in <p>Inulin is a versatile, water-soluble polysaccharide that is commonly available in nature. In the pharmaceutical industry, the non-digestible function of inulin has made it attractive. Inulin is granted with GRAS status by the FDA and more than 30,000 plants in nature store inulin as a carbohydrate. The chicory is the key plant source of inulin out of all sources. It can be used as the sugar or fat replacer in the processed foods to influence the desirable characteristics. Good biocompatibility, essential chemical properties, and a wide variety of bioactivities have rendered inulin an outstanding natural nutrient. Regulating blood sugar, antioxidant, anticancer is some of the biological activities of inulin. Inulin can also be a carrier for colon/tumor targeting, as only specific enzymes in the colon zhydrolyze the inulin. It allows the growth of micro-flora, the good bacteria in the gut. Inulin is considered as a prebiotic as it is fermented by bacteria that normalize the colon. This review offers an in-depth insight into its novel Pharmaceutical applications as well as sources, processing, physicochemical properties, and nutritional and physiological activities. The chemically modified inulin is gaining a specific interest in the pharmaceutical field with its outstanding properties which are discussed in this review.</p> 2021-05-07T00:00:00+0530 Copyright (c) 2021 PK Kulkarni Kulkarni, C.

Improving the permeability of these barriers would enhance the disease's clinical prognosis and promote patients' quality of life. To this end, scientists have conducted several studies to determine the most suitable route for CNS delivery. Most of which show that the nose-to-brain is proposed to be the most convenient, efficacious and clinically beneficial non-invasive means of delivering chemotherapeutic agents directly to the brain. Therefore, this study compares the therapeutic benefits of intranasal and other conventional brain delivery systems and&nbsp;further evaluates the clinical benefits of using different nanocarriers for brain tumour targeting. However, we surveyed the literature by conducting an in-depth search of the research keywords and their combinations in&nbsp;recognized&nbsp;scientific databases, primarily Science Direct, PubMed, Google Scholar, and Research Gate. Our findings have shown that the nose-to-brain delivery of chemotherapeutics is a breakthrough in bypassing the effects of BBB, BTB, and CSF barriers, improving the delivery of drugs to the brain for specific tumour targeting with desired clinical prognosis.</p> 2021-05-07T00:00:00+0530 Copyright (c) 2021 Ibrahim Aminu Shehu Aminu Shehu, Vijender Singh Mahalwal https://innovareacademics.in/journals/index.php/ijap/article/view/40994 RISE AND FALL IN SARS-COV-2 GLOBAL PANDEMIC STRAIN RATE–AN OVERVIEW 2021-05-11T13:10:29+0530 ABDULLAH ANWA a.anwar14330@gmail.com VISHAL SINGH CHANDEL a.anwar14330@gmail.com SATYENDRA PRATAP SINGH a.anwar14330@gmail.com SATYA PRAKASH SINGH a.anwar14330@gmail.com NEDA ANWAR a.anwar14330@gmail.com <p>After its discovery in Hubei in China in December 2019, the deadly rise of modern coronavirus (COVID-19 or 2019-nCoV) has spread globally. SARS-CoV-2 disease COVID-19 has quickly spread worldwide, posing a serious threat to health and the economy. As of 25th January 2021, more than 100 million confirmed cases of 2,165,581 deaths have been reported by WHO and Worldometer. Many of the cases reported are caused by infection from human to human and are the carriers of this lethal coronavirus. Due to its calamitous nature, the whole world was under lockdown restricting all sorts of movements and means of transportation in hampering the countries economic balance. Presently, the world's endeavor to create and develop a safe and effective COVID-19 vaccine is bearing the fruit. A handful of vaccines now have been authorized around the globe and many more remain in the development phase. In addition, social isolation and knowledge of hygiene (facial masks and sanitizers) are potential methods of controlling the further dissemination of global pandemics COVID-19. This research article presents a brief overview of the catastrophic effect caused by COVID-19 disease globally and particularly in different states of India. Additionally, the article also discusses the recent variant of SARS-CoV-2 and its vulnerable impact. Furthermore, the article investigates the currently available vaccines and those in their development phase for the treatment of COVID-19 disease. This investigatory literature may provide comprehensive details on COVID-19 disease from its inception to grow and later fall in its strain rate.</p> 2021-05-07T00:00:00+0530 Copyright (c) 2021 Abdullah Anwar https://innovareacademics.in/journals/index.php/ijap/article/view/40664 DEVELOPMENT OF SUSTAINED RELEASE ALOGLIPTIN TABLETS USING A MULTIPARTICULATES SYSTEM MADE OF BENTONITE 2021-05-10T11:29:50+0530 RASHAD M. KAOUD rashadmk@yahoo.com ALHAMZA HOSHI KHALAF hamzakhalaf2900@gmail.com JAMAL ALYOUSSEF ALKRAD jamal.alkrad@iu.edu.jo <p><strong>Objective: </strong>This study was designed to evaluate the use of bentonite in the formulation of sustained-release tablets containing alogliptin benzoate after granulation.</p> <p><strong>Methods: </strong>Bentonite was used for preparing tablets after granulation. The prepared tablets were tested for their pharmacopeial requirements. Further, a high-performance liquid chromatography (HPLC) method was developed to assess the release pattern of alogliptin from the tablets. Besides, differential scanning calorimetry (DSC), fourier transform infrared spectroscopy (FTIR), and powder X-ray diffraction (XRD) were used for evaluating the compatibility the drugs and bentonite. Finally, the release from the tablets was tested using the paddle apparatus.</p> <p><strong>Results: </strong>The FTIR and DSC did not show any interaction between the drug and the excipient in contrast to the powder-XRD pattern, which showed a shift for montmorillonite crystal peak. This shift was interpreted by increasing in the spacing of the crystalline structure of montmorillonite. However, the results of pharmacopeial tests showed that the prepared tablets comply with the compendial requirements, In addition, the release profiles of these tablets with aid of hydroxypropyl methylcellulose (HPMC) as a binder revealed a sustained release of alogliptin. Furthermore, the fitting of release data showed that the release from these tablets followed Fickian diffusion that alogliptin released by diffusion from bentonite gel matrix.</p> <p><strong>Conclusion: </strong>Bentonite was successfully used for producing sustained-release tablets of alogliptin. However, maintaining the crystal structure of montmorillonite was essential for building the gel structure of bentonite and releasing the drug in a controlled manner.</p> 2021-05-07T00:00:00+0530 Copyright (c) 2021 Jamal Alyoussef Alkrad, Rashad Kaoud, Alhamza f Khala https://innovareacademics.in/journals/index.php/ijap/article/view/40605 FORMULATION AND EVALUATION OF AMPHOTERICIN B AND MILTEFOSINE COMBINATION NANOVESICLES 2021-05-10T11:20:57+0530 MULUGETA F.

RAMANA MURTHY befentie@gmail.com <p><strong>Objective: </strong>The aim of the present investigation is to formulate and evaluate amphotericin B-miltefosine combination nanovesicles for application in the treatment of visceral leishmaniasis.</p> <p><strong>Methods: </strong>Amphotericin B-miltefosine combination (AmB-MTF) nanovesicles were prepared by ethanol injection method. Formulations of nanovesicles were evaluated at varying conditions of lipids composition, drug-lipid proportion, ethanol-water composition and stirring rate, on drug entrapment efficiency and particle size.</p> <p><strong>Results: </strong>The study showed that entrapment efficiency was significantly affected (p&lt;0.01) by the effects of lipids composition, drug-lipid proportion, ethanol-water composition, and stirring rate. Particle size of nanovesicles was significantly affected (p&lt;0.05) by drug-lipid proportion and stirring rate. An optimized formulation of amphotericin B-miltefosine nanovesicles was prepared at optimal factors composition of: phosphatidylcholine-cholesterol-stearic acid 20:4:1, drug-lipid 1:8, AmB-MTF 1:1; ethanol-water 1:4 ratios, and stirring rate 1000 rpm. The AmB-MTF 1:1 nanovesicles formulation showed particle size of 145.6 nm, poly dispersity index 0.19, zeta potential-27.3 mV and drug entrapment efficiency 87%.</p> <p><strong>Conclusion: </strong>Evaluation of AmB-MTF 1:1 nanovesicles showed development of a successful formulation with very good compatibility, extended drug release, convenient vesicle size and high drug entrapment efficiency. To conclude, AmB-MTF 1:1 nanovesicles formulation could be a safe and reliable therapeutic option over the conventional combination therapy provided further antileishmanial investigations are investigated <em>in vitro </em>and <em>in vivo.</em></p> 2021-05-07T00:00:00+0530 Copyright (c) 2021 Mulugeta Bezabeh https://innovareacademics.in/journals/index.php/ijap/article/view/40604 FORMULATION AND EVALUATION OF IN-SITU GEL CONTAINING LINEZOLID IN THE TREATMENT OF PERIODONTITIS 2021-05-10T18:41:07+0530 INAYATHULLA . inaythmehdi@gmail.com PRAKASH GOUDANAVAR inaythmehdi@gmail.com MOHAMMAD ALI inaythmehdi@gmail.com SHAHID UD DIN WANI inaythmehdi@gmail.com NAGARAJA SREEHARSHA inaythmehdi@gmail.com <p><strong>Objective: </strong>The intent to prepare and evaluate Linezolid in-situ gel in the treatment of periodontitis.</p> <p><strong>Methods: </strong>pH-sensitive in-situ gel was formed by the cold method using a varying concentration of the drug, carbopol 934P and hydroxypropyl methylcellulose (HPMC) and carbopol 934P and sodium carboxy methylcellulose (CMC) (1:1,1:1.5,1:2,1:2.5). An optimized batch was selected based on gelling time and gelling capacity. The prepared in-situ gels were evaluated for appearance, pH, gelling capacity, viscosity, <em>in vitro</em> release studies, rheological studies, and finally, was subjected to drug content estimation and antibacterial activity test.</p> <p><strong>Results: </strong>FTIR study shows drug and physical mixture were compatible with each other. The rheology of formulated in-situ gel exhibited a pseudoplastic flow pattern. this may be because when polymer concentration was increased the prepared formulations become more viscous and in turn delayed the drug release and from the prepared formulation, LF4 and SF4 have polymer concentrations i. e, 0.9% carbopol and sodium CMC showed drug release up to 12 h<strong>. </strong></p> <p><strong>Conclusion: </strong>When carbopol is appropriately mixed with other suitable polymers it forms an in-situ gel-forming system that was substantiated by the property to transform into stiff gels when the pH is increased. The in-situ gel was prepared using a combination of carbopol-HPMC and carbopol-Na CMC The formulations LF1 to SF4 showed high linearity (R2 = 0.490-0.682), indicating that the drug was released from the prepared in-situ gel by the diffusion-controlled mechanism. Thus, the formulation of batches LF4 and SF4 containing carbopol: HPMC and carbopol: NaCMC in 1:2 ratios were considered as optimum formulation based on optimum viscosity, gelling capacity and to extend the <em>in vitro</em> drug release.</p> 2021-05-07T00:00:00+0530 Copyright (c) 2021 inayathulla https://innovareacademics.in/journals/index.php/ijap/article/view/40538 SYNTHESIS AND CHARACTERIZATION OF STARCH MALONATE: DEVELOPMENT OF FAST DISSOLVING TABLETS OF ACECLOFENAC BY 23 FACTORIAL DESIGNS 2021-05-10T10:02:16+0530 ANNU KUMARI drsantoshrada@gmail.com R.

DAS mkdps@dibru.ac.in <p><strong>Objective: </strong>Curcumin presents poor topical bioavailability when administered orally, which poses a major hurdle in its use as an effective therapy for the management of psoriasis. The present study reports the utilization of lipid-polymer hybrid nanoparticles (LPHNPs) for the topical delivery of curcumin which can be a potential approach for mitigating psoriasis.</p> <p><strong>Methods: </strong>Curcumin-loaded LPHNPs were prepared by the emulsification solvent evaporation method and characterized. The optimized Curcumin-loaded LPHNPs (DLN-3) were further incorporated into 2% Carbopol 940 gels and evaluated for its therapeutic efficacy in the Imiquimod (IMQ)-induced psoriasis rat model.</p> <p><strong>Results: </strong>The average particle size, polydispersity index, zeta potential, drug entrapment and loading efficiency for DLN-3 were found to be 200.9 nm, 0.342,-28.3 mV, 87.40±0.99% and 4.57±0.04%, respectively. FT-IR, DSC and XRD studies confirmed that all the components used for the formulation are compatible with each other, whereas SEM and TEM analysis affirmed the spherical shape of LPHNPs with a smooth surface. The <em>in vitro</em> drug release studies suggest that curcumin was released from the LPHNPs in a sustained manner over a period of 24 h via super case II transport mechanism. Results of <em>in vitro</em> skin permeation study revealed that 38.39±2.67% of curcumin permeated at 12 h across excised pig ear skin with a permeation flux of 18.74±3.59 µg/cm<sup>2</sup>/h. Further, <em>in vivo</em> evaluation and histopathological studies demonstrated that NLHG-1 hydrogels showed better therapeutic efficacy against the psoriatic skin lesions than the standard marketed gels.</p> <p><strong>Conclusion: </strong>These results suggest that the developed LPHNPs have a superior ability to improve the skin penetration or accumulation of DLN-3 within psoriatic skin and offer a potential delivery system for the management of psoriasis.</p> 2021-05-07T00:00:00+0530 Copyright (c) 2021 Malay K Das, Pankaj Kumar Jaiswal, Sanjoy Das https://innovareacademics.in/journals/index.php/ijap/article/view/41600 IN SILICO IDENTIFICATION OF APOBEC3B SMALL MOLECULE INHIBITORS FROM DTP-NCI LIBRARIES 2021-05-10T22:33:57+0530 MARYAN MOHAMUD MOHAMED kwng@msu.edu.my NOR ATIQAH JUSRIL kwng@msu.edu.my MOHD ILHAM ADENAN kwng@msu.edu.my N.

MUNDHEY dmundhey1990@gmail.com N. SAPKAL nidhisapkal@zimlab.in A. DAUD anwar.daud@zimlab.in <p><strong>Objective: </strong>The present research work aims to develop a microemulsion loaded sublingual film for rapid absorption of fentanyl citrate in transient breakthrough pain.</p> <p><strong>Methods: </strong>The Fentanyl citrate microemulsion loaded sublingual film was prepared using Capmul MCM C8 (oil), tween 20 (surfactant) and propylene glycol (co-surfactant) with different grades of film-forming polymer (HPMC) using a film casting machine. The films were evaluated for <em>in vitro</em> disintegration study, tensile strength, folding endurance, content uniformity, drug content, <em>in vitro</em> dissolution, pH, thickness and weight variation, scanning electron microscopy, ex vivo permeation study, droplet size, polydispersity index, zeta potential, % moisture content and stability study were evaluated.</p> <p><strong>Results: </strong>The optimized film formulation showed desired mechanical properties (tensile strength of 0.291 kg/cm<sup>2</sup>) and a minimum disintegration time of 20 s. The optimized sublingual film formulation exhibited 43.16 % of FC microemulsion loading. Morphological study showed the absence of drug crystals on the polymeric surface. Permeation studies through goat sublingual mucosa indicated 89% fentanyl citrate release through fentanyl citrate microemulsion loaded sublingual film, whereas only 40% fentanyl citrate release was obtained when it was directly added to film without microemulsion strategy.</p> <p><strong>Conclusion: </strong>The present study indicated that extend of permeation of fentanyl citrate when added to the sublingual film in microemulsion form was around 2.225 folds higher than when added directly to film without microemulsion. The present microemulsion embedded film technology could be a promising alternative to conventional drug delivery systems and traditional routes of administration for breakthrough pain management.</p> 2021-05-07T00:00:00+0530 Copyright (c) 2021 Dhanashree Mundhey, Nidhi Sapkal, Anwar Daud https://innovareacademics.in/journals/index.php/ijap/article/view/41202 VIRTUAL TARGET CONSTRUCTION FOR STRUCTURE-BASED SCREENING IN THE DISCOVERY OF HISTAMINE H2 RECEPTOR LIGANDS 2021-05-10T22:11:46+0530 GERRY NUGRAHA ge6nugraha@gmail.com ENADE PERDANA ISTYASTONO enade@usd.ac.id <p><strong>Objective</strong><strong>:</strong> This study aimed to develop validated targets to be employed in structure-based virtual screening (SBVS) to discover ligands for the human histamine H<sub>2</sub> receptor (hHRH2).</p> <p><strong>Methods</strong><strong>:</strong> The virtual targets construction was initiated by homology modeling with the reference compound ranitidine as the ligand followed by 100 ns molecular dynamics (MD) simulations. During MD simulations, the snapshot with the lowest value of the free energy of binding was selected for further validation by re-docking simulations. All simulations were performed in YASARA-Structure.</p> <p><strong>Results: </strong>The research presented here resulted in one validated target for the SBVS. Additionally, by employing a clustering module in MD simulations analysis in YASARA-Structure, more than ten different virtual targets are also available for further uses.</p> <p><strong>Conclusion</strong><strong>:</strong> The virtual targets resulted in this research offer possibilities to construct valid SBVS protocols to identify ligands for the hHRH2.</p> 2021-05-07T00:00:00+0530 Copyright (c) 2021 gerry nugraha, Enade Istyastono https://innovareacademics.in/journals/index.php/ijap/article/view/40975 RAPID AND SIMPLE DETERMINATION OF IBUPROFEN AND CAFFEINE IN FIXED-DOSE COMBINATION FORMULATIONS: APPLICATION TO DISSOLUTION STUDIES 2021-05-10T15:28:13+0530 JOSE RAUL MEDINA-LOPEZ rmlopez@correo.xoc.uam.mx JOAQUIN ALEXANDRO SOTO-JUHA alex5oto@hotmail.com JUAN MANUEL CONTRERAS-JIMÉNEZ juanmanuel_contreras92@outlook.com <p><strong>Objective: </strong>To develop a UV-derivative spectrophotometric method with zero-crossing determinations for the simultaneous quantification of ibuprofen (IBU) and caffeine (CAF) in fixed-dose combination formulations (soft gelatin capsules). The proposed method was validated, and it was applied to determine the <em>in vitro</em> dissolution performance of IBU and CAF from a commercial formulation.</p> <p><strong>Methods: </strong>The method is based on the use of the second-derivatives of the zero-order spectra and measurement at zero-crossing wavelengths. Linearity, accuracy, precision, stability, and influence of the filter were evaluated. Dissolution profiles of IBU and CAF were obtained with the USP Apparatus 2 at 100 rpm and 900 ml of 0.1 M phosphate buffer pH 7.4 as dissolution medium. Dissolution samples were treated with the proposed UV-derivative method and results were compared with data previously published.</p> <p><strong>Results: </strong>The zero-crossing points for the determination of IBU and CAF were found at 235.6 nm and 218.8 nm, respectively. The method was linear in the range of 7.5-15 µg/ml for IBU and 5-25 µg/ml for CAF (R<sup>2</sup>&gt;0.999, *P&lt;0.05). The precision and accuracy of the method were within acceptable criteria (CV&lt;0.99% and recovery 97.97% for IBU and CV&lt;1.76% and recovery 99.05% for CAF). Fiberglass filters were the best option to filter samples and stability of all drugs was adequate when solutions were stored at 25 °C during 24 h. Dissolution of IBU and CAF at 60 min was 99-100% with dissolution profiles of sigmoidal S-shape. Weibull function and Logistic were the best-fit models that describe the <em>in vitro</em> dissolution performance of both drugs.</p> <p><strong>Conclusion: </strong>The proposed UV-derivative method allows the simultaneous determination of IBU and CAF in fixed-dose combination formulations. The method generates reliable information that can be compared with published data. The proposed UV-derivative method is rapid and simple and can be easily adopted for routine analysis of IBU and CAF.</p> 2021-05-07T00:00:00+0530 Copyright (c) 2021 Jose Raúl Medina-López, Joaquín Alexandro Soto-Juha, Juan Manuel Contreras-Jiménez
