This is due to highly expensive process and high attrition rates of existing marketed drugs. Hard-boiled lozenges (HBLs) are one of the solid dosage form designed to release the drug in saliva for either local or systemic effects. Typical application of lozenegs includes throat infection, pharyngitis, cough suppressant, nasal-decongestant, expectorants, and smoking cessation. The drug delivery through the hard-boiled candies has an easy marketing advantage due to its attractive appearance and patient compliance. As a part of the drug is absosrbed into systemic circulation, gastrointestinal degradation and fast pass effects are avoided. Further, drug delivery through hard-boiled lozenges can be potential platform for some of the suitable drug candidates. This review on hard-boiled lozenges discusses manufacturing process, characterization techniques, quality control, research studies and market potential of hard-boiled lozenges. The major databases searched were, PubMed, Wiley Online, Medline, Elsevier, Google scholar, Scopus, ACS, The Royal Society of Chemistry, SciFinder, Baidu Scholars, CNKI, web of science, Cochrane database, US Patents, Espacenet and various business reviews. This review provides comprehensive information on hard-boiled lozenges that will help the pharmaceutical scientist from academia as well pharmaceutical industry to leverage the potential of this conventional dosage form for various herbal drugs and other pharmaceutical actives.</p> 2021-03-07T00:00:00+0530 Copyright (c) 2021 Manas Ranjan Sahoo, Umashankara Marakanam Srinivasan, Dr. Ramesh Raghava varrier AN OVERVIEW OF TECHNOLOGY TRANSFER AS A REGULATORY ASPECT 2021-03-11T12:55:52+0530 G. M. PAVITHRA MANORANJITH S. NAGALAKSHMI <p>Technology Transfer is fundamental and crucial to the drug development process for new drug products. The great decision is based on that factor in which the concept or process is advanced from research and development-oriented scheme to aimed towards the commercialization of the drug. The transfer could also be said to achieve success if the receiving section and the transferee can efficiently use the technology for profit. The achievement relies upon an understanding of the process or the capability to predict exactly the future prospects of a process. The main intention of this review article is to study the Regulatory aspects of technology transfer. This review article is mainly focused on the Consequence of technology transfer, the purpose for technology transfer in industries, barriers concerned with technology transfer, classification regarding technology transfer, facets of technology transfer, and steps among technology transferThis review was carried out by systematic searches of data integrity in relevant ICH, WHO, and US guidelines, published articles, reviews and abstracts in Google scholar, Pubmed, Science direct, Embase, Web of science of articles up to 2020.</p> 2021-03-07T00:00:00+0530 Copyright (c) 2021 Dr.S.

SITOHANG <p>Acne vulgaris (AV) occurs in more than 80% of dermatological cases in adolescents and young adults and affects the quality of life. Oral isotretinoin, a metabolite product of vitamin A, is well-known to be the most effective treatment for severe nodulocystic AV and moderate AV that does not respond to other therapeutic modalities. Thus, this literature review was conducted to explain the mechanism of action, effectiveness, contraindications, side effects, and safety of oral isotretinoin in AV, which provided essential information for dermatologists. Furthermore, isotretinoin is the only treatment modality that has implications for the entire pathogenesis of acne. It contributes to decreasing corneocytes’ adhesion, supporting cellular proliferation and follicular renewal, induction of cell apoptosis, and immune regulation. The effectiveness of AV therapy with isotretinoin has expanded as it is also indicated for moderate to severe AV that does not respond well to topical combination therapy or systemic antibiotics. However, isotretinoin is included in Category X drugs and may induce many side effects from mucocutaneous effects to teratogenicity. From this extensive literature review, it can be concluded that isotretinoin is one of the treatment modalities for acne with good effectivity due to its mechanism of actions that affect the entire acne pathogenesis. Considering the various side effects of isotretinoin, its use requires adequate clinical assessment and monitoring by a dermatologist.</p> 2021-03-07T00:00:00+0530 Copyright (c) 2021 Irma Sitohang TREATMENT POSSIBILITIES FOR ACQUIRED AND HEREDITARY DISEASES BY GENE THERAPY: A REVIEW 2021-03-11T12:56:57+0530 P. V. KAMALA KUMARI G. EKSHITHA, V. HARIKA <p>Therapeutic nucleic acids demand specificity and accuracy in design as well as delivery strategies used in replacement or silencing of the target gene. Gene therapy is believed to be the therapy in which the root cause of the diseases can be treated at the molecular level. Generally gene therapy helps in the identification of the origin of the disorder instead of using drugs to diminish or control the symptoms. The application of nucleic acids to treat and control diseases is known as “gene therapy.” Gene therapy consists on the substitution or addition of a functional gene into the nucleus of a living cell, in order to treat a disease or repair a dysfunction, caused by this gene failure. This therapy is used to correct defective genes, which are responsible for genetic diseases. Thus, gene therapy can be used to prevent, treat or regulate hereditary or acquired disorders, by the production of therapeutic proteins. The gene therapy is mediated by the use of viral and non-viral vectors to transport foreign genes into somatic cells to restorative defective genes. This review focuses on viral vectors in detail.</p> 2021-03-07T00:00:00+0530 Copyright (c) 2021 Kamala Kumari Paravastu SAMPLE PREPARATION AND BIOANALYSIS VALIDATION FOR NATURAL PRODUCT SAMPLE 2021-03-10T19:30:15+0530 IDA AYUMIATI FEBRINA AMELIA SAPUTRI MUCHTARIDI MUCHTARIDI <p>Bioanalysis study and its validation are important for the application in natural drug discovery and preparation for natural medicine products with safe drug development approaches. Bioanalysis data for natural products can provide quantitative information on active compounds from natural products for pharmacokinetics, pharmacodynamics, bioavailability, bioequivalence, and toxicokinetics. Bioanalysis validation provides useful guidance for obtaining accurate data on drug discovery, preclinical and clinical testing of natural drug product development, and to ensure the methods used are suitable for application in testing the samples. In general, sample preparation and validation of the bioanalysis method are part of the pharmacokinetic characterization of a chemical compound from the discovery to the development stage of natural material products. Therefore, this paper aims to discuss how to prepare samples and validate bioanalysis for natural products.</p> 2021-03-07T00:00:00+0530 Copyright (c) 2021 Ida Ayumiati TREATMENT MODALITIES OF THE COVID-19 PANDEMIC THROUGH REPURPOSED DRUGS AND STATUS OF VACCINES 2021-03-12T13:29:32+0530 MD SADIQUE HUSSSAIN MOHIT PARUL PAMMA BABY KUMARI <p>Respiratory diseases are&nbsp;the leading source of morbidity and death&nbsp;for millions around the world of all ages. A 2019 coronavirus&nbsp;outbreak has occurred in China&nbsp;and is spread quickly throughout nearly all&nbsp;across the world. To introduce prevention measures that have contributed to a sudden upturn in the rate of cases around the globe, several nations responded too late.

K. DHANABAL S. P. SURESHKUMAR R. CHENMALA KARTHIKA SAI SURYA NIKITHA UPADHYAYULA <p>COVID-19 is a life-threatening disease that mainly affects the human respiratory system. In today’s world, scientists are working conscientiously for the identification of promising drugs and vaccines. But, when we look back to the former times, herbal medicines were considered for curing most of the diseases; luckily, nowadays, natural remedies are being carried forward by few researchers even for the treatment of most life-threatening diseases like cancer, diabetes and alzheimer’s etc. So, why can't we attempt the herbal formulation for the management of COVID-19 too? Since there is no proper scientific validation for traditional herbs and spices; it just can’t be simply ignored. When a product with less or few side effects can be prepared and made available for the benefit of people, there is nothing wrong in pondering them. Thus, keeping these points in mind, in this article, we have discussed about SARS CoV-2, their treatment options and the impact of natural remedies on both the former as well as novel coronavirus. Further, we have also emphasized on traditional Chinese medicine, various flavonoids and kabasura kudineer and their impact on coronavirus infection. Till now, there is no particular drug or vaccine available for the treatment of COVID-19; thus prevention is the only option. But, we hope that thorough study; screening, preclinical and clinical evaluation of natural compounds may give some action against SARS CoV-2. Moreover, incorporating natural herbs and spices in our diet can help in boosting immunity and fight against various life-threatening diseases.</p> 2021-03-07T00:00:00+0530 Copyright (c) 2021 Janani S.K., Dr. Dhanabal S.P, Dr. Raman Sureshkumar, Sai Surya Nikitha Upadhyayula, Karthika Chenmala NOSE-TO-BRAIN DRUG DELIVERY: AN UPDATE TO THE ALTERNATIVE PATH TO SUCCESSFUL TARGETED ANTI-MIGRAINE DRUGS 2021-03-11T19:28:21+0530 SOUVIK CHATTOPADHYAY SUJIT DAS KOUSHIK NARAYAN SARMA <p>The Blood-Brain Barrier (BBB) limits transportation to the brain of possible treatment moieties. Specific stimulation of the brain through olfactory and trigeminal neural pathways by BBB has been taken into consideration for the development of a wide spectrum of brain therapeutics. The intranasal delivery path delivers the drugs through the brain, eliminating any side effects and increasing neurotherapeutics performance. Diverse drug delivery systems (DDDss) for reaching the brain via the nasal route have been researched over the past few decades. Large-scale molecular biologics, such as Deoxyribonucleic acid (DNA), gene vectors, and stem cells, can be administered intranasally, as a method for the management of a range of CNS illnesses, including stroke, Parkinson's diseases, multiple sclerosis, Migraine, Alzheimer's diseases, epilepsy, and mental disorders. New DDSs, including nanoparticles, liposomes, and polymeric micelles, have acquired potentials in the nasal mucosa and central nervous system (CNS), as effective means of concentrating the brain without toxicity. Differential nasal cavity structures posed a significant obstacle in ineffective drugs beyond the nasal valve. Pharmaceutical firms have increasingly used emerging techniques for the production of new nasal pharmaceutical drugs to overcome these obstacles. This review aims to identify the new advances in the nasal administration of brain-based DDSs for Migraines.</p> 2021-03-07T00:00:00+0530 Copyright (c) 2021 Souvik Chattopadhyay, Sujit Das, Koushik Narayan Sarka UFASOMES: UNSATURATED FATTY ACID BASED VESICULAR DRUG DELIVERY SYSTEM 2021-03-10T19:56:41+0530 ARUNDHASREE RAJALAKSHMI R. AISWARYA R. ABHIRAMI RAJENDRA KUMAR SREELAKSHMI S. KUMAR SREEJA C. NAIR <p>Various novel drug delivery systems have been developed encompassing several administration routes to deliver drugs at a rate decided as per the need of the body during the course of treatment and to achieve targeted therapy, also decreases undesirable side effects. Different types of vesicular drug delivery systems were developed, such as liposomes, niosomes, ufasomes etc. Ufasomes are unsaturated fatty acid vesicles which is a suspension of closed lipid bilayer formed from fatty acid and their ionized species having limited, narrow pH ranging from 7-9. Composition of fatty acid molecules is such that the hydrocarbon tails are pointed towards the inner core of the membrane and the carboxyl group are in touch with water. Stable ufasomes preparation mainly relies on appropriate choice of fatty acid, cholesterol quantity, range of the pH, buffer and lipoxygenase amount. Recent innovation provides very efficient features such as stability considerations, dynamic features and microscopic features of ufasomes. The article furthermore provides the difference between ufasomes with liposomes. For this review, the complete databases have been collected from various search engines such as researchgate, elsevier, pubmed, sciencedirect, google scholar, scopus etc., from the year 1965-2020 using the following keywords.</p> 2021-03-07T00:00:00+0530 Copyright (c) 2021 sreeja c nair, arundhasree, rajalakshmi r, aiswarya r, abhirami rajendra kumar, sreelakshmi s kumar BINGE EATING DISORDERS; UPDATED AND EMERGING APPROACHES 2021-03-11T14:52:53+0530 MAHMOUD TEAIMA MAGDI M.

A multidisciplinary strategy including pharmacotherapy is required for its management.</p> <p><strong>Methods: </strong>This review is intended to comparatively evaluate the relative efficacy of different pharmacological agents in BED treatment with new therapeutic approaches, focusing on the clinical evidence and on Phase III randomized controlled trials.</p> <p><strong>Results: </strong>Data suggest that certain treatments have advantages over placebos to reduce binge eating features; however, the small duration of such research with the lack of adequately sized trials was the major limitation in interpreting these findings. Furthermore, these medications are mostly not greatly efficient for BED associated with obesity except for topiramate, which markedly improves the features of binge episodes with weight loss. Till now, lisdexamfetamine is still the only drug with regulatory permission for BED therapy; however, its weight loss efficacy has not been established.</p> <p><strong>Conclusion: </strong>Drugs alone or in combination approaches may be useful pharmacotherapies to yield promising outcomes acutely and over longer-term follow-up in the treatment of BED.</p> 2021-03-07T00:00:00+0530 Copyright (c) 2021 mahmoud teaima, Magdi Abdel Hamid, Nabil Shoman, Bhaskara Jasti, Mohamed El-Nabarawi, Mohamed Yasser NIOSOMES AS AN APPROACH TO IMPROVE THE SOLUBILITY AND BIOAVAILABILITY OF BCS CLASS II DRUGS 2021-03-11T19:41:03+0530 GAURANG SAWANT GEETA BHAGWAT <p>Based on their solubility and permeability, drugs are typically divided into four classes (Classes I–IV) according to the biopharmaceutics classification system (BCS). Of these classes, BCS class II drugs have high permeability and low solubility; not only do these characteristics constitute the rate-limiting step in the formulation of these drugs but the low solubility in water results in low bioavailability. Thus, methods for improving their solubility have been developed using lipid carriers such as liposomes, niosomes, and aquasomes; other approaches include self-micro-emulsifying drug delivery systems (SMEDDS) and self-nano-emulsifying drug delivery systems (SNEDDS). Currently, niosome-based drug delivery systems that utilize nonionic surfactants, drugs, and cholesterol in varying ratios are being widely used to deliver both hydrophilic and lipophilic drugs in addition to several other applications of niosomes.</p> 2021-03-07T00:00:00+0530 Copyright (c) 2021 Gaurang Sawant, Geeta Bhagwat THERMOSENSITIVE HYDROGELS–A POTENTIAL CARRIER FOR THE DELIVERY OF DRUGS AND MACROMOLECULES 2021-03-11T14:23:49+0530 SOUMYA RANJANA SAHOO MOTHILAL M.

Optimized emulsomes were characterized for morphological features, <em>in vitro</em> drug release kinetics and protection from plasma protein.</p> <p><strong>Results: </strong>The emulsomes so formed were uniform in size with a mean particle diameter of 275±5.52 and 195±6.4 nm for P-Es and SS-Es respectively. All the formulations showed pH dependent drug release with a slow and sustained release profile. Slower drug release was observed from sterically stabilized emulsomes than the plain emulsomes. The drug release profile followed the Higuchi model with the Fickian diffusion pattern. The Pegylation of emulsomes significantly reduced the <em>in vitro</em> protein absorption.</p> <p><strong>Conclusion: </strong>The sterically stabilized emulsome can serve as a novel non-toxic platform with longer circulatory time for the delivery of Paclitaxel and other poorly water-soluble drugs as well.</p> 2021-03-07T00:00:00+0530 Copyright (c) 2021 Surbhi Dubey, S.P.

PARIMALA Y. YAMINI M. PHANINDRA CVS SRINIVASA RAO Y. <p><strong>Objective: </strong>Ramelteon, is a sleep agent that selectively binds to the&nbsp;MT<sub>1</sub>&nbsp;and MT<sub>2</sub>&nbsp;receptors&nbsp;in the&nbsp;suprachiasmatic nucleus (SCN), instead of binding to&nbsp;GABA<sub>A</sub>&nbsp;receptors. In the present research work, the formulation of ramelteon targeted to colon by using various polymers developed.</p> <p><strong>Methods: </strong>Colon-targeted tablets were prepared in two steps. Initially, core tablets were prepared and then the tablets were coated by using different pH dependent polymers. Ethylcellulose, Eudragit RLPO and L100 were used as enteric coating polymers. The precompression blend of all formulations was subjected to various flow property tests and all the formulations were passed the tests. The tablets were coated by using polymers and the coated tablets were subjected to physical characterization, drug content, <em>in vitro</em> drug release and kinetics of drug release.</p> <p><strong>Results: </strong>Among all the formulations, F4 formulation was found to be optimized as it was retarded the drug release up to 18 h and showed maximum of 99.25% drug release. It followed the first-order kinetics mechanism. All the formulations having Korsmeyer-Peppas ‘n’ values are in the range of 0.540 to 0.818. Hence, it was concluded that the prepared formulations followed non-Fickian diffusion.</p> <p><strong>Conclusion: </strong>An effective and stable remelteon colon targeted formulation developed for treating insomnia.</p> 2021-03-07T00:00:00+0530 Copyright (c) 2021 Trinadha Rao Mamidi DESIGN AND CHARACTERIZATION OF NANOSPRAY WITH SELF-NANOEMULSIFYING DRUG DELIVERY SYSTEM USING SINERGISTIC COMBINATION OF MELASTOMA MALABATHRICUM L. FRACTION AND GENTAMICIN 2021-03-11T13:49:27+0530 LIZA PRATIWI RAFIKA SARI PRATIWI APRIDAMAYANTI <p><strong>Objective: </strong>This study aimed to design a formula using Design-Expert software to obtain optimal Self-Nanoemulsifying Drug Delivery System (SNEDDS) formulas and to analyze nanospray characteristics of optimal SNEDDS.</p> <p><strong>Methods: </strong>The study began with preparing ethanol extract from <em>Melastoma malabathricum</em>. The extract was then fractionated using ethyl acetate. The formulation design stage began with a solubility test of <em>Melastoma malabathricum</em> fraction and gentamicin (MFG) in various surfactants, co-surfactants and oils. Furthermore, the 14 formula of SNEDDS with various compositions of the selected surfactants, co-surfactants and oils were formulated and evaluated with pH response and emulsification time. Analysis was carried out using Design-Expert software with the simplex lattice design method in order to obtain the optimal formula profile. The pH, emulsification time, particle size, and zeta potential of the nanospray from SNEDDS optimal formulas were physically characterized. Stability of SNEDDS and the nanospray was then tested with freeze-thaw cycling and <em>in vitro</em> diffusion studies with Franz diffusion.</p> <p><strong>Results</strong>: Based on the study, the ratios of optimal formula SNEDDS composition of Tween 80, propylene glycol, and soybean oil were 2.69: 2.64: 1.67 parts. Nanospray with SNEDDS technology had characteristics of pH 5.61±0.16, emulsification time 7.68±0.18, particle size 270.7 nm, and zeta potential-37.20 mV, and it was stable.</p> <p><strong>Conclusion: </strong>Nanospray can be formulated from optimal SNEDDS using Design-Expert software. Nanospray with SNEDDS technology has physical characteristics and is stable. <em>In vitro</em> diffusion studies revealed that the release of <em>Melastoma malabathricum</em> from nanospray was faster than that without preparation.</p> 2021-03-07T00:00:00+0530 Copyright (c) 2021 liza pratiwi COMPARATIVE STUDY OF SEVEN BRANDS OF LEVOFLOXACIN 500 MG FILM-COATED TABLET MARKETED IN YEMEN 2021-03-11T15:00:15+0530 GAMIL Q. OTHMAN YASER M. AL-WORAFI MOHAMMED M. BATTAH ABDULSALAM M. HALBOUP HASSAN M. HASSAN <p><strong>Objective: </strong>The objective of the current study was to evaluate the quality control parameters of seven brands of levofloxacin 500 mg film-coated tablet available in the Yemeni market.</p> <p><strong>Methods: </strong>Physicochemical parameters assay was performed for seven brands of levofloxacin 500 mg film-coated tablet. Each brand was subjected to official and unofficial <em>in vitro</em> quality control tests, including weight variation, thickness, hardness, friability, disintegration, dissolution, and content uniformity assay by High-Performance Liquid Chromatography (HPLC).</p> <p><strong>Results: </strong>Out of seven, six brands of levofloxacin 500 mg film-coated tablet passed official specified assay tests according to the United States Pharmacopeia (USP) specifications. They showed a similar profile of thickness ranged between±0.01 and 0.10%, friability ranged between 0.01% and 0.34%, disintegration time ranged between 3.00 and 15.00 min, dissolution percentage ranged between 90.650 and 103.05 and content uniformity ranged between 93.62 and 107.12%. Regarding weight variation and hardness, six brands passed the weight variation test and only three brands showed optimum range (10-20 kg) of hardness test. Only one brand failed to pass the weight variation test, and four brands failed to pass the optimum range (10-20 kg) of hardness.</p> <p><strong>Conclusion: </strong>There are no remarkable differences between the seven brands regarding in vitro quality control tests of content uniformity, thickness, friability, disintegration, and dissolution. Even though four brands were above the optimum range of hardiness, they showed complete disintegration and dissolution within the acceptable limit. Regular assessment of marketed drugs is required to ensure bioequivalent to their innovators.</p> 2021-03-07T00:00:00+0530 Copyright (c) 2021 Mohammed Battah, GAMIL QASEM OTHMAN, ABDULSALAM M.

HASSAN FORMULATION OF GEL FROM GYNURA SEGETUM EXTRACT AND ITS ACTIVITY ON BURN WOUND HEALING 2021-03-13T12:45:17+0530 ARIF BUDIMAN MUHARAM ANIDA CRISTI MAULIDA DIAH LIA AULIFA <p><strong>Objective</strong>: The aims of this study were to formulate gel from <em>Gynura segetum</em> (GS) extract and evaluate its burn-healing activity.</p> <p><strong>Methods: </strong>GS extract was formulated using carbomer and carboxymethylcellulose (CMC) as a stabilizer with various concentrations. Furthermore, the gel of GS extract was evaluated, including organoleptic, pH and viscosity. A burn-healing evaluation was conducted by making a wound with a hot plate on male Wistar rats, and 600 mg of the gel was applied. Subsequently, the presence of erythema and width contraction of the burns were observed for 15 d.</p> <p><strong>Results: </strong>The result showed that the formulation containing 1 % of carbomer and 1.2 % of GS extract has the best physical stability. The gel also increased the rate of the healing process with decreased burn wound contraction (5.67 mm after 15 d) and the erythema than the control (8.50 mm after 15 d). The significance value was less than 0.05, indicating that the rate of the healing process was significantly different between the GS extract gel and the control.</p> <p><strong>Conclusion: </strong>This finding demonstrated that the gel of GS extract can significantly improve the burns wound healing process and may also be safely used for topical preparation.</p> 2021-03-07T00:00:00+0530 Copyright (c) 2021 ARIF BUDIMAN, ANIDA CRISTI MAULIDA; diah lia aulifa
