Box-Behnken design with 3 factors, 3 levels and 3 responses was used to optimize the prepared nanoparticles. The independent variables were taken as A) Erlotinib concentration B) LCP concentration and C) Incubation time with responses R1) Drug entrapment efficiency R2) Drug Release and R3) Particle size. The correlation between factors and responses were studied through response surface plots and mathematical equations. The nanoparticles were evaluated for FTIR, particle size and zeta potential by Photon correlation spectroscopy (PCS) and surface morphology by TEM. The entrapment efficiency, and <em>in vitro </em>drug release studies in PBS pH 7.4 (26 h) were carried out. The experimental values were found to be in close resemblance with the predicted value obtained from the optimization process. The <em>in vitro</em> cytotoxicity studies of the prepared nanoparticles in lung cancer cell line (A 549) were studied with different concentrations for 24h.</p> <p><strong>Results</strong><strong>:</strong> The average particle size, zeta potential, Polydispersity index (PDI) were found to be 292.1 nm,-25.8 mV and 0.384 respectively. TEM image showed that the nanoparticles dispersed well with a uniform shape and showed not much change during storage. The <em>in vitro</em> drug release showed 41.23% for 26 h in PBS (7.4) and release kinetics showed highest R<sup>2</sup>value (0.982) for Korsmeyer-Peppas model, followed by 0.977 for Higuchi model. The <em>in vitro</em> cytotoxicity of prepared nanoparticles in A 549 cell line showed good results with different concentrations for 24h.</p> <p><strong>Conclusion: </strong>Erlotinib (Erlo) is a BCS class II drug with poor solubility, poor bioavailability and selective tyrosine kinase inhibitor for non small-cell lung cancer (NSCLC) through oral administration. To improve the oral bioavailability and absorption of molecules, plant protein as carriers is used for developing drug delivery systems due to their proven safety. The optimization variables were Conc of Erlo, Conc. of LCP and Incubation time to get responses as drug entrapment efficiency, drug release and particle size. The compatibility between drug and LCP were evaluated by FTIR. </p> GEETHA V. S.

The sterile solution of the injectable dosage form LCS-1208 is poured into sterile vials using a dispenser and lyophilized in a freeze-drying chamber. At the end of drying, the preparation is corked in the chamber of a sublimation unit using a hydraulic device and transferred to crimping with aluminum caps using a seaming machine. Quantitative determination of the drug content was determined by spectrophotometry using a standard sample at λ = 320±2 nm. The pH was determined by potentiometry.</p> <p><strong>Results: </strong>A freeze-drying regimen for the injectable dosage form LCS-1208 has been developed. The required solution freezing temperature was established taking into account the presence of 2 eutectic zones: a solution of LCS-1208 in DMSO (-35 ÷-32) °С, an aqueous solution of Kollidon 17PF (-10 ÷-8) °С. As a result of a series of experiments, the optimal lyophilization regime was chosen that does not require preliminary freezing in a low-temperature chamber, with freezing on the shelves of freeze-drying at a temperature of-47 °C without their preliminary cooling. The most acceptable vial filling volume was determined, amounting to 3 ml, and the rate of temperature rise during secondary drying of the preparation was justified. When using the developed regime of lyophilization of the LCS-1208 solution, it was shown that it can be sublimated while preserving the initial qualitative and quantitative characteristics.</p> <p><strong>Conclusion: </strong>In this article, using the example of creating a lyophilized injectable dosage form LCS-1208 (the original antitumor drug from the indolocarbazole group), the main problems that arose during the lyophilization of the selected composition of the model solution, as well as ways to improve the process.</p> ILYA GULYAKIN ANNA LANTSOVA LYUDMILA NIKOLAEVA MARIA DMITRIEVA NATALIYA OBOROTOVA OLGA ORLOVA NATALIA ZHURAVLEVA Copyright (c) 2021 Ilya Gulyakin, Anna Lantsova, Lyudmila Nikolaeva, Maria Dmitrieva, Nataliya Oborotova, Olga Orlova, Natalia Zhuravleva 2021-07-07 2021-07-07 102 105 10.22159/ijap.2021v13i4.41371 THE EFFECT OF BANGGAI YAM (DIOSCOREA ALATA L.)

Powder obtained was each physically and chemically characterized including organoleptics, morphology, tapped density, water content content and degree of substitution. Furthermore, the formulation was made to produce film-coated drug with the same coating agent concentration in 2 formulas: F1 (PGBYSP 6 %) and F2 (PGBYS 6 %).</p> <p><strong>Results: </strong>The results were then evaluated including organoleptics, film thickness, morphology, mechanical strength, and film solubility. Results of evaluation showed that film thickness values for both formulas, ​​F1 and F2 respectively, were 0.13±0.020 mm and 0.18±0.005 mm. Mechanical strength included tensile strength consecutively at values of F1= 0.08±0.005 MPa and F2= 0.27±0.05 MPa; % elongation of F1= 114.16±11.8 % and F2= 164.06±57.94%; Young's modulus of F1= 7.3×10<sup>4</sup>±9.8×10<sup>-5</sup> MPa and F2= 1.8×10<sup>3</sup>±7.9×10<sup>-4</sup> MPa. The solubility of the film-coating in HCl pH 1.2 medium for F1 was 7.9±1.92% and F2 was 25.8±2.42%. In pH 6.8 medium, F1 was 8.6±2.27% and F2 was 11.6±1.44%, while in pH 7.4 medium, F1 was 19.1±5.46% and F2 was 13.1±1.78%. Both film-coated formulas were soluble in alkaline medium, but F2 could not maintain its conditions in acid medium. This proves that the chemical modification product by esterification to form a film can withstand acidic medium.</p> <p><strong>Conclusion: </strong>Therefore, PGBYSP has potential to be used as a coating agent in controlled release drug.</p> YUSRIADI EVI SULASTRI ATHIYAH NUUR AANISAH Copyright (c) 2021 Yusriadi, EVI SULASTRI, Athiyah, Nuur Aanisah 2021-07-07 2021-07-07 106 110 10.22159/ijap.2021v13i4.41343 HPLC ANALYSIS OF AMINO ACIDS CONTENT IN CRAMBE CORDIFOLIA AND CRAMBE KOKTEBELICA LEAVES https://innovareacademics.in/journals/index.php/ijap/article/view/41265 <p><strong>Objective: </strong>The aim of our study was to establish the content of some primary metabolites, such as amino acids in <em>Crambe cordifolia</em> and <em>Crambe koktebelica</em>.

This compound has remarkable potential pharmacological properties, including being anti-inflammatory, antimicrobial, anticancer, anticonvulsant, antidepressant, neuroprotective, and hepatoprotective. Recent studies have reported piperine activity as an antiviral against SARS-CoV-2, which caused COVID-19. Nevertheless, the clinical use of piperine is still limited, due to its poor water solubility and bioavailability; therefore, various approaches have been developed in order to solve these limitations. This review summarises recent studies (i.e. uploaded to electronic databases in the last 10 y) regarding strategies that have been investigated to improve piperine’s solubility and pharmacokinetic properties, using ‘piperine’, ‘solubility’, ‘bioavailability’, and ‘formulation’ as keywords. Articles that have focused on piperine as the main compound were selected and sorted based on their modification and formulation types. Studies reported various approaches: from derivatives and analogue synthesis, crystal engineering, complexation, particle size reduction (micro-and nanonisation), and lipid-and polymer-based drug delivery systems, to inorganic and hybrid nanoparticles. This review also highlights limitations and challenges for these approaches and encourages further studies to optimise piperine’s potential benefits.</p> HULWA SALSABILA LILI FITRIANI ERIZAL ZAINI Copyright (c) 2021 Erizal Zaini, Hulwa Salsabila, Lili Fitriani 2021-07-07 2021-07-07 31 39 10.22159/ijap.2021v13i4.41596 RECENT APPROACHES INVOLVED IN COLONIC DRUG TARGETING FOR THE TREATMENT OF INFLAMMATORY BOWEL DISEASE: A REVIEW https://innovareacademics.in/journals/index.php/ijap/article/view/40893 <p>The objective of the review is to present the contemporary approaches involved in colonic drug targeting for the therapy of inflammatory bowel disease (IBD). The adverse reactions and side-effects of the conventional drug delivery systems are largely on account of the systemic absorption of the drugs from the small intestine. Moreover, in current drug delivery systems, the drug has to be frequently administered and also in larger doses which greatly reduces patient compliance. Various approaches which are being described here mainly target the colonic region specifically for improved therapy of IBD, by increasing localization and accessibility of the drug to the target site. Also, these approaches will result in the reduction of dose and minimization of adverse effects combined with the use of conventional drug delivery systems.</p> SWAMINATHAN V. VAIYANA RAJESH C.

Alpha-mangostin is one of the secondary metabolites of <em>G. mangostana</em> and has been reported to have several pharmacological activities. The Biopharmaceutics Classification System (BCS) is a system that classifies drugs based on their solubility and permeability. Due to its low solubility but high permeation, alpha-mangostin is categorized into class II of the Biopharmaceutics Classification System. Therefore, the determination of dosage forms and modification of solubility enhancers is limited due to its physical properties, as mentioned above. This disadvantage requires new methods to improve its solubility to administer alpha-mangostin, especially for oral administration. Here, we discuss the development of the methods to increase alpha-mangostin solubility to be applied to formulate a dosage form to reach a useful plasma level for medication.</p> NURUL FAJERIYATI MUCHTARIDI MUCHTARIDI IYAN SOPYAN Copyright (c) 2021 Nurul Fajeriyati 2021-07-07 2021-07-07 47 54 10.22159/ijap.2021v13i4.39065 PHARMACOTECHNICAL DEVELOPMENT AND OPTIMIZATION OF MULTILAYERED TABLETS: AN UPDATED INDUSTRIAL REVIEW WITH EMPHASIS ON BILAYER TABLETS https://innovareacademics.in/journals/index.php/ijap/article/view/41528 <p>Fixed-dose combination formulations are multilayered platforms designed for solving complex medication regimens and overcoming polypharmacy problems especially in chronic diseases with geriatric patients. Multilayered tablets are considered promising avenues to combine different active pharmaceutical ingredients (APIs) for a synergic therapeutic effect, or different formulations of the same API in order to achieve a specific drug release profile. Besides, multilayered tablets can extensively help in avoiding possible interactions between different drugs, as well as optimizing each formulation individually in terms of pharmacokinetics and manufacturability. This review article discusses the most suitable materials used in the manufacturing of multilayered tablets, describes novel approaches to manufacturing improvement and process parameters, the influence of process parameters on layer adhesion, and the characterization tests of multilayered tablets.</p> AHMED M.

The first position reflects an increase in the kinetic isotope effect (KIE) in processes involving known pharmaceutical substances in aqueous solutions with a deuterium/protium ratio (D/H) below natural. For the first time, the dose-response diagram shows the identity of deuterium with essential trace elements, when a deficiency and excess of an element reduces the organism's vitality. Improved kinetic characteristics are demonstrated for the molecular and organism levels of different hierarchical gradations. In particular, they consist in the possibility of increasing the dissolution rate of substances by influencing the carbohydrate mutarotation processes and the optical activity of chiral substances, increased accumulation of essential elements in medicinal plants and other processes associated with a possible change in metabolic pathways in the cell and the organism as a whole.</p> <p>The second considered position of the influence of deuterium is associated with the use of deuterated substances–new compounds or obtained by substitution of protium in known protium analogues. The KIE is presented, which is expressed in a decrease in the biotransformation rate as a result of deuteration, it allows predicting a rapid development of the new direction in the development of drugs. Having an identical therapeutic effect, deuterated analogs provide improved pharmacokinetic characteristics, such as reduced toxicity, blocked epimerization of optically active substances, and a change in the mechanisms of biotransformation. The obtained results make it possible to predict the mechanisms of the effect of deuterium on the biochemical transformations of pharmaceutical substances in the organism.</p> ANTON V.

An effective vaccine is needed to prevent further morbidity and mortality. This research aims to identify the challenge in implementing mass vaccination in Indonesia which is related to the efficacy of the COVID-19 vaccine. We retrieve sources from relevant and published articles in Google Scholar, Pubmed, DOAJ and Science Direct of articles up to January 2021. The keywords used for gathering information were listed below. Vaccine efficacy is defined as the proportional reduction of a disease case in a group of vaccinated participants compared with unvaccinated participants. The study of vaccine efficacy is a cohort study that is an important vaccine trial method in the field. It is conducted randomly on a large scale by using a control-placebo. During the trials, the country which used the vaccine needs to maintain and observe the vaccine epidemiology. A trial roadmap is expected to identify the condition of the area epidemiologically. Vaccine efficacy is essential to be observed before implementing the vaccine in society. However, intensive socialization about the advantage of vaccines is mainly needed to prevent irrelevant information in social media about mass vaccination.</p> I.
