(International Journal of Applied Pharmaceutics, 2021) Dey, Biplab Kumar; Myrsing, Efficiency; Amin, Ruhul; Alam, Faruk; Rahman, Mizanur; Gogoi, Pal; Afroz, Tahmina
Objective: Shortages of medicinal products are complex global problems. Drug shortages remain a significant public health issue. Global shortages of medical products have a potential effect on patient health and total healthcare costs. Countries worldwide, especially those affected by Coronavirus disease 2019 (COVID-19), is experiencing a rapid increase in drug shortage, which causes several complications for physicians, health care provider, patients, health institutes and health regulatory bodies. Methods: To carry out the study of shortages, several efforts have been taken by the regulators and industries. Prominent amongst these include FDA's research the needs and the reforms made in the regulations about shortages. We also searched for electronic databases (PubMed, Science direct, Web of Science) using the terms (COVID-19 and shortage) or (medicine and COVID-19) for articles in periods of 2019 to 2021. Results: On assessment based on the report, the number of shortage drugs in 2020 is 835; Anesthesia drugs are highest during the COVID-19 outbreak data indicate the number of shortages is 143 in USA. It was found that generic products were mostly in short supply, with antimicrobial agents (63%) topping the list of therapeutic categories of medicines with interrupted supply, followed by oncology medicines (47%) and then anesthetic agents (38%) during COVID-19 pandemic. Conclusion: Many steps have been taken to reduce the impact of a shortage of health care. Agencies like the United States Food and Drug Administration (US FDA) and European Medicines Agency (EMA) has established guidelines and works with manufacturers and other partners to help prevent shortages. This article aims to the analysis the root cause of medicinal product shortages, their effects on the patient outcome, medication error, which occurs due to the substitution safe and effective therapies with alternative treatments, identify possible solutions and policies established to manage medicinal product shortages.

Ondansetron tablets that are directly compressed using crospovidone and croscarmellose as a synthetic super disintegrant are the subject of this investigation. A central composite, response surface, randomly quadratic, nonblock (version 13.0.9.0) 32 factorial design is used to optimize the formulation (two-factor three-level). To make things even more complicated, nine different formulation batches (designated as F1-F9) were created. There were three levels of crospovidone and croscarmellose (+1, 0, -1). In addition to that, pre- and postcompressional parameters were evaluated, and all evaluated parameters were found to be within acceptable range. Among all postcompressional parameter dispersion and disintegration time, in vitro drug release experiments (to quantify the amount of medication released from the tablet) and their percentage prediction error were shown to have a significant influence on three dependent variables. Various pre- and postcompression characteristics of each active component were tested in vitro. Bulk density, tap density, angle of repose, Carr's index, and the Hausner ratio were all included in this analysis, as were many others. This tablet's hardness and friability were also assessed along with its dimension and weight variations. Additional stability studies may be conducted using the best batch of the product. For this study, we utilised the Design-Expert software to select the formulation F6, which had dispersion times of 17.67 ± 0.03 seconds, disintegration times of 120.12 ± 0.55 seconds, and percentage drug release measurements of 99.25 ± 0.36 within 30 minutes. Predicted values and experimental data had a strong correlation. Fast dissolving pills of ondansetron hydrochloride may be created by compressing the tablets directly.
Multidimensional Chromatography and Its Applications in Food Products, Biological Samples and Toxin Products

Food, drugs, dyes, extracts, and minerals are all made up of complex elements, and utilizing unidimensional chromatography to separate them is inefficient and insensitive. This has sparked the invention of several linked chromatography methods, each of them with distinct separation principles and affinity for the analyte of interest. Multidimensional chromatography consists of the combination of multiple chromatography techniques, with great benefits at the level of efficiency, peak capacity, precision, and accuracy of the analysis, while reducing the time required for the analysis. Various coupled chromatography techniques have recently emerged, including liquid chromatography–gas chromatography (LC–GC), gas chromatography–gas chromatography (GC–GC), liquid chromatography–liquid chromatography (LC–LC), GCMS–MS, LCMS–MS, supercritical fluid techniques with chromatography techniques, and electro-driven multidimensional separation techniques. In this paper, the different coupled chromatography techniques will be discussed, along with their wide spectrum of applications for food, flavor, and environmental analysis, as well as their usefulness for the pharmaceutical, color, and dyes industries.
