Background In the global health emergency caused by COVID-19, multiple experts have mandated the use of hand sanitizers as a safety measure from COVID-19. The sale of hand sanitizers has increased many folds. Therefore, when there is such large use of hand sanitizers, it becomes extremely important to study and understand hand sanitizers in a comprehensive manner. Main body of the abstract This article starts with the importance of sanitizers as a defence mechanism that is employed by the hand to fight against the coronavirus. This article provides information about history, types, composition, various dosage forms, and marketed formulations of hand sanitizers. The article sheds a detailed light on industrial production techniques for hand sanitizers and also outlines new innovative techniques that were employed by the industry to mass produce hand sanitizers in the wake of the pandemic. The article further dives into a comparison between hand sanitizers and soaps so as to give pros and cons of the use of soap against the use of hand sanitizers. One of the aims of the article is to study the side effects of sanitizers so as to develop a cautious approach while using hand sanitizers and therefore a comprehensive list of side effects of the use of hand sanitizers is given. Conclusion The review article finds that hand sanitizers are extremely efficient in fight the virus but along with it, it brings along arrange of risks which are outlined in the article.
Neomycin sulphate is official in IP 2018, USP 2004 and BP 2003; which includes Microbial assay (Cylinder Plate assay) for the estimation therefore chemical derivatization of Neomycin Sulphate is done using 1-Fluoro-2, 4-Dinitrobenzene (DNFB); also known as Sanger’s reagent, to make it detectable by UV with good accuracy and precision. A fixed dose combination of Neomycin Sulphate, Clobetasol Propionate and Chlorocresol (preservative) in cream formulation is used to treat different types of Skin infections. The literature review reveals that methods like UV, HPLC, HPTLC, GC-MS etc. have been reported for Neomycin Sulphate and Clobetasol Propionate individually and along with other drugs. But no reported method found in combination for Neomycin sulphate and Clobetasol propionate. A simple, accurate, precise and economical UV spectrophotometric i.e. Area Under Curve Method (AUC) was developed. All the dilutions of drugs were prepared in Methanol: Acetonitrile (50:50). Area under curve was integrated in the wavelength range of 235.0- 245.0 nm, 252.0-262.0 nm and 223.0-233.0 nm for CSP, NMS and CCS respectively. The AUC method for Clobetasol Propionate (CSP), Neomycin Sulphate (NMS) and Chlorocresol (CCS) was found to be linear over the range of 0.8-1.2 μg/ml, 8.0-12.0 μg/ml and 1.6-2.4 μg/ml respectively. The result of analysis was analysed and validated statistically and recovery study was found within range of 98-102%. The % RSD was not more than 2.0 % which indicates good precision. All the validation parameters were carried out according to ICH Q2 (R1) guidelines.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
