Formulation and In Vitro Evaluation of Niosomal Gel for The Topical Administration of Losartan Potassium.

This study aims to develop and test a topical drug delivery system for antihypertensive activity using Losartan potassium-loaded niosomes. The niosomes were created using the traditional ether injection approach, with four formulations made using cholesterol as the lipid and varying quantities of surfactants such as span 80 and span 60. The different formulations underwent testing for FTIR, particle size, zeta potential, drug content, entrapment efficiency, and in vitro release. FTIR analysis revealed that the medication was incompatible with excipients. The study concludes by highlighting current obstacles and future possibilities for the development of niosomes as effective vehicles. Overall, this analysis provides insight into the potential of niosomes in medication delivery and encourages further research in this field. [ABSTRACT FROM AUTHOR]
