Abstract:The purpose of the present study was to formulate and evaluate microemulsion based in situ gel of Acyclovir (ACV) for the vaginal delivery. The solubility of ACV in oils and surfactants and co-surfactant was evaluated to identify the components of the microemulsion. Microemulsion region was determined by using the pseudo-ternary phase diagrams for different formulations. Microemulsion formulation was prepared using Labrafil M1994C as oil phase, Cremophor RH40 as surfactant and Polyethylene glycol 400 and Trans… Show more
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.
