Retardation of Drug Transport through Pig Ear Skin by Liposome-Hydrogel

Abstract

Transport of drug entrapped in a liposome-hydrogel formulation was significantly retarded in an in vitro topical application. Liposomes containing hydrocortisone acetate, a hydrophobic antiinflammatory agent, were prepared by the precipitation method, and the liposomal suspension was mixed with hydrogel into a semisolid gel-type ointment.(omitted)
