title: Preparation of microencapsulated liposomes, II. Systems containing nylon-gelatin and nylon-gelatin-acacia walling material.
abstract: Liposome suspension was encapsulated and isolated in nylon-gelatin and nylon-gelatin-acacia walled microcapsules. The resulting liposomal microcapsules could be stored in the dry state as a free-flowing powder. Liposomes remained intact after the microencapsulation, and encapsulation efficiency was greater than 90 per cent. The release of drug from microcapsules was retarded in the presence of drug-loaded liposomes.
