Overview of liposomes

Many of the problems associated with conventional drug therapy may be circum-vented by the use of delivery systems which, in a variety of ways, will optimize drug action. Among the systems being investigated, liposomes hold considerable promise. Versatility in both the structural characteristics of liposomes and their ability to accommodate a wide range of drugs has contributed to the design of appropriate formulations with optimal pharmacological actions. Areas in which such formula-tions have been already applied successfully experimentally or clinically, include cancer chemotherapy, antimicrobial therapy and vaccines
