Overview of liposomes

Many of the problems associated with conventional drug therapy may be circumvented 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 formulations have been already applied successfully experimentally or clinically, include cancer chemotherapy, antimicrobial therapy and vaccines.
