title: Liposomal polyene antibiotics.
abstract: Polyene antibiotics (i.e., amphotericin B and nystatin) have been incorporated into lipid-based delivery systems to decrease their toxicity and enhance their therapeutic index, the most common being liposomes. This chapter describes the protocols for preparing liposomal amphotericin B and determining the efficacy and toxicity of the formulations in animals. Furthermore, methods for determining the pharmacokinetics and drug distribution after administration of amphotericin B in lipid-based delivery systems are discussed. Procedures for comparing the toxicity of different amphotericin B formulations in cell culture studies are also elucidated.
