Amphotericin B remains the treatment of choice for systemic fungal infections, but amphotericin B is toxic and is often not effective in treating disseminated infections. Liposome intercalation of amphotericin B reduces the toxicity associated with amphotericin B and targets reticuloendothelial tissues most heavily involved in fungal infections. The targeted delivery and reduced toxicity of liposomal amphotericin B improves the therapeutic index of amphotericin B. Although liposomes have been shown to effectively treat a variety of experimental and human fungal infections, the optimal composition of liposomal amphotericin has not been established. Vesicle type, lipid content, size, and conditions of storage markedly affect toxicity, therapeutic efficacy, and tissue distribution. In vitro studies have been poor predictors of in vivo efficacy and toxicity. Animal models can be used to evaluate in vivo the optimal liposome preparation. Liposomal amphotericin B appears to be an improved means of amphotericin B delivery and may improve the treatment of patients with systemic fungal infections.
