Abstract

An amphotericin B composition containing particles of amphotericin B and cholesterol sulfate, in a molar ratio of between about 1:1 to 1:4. The particles, when stored in lyophilized form and reconstituted in an aqueous suspension, have particle sizes predominantly between about 100-400 nm. The composition formed at a molar ratio of about 1:1 amphotericin B:cholesterol sulfate ahs stable particle sizes in an aqueous suspension over a several-day storage period. The composition is significantly less toxic and more effective in treating fungal infection than prior amphotericin B formulations.
