Abstract
Formulations consisting of phospholipid small unilamellar particles encapsulating polyene antifungal antibiotics and methods for using such compositions to treat systemic fungal infections are described. In a preferred embodiment, the particles are in the form of vesicles which comprise a polyene antifungal antibiotic, preferably amphotericin B and/or nystatin, egg phosphatidylcholine and cholesterol, preferably in the molar ratio of about 0.2 (AMB):2(PL):1(CHOL). These vesicles may also have an amine modified surface. The vesicles are suspended in a low ionic strength saccharide/tris solution at a pH of from about 6.0 to about 8.0 and may be administered to deliver the anti-fungal antibiotic to treat systemic fungal infections.
