Phospholipid particles encapsulating polyene antibiotics for the treatment of systemic fungal infections.

摘要

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 .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 antifungal antibiotic to treat systemic fungal infections.
