Amphotericin B is an antifungal agent used to treat severe or disseminated fungal infections (e.g. invasive aspergillosis, cryptoccoccal meningitis, coccidioidomycosis, mucormycosis, fungemia in neutropenic patients). It comes in several formulations; conventional, cholesteryl sulfate complex, lipid complex, and liposomal. It is usually reserved for serious infection due to significant associated toxicities, though the newer formulations tend to be better tolerated. | |||
