Amphotericin B is an antifungal agent, generally reserved for very serious infections (disseminated disease, invasive aspergillosis, cryptoccoccal meningitis, coccidioidomycosis, infection/sepsis in immunocompromised hosts) due to significant associated toxicities. It comes in several formulations; conventional, cholesteryl sulfate complex, lipid complex, and liposomal. The newer formulations tend to have fewer adverse effects. | |||
