Amphotericin B

Amphotericin B (Fungilin, Fungizone, Abelcet, AmBisome, Fungisome, Amphocil, Amphotec) is an antifungal drug often used intravenously for systemic fungal infections.[1] It is the only effective treatment for some infections.[1]

Common side effects may include: a reaction which may include fever, headaches and low blood pressure among other symptoms rapidly after it is given, and kidney problems.[1] Allergic symptoms including anaphylaxis may occur.[1]

It was originally extracted from Streptomyces nodosus, a filamentous bacterium, in 1955, at the Squibb Institute for Medical Research. Its name originates from the chemical's amphoteric properties. It is on the World Health Organization's List of Essential Medicines, a list of the most important medications needed in a basic health system.[2] It is of the polyene class. Currently, the drug is available as plain amphotericin B, as a cholesteryl sulfate complex (ABCD), as a lipid complex (ABLC), and as a liposomal formulation (LAmB). The latter formulations have been developed to improve tolerability, but may show considerably different pharmacokinetic characteristics compared to plain amphotericin B.
