Amphotericin B may be useful in the treatment of American mucocutaneous leishmaniasis, but it is not the drug of choice as primary therapy.

Other Information

Amphotericin B for Injection USP contains amphotericin B, an antifungal polyene antibiotic obtained from a strain of Streptomyces nodosus. Amphotericin B is designated chemically as [1R- (1R*, 3S*, 5R*, 6R*, 9R*, 11R*, 15S*, 16R*, 17R*, 18S*, 19E, 21E, 23E, 25E, 27E, 29E, 31E, 33R*, 35S*, 36R*, 37S*)] -33-[(3-Amino-3, 6-dideoxy-β-D-mannopyranosyl)-oxy]-1,3,5,6,9,11,17,37-octahydroxy-15,16,18-trimethyl-13-oxo-14,39-dioxabicyclo [33.3.1] nonatriaconta-19,21,23,25,27,29,31-heptaene-36-carboxylic acid. Structural formula:

Each vial contains a sterile, nonpyrogenic, lyophilized cake (which may partially reduce to powder following manufacture) providing 50 mg amphotericin B and 41 mg sodium desoxycholate buffered with 20.2 mg sodium phosphates (consisting of mono and dibasic sodium phosphate, phosphoric acid and sodium hydroxide). Crystalline amphotericin B is insoluble in water; therefore, the antibiotic is solubilized by the addition of sodium desoxycholate to form a mixture which provides a colloidal dispersion for intravenous infusion following reconstitution.

At the time of manufacture the air in the vial is replaced by nitrogen.
