MYCAMINE is a sterile, lyophilized product for intravenous (IV) infusion that contains micafungin sodium. Micafungin sodium is a semisynthetic lipopeptide (echinocandin) synthesized by a chemical modification of a fermentation product of Coleophoma empetri F-11899. Micafungin inhibits the synthesis of 1,3-beta-D-glucan, an integral component of the fungal cell wall. Each single-dose vial contains 50 mg micafungin (equivalent to 50.86 mg micafungin sodium) or 100 mg micafungin (equivalent to 101.73 mg micafungin sodium), 200 mg lactose monohydrate, with citric acid and/or sodium hydroxide (used for pH adjustment). MYCAMINE must be diluted with 0.9% Sodium Chloride Injection, USP, or 5% Dextrose Injection, USP [see Dosage and Administration ( 2 )] . Following reconstitution with 0.9% Sodium Chloride Injection, USP, the resulting pH of the solution is between 5-7. Micafungin sodium is chemically designated as: Pneumocandin A0,1-[(4 R ,5 R )-4,5-dihydroxy- N 2 -[4-[5-[4-(pentyloxy) phenyl]-3-isoxazolyl]benzoyl]-L-ornithine]-4-[(4 S )-4-hydroxy-4-[4-hydroxy-3-(sulfooxy)phenyl]-L-threonine]-, monosodium salt. The chemical structure of micafungin sodium is: The empirical/molecular formula is C 56 H 70 N 9 NaO 23 S and the formula weight is 1292.26. Micafungin sodium is a light-sensitive, hygroscopic white powder that is freely soluble in water, isotonic sodium chloride solution, N,N-dimethylformamide and dimethylsulfoxide, slightly soluble in methyl alcohol, and practically insoluble in acetonitrile, ethyl alcohol (95%), acetone, diethyl ether and n-hexane.
