Caspofungin acetate for injection is a sterile, lyophilized product for intravenous (IV) infusion that contains a semisynthetic lipopeptide (echinocandin) compound synthesized from a fermentation product of Glarea lozoyensis. Caspofungin acetate is an echinocandin antifungal that inhibits the synthesis of β(1, 3)-D-glucan, an integral component of the fungal cell wall. Caspofungin acetate is 1-[(4R,5S)-5-[(2-aminoethyl)amino]-N 2 -(10,12-dimethyl-1-oxotetradecyl)-4-hydroxy-L-ornithine]-5-[(3R)-3-hydroxy-L-ornithine] pneumocandin B 0 diacetate (salt). Caspofungin acetate for injection 50 mg vial contains 50 mg of caspofungin equivalent to 55.5 mg of caspofungin acetate. Caspofungin acetate for injection 50 mg vial also contains 39 mg sucrose, 26 mg mannitol, 2 mg glacial acetic acid added as a buffering agent, and sodium hydroxide added as a pH adjuster ingredient. Caspofungin acetate for injection 70 mg vial contains 70 mg of caspofungin equivalent to 77.7 mg of caspofungin acetate. Caspofungin acetate for injection 70 mg vial also contains 54 mg sucrose, 36 mg mannitol, 2.7 mg glacial acetic acid added as a buffering agent, and sodium hydroxide added as a pH adjuster ingredient. Caspofungin acetate is a hygroscopic, white to off-white powder. It is freely soluble in water and methanol, and slightly soluble in ethanol. The pH of a saturated aqueous solution of caspofungin acetate is approximately 6.6. The empirical formula is C 52 H 88 N 10 O 15 •2C 2 H 4 O 2 and the formula weight is 1213.42. The structural formula is: Caspofungin-structure
