Caspofungin (INN;[1][4] brand name Cancidas) is a lipopeptide antifungal drug from Merck & Co., Inc..[5] It is a member of a class of antifungals termed the echinocandins.[medical citation needed] It works by inhibiting the enzyme (1→3)-β-D-glucan synthase and thereby disturbing the integrity of the fungal cell wall.[medical citation needed]

Caspofungin was the first inhibitor of fungal (1→3)-β-D-glucan synthesis to be approved by the United States Food and Drug Administration.[6] Caspofungin is administered intravenously.[2] It is on the World Health Organization's List of Essential Medicines.[7]
