Fosfluconazole (INNTooltip International Nonproprietary Name) is a water-soluble phosphate prodrug of fluconazole — a triazole antifungal drug used in the treatment and prevention of superficial and systemic fungal infections. The phosphate ester bond is hydrolyzed by the action of a phosphatase — an enzyme that removes a phosphate group from its substrate by hydrolyzing phosphoric acid monoesters into a phosphate ion and a molecule with a free hydroxyl group (dephosphorylation).
