Used as an antifungal agent in medical treatments, particularly for invasive fungal infections like candidiasis and aspergillosis. It is administered intravenously to patients with compromised immune systems, such as those undergoing chemotherapy or organ transplants. Effective against strains resistant to other antifungal drugs, it works by inhibiting the synthesis of fungal cell walls. Often prescribed in hospital settings for severe cases where rapid and potent antifungal action is required.
