Ravuconazole is primarily used as an antifungal agent, particularly effective against a broad spectrum of fungal infections. It is often employed in the treatment of invasive fungal infections, including those caused by Candida and Aspergillus species. Its application is crucial in patients with compromised immune systems, such as those undergoing chemotherapy or organ transplants, where fungal infections can be life-threatening. Additionally, ravuconazole is being investigated for its potential use in treating fungal infections in immunocompromised individuals, including those with HIV/AIDS. Its broad-spectrum activity and favorable pharmacokinetic properties make it a valuable option in antifungal therapy.
