Posaconazole is a triazole antifungal agent approved for the prevention and treatment of invasive fungal infections caused by Aspergillus and Candida species in immunocompromised patients. It is used both for prophylaxis in patients at high risk for fungal infections and for treatment of ongoing invasive infections. Approved by FDA and widely used in clinical practice.
Pharmacokinetics
Healthy adult volunteers, single-dose pharmacokinetics following 200 mg intravenous infusion over 30 minutes.
