Voriconazole (VRZ) is a second-generation triazole antifungal agent active against many species of Aspergillus and Candida and acts by inhibiting ergosterol synthesis. VRZ has less nephrotoxicity and less infusion-related toxicity than that of Amphotericin B. Oral and parental formulation have similar pharmacokinetics and thus oral formulation shortens the duration of hospital stay. It is overall well tolerated but has significant drug interactions.
