Isavuconazonium is a second-generation triazole antifungal approved on March 6, 2015 by the FDA and July 2015 by the EMA for the treatment of adults with invasive aspergillosis and invasive mucormycosis, marketed by Astellas under the brand Cresemba.4 It is the prodrug form of isavuconazole, the active moiety, and it is available in oral and parenteral formulations. Due to low solubility in water of isavuconazole on its own, the isovuconazonium formulation is favorable as it has high solubility in water and allows for intravenous administration. This formulation also avoids the use of a cyclodextrin vehicle for solubilization required for intravenous administration of other antifungals such as voriconazole and posaconazole, eliminating concerns of nephrotoxicity associated with cyclodextrin. Isovuconazonium has excellent oral bioavailability, predictable pharmacokinetics, and a good safety profile, making it a reasonable alternative to its few other competitors on the market.1,2,3
On December 08, 2023, the FDA approved the expanded use of isovuconazonium in pediatric patients for the same indications.7
