Significant medical advances in the treatment and management of immunocompromised patients are currently leading to an ever-increasing incidence of invasive fungal infections (IFI). Due to the limited antifungal treatment options, the management of IFI remains a major challenge. The triazole antifungal drug isavuconazole (ISV) shows a broader spectrum of activity against Mucorales isolates and represents another therapeutic option for difficult-to-treat IFI. ISV is a broad-spectrum triazole antifungal II. generation, which is primarily intended for the treatment of invasive aspergillosis and mucormycosis, but in the future it also represents a promising therapeutic option for the treatment of other, rare IFIs (cryptococcosis, infections caused by dimorphic fungi). The article summarizes the basic knowledge and provides a brief overview of the pharmacodynamics, pharmacokinetics, mechanism of action, metabolism, indications, and dosage of isavuconazole in clinical practice. It also includes a brief analysis of selected clinical trials (SECURE, ACTIVE, VITAL) and recommendations of individual international societies.
