Amphotericin B use in children: conventional and lipid-based formulations

Invasive fungal infections (IFIs) are important causes of morbidity and mortality in immunocompromised children. The increased incidence and high mortality rates associated with IFIs has led to development of novel antifungal agents to expand the breadth and effectiveness of treatment options available to clinicians. Since its initial approval in 1958, conventional amphotericin B deoxycholate had been considered the standard in treatment for IFIs. However, because of the dose-limiting toxicity of conventional amphotericin B deoxycholate, lipid formulations of amphotericin have been developed to potentially improve outcomes and mitigate the adverse effects associated with antifungal therapy. While less frequently employed today as prophylaxis (given the expanded availability of safer alternatives), amphotericin B is still considered a treatment option in select cases of severe or life-threatening IFIs. This article reviews the clinical use of amphotericin B for the prevention and treatment of IFIs.
