Itraconazole is a triazole antifungal agent with a broad spectrum of activity. It is well tolerated and highly efficacious, particularly because its main metabolite, hydroxy‐itraconazole, also has considerable antifungal activity. Two new formulations of itraconazole, an oral solution and an intravenous formulation, have recently been developed, which combine lipophilic itraconazole with cyclodextrin. These formulations have improved the solubility of itraconazole, leading to enhanced absorption and bioavailability compared with the original capsule formulation, without having an impact on the tolerability profile of itraconazole. The oral solution and intravenous formulations of itraconazole produce consistent plasma concentrations and are ideal for the treatment of systemic fungal infections in a wide range of patient populations. The additional flexibility offered by the different routes of administration means that itraconazole treatment can be specifically tailored for use in all patients, including children and those requiring intensive care.
