The invention provides an itraconazole composition comprising itraconazole dispersed in a hydrophilic polymer, and, optionally, a surfactant, having a dissolution at 15 minutes between 10 and 40%, at 30 minutes between 60 and 95%, at 45 minutes more than 80%, as measured using the type II paddle method at 100 rpm according to the US Pharmacopoeia, in a dissolution medium comprised of 1000 ml HCl 0.1N. The invention also provides a composition of itraconazole comprising an inert carrier covered with at least one layer containing said itraconazole in a micronized form having a size less than 5 µm, dispersed in a hydrophilic polymer and, optionally, a surfactant, wherein the weight ratio polymer:itraconazole is equal to or higher than 1.9.The invention provides also a process for preparing said composition and a specific itraconazole solution useful in said process.
