Self-microemulsifying drug delivery systems (SMEDDS) represent a possible alternative to traditional oral formulations of lipophilic compounds. This study was designed to compare the oral bioavailability and food-effect of SMEDDS of itraconazole (ITRA-GSMP capsule containing 50 mg itraconazole) to that of the currently marketed formulation (Sporanox capsule containing 100 mg itraconazole). Eight healthy volunteers received Sporanox or ITRA-GSMP capsule in the fasted state or after a high-fat diet on four separate dosing occasions with a 2-week washout period. Blood samples were collected and analyzed. After administration of the ITRA-GSMP capsule, AUC0–24 and Cmax were 1.9- and 2.5-fold higher in the fasted state and 1.5- and 1.3-fold higher in the fed state, respectively, than those of the Sporanox capsule. Moreover, ITRA-GSMP capsules yielded more reproducible blood-time profiles than Sporanox capsules. Food had a marked effect on itraconazole absorption from the Sporanox capsule, whereas the influence was less pronounced for the ITRA-GSMP capsule. Collectively, our data suggest that a new self-microemulsifying formulation may provide an alternative oral formulation for itraconazole with improved oral bioavailability and reduced food-effect.
