Formulation and evaluation of liquisolid compacts of itraconazole to enhance its oral bioavailability.

Formulate and evaluate liquisolid compacts of Itraconazole, a biopharmaceutical classification system class II drug, which has poor bioavailability. PEG 600 was used as a nonvolatile solvent, Alfacel PH 200 as a carrier and Aerosil 200 as a coating material. The Itraconazole solution upon mixing with a carrier and coating material resulted in a dry powder, which was compressed into tablets. The optimized formulation exhibited a significantly higher drug dissolution (90.73% in 90 min) compared with conventional tablets and marketed capsules. The antifungal activity was retained in the formulation. Higher values of C and AUC of the formulation compared with the plain drug indicated enhancement in oral bioavailability. The formulation was stable at room temperature as well as in accelerated conditions.
