RESUMO
In this work we described the development of a new solid oral formulation of ketoconazole, a broad-spectrum antifungal agent that belongs to the class II of Biopharmaceutics Classification System (BCS). The ketoconazole raw material supplier was selected to present a best flow and compactation. In addition we used direct compression and superdisintegrants associated to polyols to enhance the dissolution of the ketoconazole tablets. The dissolution was evaluated based in level C in vivo/in vitro correlation established. The best formulation was obtained with croscarmellose/maltose association that in the accelerated stability assays presented no differences on quality specifications and no drug-excipients interaction by DSC analyses. In this work it was possible to confirm the use of sugar-based excipients as suitable dissolution enhancers in pharmaceutical technology and real processes conditions.
