In present investigation liquisolid compact technique is investigated as a tool for enhanced dissolution of poorly water-soluble drug Ketoconazole. The liquisolid tablets were formulated with liquid medications, namely Propylene Glycol (PG) drug concentrations, 60% w/w, 70% w/w and 80% w/w. Avicel pH102 was used as a carrier material, Aerosil 200 as a coating material and Sodium starch glycollate as a super-disintegrant. Quality control tests, such as uniformity of tablet weight, uniformity of drug content, tablet hardness, friability test, disintegration and dissolution tests were performed to evaluate prepared tablets. For further confirmation of results the liquisolid compacts were evaluated by XRD and FTIR studies to prove that, solubility of Ketoconazole has been increased by liquisolid compact technique. From the results obtained, it was be speculated that such systems exhibit enhanced drug release profiles due to increased wetting properties and surface of drug available for dissolution. As liquisolid compacts demonstrated significantly higher drug release rates, in PG as compared to directly compressible tablets and conventional wet granulation, we lead to conclusion that it could be a promising strategy in improving the dissolution of poor water soluble drugs and formulating immediate release solid dosage forms.
