Solubility Enhancement of Carvedilol Using Liquisolid Compact Technique

A novel liquisolid compact technique was used for soulbility enahncement of poorly water soluble drug carvedilol (CAR). CAR was dissolved in water miscible non volatile solvent and then adsorbed on a solid carrier which was later compacted with other excipient into a tablet. The tablets were characterized with respect to hardness, friability, disintegration and in-vitro dissolution profile. Effect of storage conditions on dissolution profile was also studied. DSC and XRD studies were done to confirm the physical state of CAR in the formulation.
