DESIGN AND EVALUATION OF FAST DISSOLVING TABLETS OF CARVEDILOL USING SUBLIMATION TECHNIQUEAbstract
The purpose of the study was to design and evaluate fast dissolving carvedilol tablets using β-Cyclodextrin and superdisintegrants adopting sublimation technique. Tablets were prepared by direct compression method. Tablets were evaluated for their physico chemical properties, wetting time, disintegration, in-vitro release and stability studies. SEM analysis was carried out to determine the surface characteristics of solid dispersions. Precompressional studies revealed good micromeritic properties of powder blend for direct compression. The hardness (3.9-4.3 kg/cm2), friability (0.35-0.51), drug content (96.58-99.43 %) and disintegration time (44.05-66.21 sec) of fast dissolving tablets were found uniform and reproducible. Dissolution of tablets was directly proportional to the superdisintegrants concentration. Selected tablet (F1) was found superior than any other formulations with respect to disintegration and dissolution time.
