Direct Compression

The aim of present work was to develop fast dissolving tablets of Valsartan by direct compression method using different binders such as acacia, sucrose, starch, gelatin, hydroxypropyl methylcellulose (HPMC) H7509, and Polyvinyl-pyrrolidone (PVP). During the compression of tablets, binders keep the composition of these fast dissolving tablets together. The right selection of binder or combination of these is essential to maintain the integrity and stability of the tablet. The prepared tablets were evaluated for parameters such as hardness, friability, drug content, weight variation, wetting time, water absorption ratio, in-vitro disintegration time, in vitro dissolution studies and stability studies. The study reveals that formulations prepared by direct compression (F5) exhibits better dissolution (90.57%) with lowest disintegration time (40 seconds) containing sucrose as binding agent.
