Natural disintegrant are widely used in the development of mouth dissolving tablets and other formulation because of easily available, low cost and rapide onset of action in the mouth dissolving tablet and it enhance the bioavalaibility and disintegration properties as comparaed to synthetic polymer. But aftrer freeze drying and spray drying technique the properties of dsintegrant is increases because its improve the bulkiness and flow property of a powder such as bulk density, tapped density, angle of repose, hausner raio, carrs index etc. by freeze drying the powder are dried and thereby increase the dissolution and disintegration time and highly porous powder is produced by spray drying technique.
