Overview
The present invention relates to a polymer based gelatin free capsules made with a combination of polysaccharides isolated from Cassia grandis in combination with corn starch, potato starch and partially hydrolyzed pectin in the ratio of 1.5:1:1:0.5. These polysaccharides are pseudoplastic or exhibit "shear thinning" behavior in solution and show excellent synergy. The degree of pseudoplasticity increases with concentration and molecular weight. Their thickness can be varied and hence due to their multimolecular forming nature the release of the drug inside the capsule may be controlled accordingly. The present invention thus provides an alternative to gelatin which is used for capsule cover and is extracted from animal source whereas this is purely a natural source and is biodegradable and non-toxic.
