Pergelatinous starch, which is obtained by heat treatment of starch dispersion in water and then drying the resulting gel, is widely used as a binder in tablets and capsules. In this case, the starch gel acts as a binder to hold the powder particles.

This also causes uniform distribution and controlled release of active pharmaceutical ingredients. When this mixture is compressed under optimum pressure, stable tablets are formed. Pergelatinous starch is used at a concentration of 3 to 20% by weight of granules or tablets. The usual concentration is between 5 and 10% by weight.
