Abstract

This invention relates to a starch based tablet disintegrant useful at low addition levels and providing equally effective properties in water and physiological fluids. The starches are characterized by their low solubility in cold water, high swelling power and labile birefringence in the dry state, which rapidly disappears upon addition of water. The preferred starches are inhibited then processed to remove a portion of the granular structure.
