Starch can be used in both granulation formulation techniques. In dry granulation techniques where active ingredient is hygroscopic and is difficult to dry after wet binding, maize starch has proved to be an efficient dry binder. Since starch is partial cold water soluble, starch functions exceptionally well in tablet manufactured by wet granulation applications and performs dual functions of both a disintegrant and a binder. In capsule filling processes, starch functions as an effective binder improving the uniformity of the capsule fill as well as forming a stable capsule plug.
Starch is used as an excipient in solid oral dosages.
