Starch and Pregelatinized Starch (as excipients)
Starch and pregelatinized starch are used primarily as binders to improve tablet durability and integrity. Both are derived from corn. Pregelatinized starch is partially hydrolyzed and dried to make it flow better during tableting. It also has superior binding characteristics.
Starch and pregelatinized starch are also used as disintegrants. After ingestion, these starch granules swell in the fluid environment of the stomach and force the tablet to break apart.
