Starches are typically derived from corn or potato. Starches are used in the pharmaceutical industry for a wide variety of reasons, such as an excipient, a tablet and capsule diluent, a tablet and capsule disintegrant, a glidant, or as binder. Disintegrants enable tablets and capsules to break down into smaller fragments (dissolve) so that the drug can be released for absorption. Starches also absorb water rapidly, allowing tablets to disintegrate appropriately.
Starches are also used in the food manufacturing industry for processing, and as food thickeners or stabilizers. There are many other diverse uses for starches in the manufacturing industry. Pregelatinized starch derives primarily from corn, has been cooked and then dried. Instant puddings, pie fillings, soup mixes, salad dressings, candy often contain pregelatinized starch.
Pregelatinized Starch is a kind of physical modified starch, mainly used as pharmaceutical excipient. In pharma excipients applications, it can be used for direct compression, formulations as binder, disintegrant, flow aid and self lubricant.
