A number of starch modifications are used in pharmaceutical applications. Pregelatinized or compressible starch has been chemically or mechanically processed to rupture all or part of the granules in water. It is then dried to yield an excipient material suitable for direct-compression formulations. Sterilizable maize starch contains magnesium oxide (not greater than 2.2%) and has been chemically or physically treated to prevent gelatinization on exposure to moisture or steam sterilization. Soluble starch results when potato or maize starch has been chemically treated to destroy the gelatinizing ability of starch. 

Table I Pharmacopeial specifications for sterilizable maize starch.

Sterilizable maize starch is a chemically or physically modified corn (maize) starch that does not gelatinize on exposure to moisture or steam sterilization. Sterilizable maize starch is primarily used as a lubricant for examination and surgeons gloves although because of safety concerns unlubricated gloves are now generally recommended. It is also used as a vehicle for medicated dusting powders. 

Sterilizable maize starch occurs as an odorless, white, free-flowing powder. Particles may be rounded or polyhedral in shape.
