Use in medicine and pharmacology
Montmorillonite clay is widely used in medicine and pharmacology.
For internal use, montmorillonite is effective in the treatment of irritable bowel syndrome. It is also used for the prevention of aflatoxicosis, and in the treatment of constipation. Also, a modified version inhibits intestinal absorption of cholesterol (nanotechnology research) , and absorbs uric acid. It is used in agriculture to improve growth performance of piglets and fish. It ameliorates hyperthyroidism of rats and mice. Montmorillonite is also used in other related research.
Montmorillonite is proven to be effective in use as an adsorptive of heavy metals, toxins, and hazardous chemicals.
Antibacterial effects of montmorillonite are well demonstrated.
For external use, montmorillonite has also shown its effectiveness. It has also shown itself useful for tissue engineering.
Montmorillonite is widely used in pharmacology for a variety of application, such as stabilization of suspensions and emulsions, viscosizing, adhesion to the skin, and tablet making . It is also used as drug carrier, or as part of a drug delivery system, such as for controlled drug release; including for gene delivery, and for drug targeting to specific tissues. It is also used for stability enhancement in drug and nutrient application. There are also other similar uses.
Montmorillonite is also used in the production of pharmaceuticals, e. g. as a catalyst.
