Active ingredients in A07BC

Active Ingredient Description

Attapulgite is a magnesium aluminium phyllosilicate which occurs in a type of clay soil common to the Southeastern United States. It physically binds to acids and toxic substances in the stomach and digestive tract. For that reason, it has often been used in antidiarrheal medications.


Diosmectite is a natural aluminomagnesium silicate clay with a lamellar, non-fibrous crystalline structure that gives it strong adsorbent properties. Diosmectite has demonstrated efficacy in the treatment of acute watery diarrhoea in children.


Pectin is a structural acidic heteropolysaccharide contained in the primary and middle lamella cell walls of terrestrial plants. The characteristic structure of pectin is a linear chain of alpha(1-4)linked D-galacturonic acid that forms the pectin-backbone, a homogalacturonan.
