Pharmacological properties

bisacodyl causes a laxative effect, which is manifested by softening or thinning the stool. the mechanism of the laxative effect is due to an increase in the penetration of water into the intestinal cavity and a decrease in its absorption, as well as an acceleration of intestinal motility.

An important place in the mechanism of action is the splitting of bisacodyl in the alkaline contents of the intestine, which leads to the formation of substances that irritate the receptors of the intestinal mucosa. This leads to stimulation of intestinal motility.

Pharmacokinetics Intestinal and bacterial enzymes quickly convert bisacodyl into its active metabolite. Only 5% of the oral dose is absorbed into the systemic circulation, transformed in the liver and excreted in the urine, bile in the form of an inactive metabolite (glucuronides).
