In acute constipation, purgatives that are common to stimulate intestinal peristalsis and evacuation of fluid feces contain salts of

Assertion: In acute constipation, purgative containing magnesium salts are generally used. Reason: The osmotic effect of Mg^(2+) in the intestinal lu- men prevents Water reabsorption from intestine. Mg^(2+) increases the solute concentration in the intestinal lumen because Mg^(2+) is absorbed very slowly
