What is Phenolphthalein? 

 

Phenolphthalein irritating laxatives, the main role in the large intestine. After oral administration in the intestinal alkaline environment to form soluble sodium salt, stimulate the plexus wall plexus, a direct role in the intestinal smooth muscle, so that peristalsis increased. At the same time phenolphthalein and inhibit intestinal absorption of water, so that water and electrolyte accumulation in the colon, resulting laxation effect. The role of strength and intestinal size of alkaline, and its role in mild, rarely cause intestinal spasm.
