Phenolphthalein tablets

It mainly acts on the colon. After oral administration, it is slowly decomposed under the action of the alkaline intestinal fluid of the small intestine to form soluble sodium salt, which stimulates the nerve plexus in the intestinal wall and directly acts on the intestinal smooth muscle to increase intestinal peristalsis. At the same time, it can inhibit the absorption of water in the intestine, so that water and electrolytes accumulate in the colon, producing a laxative effect. Its effect is mild and rarely causes intestinal spasm.
