Used primarily to treat chronic constipation, especially in cases where laxatives have not been effective. It works by stimulating the movement of the intestines through selective activation of serotonin 5-HT4 receptors, enhancing gastrointestinal motility. Commonly prescribed for women with irritable bowel syndrome with constipation (IBS-C) and other motility disorders. Its high selectivity reduces the risk of cardiac side effects, making it a safer option for long-term use.
