Chloride channel activator agent is a locally acting agent that activates chloride channels in the intestine and increases secretion of intestinal fluid that helps in passing of the stool. It is used to treat chronic constipation especially in patients who have little or no benefit from stool softeners or laxatives.
Lubiprostone is used to relieve stomach pain, bloating, and straining and produce softer and more frequent bowel movements in people who have chronic idiopathic constipation (difficult or infrequent passage of stools that lasts for 3 months or longer and is not caused by a disease or a medication). Lubiprostone is also used to treat irritable bowel syndrome with constipation (IBS-C; a condition that causes stomach pain or cramps, bloating, and infrequent or difficult passage of stools) in women who are at least 18 years of age. Lubiprostone is also used to treat constipation caused by certain opioid (narcotic) pain medications in people with chronic (on-going), noncancer pain. Lubiprostone is in a class of medications called laxatives. It works by increasing the amount of fluid that flows into the bowel and allowing the stool to pass more easily.
