What is linaclotide (Linzess)? What is linaclotide used for?
Linaclotide is an oral medication for the treatment of constipation. It is the first in a new class of drugs called guanylate cyclase-C agonists. It is used for relieving symptoms of irritable bowel syndrome (IBS) with constipation and for treating chronic constipation of unknown cause (idiopathic constipation).
Linaclotide works locally in the intestine (it is not absorbed into the body) to increase bowel movements and reduce pain. Linaclotide's effects are due to an increase in the production of a chemical called cyclic guanosine monophosphate which increases fluid secretion into the intestine and reduces the sensitivity of pain-sensing nerves. The FDA approved linaclotide in August 2012.

Irritable Bowel Syndrome (IBS)
Irritable bowel syndrome (IBS) is a GI (gastrointestinal) disorder with signs and symptoms that include abdominal pain, bloating, increased gas (flatulence), abdominal cramping, diarrhea, constipation, and food intolerance.Two new tests are now available that may help diagnose irritable bowel syndrome with diarrhea and constipation (IBS-M) irritable bowel syndrome with diarrhea (IBS-D), and irritable bowel syndrome with constipation (IBS-C). Treatment for IBS includes diet changes, medications, and other lifestyle changes to manage symptoms.
Constipation is defined medically as fewer than three stools per week and severe constipation as less than one stool per week. Constipation usually is caused by the slow movement of stool through the colon. There are many causes of constipation including medications, poor bowel habits, low-fiber diets, laxative abuse, and hormonal disorders, and diseases primarily of other parts of the body that also affect the colon.
IBS-D (Irritable Bowel Syndrome with Diarrhea)
IBS-D or irritable bowel syndrome with diarrhea refers to IBS with diarrhea. Symptoms of IBS-D include intestinal gas (flatulence), loose stools, frequent stools, abdominal pain, diarrhea, and nausea. New non-FDA approved IBS tests may help diagnose IBS and IBS-D. Treatment of IBS-D is geared to toward managing symptoms with diet, medication, and lifestyle changes.
IBS Triggers (Prevention)
Irritable bowel syndrome (IBS) is a functional disease that can affect the quality of those who suffer from this condition. People with IBS can make lifestyle changes that may modify or control the number and severity of episodes. Certain foods, medications, and hormone levels may trigger IBS episodes, for example fatty foods, dairy products, eating foods in large quantities, foods that contain high levels of sorbitol, foods that produce intestinal gas (broccoli, onions, cabbage, and beans), chocolate, caffeine, physiological stress, some antibiotics, some antidepressants, medicine with sorbitol, and menstrual pain. Exercise, diet, and other lifestyle changes can decrease IBS flares, and prevent the number and severity of IBS episodes of diarrhea and constipation.
