What is Linzess (linaclotide)?

Linzess is a prescription medication that is manufactured through a partnership between Allergan and Ironwood Pharmaceuticals, Inc. It was initially approved by the United States Food and Drug Administration (FDA) in 2012 to treat:

Linzess is classified as a guanylate cyclase-C agonist (GC-C agonist). It binds to the GC-C receptor within the intestinal epithelium, which increases the fluid in your intestines. This moves food and waste through your gastrointestinal (GI) transit to increase bowel movements and relieve chronic constipation. In animal studies, Linzess also reduced stomach pain.
