About Lubiprostone

Lubiprostone (trade named Amitiza®) is a local activator of type-2 chloride channels in cells lining the small intestine. Lubiprostone increases fluid secretion into the intestinal tract. This increased fluid level softens the stool, facilitating intestinal motility and bowel movements. Sucampo management believes the type 2 chloride channels also play an important role in the restoration of tight junction complexes and in the recovery of barrier function in the body.

Amitiza® is a registered trademark of Sucampo Pharmaceuticals, Inc.
