Feedback:
Lubiprostone is a locally acting chloride channel activator that increases the secretion of a chloride-rich intestinal fluid without changing sodium or potassium levels. Increasing the intestinal fluid leads to increased motility. It does not add bulk, irritate the inner lining, or innervate the bowel.
