Used to treat chronic idiopathic constipation and irritable bowel syndrome with constipation (IBS-C) in adults. It works by increasing fluid secretion into the intestine, which helps stimulate bowel movements and improve stool consistency. The drug acts locally in the gut with minimal absorption into the bloodstream, reducing the risk of systemic side effects. It is taken orally, usually once daily, and offers a targeted approach for patients needing relief from constipation-related symptoms.
