Background and Date of Approval
Plecanatide is a medication approved for treating certain gastrointestinal disorders. It works by mimicking a naturally occurring peptide in the body that regulates fluid balance in the intestines, promoting bowel movements. The U.S. Food and Drug Administration (FDA) approved this drug on January 19, 2017, based on clinical trials demonstrating its efficacy and safety in treating chronic idiopathic constipation (CIC) and irritable bowel syndrome with constipation (IBS-C). The pivotal clinical trials included thousands of patients and showed significant improvement in bowel movement frequency and stool consistency compared to placebo.
Mechanism of Action of undefined
This medication functions as a guanylate cyclase-C (GC-C) agonist, activating receptors on the intestinal lining to increase fluid secretion. This process softens stool and facilitates bowel movements. Additionally, it helps reduce abdominal discomfort and bloating by improving intestinal motility. Unlike stimulant laxatives, it works naturally with the body's fluid regulation mechanisms, making it a targeted treatment for specific types of constipation.
Uses of undefined
FDA-approved uses of this drug include:
- Chronic idiopathic constipation (CIC) – Long-term constipation without an identifiable cause
- Irritable bowel syndrome with constipation (IBS-C) – A functional bowel disorder characterised by abdominal pain and constipation
undefined Drug administaration and Dosage available
Plecanatide is available as an oral tablet and is typically prescribed in a 3 mg once-daily dose, which can be taken with or without food. The tablet should be swallowed whole and not crushed, split, or chewed to ensure proper release of the medication. It is approved for use in adults aged 18 years and older and is not recommended for children. The drug should be taken at the same time each day for consistent results. If a dose is missed, it should be taken as soon as remembered, but double dosing should be avoided.
