“Officials with the FDA have approved tenapanor (Ibsrela, Ardelyx), a 50 mg, twice-daily oral medication for the treatment of irritable bowel syndrome with constipation (IBS-C) in adults, according to a press release.

Tenapanor, a novel treatment, is a minimally-absorbed small molecule that acts locally in the gastrointestinal (GI) tract to inhibit the sodium-hydrogen exchanger NHE3. Through this mechanism, treatment results in increased bowel movements and decreased abdominal pain for patients, according to Ardelyx.
