- Mechanism
- Curator reviewed · 1 reference
Potassium bitartrate is a carbon dioxide-releasing laxative that works by forming carbon dioxide gas, which creates a mechanical distension against the intestinal wall and induces bowel contractions. Rectal suppositories of carbon dioxide-releasing type of laxative were demonstrated to be useful and safe in the treatment of patients at risk for electrolyte disorders such as the elderly or patients with renal or cardiovascular disorders.
