Historically used to help manage symptoms of irritable bowel syndrome (IBS), functional digestive disorders, and associated abdominal cramping and discomfort. May also be used for other conditions as determined by a healthcare provider.
The belladonna alkaloids (atropine and related compounds) work as antispasmodics by blocking acetylcholine receptors in the smooth muscle of the gastrointestinal tract, helping to reduce spasms and cramping. Butabarbital, a barbiturate, provides mild sedative and anxiolytic effects that may help with anxiety related to GI symptoms.
This medication contains a barbiturate, which carries risks of dependence and drowsiness. Patients should avoid driving or operating machinery until they understand how the medication affects them. Not recommended during pregnancy, for elderly patients, or for those with certain medical conditions including glaucoma, urinary retention, or severe heart disease. Should be used under medical supervision only.
