It may help symptoms of cramping and abdominal/stomach pain by decreasing
stomach acid, and slowing the intestines. It is commonly prescribed in combination with
chlordiazepoxide (a benzodiazepine derivative) using the brand name
Normaxin.
Uses
Peptic ulcer disease
Used in fixed combination with chlordiazepoxide as adjunctive therapy in the treatment of peptic ulcer disease; however, no conclusive data that antimuscarinics aid in the healing, decrease the rate of recurrence, or prevent complications of peptic ulcers.
With the advent of more effective therapies for the treatment of peptic ulcer disease, antimuscarinics have only limited usefulness in this condition.
GI motility disturbances
Used in fixed combination with chlordiazepoxide in the treatment of functional GI motility disturbances (e.g., irritable bowel syndrome).
Has limited efficacy in treatment of GI motility disturbance and should only be used if other measures (e.g., diet, sedation, counseling, amelioration of environmental factors) have been of little or no benefit.
Acute enterocolitis
Used in fixed combination with
chlordiazepoxide in the treatment of acute
enterocolitis. However,
antimuscarinics should be used with extreme caution in patients with diarrhea or
ulcerative colitis.

muscarinic acetylcholine receptors on
