What is PRO-BANTHINE used for

The name of your medicine is PRO-BANTHINE.

The active ingredient is called propantheline bromide.

Propantheline bromide belongs to a group of medicines called the anticholinergics.

Anticholinergics are used to reduce both gastric acid and other secretions in the stomach, and to reduce cramps or spasms in the muscles of your stomach, intestine and urinary tract.

PRO-BANTHINE works by stopping some of the actions of a naturally occurring substance called acetylcholine which then reduces:

  • the amount of acid produced by your stomach
  • cramps or spasms in the muscles of your stomach, intestine and urinary tract
  • the amount of sweat produced by your body

PRO-BANTHINE is used to treat a number of different conditions:

It reduces:

  • ulcers in the stomach (gastric ulcers) and in the first part of the intestine (duodenal ulcers) with the assistance of other medicines
  • urinary problems caused by nerves or muscles that control the bladder
  • excessive sweating

Your doctor may have prescribed this medicine for another condition.

Ask your doctor if you have any questions about why PRO-BANTHINE has been prescribed for you.

PRO-BANTHINE tablets are only available with a doctor’s prescription.

This medicine is not recommended for use in children.
