Indications & Uses

Pharmacology

Propantheline Bromide works in two ways. First, it acts as an anticholinergic, which means it blocks the receptors that acetylcholine normally binds to, so it reduces the effect of acetylcholine. Acetylcholine is a chemical released from nerves that tells muscles to contract. Second, it has a direct relaxing effect on smooth muscle. This is why it is classed as an antimuscarinic with antispasmodic properties.

By blocking acetylcholine, Propantheline slows down movement in the gut and reduces the amount of stomach acid produced. It also helps control excessive secretions from the throat, windpipe and airways. Secretions from the pancreas, along with sweat and saliva, are reduced as well.

Dosage Reference

Reference Information Only

Dosages shown are general references from official sources. Always consult your doctor or pharmacist for personalized dosing.

Adults:

The usual starting adult dosage of Propantheline Bromide is 75 mg a day, taken as one tablet (15 mg) 30 minutes before each meal, three times daily, plus two tablets at bedtime. The dosage should then be adjusted according to the patient's individual response and tolerance, but the maximum daily dosage should not exceed 120 mg.

Pediatric use: safety and effectiveness in pediatric patients have not been established.

Side Effects

Side effects of propantheline bromide are usually dose-related and generally clear up once treatment is stopped. Varying degrees of dry mouth, dry skin and dilated pupils (mydriasis) may occur. Other reported side effects include difficulty passing urine (urinary retention), nausea, vomiting, constipation, headache, nervousness and mental confusion.

Cautions & Contraindications

Warnings & Precautions

Propantheline should be used with caution in elderly patients and in anyone with autonomic neuropathy, liver or kidney disease, an overactive thyroid (hyperthyroidism), coronary heart disease, congestive heart failure, a rapid or irregular heartbeat (cardiac tachyarrhythmia), or high blood pressure, because anticholinergic medicines can make these conditions worse.

Contraindications

Propantheline Bromide should not be given to patients with any of the following: Hypersensitivity to Propantheline bromide or other anticholinergic agents; glaucoma; obstructive disease of the gastrointestinal tract (pyloroduodenal stenosis, paralytic ileus etc.); obstructive uropathy (e.g. prostatic hypertrophy); intestinal atony of the elderly; and myasthenia gravis.

Pregnancy & Breastfeeding

Propantheline bromide falls under pregnancy category C. No animal reproduction studies have been carried out with this drug, so it should only be used during pregnancy if the need is clearly established. Whether it passes into breast milk is also unknown; since many medicines do pass into breast milk, it should be used with caution in breastfeeding mothers. As with other anticholinergic medicines, it may also reduce milk supply.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.

Overdose

In an overdose of Propantheline Bromide, the usual side effects get stronger, starting with nausea and vomiting. After that come CNS disturbances, which range from restlessness and excitement to psychotic behaviour. Circulatory changes follow (flushing, a fall in blood pressure and circulatory failure), and then respiratory failure and paralysis.

⚠️ In an emergency call 999 or go to the nearest hospital emergency department.

Storage

Store Propantheline Bromide at or below 30°C. Keep it away from light, and keep it out of the reach of children.
