Homatropine methylbromide is a medication used primarily for its anticholinergic properties. It is a quaternary ammonium compound and a derivative of tropane alkaloids. Homatropine methylbromide is commonly used in the treatment of various gastrointestinal disorders and as a mydriatic agent in ophthalmology.

Pharmacology

Homatropine methylbromide works by blocking the action of acetylcholine on muscarinic receptors in the parasympathetic nervous system. This action leads to a reduction in smooth muscle contractions and glandular secretions, making it effective in treating conditions like peptic ulcers, irritable bowel syndrome, and spastic colon.

Medical Uses

Gastrointestinal Disorders

Homatropine methylbromide is used to alleviate symptoms associated with various gastrointestinal disorders. It helps reduce stomach acid secretion and intestinal motility, providing relief from cramps, spasms, and pain.

Ophthalmology

In ophthalmology, homatropine methylbromide is used as a mydriatic agent to dilate the pupil and paralyze the ciliary muscle for eye examinations and surgical procedures.

Side Effects

Common side effects of homatropine methylbromide include dry mouth, blurred vision, constipation, and urinary retention. Due to its anticholinergic effects, it may also cause tachycardia, confusion, and hallucinations in some patients.

Contraindications

Homatropine methylbromide is contraindicated in patients with glaucoma, myasthenia gravis, and obstructive uropathy. It should be used with caution in patients with cardiovascular disease and hyperthyroidism.
