CAS 51-56-9: Homatropine hydrobromide

Description:Homatropine hydrobromide is a synthetic anticholinergic agent primarily used in ophthalmology as a mydriatic and cycloplegic agent. It is a quaternary ammonium compound derived from tropic acid and is structurally related to atropine. The substance appears as a white to off-white crystalline powder, which is soluble in water and alcohol. Its mechanism of action involves blocking the action of acetylcholine at muscarinic receptors, leading to pupil dilation and paralysis of the ciliary muscle, which is useful for diagnostic procedures in the eye. Homatropine hydrobromide is typically administered as eye drops, and its effects can last for several hours. While generally well-tolerated, potential side effects may include increased intraocular pressure, dry mouth, and blurred vision. Due to its anticholinergic properties, caution is advised in patients with certain medical conditions, such as glaucoma or urinary retention. Overall, homatropine hydrobromide is an important tool in clinical practice for facilitating eye examinations.
