Homatropine Hydrobromide

개요Homatropine is an anticholinergic agent. It reduces acetylcholine-induced contractions of isolated goat detrusor muscle strips when used at a concentration of 5 μM. Homatropine (1 μM) inhibits acetylcholine- or methacholine-induced contraction of isolated rat anococcygeus muscle. It inhibits serotonin- or thrombin-induced platelet aggregation in isolated sheep platelet-rich plasma (IC50s = 4.3 and 100 μM, respectively). Topical ophthalmic administration of homatropine induces partial mydriasis in Angora goats.

용도Homatropine is an anticholinergic agent. Homatropine acts as an inhibitor of the muscarinic acetylcholine receptors. Homatropine is used in eye drops as a cycloplegic and as a mydriatic, to dilate the pupil.

일반 설명Homatropine hydrobromide,1 H,5 H-tropan-3 -ol mandelate (ester) hydrobromide(Homatrocel), occurs as white crystals or as awhite, crystalline powder that is affected by light. It is solublein water (1:6) and alcohol (1:40), less soluble in chloroform(1:420), and insoluble in ether.Solutions are incompatible with alkaline substances,which precipitate the free base, and with the commonreagents that precipitate alkaloids. As with atropine, solutionsare sterilized best by filtration through a bacteriologicalfilter.
