Homatropine Bromide_product_DataBase

Bioactivity	Homatropine Bromide is an orally active muscarinic acetylcholine receptor antagonist and can be used as an anticholinergic agent[1].
Invitro	Homatropine (20 μM) alone produces a dose ratio of 259 in atrium from guinea-pigs, and produces a dose ratio of only 95.0 when combined with Hexamethonium Bromide (HY-B0569) in atrium from guinea-pigs[1].Homatropine has affinities for muscarinic receptors in stomach (pA2 = 7.13) and for those in atria mediating force (pA2 = 7.21) and rate (pA2 = 7.07) responses[2].
In Vivo	Homatropine methylbromide (9 mm x 5 mm conical suppository) causes prompt blockade of the effects of vagal stimulation on pulse rate and of intravenous acetylcholine on blood pressure in rats[3]. Animal Model:
