Homatropine Methylbromide is muscarinic AChR antagonist, inhibits endothelial and smooth muscle muscarinic receptors of WKY-E and SHR-E with IC50 of 162.5 nM and 170.3 nM, respectively.target: mAChRIC 50: WKY-E(162.5 nM), SHR-E(170.4nM )In vitro: Homatropine (20 μM) alone produces a dose ratio of 259 in atrium from guinea-pigs. Homatropine (20 μM) produces a dose ratio of only 95.0 when combined with hexamethonium in atrium from guinea-pigs.In vivo: : Pre-treatment with homatropine (20 m
Homatropine methylbromide is an organic bromide salt and an azabicycloalkane. It has a role as a muscarinic antagonist, an anti-ulcer drug and an antispasmodic drug.|Homatropine methylbromide is a quaternary ammonium muscarinic acetylcholine receptor antagonist belonging to the group of medicines called anti-muscarinics. Homatropine is used to treat duodenal or stomach ulcers or intestine problems. It can be used together with antacids or other medicine in the treatment of peptic ulcer.
