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 mg/kg) was comparable with atropine (10 mg/kg) in preventing lethality in this rat model of acute OC poisoning. All rats pre-treated with normal saline, atropine 5 mg/kg, and homatropine 10 mg/kg died. Survival in the homatropine (20 mg/kg) and atropine (10 mg/kg) groups was 30% and 40% respectively.
