Description | Homatropine Methylbromide is the methyl bromide salt of homatropine, a synthetic tertiary amine alkaloid with antimuscarinic properties. |
Targets&IC50 | mAChR (SHR-E):170.3 nM, mAChR (WKY-E):162.5 nM |
In vitro | Homatropine [14C]methylbromide administered rectally in rats achieved higher and quicker peak plasma concentrations compared to other routes. After 12 hours, 28% of the [14C] was excreted in the urine, with 56% remaining in the colon. Unlabeled homatropine methylbromide, delivered via a rectal suppository in anesthetized rats, rapidly blocked the effects of the vagus nerve on heart rate and of intravenous acetylcholine on blood pressure. A dose of 20 mg/kg homatropine increased the survival rate to 30% in rats poisoned with diazinon, with death occurring between 4 to 12 minutes, whereas a 10 mg/kg dose was ineffective in preventing mortality. |
In vivo | When combined with hexamethonium, 20 μM Homatropine yields only a dose ratio of 95.0 in guinea pig atria. In contrast, 20 μM Homatropine alone produces a dose ratio of 259 in guinea pig atria. |
