Ethybenztropine (Ponalid) is a muscarinic receptor blocker. Ethybenztropine is an anticholinergic and antihistaminergic agent[1].

Synonyms	Ponalide Etybenzatropine //BP VK-738 Etibenzatropina UK-738 ethybenztropine Ethylbenztropine Ethylbenatropine 8-Azabicyclo[3.2.1]octane, 3-(diphenylmethoxy)-8-ethyl-, (3-endo)

Description	Ethybenztropine (Ponalid) is a muscarinic receptor blocker. Ethybenztropine is an anticholinergic and antihistaminergic agent[1].

Target	Muscarinic Receptor[1]
In Vitro	Ethybenztropine (10 μM) inhibits the uptake of 3H-DA in neostriatal slices.
In Vivo	Ethybenztropine (25 μg, microinjected into mesencephalic NRM) blocks the hypertherrnic response of carbachol microinjection into nucleus raphe median (NRM) of rabbits[1]. Ethybenztropine (30-60 μg/kg, administered by the fourth ventricle) is effective in preventing arrhythmias in dogs[2]. Ethybenztropine (50 mg/kg, i.p.) reduces the catecholamines accumulation in rats[3]. Animal Model: Dogs with cardiac arrhythmias[2] Dosage: 30-60 μg/kg Administration: Administered by the fourth ventricle Result: Produced slight hypotension (never exceeding a fall of 25 mm Hg) and slight sinus tachycardia. Converted arrhythmias to sinus rhythms.
