(-)-Physostigmine is an alkaloid that has been found in Calabar beans and a cholinergic agent.1,2 It inhibits acetylcholinesterase (AChE; IC50 = 0.67 nM).2 (-)-Physostigmine (10 µM) inhibits ChE and increases vagal stimulation-induced ACh output in isolated chicken heart.3 In vivo, (-)-physostigmine (200 and 400 µg/kg) induces decentralized lower eyelid contractions and increases blood pressure in anesthetized rats.4
