Eseroline

Eseroline is a drug which acts as an opioid agonist.[1] It is a metabolite of the acetylcholinesterase inhibitor physostigmine but unlike physostigmine, the acetylcholinesterase inhibition produced by eseroline is weak and easily reversible,[2][3] and it produces fairly potent analgesic effects mediated through the μ-opioid receptor.[4] This mixture of activities gives eseroline an unusual pharmacological profile,[5][6] although its uses are limited by side effects such as respiratory depression[7] and neurotoxicity.[8]
