Ibogamine is an anti-convulsant, anti-addictive CNS stimulant alkaloid found in Tabernanthe iboga and Crepe Jasmine (Tabernaemontana divaricata).[1][2][3][4] Basic research related to how addiction affects the brain has used this chemical.[5]

Ibogamine persistently reduced the self-administration of cocaine and morphine in rats.[6] The same study found that ibogamine (40 mg/kg) and coronaridine (40 mg/kg) did not produce "any tremor effects in rats that differ significantly from saline control". While the related alkaloids ibogaine (20–40 mg/kg), harmaline (10–40 mg/kg) and desethylcoronaridine (10–40 mg/kg) were "obviously tremorgenic".[6]


It blocks nicotinic acetylcholine receptor at neuromuscular junction. It also blocks kappa receptor,N-nethyl-D-asparate receptor. It also has effect on serotonin sites.[7] It also inhibits acetycholinestearase and butrylcholinestearase[8]
