It has been used in laboratory experiments to study how addiction affects the brain.[2]

Tabernanthine persistently reduced the self-administration of cocaine and morphine in rats.[3]

Pharmacology

edit

It is kappa opioid agonist (Ki = 0.15 μM) and NMDA receptor (Ki = 10.5 μM) antagonist.[4][5] Compared to ibogaine, it binds weakly to σ1 and σ2 receptor.[5]
