Dimemorfan is an antitussive or cough suppressant which acts as a sigma receptor agonist.[1][2] It is an analogue of dextromethorphan and dextrorphan, but lacks significant NMDA receptor antagonistic action and dissociative effects, thereby having reduced abuse potential and adverse effects in comparison.[3]
