Rimcazole is an antagonist[1] of the sigma receptor.[2] Sigma receptors are thought to be involved in the drug psychosis that can be induced by some drugs such as PCP and cocaine, and rimcazole was originally researched as a potential antipsychotic with a different mechanism of action to traditional antipsychotic drugs. Trials proved inconclusive and rimcazole was not pursued for this application, but other sigma antagonists continue to be researched for a variety of potential applications.[3]


Rimcazole has been shown to reduce the effects of cocaine,[4] and analogues of rimcazole have been shown to be highly effective at blocking the convulsions caused by cocaine overdose in animal models.[5]
