Etoxadrol is a dissociative anaesthetic drug which has been found to be an NMDA antagonist and produces similar effects to PCP in animals.[1][2] Etoxadrol, along with another related drug dexoxadrol, were developed as analgesics for use in humans, but development was discontinued after patients reported side effects such as nightmares and hallucinations.[3][4]
