Eticyclidine (PCE, CI-400) is a dissociativeanesthetic drug with hallucinogenic effects. It is similar in effects to phencyclidine but is slightly more potent. PCE was developed by Parke-Davis in the 1970s and evaluated for anesthetic potential under the code name CI-400,[2] but research into PCE was not continued after the development of ketamine, a similar drug with more favourable properties.[3] Due to its similarity in effects to PCP, PCE was placed into the Schedule 1 list of illegal drugs in the 1970s, although it was only briefly abused in the 1970s and 1980s and is now little known.
