Eticyclidine (PCE, CI-400) is a dissociative anesthetic 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,[1] but research into PCE was not continued after the development of ketamine, a similar drug with more favourable properties.[2] PCE is slightly more potent than PCP and has similar effects,[medical citation needed] but its unpleasant taste and tendency to cause nausea made it less accepted by users.[citation needed] 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.
