Eticyclidine

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,^[2] but research into PCE was not continued after the development of ketamine, a similar drug with more favourable properties.^[3] 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}
