N-Ethylpentylone (β-keto-ethylbenzodioxolylpentanamine,βk-ethyl-K,βk-EBDP,ephylone) is asubstituted cathinone andstimulant drug which was developed in the 1960s.[2][3]
It has been reported as a noveldesigner drug in several countries including the United Kingdom,[4] South Africa,[5] New Zealand,[6] the United States,[7] and Australia.[8] In 2018,N-ethylpentylone was the most common drug of the cathinone class to be identified inDrug Enforcement Administration seizures.[9]
In vivo studies in mice demonstrated that acute intraperitoneal administration of N-ethylpentylone induced anincrease in locomotor activity,anxiolytic effects but also anaggressive behaviour as well as social exploration deficits. Repeated exposure to N-ethylpentylone induced hyperthermia, anorexia and rewarding effects. During withdrawal after repeated administration, depression-like symptoms, hyperlocomotion, and a decrease of social exploration were observed.[16][17]
