N-Ethylpentedrone (also known as ñ-ethylaminopentiophenone, ñ-EAPP, ñ-ethylamino-valerophenone, N-ethylnorpentedrone, Ethylnorpentedrone, Norpentedrone, Ethylpentedrone, and NEP) is a chemical compound and stimulant of the substituted cathinone class. Since the mid-2010s, NEP has been sold online as a designer drug. It is the N-ethyl analog of pentedrone. N-Ethylpentedrone acts as a norepinephrine-dopamine reuptake inhibitor (NDRI) without inducing monoamine release.
NEP is illegal in Japan and China, and is classified as a '"potentially harmful substance"', thus, controlled, but not banned in Sweden and UK.
