Mefenorex

Mefenorex is an amphetamine derivative with a relatively mild psychostimulant profile. Developed in the 1960s, it was used throughout the 1970s as an appetite suppressant for treating obesity. Mefenorex is a prodrug of amphetamine; upon ingestion, the compound will begin to metabolize into, as well as promote the production of, the active metabolites levoamphetamine and dextroamphetamine. Multiple sources have noted the substance as exerting "mild stimulant effects.... relatively little abuse potential."
