4-Fluoroethylphenidate (commonly known as 4F-EPH) is a novel synthetic stimulant of the substituted phenethylamine and piperidine classes that produces long-lasting euphoric and stimulating effects associated with potent monoamine reuptake inhibitors when administered. It is a closely related structural analog of the commonly prescribed ADHD drug methylphenidate (known by the brand-names Ritalin and Concerta) as well as a designer drug analog ethylphenidate. Based on its similarities to other memebers of this class, it is speculated to exert its activity as some form of double or triple monoamine reuptake inhibitor.
