4-Fluoromethylphenidate (commonly known as 4F-MPH) is a novel synthetic stimulant of the phenidate class that produces long-lasting euphoriant, and stimulating effects when administered. It is a closely related structural analog of the commonly prescribed ADHD drug methylphenidate (known by the brand-names Ritalin and Concerta).
The two substances are believed to have very similar pharmacological mechanisms as monoamine reuptake inhibitors but have been reported to display distinctive subjective effects, with 4F-MPH being considered significantly more euphoric and recreational.
