4-Fluoromethylphenidate (also known as 4-FMPH and 4F-MPH) is a stimulant drug that acts as a higher potency dopamine reuptake inhibitor than the closely related methylphenidate.[1][2][3]

4-Fluoromethylphenidate was studied further along with other analogues of (±)-threo-methylphenidate (TMP) to assess their potential as anti-cocaine medications. 4F-MPH was reported as having an ED50 mg/kg of 0.26 (0.18–0.36), regarding its efficacy as a substitute for cocaine, and a relative potency of 3.33 compared to methylphenidate for the same purpose.[4]

Another study found that in the threo-isomers of methylphenidate, the meta- and para-substituted compounds with electron-withdrawing substituents tended to have increased binding potency. Compounds containing fluorine, chlorine, bromine and methyl groups were reported to be more potent than methylphenidate. 4F-MPH was reported as having the following values: [3H]WIN 35428 binding of 35.0 ± 3.0 (2) and [3H]dopamine 142 ± 2.0 (2).[5]

Legal status[edit]

4-Fluoromethylphenidate is a Schedule I controlled substance in the US state Alabama.[6] As of 5 May 2017, 4-fluoromethylphenidate is a controlled substance in Canada.[7]
