3-Fluorophenmetrazine (also known as 3-FPM, 3-FPH and PAL-593) is a phenylmorpholine-based stimulant and fluorinated analogue of phenmetrazine that has been sold online as a designer drug.[1][2]


Pharmacology[edit]

3-FPM acts as a norepinephrine-dopamine releasing agent with EC50 values of 43 nM and 30 nM, respectively.[3][4] It shows only negligible efficacy as a releaser of serotonin, with an EC50 value of 2558 nM.[3]

Evaluation of its metabolic pathway revealed N‐oxidation, aryl hydroxylation and subsequent O‐methylation, alkyl hydroxylation, oxidation, and degradation of the ethyl‐bridge yielding the O/N‐bis‐dealkylated metabolite, combinations thereof and further glucuronidation or sulfations.[5]

Legality[edit]

Sweden's public health agency suggested to classify 3-Fluorophenmetrazine as illegal narcotic on June 1, 2015.[6] It was finally classified on October 15, 2015.[7]

3-Fluorophenmetrazine is illegal in Switzerland as of December 2015.[8]
