Summary The specificity of fenfluramine as a pharmacological probe of the serotonin system has been questioned, since animal studies with high dose 1-fenfluramine show increases in striatal levels of the dopamine metabolite homo-vanillic acid. To test the specificity of fenfluramine in humans with clinical doses, we compared plasma homovanillic acid (pHVA) concentration in healthy volunteers after administration of fenfluramine (60 mg) and placebo. There were no significant effects on pHVA, which supports previous findings that at doses used in pharmacological challenge paradigms, the effect of fenfluramine on the dopamine system is insufficient to alter measures of its change. |
