Mephedrone, a synthetic cathinone, produces different effects on body temperature and brain chemistry than MDMA (ecstasy) in rats. MDMA caused sustained decreases in rectal and tail temperature, while mephedrone caused only a transient drop in rectal temperature and a prolonged decrease in tail temperature. In contrast, cathinone and methcathinone raised rectal temperature. MDMA reduced serotonin and certain metabolites in several brain regions, whereas cathinone and methcathinone increased the dopamine metabolite homovanillic acid and serotonin metabolite 5-HIAA in the striatum. Mephedrone increased plasma noradrenaline, which was blocked by certain receptor antagonists. The adverse effects of cathinones in humans cannot be extrapolated from MDMA data.
