Abstract The effects of the 5-HT2 receptor agonists 1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI) and 5-methoxy-N,N-dimethyltryptamine (5-MeODMT) on 3,4-methylenedioxymethamphetamine (MDMA)-induced dopamine release and 5-HT depletion in the striatum were studied. The MDMA-induced increase in the extracellular concentration of dopamine in the striatum was enhanced significantly in rats treated with either DOI (2 mg/kg, ip.) or 5-MeODMT (15 mg/kg, ip.), as assessed using in vivo microdialysis. Neither DOI nor 5-MeODMT alone altered the extracellular concentration of dopamine in the striatum. The striatal concentration of 5-HT was decreased, but not significantly, 7 days following a single administration of MDMA (10 mg/kg, sc.). However, 7 days following the concomitant treatment with DOI and MDMA the striatal concentration of 5-HT was significantly less than that in rats treated with MDMA alone or the vehicle-treated controls. It is concluded that activation of 5-HT2 receptors is an important determinant of the acute increase in extracellular dopamine and, consequently, the long-term depletion of brain 5-HT produced by MDMA.
