PG - 95-8 AB - This study examined the [3H]5-HT-releasing properties of 3,4-methylenedioxymethamphetamine (MDMA) and related agents, all of which cause significant release of [3H]5-HT from rat brain synaptosomes. 5-HT uptake blockers dose dependently block MDMA-induced [3H]5-HT release. The EC50s of the uptake drugs in blocking MDMA-induced release correlate with their affinity for the 5-HT uptake site labeled by [3H]paroxetine (r = 0.98; P less than 0.01). These data demonstrate that the 5-HT uptake carrier plays a significant role in the release of 5-HT induced by MDMA and related agents.
