The substituted amphetamines 3,4-methylenedioxymethamphetamine, methamphetamine, p-chloroamphetamine and fenfluramine induce 5-hydroxytryptamine release via a common mechanism blocked by fluoxetine and cocaine

Substituted amphetamines MDMA, methamphetamine, PCA, and fenfluramine all release serotonin from nerve endings through a shared mechanism. PCA and fenfluramine are the most potent, MDMA is less potent, and methamphetamine is much less potent. Combining two drugs at half-effective concentrations does not increase release beyond either drug alone. The serotonin reuptake blockers fluoxetine and cocaine inhibit release from all four drugs equally. However, at low concentrations that block reuptake, these amphetamines do not reduce release caused by higher concentrations, indicating their uptake blockade differs from that of fluoxetine or cocaine.
