In its pharmacology, MDA is a serotonin–norepinephrine–dopamine releasing agent (SNDRA). Abstract. Encountering a novel controlled-substance analog (designer drug) has become a distinct possibility for all forensic drug laboratories. 3,4-Methylenedioxyamphetamine (MDA) in particular is a receptive parent compound for the molecular modifications which produce such homologs and analogs.LSD is an agonist of 5-HT2A receptors, and the empathogen MDMA (ecstasy) releases 5-HT from synaptic vesicles of neurons and rather specifically targets the 5-HT1A receptor. MDA (3,4 methylenedioxyamphetamine) also named ‘psychedelic amphetamine’ enters 5-HT neurons via the reuptake pump and affects 5-HT2 receptor sites.
