Serotonin Several classes of drugs target the 5-HT system including some antidepressants, antipsychotics, anxiolytics, antiemetics, and antimigraine drugs as well as the psychedelic drugs and empathogens.
Psychoactive drugsThe psychedelic drugs psilocin/psilocybin (magic mushrooms), DMT, mescaline, and LSD mimic the action of serotonin primarily at 5-HT2A receptor. The empathogen MDMA (ecstasy) releases serotonin from synaptic vesicles of neurons.
AntidepressantsThe MAOIs prevent the breakdown of monoamine neurotransmitters (including serotonin), and therefore increase concentrations of the neurotransmitter in the brain. MAOI therapy is associated with many adverse drug reactions, and patients are at risk of hypertensive emergency triggered by foods with high tyramine content and certain drugs.
Some drugs inhibit the re-uptake of serotonin, making it stay in the synapse longer. The tricyclic antidepressants (TCAs) inhibit the re-uptake of both serotonin and norepinephrine. The newer drugs are called selective serotonin re-uptake inhibitors (SSRIs). For more information and side effects of these drugs go to: http://en.wikipedia.org/wiki/SSRIs
