This article reviews the pharmacology of antidepressants, particularly focusing on those that act acutely by blocking the reuptake of norepinephrine (ne) and/or serotonin (5-ht). Such drugs have a very wide range of potencies, measured in vitro, to inhibit the reuptake of these biogenic amines.
Related biogenic amines, especially na, 5-ht and, to a lesser extent, da ( dopamine), antidepressants that inhibit the reuptake and metabolism of these amines.
Most available antidepressants enhance neurotransmission of biogenic amines, mainly norepinephrine and serotonin, to a lesser extent dopamine. Once released from specialized vesicles at the presynaptic nerve terminal, neurotransmitters enter the synaptic cleft and bind to respective receptors at the postsynaptic cell membrane, thus modulating.
Biogenic amine neurotransmitters such as norepinephrine, dopamine, and serotonin are inactivated at the synapse.
Thus, the “biogenic amine hypothesis of depression” postulates that de- pression is amines. The tricyclin appear to be antidepressants due to their inhibition.

The biogenic amine transporters (bats) regulate endogenous neurotransmitter concentrations and are targets for a broad range of therapeutic agents including selective serotonin reuptake inhibitors (ssris), serotonin-noradrenaline reuptake inhibitors (snris) and tricyclic antidepressants (tcas).
Monoamine oxidase (mao) is an enzyme found in nerves and other tissues. Maois exert their effect in relieving depression by inhibiting this enzyme to break down the biogenic amines ne, dopamine, and 5-ht. Now used rarely because of their strict and specific dietary regimen to prevent toxicity.

Until recently the tricyclic antidepressants were thought to act by inhibiting uptake of the biogenic amines noradrenaline and 5-hydroxytryptamine (serotonin). But this did not explain why the depressed mood takes several weeks to respond, whereas biogenic amine uptake is inhibited soon after treatment begins.
The introduction of two tricyclic compounds (iprindole and mianserin) that are reported to have antidepressant properties but to be relatively devoid of effects on central amine neurotransmitter systems has raised questions about the amine hypothesis of depression and about the mechanism of action of tricyclics in general.
Then, in the early 1950s, researchers discovered a correlation between depression and drugs that increased and decreased monoamines and the biogenic amine.
