A serotonergic substance, medication, or receptor protein is one that affects neurotransmission pathways that involve serotonin, as follows: Serotonergic drugs Serotonin receptor agonists
Serotonin (/ ˌ s ɛr ə ˈ t oʊ n ɪ n, ˌ s ɪər ə-/) [6] [7] [8] or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter.Its biological function is complex, touching on diverse functions including mood, cognition, reward, learning, memory, and numerous physiological processes such as vomiting and vasoconstriction.
Concomitant use of SSRIs or SNRIs for depression with a triptan for migraine does not appear to heighten the risk of the serotonin syndrome. [120] Taking monoamine oxidase inhibitors (MAOIs) in combination with SSRIs can be fatal, since MAOIs disrupt monoamine oxidase , an enzyme which is needed to break down serotonin and other neurotransmitters.
This in turn leads to increased extracellular concentrations of serotonin and, therefore, an increase in serotonergic neurotransmission. It is a type of monoamine reuptake inhibitor (MRI); other types of MRIs include dopamine reuptake inhibitors and norepinephrine reuptake inhibitors.
The 5-HT 1B receptor as an example of a metabotropic serotonin receptor. Its crystallographic structure in ribbon representation. 5-HT receptors, 5-hydroxytryptamine receptors, or serotonin receptors, are a group of G protein-coupled receptor and ligand-gated ion channels found in the central and peripheral nervous systems.
Serotonin syndrome (SS) is a group of symptoms that may occur with the use of certain serotonergic medications or drugs. [1] The symptoms can range from mild to severe, and are potentially fatal.
Serotonergic-noradrenergic antidepressant drugs may have a modest efficacy advantage compared to SSRIs in treating major depressive disorder (MDD), [43] but are slightly less well tolerated. [44] Further research is needed to examine the possible differences of efficacy in specific MDD sub-populations or for specific MDD symptoms, between these ...
Noradrenergic and specific serotonergic antidepressants (NaSSAs) are a class of psychiatric drugs used primarily as antidepressants. [1] They act by antagonizing the α 2 -adrenergic receptor and certain serotonin receptors such as 5-HT 2A and 5-HT 2C , [ 1 ] but also 5-HT 3 , [ 1 ] 5-HT 6 , and/or 5-HT 7 in some cases.
