Trazodone, sold under many brand names, [1] is an antidepressant medication [20] used to treat major depressive disorder, anxiety disorders, and insomnia. [20] It is a phenylpiperazine compound of the serotonin antagonist and reuptake inhibitor (SARI) class.
Antidepressants that have dual mechanisms of action inhibit the reuptake of both serotonin and norepinephrine and, in some cases, inhibit with weak effect the reuptake of dopamine. [10] Antidepressants affect variable neuronal receptors such as muscarinic cholinergic, α 1 - and α 2-adrenergic, H 1-histaminergic, and sodium channels in the ...
This is a complete list of clinically approved prescription antidepressants throughout the world, as well as clinically approved prescription drugs used to augment antidepressants or mood stabilizers, by pharmacological and/or structural classification.
While an increase in antidepressant use occurred before the FDA advisory, there were abrupt and sustained declines in use — ranging from 20% to 50% — after the warnings.
The precise mechanism for its antidepressant and anxiolytic effects is not known. [10] Common side effects include dry mouth, nausea, feeling tired, dizziness, agitation, sexual problems, and increased sweating. [10] Severe side effects include an increased risk of suicide, serotonin syndrome, mania, and liver problems. [10]
The relative risk of intracranial bleeding is increased, but the absolute risk is very low. [105] SSRIs are known to cause platelet dysfunction. [ 106 ] [ 107 ] This risk is greater in those who are also on anticoagulants, antiplatelet agents and NSAIDs (nonsteroidal anti-inflammatory drugs), as well as with the co-existence of underlying ...
However, increased side effects and abuse potential are potential concerns of these agents relative to their SSRI and SNRI counterparts. The SNDRIs are similar to non-selective monoamine oxidase inhibitors (MAOIs) such as phenelzine and tranylcypromine in that they increase the action of all three of the major monoamine neurotransmitters.
Desvenlafaxine is a synthetic form of the isolated major active metabolite of venlafaxine, and is categorized as a serotonin-norepinephrine reuptake inhibitor (SNRI). When most normal metabolizers take venlafaxine, approximately 70% of the dose is metabolized into desvenlafaxine, so the effects of the two drugs are expected to be very similar. [18]
