What Is Trazodone?

Trazodone is a tetracyclic atypical antidepressant, which can selectively antagonize the reuptake of serotonin (5-HT) and has a weak effect of preventing norepinephrine (NA) reuptake. However, it has no effect on dopamine (DA), histamine, and acetylcholine, nor does it inhibit the activity of monoamine oxidase inhibitor (MAO) in the brain. In addition, this product also has an antagonistic effect on 5-HT2A receptor or 5-HT2C receptor. The 5-HT2 receptor located in the presynaptic membrane belongs to the self-receptor, and plays a negative feedback regulation effect on the release of 5-HT; this product also suppresses negative feedback regulation and increases the release of 5-HT to achieve an antidepressant effect. This product also has a central sedative effect and a slight muscle relaxation effect, but has no anti-spasmodic and central excitatory effects, can improve sleep, significantly shorten the sleep latency of patients with depression, prolong overall sleep time, and improve sleep quality.

Not for use with MAOIs. SSRIs such as fluoxetine and paroxetine can reduce the clearance of this product and can also cause 5-HT syndrome with it. This product inhibits the metabolism of carbamazepine and phenytoin in the liver and increases the blood concentration of the latter. This product inhibits the antihypertensive effect of central antihypertensive drugs (such as clonidine). Combined with chlorpromazine, triflurazine, perphenazine, mesodazine, thioridazine and other drugs, it can produce a synergistic hypotensive effect and cause hypotension. Combined with droperidol, it can increase the cardiotoxicity of the latter.
