Trazodone

Trazodone is triazolopyridine derivative from the serotonin receptor antagonists and reuptake inhibitors (SARIs) class of antidepressants. It is used in adults and has been shown to be comparable in efficacy to other drugs such as tricyclic antidepressants (TCAs), selective serotonin reuptake inhibitors (SSRIs), and serotonin-norepinephrine receptor inhibitor (SNRIs) in the treatment of depression. A unique feature of this drug is that it does not promote the anxiety symptoms, sexual symptoms, or insomnia, which are commonly associated with SSRI and SNRI therapy. Trazodone acts on various receptors, including certain histamine, serotonin, and adrenergic receptors, distinguishing it from other antidepressants that cover a narrow range of neurotransmitters. It was initially granted FDA approval in 1981.

Trazodone is indicated for the treatment of major depressive disorder (MDD). It has been used off-label for adjunct therapy in alcohol dependence, and off-label to treat anxiety and insomnia. It may also be used off-label to treat symptoms of dementia, Alzheimer’s disease, schizophrenia, eating disorders, and fibromyalgia due to its effects on various neurotransmitter receptors.
