Pharmaceutical Information
Drug Name Trazodone
Drug ID BADD_D02266
Description Trazodone is triazolopyridine derivative from the serotonin receptor antagonists and reuptake inhibitors (SARIs) class of antidepressants.[A181180] 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.[T646] 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.[T646] Trazodone acts on various receptors, including certain histamine, serotonin, and adrenergic receptors, distinguishing it from other antidepressants that cover a narrow range of neurotransmitters.[T646] It was initially granted FDA approval in 1981.[L3484]
Indications and Usage Trazodone is indicated for the treatment of major depressive disorder (MDD).[L3484] It has been used off-label for adjunct therapy in alcohol dependence, and off-label to treat anxiety and insomnia.[L3484] 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.[A31634]
