GENERIC NAME: trazodone


DRUG CLASS AND MECHANISM: Trazodone is an oral antidepressant drug that affects the chemical messengers (neurotransmitters) within the brain that nerves use to communicate with (stimulate) each other. The major neurotransmitters are acetylcholine, norepinephrine, dopamine and serotonin. Many experts believe that an imbalance among the different neurotransmitters is the cause of depression. Although the exact mechanism of action of trazodone is unknown, it probably improves symptoms of depression by inhibiting the uptake of serotonin by nerves in the brain. This results in more serotonin to stimulate other nerves. Trazodone also may increase directly the action of serotonin. Trazodone is chemically unrelated to the selective serotonin reuptake inhibitors (SSRIs), the tricyclic antidepressants (TCAs) or the monoamine oxidase inhibitors (MAO inhibitors). It is chemically related to nefazodone (Serzone) and shares its actions. Trazodone was approved by the FDA in 1982.

PRESCRIBED FOR: Trazodone is primarily used for the treatment of depression. It is sometimes prescribed as a sedative, and also is used in combination with other drugs for the treatment of panic attacks, aggressive behavior, agoraphobia, and cocaine withdrawal.
