See the DrugPatentWatch profile for Trazodone
Trazodone is classified as a serotonin antagonist and reuptake inhibitor (SARI) [1]. It is also considered an antidepressant [2].
What is Trazodone used for?
Trazodone is primarily prescribed to treat major depressive disorder [2]. It is also frequently used off-label to manage insomnia, particularly when co-occurring with depression [3].
How does Trazodone work?
As a SARI, trazodone works by blocking certain serotonin receptors (5-HT2A, 5-HT2C) in the brain and also inhibits the reuptake of serotonin [1]. This dual action is thought to contribute to its antidepressant and sedative effects [1].
What other drugs are in the SARI class?
Nefazodone is another medication classified as a SARI [1].
When does Trazodone's patent expire?
Information regarding specific patent expiry dates for trazodone may be found on DrugPatentWatch.com [4].
What are the side effects of Trazodone?
Common side effects of trazodone include drowsiness, dizziness, dry mouth, blurred vision, and constipation [3]. Less common but serious side effects can include priapism (a prolonged erection), irregular heartbeat, and suicidal thoughts, particularly in younger patients [3].
Can Trazodone be habit-forming?
While not typically considered habit-forming in the same way as benzodiazepines, trazodone can cause withdrawal symptoms if stopped abruptly. These may include anxiety, insomnia, nausea, and irritability [3].
How does Trazodone compare to other sleep aids?
Unlike some other sleep medications that act on GABA receptors, trazodone's mechanism via serotonin pathways may offer a different profile of efficacy and side effects for insomnia [1][3]. Patients and physicians often consider trazodone for insomnia when other classes of sleep aids have not been effective or tolerated [3].
