Trazodone (also sold under the brand names Desyrel, Oleptro, Beneficat, Deprax, Desirel, Molipaxin, Thombran, Trazorel, Trialodine, Trittico, and Mesyrel) is an antidepressant of the serotonin antagonist and reuptake inhibitor (SARI) class. It is a phenylpiperazine compound. Trazodone also has anti-anxiety (anxiolytic) and sleep-inducing (hypnotic) effects. Trazodone has considerably fewer prominent anticholinergic (dry mouth, constipation, tachycardia) and sexual side effects than most of the tricyclic antidepressants (TCAs). Trazodone was originally discovered and developed in Italy in the 1960s by Angelini Research Laboratories as a second-generation antidepressant. It was developed according to the mental pain hypothesis, which was postulated from studying patients and which proposes that major depression is associated with a decreased pain threshold. Trazodone was patented and marketed in many countries all over the world.
