Trazodone Hydrochloride

Overview

Basic Info

SummaryTrazodone, a small molecule drug, targets the serotonin transporter and acts as a serotonin reuptake inhibitor. Although approved for treating several conditions, including major depressive disorder, diabetic neuropathies, sleep initiation and maintenance disorders, and premature ejaculation, the drug's mechanism of action remains elusive. Angelini Pharma was the first to approve the drug for use in December 1981. By increasing serotonin levels in the brain, Trazodone hydrochloride reduces symptoms of depression and improves mood. Additionally, the drug has sedative properties that make it effective in treating sleep disorders. However, Trazodone may produce unwanted side effects such as dizziness, drowsiness, and dry mouth and interact with other medications, resulting in unwanted consequences.
