Which of the following is true about Trazodone Hydrochloride?

Trazodone Hydrochloride is primarily known as an antidepressant that is commonly prescribed to treat major depressive disorder. It is classified as a serotonin antagonist and reuptake inhibitor (SARI), which helps improve mood by increasing levels of serotonin in the brain. While Trazodone is often used off-label to manage insomnia due to its sedative properties, its main indication is for the treatment of depression. This makes it essential for understanding the proper therapeutic uses of medications within psychiatry and the pharmacological management of mental health conditions.

The other options do not accurately convey the primary use of Trazodone. It is not classified as a controlled substance, which is why the first choice is incorrect. Although it can have anxiolytic effects, it is not specifically indicated for the treatment of anxiety disorders, making the second choice misleading. Lastly, while Trazodone is sometimes utilized to treat insomnia, it is not exclusively used for this purpose, which renders the fourth choice invalid.
