Area of Science:

• Pharmacology
• Clinical Pharmacy
• Psychiatry

Background:

• Trazodone hydrochloride is a triazolopyridine antidepressant.
• Its chemistry, pharmacokinetics, pharmacology, and clinical use are reviewed.

Purpose of the Study:

• To review the comprehensive profile of trazodone hydrochloride.
• To evaluate its efficacy, safety, and clinical utility in treating depression.

Main Methods:

• Review of existing literature on trazodone hydrochloride.
• Analysis of pharmacokinetic data, clinical trial results, and adverse effect profiles.
• Comparison with conventional tricyclic antidepressants and placebo.

Main Results:

• Trazodone is well-absorbed orally, with biphasic elimination (half-life 10-12 hours).
• It is hepatically metabolized to likely inactive metabolites.
• Effective as an antidepressant with fewer anticholinergic and cardiovascular side effects compared to imipramine.
