Treatment of major depressive disorder in adults.

APA states that effectiveness of antidepressants is generally comparable between and within classes of medications, including SSRIs, SNRIs, TCAs, MAO inhibitors, and other antidepressants (e.g., bupropion, mirtazapine, trazodone). Choose antidepressant based mainly on the following factors: patient preference; nature of prior response to medication; safety, tolerability, and anticipated adverse effects; concurrent psychiatric and medical conditions; specific properties of the medication (e.g., half-life, actions on CYP isoenzymes, other drug interactions); and cost. For most patients, an SSRI, SNRI, mirtazapine, or bupropion is considered optimal.
