BACKGROUND Up to date, no studies in literature assessed the efficacy of a treatment schedule including i.v. trazodone followed by its oral administration. In light of this lack of evidence, the aim of the present study was to evaluate the efficacy and tolerability of trazodone, administered first i.v. and then orally in a sample of Major Depressive Disorder (MDD) patients. METHODS Thirty four patients underwent i.v. administration of trazodone (75-100 mg in 250 mL of saline) for 1 week. During the second week, oral extended-release formulation (150-300 mg per day) was added to the i.v. administration. Finally, extended-release trazodone was orally administration at doses of 150-300 mg per day. Psychometric scales were performed at baseline (T0), after 2 weeks (T1), 6 weeks (T2), after 3 months (T3), and 6 months (T4). RESULTS The total sample included 34 subjects (14 males and 20 females). There was a statistically significant decrease in Hamilton Depression Rating Scale total scores from T0 to T1 (t=9.06; df=33), from T1 to T2 (t=4.96; df=29), from T2 to T3 (t=4.08; df=19), and from T3 to T4 (t=2.25; df=19); in Hamilton Anxiety Rating Scale total scores from T0 to T1 (t=8.79; df=33) and from T1 to T2 (t=5.61; df=29); in Montgomery-Asberg Depression Rating Scale total scores from T0 to T1 (t=9.30; df=33), from T1 to T2 (t=5.69; df=29), and from T2 to T3 (t=3.16; df=19). CONCLUSIONS This finding confirms previous results on depression with concomitant anxiety symptoms: focusing on trazodone prolonged-release formulation, available data documented its efficacy in MDD.

D014196 Trazodone A serotonin uptake inhibitor that is used as an antidepressive agent. It has been shown to be effective in patients with major depressive disorders and other subsets of depressive disorders. It is generally more useful in depressive disorders associated with insomnia and anxiety. This drug does not aggravate psychotic symptoms in patients with schizophrenia or schizoaffective disorders.
