Quetiapine XR Versus Sertraline in Acute Bipolar Depression as add-on Therapy

AstraZeneca27 enrolled

Overview

Prospective, open-label, controlled (active comparator), randomized study of 8 weeks follow-up for the evaluation of the efficacy of extended release quetiapine (quetiapine XR) versus Sertraline in addition to previous mood stabilizer treatment (lithium or valproate at stable and clinically therapeutic blood levels) in the treatment of the adult bipolar depression. This multicentric study will be featured in two sites in Spain.

Extended release quetiapine (quetiapine XR)DRUG

Flexible dose from 300 to 600 mg/d (combination of tablets of 50mg, 200mg and 300mg) oral, daily, 8 weeks length. Quetiapine XR was initiated at 50 mg/day and titrated to 100 mg on day 2, 200 mg on day 3, 300 mg on day 4, and flexible doses of 300 to 600 mg/d from day 5 to the end of the study.

SertralineDRUG

Flexible dose from 50 to 200 mg/d (combination of tablets of 50mg and 100mg) oral, daily, 8 weeks length. Sertraline titration: 50 mg on day 1-3, 100 mg on day 4, and flexible doses of 50 to 200 mg/d from day 5 to the end of the study.

adequate mood stabilizerDRUG

An adequate mood stabilizer treatment with lithium or valproate(defined as a serum concentration of 0.5-1.2 mEq/L or 50-100 microg/ml, respectively).
