3. Seven weeks venlafaxine (maximum dose 375 mg) plus quetiapine (maximum 600 mg/day)

Secondary hypotheses:
1. To compare in patients with psychotic depression the tolerability of venlafaxine, imipramine and venlafaxine plus quetiapine
2. To find factors modifying treatment efficacy, such as response to earlier treatments during current episode
3. To evaluate efficacy and tolerability of continuation treatment during four months in responders to treatment at seven weeks
