BACKGROUND: Approximately 50% of patients with major depressive disorder (MDD) do not respond after adequate first-line treatment with a selective serotonin reuptake inhibitor (SSRI). Special interest is paid to whether specialist level inpatient psychiatric care results differ from community studies. AIM: To compare switching alternatives after treatment failure with an SSRI; switching to venlafaxine (Dexcel Pharma Israel) versus switching to another SSRI in depressed inpatients. METHOD: A retrospective register study of inpatients was undertaken in a psychiatric tertiary care university center serving an urban catchment area in Israel with a population of more than 900,000. RESULTS: A total of 401 MDD inpatients were assigned to antidepressant treatment. Of these, 232 records (47 venlafaxine, 185 SSRI) were included in the analysis. Patients assigned to venlafaxine treatment were older (mean age 64.3 ± 15 years versus 53.6 ± 17; p<0.01) and had more comorbid physical disorders (80% versus 57%; p<0.001). In the primary analysis, there was no statistical difference between groups in reduction in CGI-S total scores. The secondary end point of achieving a CGI-S score of 2 or less (1 = normal, not at all ill or 2 = borderline mentally ill) was statistically significantly better for the venlafaxine treated inpatients (P=0.02). AEs were reported less than 10% of patients in both groups. CONCLUSION: Patients who remain severely depressed following treatment with an SSRI may gain benefit from the dual-action drug venlafaxine, rather than switching to another SSRI. These findings need to be further supported by prospective studies.
