Therapeutic effects of milnacipran, a serotonin and noradrenaline reuptake inhibitor, on post-stroke depression.

Abstract

Depression is common after stroke. While several reports have been published on the use of antidepressants such as selective serotonin reuptake inhibitors and tricyclics for the treatment of post-stroke depression (PSD), no previous study has examined the use of a selective serotonin and noradrenaline reuptake inhibitor (SNRI) for this condition. The present study investigated the efficacy and safety of milnacipran, a SNRI, for the treatment of PSD. A 6-week open study was conducted in 12 patients (two males and 10 females) aged 53-88 years. All patients were diagnosed with major or minor depressive disorder according to DSM-IV, where onset was subsequent to a cerebral infarction or haemorrhage (stroke). Severity of depression was assessed using the 21-item Hamilton rating scale for depression (HAM-D). The maximum total daily dose of milnacipran was in the range of 30-75 mg b.i.d. Three patients experienced side-effects, but none of the side-effects were serious. Two patients dropped out of the study. At the end of the study, 58.3% (7/12) of the total patient population and 70% (7/10) of the patients completing the study were in remission (a final HAM-D score of less than 7 and no longer meeting criteria for major or minor depression). These results suggest that milnacipran may be an effective treatment for PSD.
