Abstract:
BACKGROUND:Preclinical and clinical evidence indicate that the glutamatergic system might play a role in the pathophysiology of mood disorders. This study was conducted to determine the efficacy and safety of riluzole, a glutamate-modulating agent, in bipolar depression. METHODS:This was an 8-week add-on study of riluzole in combination with lithium in acutely depressed bipolar patients aged 18 years and older. After open treatment with lithium for a minimum period of 4 weeks, subjects who continued to have a Montgomery-Asberg Depression Rating Scale (MADRS) score of >/=20 received riluzole (50-200 mg/day) for 8 weeks. RESULTS:Fourteen bipolar depressed patients entered the study. The linear mixed models for total MADRS score showed a significant treatment effect. No switch into hypomania or mania was observed. Overall, riluzole was well tolerated. CONCLUSIONS:Although preliminary, these results suggest that riluzole might indeed have antidepressant efficacy in subjects with bipolar depression.

临床试验,杂志文章abstract:BACKGROUND:Altered expression of serotonin-1A (5-HT1A) receptors, both presynaptic in the raphe nuclei and post-synaptic in limbic and cortical target areas, has been implicated in mood disorders such as major depression and anxiety. Within the 5-HT1A receptor gene, a powerful dual repressor element (DRE) is regulated ...
