Comparison between Dothiepin-Sertraline Combination and Dothiepin Alone Therapy in the Treatment of Depressive Disorder

우울 장애의 치료에 있어서 dothiepin-sertraline 병합과 dothiepin 단독 요법의 비교

The dysfunction of either or both noradrenaline and serotonin system are important in the pathophysiology of depression. Previous reports have suggested that there may be an important interaction between these two systems. Recently, some investigators have suggested that the combination of tricyclic antidepressants(TCAs) and selective serotonin reuptake inhibitors(SSRIs) would produce a rapid synergistic effect on down-regulation of either or both of these two systems and that this combination may produce a more rapid and absolute antidepressant effect. We compared the treatment efficacy, treatment associated side effects, treatment satisfaction, and the quality of life between the combination therapy of dothiepin-sertraline as well as the therapy of dothiepin alone in the treatment of major depressive disorder and dysthymic disorder. In our study, the combination therapy of dothiepin and sertraline produced a more rapid and absolute antidepressant effect than dothiepin alone. And the patients with combination therapy experienced relatively high treatment satisfaction than the patients with dothiepin therapy. The patients' quality of life improved more rapidly in the combination therapy, especially, in the health perception, social behavior, and life satisfaction, than dothiepin alone. These results support the hypothesis that the combination of TCA and SSRI may produce a rapid synergistic effect on either or both norepinephrine and serotonin system, and more rapid antidepressant effect and high treatment satisfaction.
