title: [Effects of antidepressants on sleep].
abstract: Insomnia and depression are widespread diseases causing deterioration of life's quality and increasing morbidity and mortality of cardiovascular diseases. Both of them and certain antidepressants adversely affect physiological structure of sleep, while others restore it. The latter drugs must be preferred in therapy of depression accompanying insomnia, and some of them may be effective in treatment of insomnias without depression. Most antidepressants cause REM-reduction, generally with increased serotonin-function. Selective H1-antagonists readily induce sleep, and also the inhibition of cholinergic neurons in the general arousal networks promotes sleep. Sleep continuity is improved by the rise of synaptic level of serotonin. Among tricyclic antidepressants trimipramine and amitriptyline are the best to improve sleep. However, the former has low antidepressant effect and the latter has many adverse side effects. Selective serotonin reuptake inhibitors, except paroxetine, improve sleep only at the time and to the extent of restoring depression. Paroxetine has beneficial effect on sleep at the beginning of the treatment. Mirtazapine is the first-line sleep promoter among atypical antidepressants, however, its effect on increasing appetite markedly limits its application. Trazodone causes hangover, and mianserin may induce restless legs. Insomnias without depression demand lower dose of antidepressants than depression.
