Introduction: Agomelatine is an antidepressant with unique pharmacological actions; it is both a melatonin agonist and selective serotonin antagonist. Both actions combined are necessary for antidepressant efficacy. Effects on melatonin receptors enable resynchronisation of disrupted circadian rhythms with beneficial effects on sleep patterns.
Areas covered: The issue of use of an antidepressant for depression co-morbid with somatic disorders is covered by the authors. A review of the literature from 2000 to August 2018 was undertaken using Scopus and Web of Science with the key words: agomelatine, depression, medical illness. Depression in Parkinson’s disease, cardiovascular illness and type II diabetes is reviewed with evidence of efficacy. Bipolar depression and seasonal affective disorder may also react favourably. Agomelatine may have specific efficacy on symptoms of anhedonia.
Expert opinion: Despite approval in some major jurisdictions, the drug has failed to gain registration in the United States. A defining issue may be questions about longer term efficacy: unequivocal effectiveness in placebo-controlled relapse prevention studies has not always been demonstrated. Continuation studies suggest maintenance of clinical responsiveness. A major disadvantage of the drug is its’ potential hepatotoxicity and the need for repeated clinical laboratory tests. 相似文献
AbstractObjectives. The treatment of major affective disorders, commonly associated with high disability and elevated social costs may be still considered unsatisfactory. Among all antidepressant drugs, predominantly acting through monoaminergic mechanisms, agomelatine is of particular interest due to another alternative mechanism of action. Targeting melatonergic receptors, agomelatine play a crucial role in synchronizing circadian rhythms, known to be altered in depressed subjects. Methods. A critical review of the literature focusing on efficacy, safety and tolerability of agomelatine in major affective disorders was performed. Additionally, we focused on the potential of agomelatine in enhancing neuroplasticity mechanisms and promote neurogenesis. A total of 136 articles from peer-reviewed journals were identified, of which 50 were assessed for eligibility and 21 were included. Results. Agomelatine, a melatonergic analogue drug acting as MT1/MT2 agonist and 5-HT2C antagonist, has been reported to be effective as antidepressant drug. Studies confirmed not only clinical efficacy but also safety and tolerability of agomelatine. Also, it enhances neuroplasticity mechanisms and adult neurogenesis in brain areas such as hippocampus and prefrontal cortex. Conclusions. Agomelatine actually represents an intriguing option in the treatment of affective disorders. 相似文献
