Agomelatine at doses of 25-50 mg/day demonstrated antidepressant properties in placebo-controlled trials, without causing sexual or cardiac adverse effects, weight gain, or daytime sedation.
Does agomelatine improve symptoms in patients with mood and circadian rhythm disorders?
Agomelatine is a novel antidepressant with melatonin agonist and serotonin antagonist properties that appears effective and well-tolerated without common antidepressant side effects.
Agomelatine (beta-methyl-6-chloromelatonin), which is structurally homologous to melatonin, is a potent agonist of melatonin MT1 and MT2 receptors as well as an antagonist of serotonin 5-HT(2C) receptors. Agomelatine appears to improve sleep without causing daytime sedation. It has not been found to be associated with sexual side effects and discontinuation symptoms. Three placebo-controlled trials, one of them a dose finding study and two of them pivotal trials, suggest that agomelatine is an antidepressant at doses of 25 - 50 mg/day. Agomelatine appears to be well tolerated, without sexual or cardiac adverse effects, weight gain or discontinuation syndromes. Animal studies suggest a possible neuroprotective action of agomelatine, although there are more data in favor of an anxiolytic effect. Substantially more research is needed to establish its role in the treatment of mood and circadian rhythm disorders.
Dubovsky et al. (Thu,) conducted a review in Mood and circadian rhythm disorders. Agomelatine vs. Placebo was evaluated. Agomelatine at doses of 25-50 mg/day demonstrated antidepressant properties in placebo-controlled trials, without causing sexual or cardiac adverse effects, weight gain, or daytime sedation.
