Objective To evaluate the effectuate of ramelteon, an MT1/MT2 melatonin receptor agonist used to treat insomnia, on endocrine function in adults with chronic insomnia. Methods This was a double-blind, placebo-controlled, trial of adults (1845 years) with chronic insomnia. Subjects received either ramelteon 16 mg or placebo nightly for 6 months. Hormonal measures of the thyroid, productive, and adrenal axes were analyzed periodic and compared with baseline and placebo values.



Results While isolated changes were detected at whatsoever time points, there were no consistent statistically signi? sky differences surrounded by treatments on measures of thyroid function ( do T4, free T4, TSH, and total T3), adrenal function (AM cortisol, and ACTH), or on most reproductive endocrine measures [LH, FSH, estradiol (women), total, and free testosterone (men)]. Prolactin concentrations were increased boilersuit in women in the ramelteon group compared with placebo ( p ¼ 0.003). No clinical effects of elevated prolactin were reported; average menstrual cycle length, duration of menses, and ovulation probability did non differ between groups. Conclusions Long-term exposure to ramelteon 16 mg, a potent melatonin receptor agonist, resulted in mild, transient increase in prolactin, in women only, that were not associated with measurable reproductive effects. There were no consistent changes in other endocrine measures.
