Sixty-four perimenopausal and postmenopausal women without depression or anxiety but reporting vasomotor symptoms after hormone discontinuation entered a 1-week, single-blind, placebo lead-in phase, followed by a 6-week, flexible-dose, double-blind phase with paroxetine controlled-release (12.5-25 mg/d) or placebo. The primary outcome measure was a change in vasomotor symptoms. Other measures included changes in depressive symptoms and overall functioning.
Fifty subjects (paroxetine controlled-release, n = 27; placebo, n = 23) completed the study. At study entry, subjects had an average of 17 hot flushes per week, had used hormones for more than 5 years (median = 66 months, interquartile range = 18-120 months), and had discontinued treatment for less than 1 year (median = 5 months, interquartile range = 2-10 months) before study enrollment. Paroxetine controlled-release was more efficacious than placebo for the alleviation of vasomotor symptoms (mean reduction of 6.1 vs 2.8 hot flashes per week, respectively; P = .03). Depressive symptoms also improved with paroxetine (mean reduction of 3.6 points vs 0.4 points in Montgomery-Asberg Depression Rating Scale total scores; P = .01).
Treatment with paroxetine controlled-release may constitute an efficacious alternative for symptomatic perimenopausal and postmenopausal women after menopausal hormone discontinuation.
