title: Atenolol in premenstrual syndrome: a test of the melatonin hypothesis.
abstract: Eleven patients with prospectively documented premenstrual depression were given 100 mg atenolol or placebo daily to suppress melatonin secretion during the symptomatic premenstrual phase of the menstrual cycle. There was no significant improvement in mood following treatment with atenolol vs. placebo. These findings suggest that bright light may exert antidepressant effects in patients with premenstrual syndrome through mechanisms other than melatonin suppression and that atenolol does not appear to be a viable treatment modality for the majority of patients with premenstrual depression.
