Section snippets
Subjects
Healthy, premenopausal women between the ages of 18 and 45 years were recruited at 12 health centers to participate in a randomized, double-blind, placebo-controlled study. Six centers were located above 40 degrees in latitude (New York, New York; Lyndhurst, Ohio; New Haven, Connecticut; Levittown, New York; Cleveland, Ohio; Salt Lake City, Utah) and 6 were below (Spartanburg, South Carolina; Mobile, Alabama; New Orleans, Louisiana; Houston, Texas; Altamonte, Florida; Miami Beach, Florida).
Results
Seven hundred twenty women were screened. Four hundred ninety-seven patients were enrolled in the study; 466 met criteria for efficacy analysis (1 screening and 1 treatment cycle). Of the 31 patients not included in the efficacy analysis, 17 had insufficient data to analyze, 13 had 1 or 2 treatment cycles that were nonevaluable, and 1 patient had 2 invalid screening cycles and was incorrectly enrolled in the study. Of the remaining 466 patients, 441 patients (95%) completed the trial with 3 out
Comment
PMS afflicts millions of premenopausal women1 and has been described as one of the most common disorders in women. Despite its overwhelming prevalence, clinical investigations exploring its pathophysiologic features have been disappointing. Multiple investigations of basal levels of gonadal steroid hormones, gonadotropins, thyroid, and other hormones have not detected differences between women who have symptoms and those who do not.16 Few therapeutic modalities have proved consistently
