Bromocriptine in the treatment of premenstrual tension syndrome.

Twenty-four women with regular cycles who reported moderate to severe premenstrual tension participated in a double-blind study to test the effectiveness of CB154 on the control of their symptoms. Symptoms were scored daily and were further evaluated objectively twice monthly by physical examination. Control cycle follicular/luteal delta weights were not different statistically from a 0 change (P > .10), despite long-standing symptoms of bloating, swelling, and reported weight gain. CB154 treatment resulted in statistically significant improvement in daily ratings of breast tenderness (P < .005), bloating (P < .02), and depression (P < .05). Significant placebo effects observed for several other symptoms emphasize the psychologic component of this condition as well as the need for caution in the interpretation of any uncontrolled trials for therapies thought effective in the treatment of this disorder.
