Mood and performance changes in women with premenstrual dysphoric disorder: Acute effects of alprazolam

This study determined if women with premenstrual dysphoric disorder (PMS) showed impaired mood and performance when they were experiencing their premenstrual symptoms, and if the effects of alprazolam varied as a function of menstrual cycle phase. Under double-blind conditions, the acute effects of placebo and alprazolam (0.25, 0.50, 0.75 mg) were tested during both luteal and follicular phases. Women with confirmed PMS experienced substantial changes in mood as a function of menstrual cycle phase. However, tinder controlled laboratory conditions, acute doses of alprazolam did not improve negative premenstrual mood, bur rather increased negative mood in the follicular phase. Alprazolam impaired task performance, although this impairment was generally similar in both phases when baseline phase differences were taken into consideration. Consistent with the failure of alprazolam to improve mood premenstrually, subjective measures indicative of abuse liability were not increased following alprazolam. Taken together, these data suggest that acute administration of alprazolam doses are not clinically useful for the treatment of PMS. (C) 1998 American College of Neuropsychopharmacology.
