Abstract

OBJECTIVE:

The aim of this study was to compare side effects of medroxyprogesterone acetate and norethindrone acetate during postmenopausal hormone replacement therapy in women with and without a history of premenstrual syndrome.

STUDY DESIGN:

Fifty-one postmenopausal women were randomly selected in a double-blind crossover study. The women received 2 mg of estradiol continuously during five 28-day cycles and 10 mg of medroxyprogesterone or 1 mg of norethindrone sequentially for 12 days of each cycle. Daily symptom rating scales were kept.

RESULTS:

The women showed cyclic changes, with negative mood and physical symptoms culminating during the late progestogen phase and positive mood during the estrogen-only phase. Symptoms declined with time but remained after 5 months. Women with a history of premenstrual syndrome responded strongly to both progestogens. Medroxyprogesterone acetate induced less negative and more positive mood symptoms than norethindrone in women with no history of premenstrual syndrome. In both groups medroxyprogesterone caused more physical symptoms than norethindrone.

CONCLUSION:

The addition of medroxyprogesterone to estrogen is preferable to norethindrone with respect to mood symptoms in women without a history of premenstrual syndrome.
