    Abstract:
    Drospirenone (DRSP), is a unique progestin with antimineralocorticoid activity that has been combined with 17-beta estradiol (E2) for the treatment of symptoms of the menopause in women with hypertension. We assessed the effects of DRSP/E2, E2 alone, and placebo on early morning systolic blood pressure (BP) as well as the rate of rise in systolic BP in 748 postmenopausal women with stage 1 and 2 hypertension at baseline and after 8 weeks of double-blind therapy. Patient characteristics (mean age, 56.5 years, 73% to 77% Caucasian; 13% to 17% African-American) and the clinic (152/95 mm Hg) and 24-hour BP (139/83 mm Hg) measurements were similar at baseline. The early morning systolic BP was reduced significantly on DRSP at 3 mg, 2 mg, and 1 mg with E2 compared with placebo, while E2 alone was similar to placebo. The reductions in early morning systolic BP were larger with increasing dose. Changes in the rate of rise in systolic BP between the lowest values during sleep and following a plateau period post-awakening was significant for the 3 mg DRSP group. In conclusion, DRSP/E2 induced significant reductions in early morning systolic BP in post-menopausal women. This attribute could play a potential role in reducing some of the untoward cardiac and cerebrovascular events that have been observed in studies of other progestins/estrogens in postmenopausal women.
