title: Comparative effects of conventional vs. novel hormone replacement therapy on blood pressure in postmenopausal women.
abstract: Menopause is commonly characterized by an increase in blood pressure. Higher blood pressure may partially explain the elevated risk for cardiovascular events observed in postmenopausal women. There is a graded relationship between blood pressure and cardiovascular risk which extends to levels of blood pressure well below 140/90 mmHg, the classical established blood pressure limit for the diagnosis of hypertension. Despite this knowledge and the wide availability of consensus treatment guidelines for hypertension, high blood pressure remains untreated or poorly treated in many postmenopausal patients. It is clear that novel and innovative population strategies for lowering blood pressure in postmenopausal women are warranted. Clinical trials suggest that oral estrogen administration may produce either a neutral effect or a small increase in blood pressure in postmenopausal women. Transdermal estrogen administration has not been studied as extensively but may produce a decrease in blood pressure. The mechanisms for the differences observed between oral and transdermal estrogen have not been completely elucidated. Drospirenone (DRSP) is a novel progestin with aldosterone receptor antagonist activity that has been developed for hormone therapy as DRSP/17beta-estradiol (DRSP/E2). In several clinical trials, DRSP/E2 has demonstrated a significant antihypertensive effect as well an additive effect when combined with existing antihypertensive therapy. Despite the wide availability of treatment guidelines, a wide array of antihypertensive agents, and the introduction of hormone replacement therapy that can lower blood pressure, optimizing blood pressure control remains a serious issue confronting the physician who cares for the postmenopausal woman.
