This study aimed at investigating whet-her oral medroxyprogesterone acetate (MPA) or micronized progesterone (P) combined with micronized estradiol (E2) adversely affect endothelial function in postmenopausal women. Materials and Methods: Randomized, double-blind, crossover trial of MPA or micronized P with oral E2 treatment in menopausal women. Result: Flow-mediated, endothelium-dependent vasodilation of the brachial artery was not sig-nificantly affected by short-term administration of E2 alone or E2 combined with cyclic MPA, or E2 combined with cyclic P. Conclusion: Short-term oral E2 treatment of postmenopausal women alone or with cyclic oral MPA or oral P did not affect flow-mediated en-dothelium-dependent vasodilation.

Abstract

This study aimed at investigating whet-her oral medroxyprogesterone acetate (MPA) or micronized progesterone (P) combined with micronized estradiol (E2) adversely affect endothelial function in postmenopausal women. Materials and Methods: Randomized, double-blind, crossover trial of MPA or micronized P with oral E2 treatment in menopausal women. Result: Flow-mediated, endothelium-dependent vasodilation of the brachial artery was not sig-nificantly affected by short-term administration of E2 alone or E2 combined with cyclic MPA, or E2 combined with cyclic P. Conclusion: Short-term oral E2 treatment of postmenopausal women alone or with cyclic oral MPA or oral P did not affect flow-mediated en-dothelium-dependent vasodilation.
