Comparison of the effects of a new conjugated oral estrogen, estradiol-3beta-glucoside, with oral micronized 17beta-estradiol in postmenopausal women.

The objective of this article is to evaluate the pharmacokinetics of serum estrone and estradiol levels in women who were taking either 17beta-estradiol-3beta-glucoside (E(2)-3beta-glucoside) or 17beta-estradiol (E(2)) daily and to examine the effects of E(2)-3beta-glucoside and E(2) on postmenopausal symptoms, gonadotropins, hepatic metabolism, and coagulation factors. Healthy postmenopausal women on estrogen who had undergone a hysterectomy were recruited. Subjects were randomly assigned to receive equivalent doses of either E(2)-3beta-glucoside or micronized E(2) for 28 days.
