Estrogen Dose Equivalents CEE = conjugated equine estrogen; E2 = estradiol.Graphic courtesy of Kathryn A. Martin, MD.
Low-Dose EstrogenHOPE Trial • Women’s Health, Osteoporosis, Progestin, Estrogen (HOPE) trial • 2600+ postmenopausal women with uterus,treated for 2 years • 8 treatment groups and placebo • CEE 0.625 mg/d ± MPA 2.5 mg/d • CEE 0.45 mg/d ± MPA 2.5 mg/d • CEE 0.45 mg/d + MPA 1.5 mg/d • CEE 0.3 mg/d ± MPA 1.5 mg/d • Placebo • Endpoints: vasomotor symptoms,BMD,endometrial safety CEE = conjugated equine estrogen; MPA = medroxyprogesterone acetate; BMD = bone mineral density.Utian WH, et al.

Ultra–Low-Dose Estrogen and BMDULTRA Trial • BMD increased more in spine (2%)and hip (1.2%) vs placebo1 • Greater bone effect with lowerendogenous E2 1. Ettinger B, et al. Obstet Gynecol. 2004;104:443. 2. Huang AJ, et al. J Bone Miner Res. 2007;22:1791.
Endometrial Effects of Lower Dosesof Estrogens • HOPE trial • Similar endometrial protection with lower doses + MPA compared with commonly prescribed doses1 • Less vaginal bleeding with low dose2 • ULTRA trial • No increased uterine bleeding or hyperplasia compared with placebo3 • Endometrial proliferation 8.5% vs 1.1% with placebo (NS)3 • Ability to use lower-dose progestins, but no consensus on correct progestin dosing4 1.
