Effects of raloxifene hydrochloride on the endometrium of postmenopausal women.

Objective: We evaluated subtle endometrial morphologic changes in postmenopausal women assigned to placebo, raloxifene hydrochloride 200 or 600 mg/day, or conjugated estrogens (Premarin 0.625 mg/day) according to a new estrogenicity scoring system. Raloxifene, a new selective estrogen receptor modulator, was not expected to stimulate the endometrium.

A controlled trial of raloxifene (LY139481) HCl: impact on bone turnover and serum lipid profile in healthy postmenopausal women.

This randomized, double-blind, placebo-controlled, multicenter, 8-week study evaluated short-term effects of raloxifene on bone turnover, serum lipids, and endometrium in healthy, postmenopausal women. A total of 251 women received either placebo, raloxifene HCl 200 or 600 mg/day, or conjugated estrogens (Premarin, 0.625 mg/day).

Antiestrogenic properties of raloxifene.

This 21-day, open-label study evaluated the effects of raloxifene and tamoxifen on estrogen-induced changes in serum levels of anterior pituitary hormones (prolactin, luteinizing hormone, and follicle-stimulating hormone), sex steroids (testosterone, estradiol), and binding globulins [thyroid binding globulin (T3 resin uptake), transcortin, sex steroid binding globulin]. Seventeen healthy male volunteers completed the study after being randomized to one of three treatments: raloxifene, tamoxifen, or placebo. Six subjects received raloxifene (200 mg daily) for 10 days, 6 subjects received tamoxifen [20 mg twice a day (b.
