Abstract

OBJECTIVE:

To determine the effect of raloxifene hydrochloride (RLX) on bone mineral density (BMD), biochemical markers of bone metabolism and lipid metabolism in Chinese postmenopausal women.

METHODS:

This was a multicenter, randomized, double blind placebo controlled study in China with a total of 204 postmenopausal women [mean age (60 +/- 5) years (x +/- s) and weight (63 +/- 9) kg (x +/- s)] treated with either RLX 60 mg (n = 102) or placebo (n = 102) daily for 12 months. BMD, serum lipid and bone markers were determined before and after drug administration.

RESULTS:

Compared to placebo, RLX produced a significant increase in both total lumbar spine and total hip BMD. For the lumbar spine, percentage increase in total BMD was 2.30% with RLX compared to a decrease of 0.08% with placebo (P < 0.001). Corresponding values for total hip BMD were 2.46% increase for RLX and 1.07% for placebo (P < 0.05). For biochemical markers of bone metabolism, serum osteocalcin and C-telopeptide, percentage decrease were 27.6% and 24.0% in raloxifene-treated subjects. Corresponding values in placebo were 10.6% decrease and 15.8% increase (RLX compared to placebo, both P < 0.001). For total cholesterol and low-density lipoprotein cholesterol, percentage decrease were 6.4% and 34.6% in the raloxifene-treated group. Corresponding values in placebo were 1.4% increase and 19.1% decrease (RLX compared to placebo, both P < 0.001). No differences were found for high-density lipoprotein cholesterol or triglyceride levels between the two groups. Only 5 subjects discontinued early due to an adverse event (3 in the RLX group and 2 in the placebo group).

CONCLUSIONS:

This study confirms that RLX exerts positive effects on the skeleton, increasing BMD and decreasing biochemical markers of bone metabolism, and decreased total cholesterol and low-density lipoprotein cholesterol in postmenopausal women in China.
