Changes in bone markers after once-weekly low-dose alendronate in postmenopausal women with moderate bone loss.
Maturitas 2008; 60(2):170-6M

Abstract

BACKGROUND

High bone turnover, with bone resorption exceeding bone formation, is a major mechanism of postmenopausal osteoporosis. Therefore, inhibition of bone resorption is a rational approach for the prevention of bone loss. The objective of the current study was to determine the short-term efficacy of once-weekly low-dose alendronate in the prevention of bone loss, via bone turnover markers, in early postmenopausal Korean women with moderate bone loss.

METHODS

This study involved a 12-week, randomized, double-blind clinical trial that compared the effects of placebo with alendronate 20mg once weekly. All subjects received supplemental calcium 600 mg and vitamin D 400IU daily. We recruited 63 postmenopausal women (ranging from 50 to 65 years of age) with the lowest lumbar spine bone mineral density (BMD) at least 2.0 S.D. below the mean value for young healthy adults. BMD was measured at baseline and serum alkaline phosphatase (ALP), osteocalcin, C-terminal telopeptide of type I collagen (CTX), and osteoprotegerin (OPG) were measured at baseline and 12 weeks after treatment.

RESULTS

We randomly assigned 63 women to either placebo or alencronate 20 mg once a week for 3 months. Forty-nine women continued and completed all 3 months. After 3 months, bone resorption markers were significantly decreased in the alendronate group than in the placebo group: CTX -47.2% vs. 15% (p<0.01), ALP 1.6% vs. 25.9% (p=0.01), osteocalcin -29.2% vs. -13.6 (p=0.06). Women who received alendronate showed similar results to those who received placebo with regard to adverse events.

CONCLUSION

Once-weekly low-dose alendronate may be a cost-effective and safe method of suppressing bone turnover in early postmenopausal women with moderate bone loss.
