Effects of alendronate on bone density in men with primary and secondary osteoporosis

Abstract

Alendronate has been reported to increase bone mineral density (BMD) and reduce fracture risk in women with osteoporosis. As there are no proven safe and effective treatments available for men with osteoporosis, we compared the effects of alendronate (10 mg/day) on BMD, measured using dual-energy X-ray absorptiometry, in a 12-month prospective, controlled, open label study involving (i) men with primary (n = 23) or secondary osteoporosis (n = 18), (ii) postmenopausal women with primary (n = 18) or secondary (n = 21) osteoporosis, and (iii) 29 male and 14 female untreated controls matched by age, height and weight. The patients had one or more vertebral fractures and ranged in age from 34.6 t..
