Randomized Controlled Trial Clinical TrialRisedronate increases bone density and reduces vertebral fracture risk within one year in men on corticosteroid therapy.
Limited information is available on the effect of bisphosphonates in men receiving corticosteroid therapy. We studied 184 men among the patients enrolled in two, double-blind, placebo-controlled, 1-year studies with similar protocols. The studies evaluated the effects of risedronate in patients beginning corticosteroid treatment at a dose of at least 7.5 mg per day of prednisone or equivalent (prevention study) or continuing long-term treatment of corticosteroid at that dose (treatment study). ⋯ When the data from the two studies were combined, the incidence of vertebral fractures decreased 82.4% (95% confidence interval, 36.6%-95.1%) in the pooled risedronate groups compared with placebo (P = 0.008). Risedronate was well tolerated in men, with a similar incidence of upper gastrointestinal adverse events in the placebo and treatment groups. Daily treatment with risedronate increases bone density and decreases vertebral fracture risk within 1 year in men receiving corticosteroid therapy.
