To compare the efficacy and tolerability of oral risedronate and etidronate for treatment of Paget's disease of bone.
Patients from 12 centers in North America received risedronate 30 mg daily for 2 months (62 patients) or etidronate 400 mg daily for 6 months (61 patients) in a prospective, randomized, double-blind study.
Serum alkaline phosphatase (the primary variable), serum bone-specific alkaline phosphatase, and urinary deoxypyridinoline concentrations were monitored for 12 to 18 months.
Serum alkaline phosphatase concentration normalized by month 12 in 73% of risedronate-treated patients, compared with 15% of those receiving etidronate (P<0.001).
Median time to normalization was 91 days for risedronate-treated patients and>360 days for etidronate-treated patients (P<0.001) ; relapse rates were 3% in the risedronate group and 15% in the etidronate group (P<0.05).
At month 18,53% of the risedronate group and 14% of the etidronate group remained in biochemical remission.
Urinary deoxypyridinoline normalized in 87% of patients on risedronate and 57% of patients receiving etidronate (P<0.01) ; serum bone-specific alkaline phosphatase normalized in 73% of patients on risedronate and 18% of patients on etidronate (P<0.001).
Patients who had received etidronate previously had a blunted response to etidronate, but not to risedronate. (...)
