A Phase III Clinical Study of Minodronate Tablets in Postmenopausal Women With Osteoporosis

A Randomized, Double-blinded, Active-controlled, Multicentered Phase III Trial to Assess the Efficacy and Safety of Minodronate Tablets in Postmenopausal Women With Osteoporosis

In the randomized, active-controlled, double-blinded, multicenter study, the efficacy and safety of monthly oral minodronate were examined and compared to that of weekly oral alendronate.
