  Purpose
The purpose of this trial is to study the efficacy of a 35 mg delayed release weekly dosing regimen as compared to the standard daily dosing regimen of risedronate 5 mg daily.

Condition Intervention Phase
Postmenopausal Osteoporosis Drug: risedronate Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Treatment
Official Title: A Non-inferiority Comparison of 35 mg Delayed-release Risedronate, Given Once-weekly Either Before or After Breakfast, & 5 mg Immediate-release Risedronate, Given Once-daily Before Breakfast, in the Treatment of Postmenopausal Osteoporosis.
