This study is a randomized, open-label, crossover study to assess the bioequivalence of 1
risedronate 150 mg tablet versus 2 risedronate 75 mg tablets administered as a single oral
dose. Approximately 320 subjects will be enrolled from 4 study centers in the U. S.
Official title: A Randomized, Open-Label, 2-Period, Crossover Study to Assess the Bioequivalence of One 150 mg Risedronate Tablet Versus Two 75 mg Risedronate Tablets Administered as a Single Oral Dose in Healthy Male and Female Subjects
Study design: Other, Randomized, Open Label, Dose Comparison, Crossover Assignment, Pharmacokinetics Study
Primary outcome: The primary objective is to assess the bioequivalence of one risedronate 150 mg tablet versus two risedronate 75 mg tablets administered as a single oral dose.
The data to support the interchangeability of one risedronate 150 mg tablet versus two
risedronate 75 mg tablets as monthly dose forms is primarily based on the similarity of in
vitro dissolution and an in vivo study, which showed risedronate absorption is not
dissolution rate limited. These results suggest that monthly dosing of risedronate may be
accomplished by administration of either one risedronate 150 mg tablet or two risedronate 75
mg tablets. The purpose of this study is to provide additional clinical data to support the
interchangeability of these 2 dose regimens.
