Hos raske forsøgspersoner førte peroral administreret prednison (20 mg 3 gange dagligt i 5 dage) ikke til nogen klinisk relevant forandring af alendronats perorale biotilgængelighed (gennemsnitlig stigning fra 20- 44%).
In healthy persons, oral prednisolone (20 mg three times daily for five days) did not result in any clinically meaningful change in the oral bioavailability of alendronate (a mean increase ranging from 20% to 44%).
