The optimal oral dose selection of ibandronate in Japanese patients with osteoporosis based on pharmacokinetic and pharmacodynamic properties.

ABSTRACT: Ibandronate is a drug widely used outside Japan for the treatment of osteoporosis. It is available in formulations for intermittent intravenous (i.v.) administration and for intermittent (once monthly) oral administration. Ibandronate was recently approved in Japan as an i.v. injection with a dosing regimen of 1.0 mg once a month. To establish the optimal dose for oral administration of ibandronate in Japanese osteoporotic patients, we investigated the pharmacokinetics of and pharmacodynamic response to ibandronate following oral and intravenous administrations to Japanese subjects. Ibandronate (20, 50, 100, or 150 mg) was given orally to healthy postmenopausal Japanese women and to Japanese patients with primary osteoporosis. Serial measurements were obtained for the concentrations of ser
