20% øgning i biotilgængeligheden af ibandronsyre (som ligger inden for den normale variabilitet for biotilgængeligheden af ibandronsyre), formentlig som et resultat af den reducerede gastriske surhedsgrad.
In healthy male volunteers and postmenopausal women, intravenous ranitidine caused an increase in ibandronic acid bioavailability of about 20% (which is within the normal variability of the bioavailability of ibandronic acid), probably as a result of reduced gastric acidity.
