[New development in bisphosphonate treatment. Bisphosphonates and gastrointestinal adverse effects].

Endoscopic examination suggested gastric mucosal damage by NSAID is more serious than that of bisphosphonates. In addition, the incidence of GI-adverse effects (AEs) is reported to be insignificant, if the incidence is adjusted by history of peptic ulcer, drugs for comorbidity, sex, age and/or ways of evaluation of the AEs. The anxiety for taking medication under empty stomach may contribute to the increase of GI-AEs. Some consideration must be taken for patients with past history of peptic ulcer, and/or drug user such as NSAIDs.
