Treatment preference and tolerability with alendronate once weekly over a 3-month period: an Israeli multi-center study.

Background And Aims: Osteoporosis is a chronic condition requiring long-term treatment, for which compliance is not easy to achieve. 70 mg of alendronate once weekly (alendronate OW) provides equivalent efficacy to treatment with 10 mg of alendronate once a day (alendronate OD); however, there are relatively few data regarding patient and physician preferences for once-weekly vs daily dosing. The aim of this study was to measure compliance, convenience, tolerance and relative preference of alendronate OW treatment among post-menopausal women with osteoporosis and physician satisfaction, compared with previous treatment with alendronate OD.
