Bisphosphonate compliance in Japan from the perspective of product, formulation, and patient characteristics: analysis of medical insurance claim data

Journal of Pharmaceutical Health Care and Sciences
Background Bisphosphonates are the mainstay drugs for osteoporosis, but in clinical practice, they are often ineffective due to low compliance. However, there have been few studies examining compliance on a product-by-product basis or in detail in Japan.
