It is estimated that there are more than 12.8 million osteoporosis patients in Japan. The objective of the treatment of osteoporosis is to prevent patients from becoming bedridden caused by fractures, thereby maintaining and improving the patients' quality of life (QOL), and the drugs which increase bone mass and reduce the risk of bone fractures are awaited in the clinical settings.

They are only treatment options for osteoporosis that provide the choice of two administration routes to patients in Japan.
