Daily subcutaneous self-injection and weekly subcutaneous injection formulas of teriparatide are available as anabolic agents in Japan. These injection formulas are expected to serve as a new treatment choice for high fracture-risk patients with osteoporosis. In addition, studies using new anabolic agents such as PTHrP, calcilytics, and Wnt inhibitor antagonists/antibodies are under way to develop new anabolic agents. These agents may become new treatment drugs for osteoporotic patients especially with low bone turnover.
