Novel bone antiresorptive approaches.

Inhibition of bone resorption is a mechanism that has been clinically validated as a means to control bone loss in diseases such as postmenopausal osteoporosis. The development of marketable drugs in this area has resulted in significant clinical benefits; however, improvements can still be made. Several novel antiresorptive mechanisms are currently under consideration in the pharmaceutical industry, which will hopefully result in the development of improved bone antiresorptive therapies.
