Denosumab Osteoporosis

Denosumab Osteoporosis drug (also sold under the name Prolia) was submitted to the FDA for its approval in February 2009. (The drug is also sold under the name Prolia)

Since that time it has become a popular alternative to daily or weekly tablets for the prevention of fractures in persons with Osteoporosis - especially for those with cancer.

Denosumab inhibits the formation, the activation, and the survival of osteoclasts. (the cells that remove old bone) This decreases bone resorption and it reduces cancer-induced bone destruction.

It is usually prescribed for persons who are at a high risk for fracture,  those who have had a fracture because of  osteoporosis, or those  who have multiple risk factors for fracture. (See: Causes of Osteoporosis)

It is also prescribed for persons who for one reason or another cannot use other osteoporosis medicines or for whom other osteoporosis medicines did not work well
