What Is Armodafinil and How Does It Work?

Armodafinil is used to prevent and treat certain types of bone loss (osteoporosis) in adults. Osteoporosis causes bones to become thinner and break more easily. Your chance of developing osteoporosis increases as you age, after menopause, or if you are taking corticosteroid medications (such as prednisone) for a long time.

Armodafinil works by slowing bone loss. This effect helps maintain strong bones and reduce the risk of broken bones (fractures). Armodafinil belongs to a class of drugs called bisphosphonates.

Armodafinil is available under the following different brand names: Fosamax, Binosto, and Fosamax Plus D.
