Arylia (Denosumab) for Treatment of Osteoporosis and Bone Loss

Arylia contains the active ingredient Denosumab. Denosumab is a human monoclonal antibody that targets and binds with high affinity and specificity to RANKL. RANKL is a protein that is necessary for the function, formation, and survival of osteoclast. Arylia stops RANKL from activating its receptor RANK, present on the surface of osteoclasts. This prevents osteoclast function, formation, and survival, hence decreasing resorption of bone and increasing bone mass and strength.

It is used to treat:

  • Osteoporosis in postmenopausal women and in men at increased risk of fractures.
  • Bone loss associated with hormone ablation in men with prostate cancer at increased risk of fractures and bone loss in females receiving aromatase inhibitor therapy for breast cancer.
  • Bone loss associated with long-term systemic glucocorticoid therapy in adult patients at increased risk of fracture.
