Abstract:
Teriparatide is the recombinant human N-terminal fragment (1-34) of endogenous human parathyroid hormone, and it is the first bone anabolic agent for the treatment of osteoporosis. When given as once-daily subcutaneous injections, teriparatide can reverse the course of osteoporosis by stimulating formation of new bone and restoring lost architecture. Teriparatide (20 microg) treatment of osteoporosis in postmenopausal women rapidly increased markers of bone formation and reduced the incidence of vertebral fractures by 65% and of nonvertebral fragility fractures by 53%. In addition, treatment with this compound increased spine bone mineral density by 10% and hip bone mineral density by 3% at study endpoint. Teriparatide is well tolerated and is not associated with any serious side effects. The compound has been approved in Europe and in the US for the treatment of osteoporosis. Duration of treatment is 18-24 months and the dose does not need to be adjusted for age or gender.

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
