Abstract:
Calcimimetics suppress parathyroid hormone (PTH) secretion by allosterically acting on parathyroid calcium-sensing receptor. It has been already shown that one of calcimimetics decreases PTH level, calcium-phosphate product and bone-specific alkaline phosphatase (BAP) in patients with secondary hyperparathyroidism (SHPT) caused by end-stage renal disease. It has been also described that this drug ameliorates osteitis fibrosa in uremic rats. However, there has been so far insufficient evidence showing that calcimimetics increase bone mineral density and decrease fractures in human. Effects of calcimimetics on bone metabolism need to be investigated by clinical studies for longer usage of this drug in the future.

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...
