Abstract:
Remedies for primary osteoporosis are increasing in brands but not always with concomitant improvements in efficacy and safety. Clinical studies suggest that nitrogen-containing bisphosphonates alone display sufficient practical effectiveness to survive as effective therapy. However, their less effectiveness in highly osteopenic patients due to their lack of genuine bone anabolic effect waits improvements. Pinpointing statins as the inducer of BMP-2 provoked a rush of clinical and laboratory studies to identify bone anabolic properties. Clinical studies, even if only through observational, suggest that under conventional dosing conditions for hyperlipemia, the liver-targeted statins now in use display insufficient bone anabolic effect, although laboratory studies seem to be clarifying the mechanisms underlying intrinsic bone anabolic properties. While incomplete, these studies indicate the possibility that, if bioavailability to bone could be improved by simply changing dosing methods and/or deliberate derivatization, the genuine anabolic properties of statins on bone could be extracted and put into therapeutic use.

Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
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...

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...
