PY - 2013 T2 - Katzung & Trevor's Pharmacology: Examination & Board Review, 10e AB - Calcium and phosphorus, the 2 major elements of bone, are crucial not only for the mechanical strength of the skeleton but also for the normal function of many other cells in the body. Accordingly, a complex regulatory mechanism has evolved to tightly regulate calcium and phosphate homeostasis. Parathyroid hormone (PTH) and vitamin D are primary regulators (Figure 42–1), whereas calcitonin, glucocorticoids, and estrogens play secondary roles. These hormones or drugs that mimic or suppress their actions are used in the treatment of bone mineral disorders (eg, osteoporosis, rickets, osteomalacia, Paget's disease), as are several nonhormonal agents.
