Teriparatide is a portion of human parathyroid hormone (PTH), amino acid sequence 1 through 34, of the complete molecule (containing 84 amino acids). Endogenous PTH is the primary regulator of calcium and phosphate metabolism in bone and kidney.
Teriparatide (Forteo) is a synthetic version of the human parathyroid hormone, which helps to regulate calciummetabolism. It promotes the growth of new bone, while other osteoporosismedications improve bone density by inhibiting bone resorption, or breakdown. It is the only osteoporosis medicine approved by the FDA that rebuilds bone. Forteo should be used only in men with osteoporosis and postmenopausal women.
