PTH and postmenopausal osteoporosis: Postmenopausal osteoporosis can be treated with bisphosphonates (alendronic acid, risedronate, ibandronate, zoledronic acid), with monoclonal antibodies (denosumab), with calcium and vitamin D, or with parathyroid hormones (teriparatide/abaloparatide), with hormone replacement therapy with progesterone and estrogen, with a selective estrogen receptor modulator (raloxifene), or with tibolone, which has partial agonist activity at estrogen, progesterone, and androgen receptors [4].
