Nonhormonal forms of therapy for osteoporosis have been developed with proven efficacy in reducing fracture risk purchase 200 mg quetiapine visa medicine used to stop contractions. Bisphosphonates such as alendronate purchase cheap quetiapine on line medicine 81, risedronate purchase 200mg quetiapine overnight delivery medical treatment, and ibandronate have been conclusively shown to increase bone density and reduce fractures over at least 5 years when used continuously at a dosage of 10 mg/d or 70 mg/wk for alendronate; 5 mg/d or 35 mg/wk for risedronate; 2 order quetiapine in united states online asthma medications 7 letters. Side-by-side trials between alendronate and calcitonin (another approved nonestrogen drug for osteoporosis) indicated a greater efficacy of alendronate. At the higher oral doses used in the treatment of Paget’s disease, alendronate causes gastric irritation, but this is not a significant problem at the doses recommended for osteoporosis when patients are instructed to take the drug with a glass of water and remain upright. Additional promising new treatments undergoing clinical trials include an antibody against sclerostin, that has been shown to stimulate bone formation, and inhibitors of cathepsin K, an enzyme in osteoclasts that facilitates bone resorption. The bisphosphonates exert multiple effects on bone mineral homeostasis, which make them useful for the treatment of hypercalcemia associated with malignancy, for Paget’s disease, and for osteoporosis (see Box: Newer Therapies for Osteoporosis). They owe at least part of their clinical usefulness and toxicity to their ability to retard formation and dissolution of hydroxyapatite crystals within and outside the skeletal system. Some of the newer bisphosphonates appear to increase bone mineral density well beyond the 2-year period predicted for a drug whose effects are limited to slowing bone resorption. Amino bisphosphonates such as alendronate and risedronate inhibit farnesyl pyrophosphate synthase, an enzyme in the mevalonate pathway that appears to be critical for osteoclast survival. The cholesterol-lowering statin drugs (eg, lovastatin), which block mevalonate synthesis (see Chapter 35), stimulate bone formation, at least in animal studies. Thus, the mevalonate pathway appears to be important in bone cell function and provides new targets for drug development. The mevalonate pathway effects vary depending on the bisphosphonate used (only amino bisphosphonates have this property), and may account for some of the clinical differences observed in the effects of the various bisphosphonates on bone mineral homeostasis. With the exception of the induction of a mineralization defect by higher than approved doses of etidronate and gastric and esophageal irritation by the oral bisphosphonates, these drugs have proved to be remarkably free of adverse effects when used at the doses recommended for the treatment of osteoporosis. Esophageal irritation can be minimized by taking the drug with a full glass of water and remaining upright for 30 minutes or by using the intravenous forms of these compounds. Of the other complications, osteonecrosis of the jaw has received considerable attention but is rare in patients receiving usual doses of bisphosphonates (perhaps 1/100,000 patient-years). This complication is more frequent when high intravenous doses of zoledronate are used to control bone metastases and cancer-induced hypercalcemia. This may underlie the occurrence of subtrochanteric femur fractures in patients on long-term bisphosphonate treatment. This complication appears to be rare, comparable to that of osteonecrosis of the jaw, but has led some authorities to recommend a “drug holiday” after 5 years of treatment if the clinical condition warrants it (ie, if the fracture risk of discontinuing the bisphosphonate is not deemed high). It is at least as effective as the potent bisphosphonates in inhibiting bone resorption and has been approved for treatment of postmenopausal osteoporosis and some cancers (prostate and breast). The latter application is to limit the development of bone metastases or bone loss resulting from the use of drugs that suppress gonadal function. Third, denosumab can lead to transient hypocalcemia, especially in patients with marked bone loss (and bone hunger) or compromised calcium regulatory mechanisms, including chronic kidney disease and vitamin D deficiency. Cinacalcet is approved for the treatment of secondary hyperparathyroidism in chronic kidney disease and for the treatment of parathyroid carcinoma. The reasons for its usefulness in the treatment of Paget’s disease and hypercalcemia are unclear but may relate to the need for protein synthesis to sustain bone resorption. The doses required to treat Paget’s disease and hypercalcemia are about one tenth the amount required to achieve cytotoxic effects. With the development of other less toxic drugs for these purposes, the clinical use of plicamycin is seldom indicated.
