Boniva
Func. class.:
Bone-resorption inhibitor, electrolyte modifier
Chem. class.:
Bisphosphonate
Inhibits bone resorption, apparently without inhibiting bone formation and mineralization; absorbs calcium phosphate crystals in bone and may directly block dissolution of hydroxyapatite crystals of bone; more potent than other products
Osteoporosis and prophylaxis
Unlabeled uses:
Hypercalcemia of malignancy, osteolytic metastases, Paget’s disease, osteoporosis (treatment/prevention) in those taking anastrozole
Achalasia, esophageal stricture, hypocalcemia, intraarterial administration, renal failure, hypersensitivity to bisphosphonates
Precautions:
Pregnancy (C), breastfeeding, children, geriatric patients, anemia, chemotherapy, coagulopathy, dental disease, diabetes mellitus, dysphagia, GI/renal disease, GERD, hypertension, infection, multiple myeloma, phosphate hypersensitivity, vit D deficiency
