Bone and Mineral Hemostasis Flashcards
Regulates Parathyroid Hormone
Ionized Calcium
PTH on intestine
Increase Vit D metabolite
PTH on kidney
Decrease calcium excretion
Increase phosphate excretion
High dose PTH on bone
Increase calcium and phospate reabsorption
Low intermittent dose PTH on bone
Bone formation
Vit D metabolite on intestine
Increase calcium absorption
Increase phosphate absorption
Vit D metabolite on kidney
Increase urinary calcium
Direct effect of Vit D metabolite on bone
Increase calcium reabsorption
Increase phosphate reabsorption
Indirect effect of Vit D metabolite on bone
Mineralization
Net serum effect of PTH
Increase Calcium
Decrease Phosphate
Net serum effect of Vit D metabolite

RANK Ligand (RANKL)
Osteoclast and Osteoblast activity
Bone turnover
Inactive Vit D Metabolite
Ergocalciferol, Cholecalciferol
Active form of Vit D

Active Vit D Metabolite
Calcitriol, Doxecalciferol, Paricalcitol, Calcipotriene
Vitamin D Deficiency DOC
Inactive Vit D Metabolite
DOC for Hypoparathyroidism and Hyperparathyroidism in CKD and Liver disease
Active Vit D Metabolite
Released by the Parafollicular C cells in the thyroid gland
Calcitonin
Calcitonin MOA
Inhibit renal reabsorption and bone resorption
Decrease serum phosphate and calcium
Calcitonin SimD
Salcatonin
Tumor marker for Medullary thyroid Ca
Salcatonin
Route of administration of Calcitonin
Nasal spray
Indications for Calcitonin and Bisphosphonate
Paget’s disease of the bone
Hypercalcemia
Osteoporosis
Bisphosphonate
Alendronate (-dronate, -dronic)
Bisphosphonate MOA
Suppress activity of osteoclast inhibit bone resorption
Side effect of Bisphosphonate
Esophagitis (100%)
Jaw osteonecrosis
Renal impairment
Phosphate binding resin
Sevelamer
Sevelamer MOA
binds with dietary phosphate and prevent its absoprtion
reduce uric acid level
