Cards

Term
compared to "young, normal" adults of same sex
Definition
T-score
Term
compared to expected normals of patient's age and sex
Definition
Z-score
Term
antacid/calcium supplement; 40% elemental iron
Definition
calcium carbonate
Term
Cholecalciferol
Definition
Vitamin D3
Term
binds to bone hydroxyapatite and inhibits osteoclast-mediated bone resorption
Definition
Alendronate
Term
acts by reducing bone resorption and increasing bone mineral density
Definition
Raloxifene
Term
reduces the number of osteoclast and prevents resorptive activity of the bone resulting in a reduced bone turnover rate. It also temporarily improves bone formation by increasing osteoblastic activity
Definition
Miacalcin
Term
stimulates new bone formation on trabecular and cortical bone surfaces by preferential stimulation of osteoblastic activity over osteoclastic activity
Definition
Teriparatide
Term
receptor activator of nuclear factor kappa-B ligand (RANKL) inhibitor. Binding to the transmembrane or soluble protein RANKL inhibits the formation, function, and survival of osteoclasts resulting in decreased bone resorption and increased bone mass and strength
Definition
Denosumab
Term
calcium absorption
Definition
decreases with age
Term
renal excretion
Definition
increases with age
Term
bone mass
Definition
may be sacrificed to maintain target intra and extracellular concentrations (in elderly)
Term
increased risk of osteoporosis
Definition
on glucocorticoids or have decreased gastric acid production
Term
required to ensure adequate calcium and phosphorus absorption by small bowel
Definition
vitamin D
Term
decreases vitamin D absorption
Definition
anticonvulsants/glucocorticoids
Term
alendronate, ibandronate, risedronate, zoledronic acid
Definition
bisphosphonates
Term
Bisphonate Use
Definition
calcium and vitamin d levels should be corrected; prevents BMD loss/potentially increase BMD, decrease ris kfo vertebral and nonvertebral fractures; can cause GI upset and long-term safety is unknown
Term
monoclonal antibody against RANKL
Definition
Denosumab (Prolia/Xgeva)
Term
denosumab
Definition
diarrhea, N/V; musculoskeletal pain; fatigue; skin infections; hypocalcemia must be corrected prior to starting therapy; ONJ has been reported
Term
Recombinant human PTH
Definition
Teriparatide (Forteo)
Term
Raloxifene Contraindications
Definition
nursing mothers; pregnancy; VTE
Term
inhibits osteoclast activity, stimulates osteoblast activity
Definition
estrogen/HRT
Term
acts on osteoclasts, resulting in decreased resorption and bone turnover
Definition
calcitonin (miacalcin)
