Osteoporosis and Other Metabolic Bone Disease Flashcards
Osteoporosis treatment of choice
Bisphosphonates
Bisphosphonates MOA
Mimics pyrophosphate, an endogenous bone resorption inhibitor
Bisphosphonates indicated for postmenopausal, male, and glucocorticoid-induced osteoporosis
Alendronate
risedronate
intravenous zoledronic acid
Bisphosphonate ONLY indicated for postmenopausal osteoporosis
Intravenous and oral ibandronate
Contraindications for Bisphosphonates
Pts with creatinine clearances less than 30 to 35 mL/min
Pts who have serious GI conditions
Pts who are pregnant
Adverse effect of Bisphosphonates
Osteonecrosis of the jaw- Black Box Warning
What should the pt do when taking Bisposphonates?
The patient should remain upright for at least 30 minutes after alendronate and risedronate and 1 hour after ibandronate administration
Patient’s serum calcium concentrations must be _______ prior to using bisphosphonates
Normal
Administration
Oral dose should be taken with at least 6 ounces of plain tap water (not coffee, juice, mineral water, or milk) at least 30 minutes before consuming any food, supplements (including calcium and vitamin D), or medications
What is a full human monoclonal antibody used for osteoporosis?
Denosumab
Denosumab MOA
Inhibits RANKL from binding RANK receptor on the surface of osteoclast precursor cells and mature osteoclasts
aka It inhibits osteoclastogenesis and increases osteoclast apoptosis
Indication for Denosumab
women and men at high risk for fracture (used to increase bone mass in men receiving androgen deprivation therapy and in women receiving adjuvant aromatase inhibitor therapy)
Adverse Effects of Denosumab
Bone turnover suppression and serious skin infections (Rare)
What is Raloxifene (Mixed Estrogen Agonists/Antagonists) indicated for?
prevention and treatment of postmenopausal osteoporosis
invasive breast cancer risk reduction
Raloxifene MOA
estrogenic agonist actions in bone but antagonist actions in breast and uterine tissue
Does Raloxifene have positive Lipid effects?
Yup.
Does Raloxifene have reduction in cardiovascular effects?
Na.
Raloxifene contraindications
Pts with active or past history of venous thromboembolic event
When should therapy be stopped?
If the pt anticipates extended immobility
Adverse Reaction
Hot flashes
What is Calcitonin
endogenous hormone released from the thyroid gland when serum calcium is elevated
If a pt is allergic to fish (salmon) should Calcitonin be given?
No. It comes from salamon
What line treatment is Calcitonin?
LAST
Name an Anabolic Therapy
Teriparatide
What is Teriparatide?
It is a recombinant product representing the first 34 amino acids in human PTH
Teriparatide is indicated in who?
postmenopausal women, men, and patients on glucocorticoids who are at high risk for fracture
What position should the pt be in when receiving the first dose?
sitting or lying down in case orthostatic hypotension occurs
Teriparatide Adverse Effects
Transient hypercalcemia ( measure serum Ca at 1 month and decr Ca intake if high)
Teriparatide black box warning
Incr risk of osteosarcoma
