Osteoporosis, Menopause, and Testosterone Use Flashcards
In what patient population is osteoporosis most common in?
Postmenopausal women
What medications are used as calcium supplements? What % elemental calcium is in each?
Calcium carbonate (Os-Cal, Tums) - 40% Calcium Citrate (Calcitrate, Citracal) - 21%
How much elemental calcium is in each gram of calcium carbonate and calcium citrate?
Calcium carb: 400mg elemental calcium
Calcium citrate: 210 mg elemental calcium
What medications are approved for prevention and treatment of osteoporosis?
Prevention: Bisphosphonates and Raloxifene
Treatment: bisphosphonates, denosumab, PTH analogs, and calcitonin
Criteria for initiating treatment of osteoporosis and osteopenia
Osteoporosis: postmenopausal women or men >50 with BMD T-score -2.5 or less OR presence of fragility fracture
Osteopenia: T-score -1 to -2.5 AND FRAX score indicates a 10-year probability of major osteoporosis-related fracture 20% or more or 10 year hip fracture probability of 3% or more
What medications are bisphosphonates?
Oral : Alendronate (Fosamax), Risedronate, Ibandronate
Injectable: Ibandronate (Boniva), Zoledronic acid (Reclast)
Oral bisphosphonate CI, warnings, and SE
CI: Hypocalcemia, inability to sit or stand upright for at least 30 minutes
Warnings: osteonecrosis of jaw, atypical femur fractures, esophagitis, esophageal ulcers, erosions, hypocalcemia, renal impairment (do not use if CrCl <30 or 35 (alendronate)
SE: dyspepsia, dysphagia, heartburn, N/V, hypocalcemia
Injectable bisphosphonates CI, warnings, notes
CI: hypocalcemia; zolendronic acid <35 mL/min
Warnings: renal impairment
Notes: preferred if esophagitis is present
Ibandronate q3m
Zoledronic acid q1-2years
What medications are estrogen agonist/antagonist-containing products?
Raloxifene
Conjugated estrogens/bazedoxifene (Duavee)
Raloxifene MOA
decreases bone resorption
Raloxifene and conjugated estrogens/bazedoxifene (Duavee) indication
Raloxifene: prevention and treatment
Duavee: prevention (postmenopausal women with a uterus)
Raloxifene BBW, CI, SE
BBW: increased risk of FTE and risk of death due to stroke
CI: VTE, pregnancy
SE: hot flashes, peripheral edema, arthralgia, leg cramps
Conjugated estrogens/azedoxifene (Duavee) BBW, CI, warnings
BBW: endometrial cancer, increased risk of DVT and stroke
CI: breast cancer, pregnancy, undiagnosed uterine bleeding, hx or active VTE
Warnings: increased risk of breast cancer and ovarian cancer
Calcitonin MOA
inhibits bone resorption by osteoclasts
Calcitonin warnings and notes
Warnings: hypocalcemia, increased risk of malignancy, hypersensitivity reactions to salmon-derived products
Notes: rarely used for osteoporosis treatment
