Male & Female Health: Osteoporosis, Menopause & Testosterone Use Flashcards
Cells involved in bone formation
Osteoblasts
Cells involved in bone reabsorption
Osteoclasts
Gold standard to measure BMD and diagnose osteoporosis
Dual energy X-ray absorptiometry (DEXA or DXA scan)
Who should have BMD measured?
women > 65
men > 70
FRAX tool
estimates the risk of osteoporotic fracture in the next 10 years
Interpreting T-score
> -1 = normal
- 1 to -2.4 = Osteopenia (Low bone mass)
< -2.5 = Osteoporosis
Vitamin D daily recommended intake
800-2000 IU, up to 4000 IU safe for adults and adolescence
Calcium Saturability
doses over 500-600 mcg should be dividend
Calcium carbonate vs Calcium citrate
Carbonate = more elemental calcium per unit than citrate, but req acidic environment
Ergocalciferol is
Vitamin D2
Cholecalciferol is
Vitamin D3
Daily calcium recommendation adults
1000-1200mg elemental
How to treat Vit D deficiency?
Vit D2 or D3 for 8-12 wks followed by maintenance dosing
1g Calcium carbonate = how much elemental
400mg
1g Calcium citrate = how much elemental
210mg
Calcium side effects
constipation
Calcium Citrate & carbonate notes
Citrate = take w/ or w/o food
Carbonate = take w/ food, no PPIs
Criteria for initiating treatment Osteoporosis
T-score < -2.5 OR presence of fragility fracture
Criteria for initiating treatment Osteopenia if high risk
T score = -1 to -2.4
and FRAX > 20% major related fracture or >3% hip fracture
First line osteoporosis txm for most patients?
Bisphosphonates
How do bisphosphonates work
inc bone density by inhibiting osteoclast activity and bone reabsorption
When and who should get drug holiday from bisphophonates
3-5 yrs of treatment
low-risk patients

usually weekly, can be daily
Risedronate (Atelvia) dosing
can be daily, weekly and monthly
