Women 51+: 1200 mg orally daily
Men 71+ 1200 mg orally daily
NOT all at once, multiple doses of 500 or less
NEED Vit d in combo to see decreased fracture risk
Best Calcium Supps
Carbonate and Citrate
Insoluble Calcium Salts
Carbonate Take with meals to enhance absorption Require acidic pH 1 tablet per dose Cheap
Soluble Calcium Salts
Citrate, Lactate, gluconate
Preferred in patients with achlorhydria (low acid)
2 tablets per dose
Expensive but without regard to meals

Test question

RF for Vit D deficiency
Limited sun malabsorption meds darker skinned obese lack in diet kidney disease

Calcium and Vit D Pearls
Higher dose decrease fracture risk
Constipation
Interacts with drugs
Bisphosphonates
FIRST LINE
Decrease vertebral and hip fractures
Zoledronic decreases mortality
Bisphosphonate special properties
Empty stomach for 30 minutes
Upright for 30 minutes
Full class of water
Adequate Ca and Vit D
Bisphosphonate AE
Osteonecrosis of the jaw
Severe musculoskeletal pain
Atypical femur fractors (holiday from drug)
Teriparatide
SQ daily MAX 2 yrs
Used in very high risk who can’t tolerate bisphosphonates
BEFORE bisphosphonates
Denosumab
MEN
SQ q6 months in doctors office
Suppresses bone turnover
ONJ!!
Oral Bisphosphonates that require upright 30 minutes
Alendronate
Risdronate
Estrogen

Calcitonin
SQ and intranasal (alternate nostrils)
NEED adequate Calcium and Vit D
Limited data
OP in Men
Higher mortality
Testosterone plays a role but not good treatment
Monitoring
DXA Q2 yrs
