Q

Ca dosing recommendations

A

Women <50yoa and men 50-70yoa à 1000mg calcium daily (food + supplements)

Q

Options for Ca supplementation

A

Ca Carbonate or Calcium citrate

More detail:
Carbonate: 40% elemental calcium, less expensive, taken with meals- needs acid to be absorbed
Citrate: 21% elemental calcium, acid-independent absorption- does not need to be taken with meals

25
Which bisphosphonate has same generic name but different brand names that are different for sexes?
Risedronate Risedronate (Atelvia) --> females only Risedronate (Actonel) --> females and males
26
Which bisphosphonates are IV?
ibandronate and zoledronic acid
27
Bisphosphonates AE
Osteonecrosis of the Jaw** Others: hypoCa, fragility fractures, esophageal cancer, atrial arrythmias
28
What pts can we not give Bisphosphonates
renal insufficiency (primary mode of elimination) Hypocalcemia, oral prep in pts not upright or swallowing disorder
29
Patient Education for Bisphosphonates
Take first thing in the AM with PLAIN water Remain upright for at least 30 min to reduce GI SE and acid reflux
30
what happens if pt stops Bisphosphonates
drug(s) have residual benefits after discontinuation --> will continue to monitor pt bone density
31
RANK ligand inhibitor name
Denosumab (Prolia)
32
Denosumab (Prolia) MOA
Human monoclonal antibody that inhibits osteoclast formation and reduces bone resorption
33
Denosumab (Prolia) Indications
tx of osteoporosis and bone mets in males AND females
34
Denosumab (Prolia) is given how
subQ injection
35
are Denosumab (Prolia) effects reversible?
Yes Bone mineral density declines to pre-tx levels w/in 2 years of discontinuation and increases bone turnover w/in 3 m of discontinuation
36
Denosumab (Prolia) AE
*Rash, dermatitis *Infections *Upper GI symptoms *Hypocalcemia
37
What pts should be not give Prolia to
hypocalcemic
38
when should we give Prolia
Reserved for patients unresponsive to or unable to tolerate bisphosphonates AND *Patients receiving androgen deprivation therapy for prostate cancer *Patients receiving aromatase inhibitor for breast cancer
39
what tx for osteoporosis is no longer 1st line prevention
Estrogen Therapy
40
what does estrogen therapy increase the risk of
*Increased risk of CVA, clots, and breast cancer *Long-term estrogen increases risk of ovarian cancer
41
what kind of formulations does estrogen therapy come in
*Many formulations and dosage forms approved for prevention *Including estrogen + progestin products
42
estrogen therapy stats that is helps w (not sure how in depth we need to know so added it all!)
Treatment in 10k women for 1 year with estrogen + progestin prevents 6 hip and 6 vertebral fractures *8 more cases of breast cancer *9 more strokes *12 more cases of DVT Treatment in 10k women for 1 year with estrogen alone prevents 7 hip and 6 vertebral fractures *11 more strokes *7 more cases of DVT
43
When to avoid estrogen therapy
*History of stroke *History of coronary events *History of thromboembolism *Breast cancer
44
When to consider estrogen therapy
prematurely menopausal women (<50 years old) or if symptomatic
45
Selective Estrogen Receptor Modulator (SERMs): Name
*Raloxifene
46
Raloxifene MOA
acts like estrogen on bone AND estrogen antagonist in uterus and breast
47
Raloxifene is approved tx for what
osteoporosis
48
Raloxifene AE
*Hot flashes *Leg cramps *Peripheral edema *Thromboembolic events
49
When to avoid Raloxifene

50
Raloxifene is contraindicated in what pt population? not indicated?
Contra: pregnancy and hx of or current thromboembolic disorde Not indicated: Not indicated or recommended for for premenopausal women
51
Raloxifene is useful in what pt population besides osteoporosis
women at high risk of breast cancer (but does not eliminate risk)
52
*Extra Flashcard: Parathyroid Hormone Analogs Names
teriparatide (Forteo®) and abaloparatide (Tymlos®) AND are $$$
53

Peptide hormone that binds to osteoclasts and inhibits bone resorption May have analgesic effect
55
Calcitonin is more derived from what source
Salmon; more potent than mammalian
56
Calcitonin routes
IM, SQ, intranasal
57
Calcitonin AE
*Nausea and flushing with injection *Runny nose and epistaxis with nasal spray
58
when to give calcitonin
Reserved for postmenopausal women who are postmenopausal by at least 5 years *Who are unable to tolerate bisphosphonates *AND have bone pain from compression fractures
59
who not to give calcitonin to
High risk of hip fractures
60
what does calcitonin reduce fracture risk of
small increase in vertebral bone mineral density with a slightly reduced risk of vertebral fractures
61
Reminder to look at green table for fracture site prophylaxis (this was more for reference)
Reminder to look at green table for fracture site prophylaxis (this was more for reference)
62
OTC supplements for bone health
*Glucosamine *Chondroitin *MSM (methylsulfonylmethane) *SAMe (S-adenosy-L-methionine) *Natural anti-inflammatory compounds *Turmeric *Ginger *Boswellia
63
how often do you assess BMD for osteoporotic pts
every 2-3 years
64
Drug holiday timeline if not at high risk of fracture
3-5 years (found in notes of her pwpt)
65
Duration of therapy guidelines for Osteoporosis drugs are set by
American Association of Clinical Endocrinologists (AACE)
66
Drug Holiday time lines for bisphosphonates
*Bisphosphonate drug holidays (consider if condition stable) *Moderate risk—5 years; (IV zoledronic acid - 3 annual doses) *High risk— 6-10 years; (IV zoledronic acid - 6 annual doses)
67
What osteoporosis drug should NOT have a drug holiday
Denosumab (Prolia)
68
Reminder to Look at Duration of Therapy Flow Chart (slide 38)
