A

DRONTES

alendronate

33
Q

moa of dronates

A

bisphosphonates

pyrophosphate analougs that bind hydroxyapatite in bone and inhibit osteoclast activity

34

osteoporposis
hypercalcemia
paget disease of bone

35

treat hypercalcemia

A

dronate/bisphosphonates

36
Q

treat pagets disease

A

dronates

37
Q

what is teriparatide

A

recombinant PTH analog given subcutaneously daily

icnreased osteoblastic activity

38
Q

use of teriparatide

A

osteoproosis - causes increased boen growth vrs antiresorptive threaphy cough cough bisphosphonates

39
Q

toxo of teriparatide

A

transient hypercalcemia

increased risk of osteosarcomas (seen in rodents)

40
Q

drug associated potentially with icnreased risk of osteosarcoma?

A

teriparatide

41
Q

list the drugs used for chronic gout as preventative tx

A

allopurinol
febuxostat
pegloticase
probenecid

42
Q

moa fo allopurinol

A

inhibites xanthine oxisase after being converted to alloxanthing
decrease conversion fo xanthine to uric acid

43
Q

cxl use of allopurinol outside of preventative in chronci gout

A

luekemia and lymphoma to prevent tumor lysis associated urate neprhotpahty

44
Q

what drugs shoudl be of concern when treating simultaenously with allopurinol

A

azothioprine and 6 MP = will be icnreased bc both are normally metabolized by xanthine oxidase

45
Q

what is febuxostat

A

inhibits xanthine oxidase

preventative gout

46
Q

what is pegloticase

A

recombinant uricase that catalyzes metabolism or uric acid to allantoin - more water soluble

47
Q

what is probenecid

A

inhibits reabsorption of uric acid in proximal covoluted tublue - also inhibtis secretino of penicillin

48

a/se of probenecid

A

can ppt uric acid calculi

49

gi side effects

54
Q

use of colchicine

A

acute and prophylactic gout

55
Q

what drugs should be avoided in gout treatmetn?

A
