Flashcards in 5.1 Gout Deck (15):
1

Which drugs are used for acute attacks of gout? (4)

1) Indomethacin
2) NSAIDs
3) Colchicine
4) Glucocorticoids

2

What is the mechanism by which drugs used to treat acute attacks of gout act?

Supress leukocyte recruitment and activation

3

What is the Colchicine act on tubulin?

Binds tubulin, inhibiting it's polymerization and preventing formation of microtubules, which disrupts mobility of granulocytes, decreasing their migration into the affected area.

4

Besides acting on tubulin, how else does Colchicine act? (2)

1) Blocks cell division by disrupting the mitotic spindle
2) Inhibits synthesis and release of leukotrienes

5

What is the DOC for acute gout attacks?

Indomethacin

6

What are the adverse affects of Indomethacin?

1) Bleeding
2) Na and H20 retention
3) Renal insufficiency

7

What drug is contraindicated with Indomethacin?

Aspirin

8

Why is Aspirin contraindicated with Indomethacin?

(low dose) competes with uric acid for secretion at the PT and causes hyperuricemia.

9

What is the most troublesome adverse affect of Colchicine therapy which has caused NSAIDs to replace them?

Diarrhea

10

What are the adverse affects related to chronic administration of Colchicine? (4)

- hepatic
- renal
- CV disease

12

Which drugs are used to treat chronic gout? (4)

1) Allopurinol
2) Probenecid
3) Sulfinpyrazone
4) Rasburicase

13

What is the MOA of Allopurinol?

Purine analog which inhibits xanthine oxidase facilitating dissolution of tophi

14

What is Allopurinol indicated for? (2)

1) Decrease uric acid synthesis
2) Prevent renal damage during cancer chemotherapy

15

What is the adverse affects of Allopurinol?

Hypersensitivity skin rash may progress to Steven-Johnson syndrome (toxic epidermal necrosis)
