    1 mod risk NSAID
    2 HI risk NSAID
    • Low risk NSAID:
    • Ibuprofen
    • Diclofenac
    • Nabumetone

    • Mod risk NSAID:
    • Naproxen (fyi is best for high CV risk d/t low CV events in studies)

  10. What are the doses for the alternative quadruple therapy for H. pylori?
    • PPI BID (ROL)
    • +
    • Bismuth subsalicylate 525mg (=2 chew tabs) QID
    • +

    • +
    • TCN 500mg QID
  11. Per ACG, which pt's are considered as "high CV risk"?

    Which NSAID is preferred in pt with high CV risk?
    High CV risk = pt who require daily low-dose ASA

    Preferred NSAID = Naproxen (doesnt appear to inc risk of CV events)
  12. For healing or tx of ulcers from NSAID use, what is the general preferred tx choices? Which tx is less tolerated? (2)
    • 1. PPI
    • 2. Misoprostol (Cytotec) 200mcg QID WF (last dose HS) - less tolerated d/t diarrhea, abd cramping, and freq dosing
