  13. Why should H2 receptor antagonists and proton pump inhibitors be used cautiously in clients who are at high risk for pneumonia (those w/ COPD)?
    They decrease gastric acidity, which promotes bacterial colonization of stomach and respiratory tract

    What are these?
    Proton pump inhibitors used for peptic ulcer disease
  18. What is the expected pharm action for proton pump inhibitors in peptic ulcer disease?
    Reduce gastric acid secretion by irreversibly inhibiting enzyme that produces gastric acid; reduce basal and stimulated acid production
  19. Which antisecretory agent used in peptic ulcer disease has insignificant ADRs short term, but increases risk of gastric cancer and osteoporosis long term??
    Proton pump inhibitors
  20. ___ levels may be increased when used concurrently with omeprazole.
    Digoxin (Lanoxin)
  21. Absorption of ketoconazole (Nizoral), itraconazole (Sporanox), and atazanavir (Reyataz) is extremely decreased when taken concurrently with which antisecretory agent (thus concurrent use should be avoided)?
    Proton pump inhibitors
  22. T/F Pts may sprinkle contents of proton pump inhibitor capsules over food to facilitate swallowing.
  23. Pts should take this proton pump inhibitor once a day prior to eating breakfast.
  24. Pts taking this classification of meds should avoid alcohol and irritating meds (NSAIDs).
    Proton pump inhibitors
  25. Active ulcers are generally treated with proton pump inhibitors for how long?
    4-6 wks
  26. Which proton pump inhibitor can be administerd IV and may cause thrombophlebitis?
  27. For what 2 med classifications used in peptic ulcer disease should pts notify the provider of signs of GI bleeding?
    • H2 receptor blockers
    • proton pump inhibitors
  28. *sucralfate (Carafate)
    What is this?
    mucosal protectant used in peptic ulcer disease
  29. What's the expected pharm action of mucosal protectants?
    To be transformed by acid in stomach, duodenum into thick substance that adheres to ulcer, protecting ulcer from further injury by acid, pepsin
  30. Mucosal protectants can stick to ulcers for how long?
    Up to 6 hrs
  31. This med is used for pts with acute duodenal ulcers and those requiring maintenance therapy; it is under investigation for use in gastric ulcers and GERD.
  32. This med has no systemic effects, but pts should be encouraged to increase dietary fiber and drink min. 1,500 mL fluids/day to prevent constipation.
  33. This med may interfere with the absorption of phenytoin, digoxin, warfarin, and ciprofloxacin. Antacids interfere with its absorption.
  34. This med used in peptic ulcer disease should be taken on an empty stomach.
  35. *aluminum hydroxide (Amphojel)
    aluminum carbonate
    magnesium hydroxide (Milk of Magnesia)
    sodium bicarbonate
    What are these?
    Antacid used in peptic ulcer disease
  36. What's the expected pharm action of antacids use in peptic ulcer disease?
    Neutralize gastric acid and inactivate pepsin; protection may occur by stimulation of prostaglandin production
  37. What class of meds is used to treat PUD by promoting healing and relieving pain; provide symptomatic relief for GERD.
  38. With antacids, which compounds cause constipation? Diarrhea?
    • aluminum, calcium
    • magnesium
  39. What is an option for a pt that is having difficulty managing bowel fxn on antacids?
    Combo product with aluminum hydroxide, magnesium hydroxide, simethicone
  40. Why should pts w/ HTN or HR avoid antacids w/ sodium?
    Fluid retention
  41. Which antacid can lead to hypophosphatemia?
    aluminum hydroxide
  42. Pts. w/ renal impairment should avoid antacids that contain ___.
  43. Antacids should not be administered to pts. who have what?
    GI perf or obstruction
  44. This PUD med class should be used cautiously in pts w/ abdominal pain.
  45. Antacids that contain ___ bind to warfarin and tetracycline and interfere w/ absorption.
  46. Pts should take all meds 1 hour before or after taking this PUD med class?
  47. *misoprostol (Cytotec)
    What is this?
    prostaglandin E analog used in PUD
  48. What's the expected pharm action of prostaglandin E analogs in PUD?
    Act as endogenous prostaglandin in GI tract to decrease acid secretion, increase secretion of bicarbonate and protective mucus, and promote vasodilation to maintain submucosal blood flow...prevent gastric ulcers
  49. This PUD med class is used in pts taking long term NSAIDs to prevent gastric ulcers, and to induce labor by causing cervical ripening.
    prostaglandin E analog
  50. What are the side effects of prostaglandin E analogs?
    • diarrhea
    • abdominal pain
    • dysmenorrhea, spotting
