peptic ulcer disease Flashcards
Prophylaxis vs treatment
prophylaxis: PPIs preferred
treatment: PPIs, histamine blockers, antibiotics
-antacids, H2 blockers, and sucralfate NOT recommended
Dif bt H2 blockers and PPIs
H2 neutralize acid; PPIs inhibit its production
PPI major risk
pneumonia (and other infections)
*also deplete mg + bone minerals
When NOT to use H2
bleeding risk, current GI bleeds, H2 allergies
bacteria a/w Peptic ulcers + how to treat
H pylori
treat with 2-3 antibiotics –> diarrhea is side effect
Why do NSAIDs cause ulcers?
reduces blood flow, bicarb, and mucus in GI
causes of ulcers
H pylori
NSAIDs
alc, stress, smoking
(kinda caffeine, but not really)
Antacid role in ulcers
good for prophylaxis, not treatment
Magnesium hydroxide –> diarrhea
Calcium Carbonate –> constipation
don’t affect systemic pH
Sucralfate
PPI that creates protective barrier for up to 6 hrs
*active only in acidic environments
cimetidine
reacts with CNS meds
H2 blocker
eating pattern to avoid ulcers
5-6 small meals –> avoid pH fluctuations
Misoprostol
good for ulcers caused by NSAIDS
stimulates secretion of mucus and bicarb
TERATOGENIC
Zollinger Ellison syndrome
hypersecretion of acid, causing ulcers
