24
Q

What is the (1) bismuth compound?

A

Bismuth subsalicylate

25
Q

What are the side effects of H2 blockers?

A

(Relatively mild, transient and infrequent)

  • Primarily GI related (Nausea/Diarrhea/Constipation)
  • Headache
26
Q

What was the FIRST H2 blocker to be released?

What was the problem with it?

A

Cimetidine

TONS of drug-drug interactions; CYP450 inhibitor

27
Q

What is a relative contraindication for H2 Blockers?

28
Q

What are the side effects of PPIs?

A

(mostly mild and infrequent)

  • Diarrhea/Dyspepsia/Nausea
  • CDAD (Clostridium Difficile-Associated Diarrhea)
  • Headache
29
Q

What was the first PPI put on the market?

What’s the problem with it?

A

Omeprazole

MANY drug-drug interactions w/ inhibition of CYP450

30
Q

Whta is the best PPI to use in pregnancy?

A

Lansoprazole

“Baby fetus LANce likes lansoprazole during pregnancy”

31
Q

What is the mechanism of action of sucralfate?

A

Cross-linking from interaction with stomach acid

Creates a viscous, sticky polymer which adheres to epithelial cells around ulcer’s crater

(***Acts like internal bandaid)

32
Q

Does sucralfate affect pH?

33
Q

What is the major side effect of Sucralfate?

A

Constipation (Al(OH)3)

34
Q

What are the relative contraindications of Sucralfate?

A

Severe renal failure

Aluminum containing antacids should be avoided

35
Q

What is the mechanism of action of misoprostol?

A

Prostaglandin E1 analog

Provides protective prostaglandin to gastric mucosa and reduces gastric acid release from parietal cell

36
Q

What is important to note about the dual action of misoprostol?

A

EP3 receptors are on both the parietal cell and superficial epithelial cell

37
Q

What is a unique indication of misoprostol?

A

Prevention of NSAID-induced gastric ulceration in patients at high risk of ulcerations and complications

38
Q

What are the side effects of Misoprostol?

A
  • Diarrhea
  • Headache/dizziness
39
Q

42
Q

What are absolute contraindications of Bismuth?

A

GI Bleeding

Salicylate hypersensitivity

43
Q

How do you treat H.pylori?
