What are the defense factors for PUD?
Mucus
- Forms a barrier to protect underlying cells from acid and pepsin.
Bicarbonate
- Neutralize hydrogen ions that penetrate the mucus.
Blood Flow
- Poor blood flow can lead to ischemia, cell injury, and vulnerability to attack.
Prostaglandins
- promote vasodilation
- Stimulate the secretion of mucus and bicarbonate
- Suppress the secretion of gastric acid.

2. NSAID-induced ulcers
3. Stress ulcers.
What are the 3 ways antiulcer drugs work?
1. Eradicate h. pylori (antibiotics)
2. Reduce gastric acidity (antisecretory agents, misoprostol)
