LET’S GET STARTED…………
Unit 1- Introduction
• See class handout

GI MEDS AND PLAN OF CARE
PLAN FOR THE DAY:
• Quick Notes Review
• Case Study
• NCLEX Questions
GASTRIC ACID
System
• Esophagus
• Stomach
• Liver/gallbladder
• Pancreas
• Small/large intestine
Gastric acid production
• Parietal cells- H+ production
• Receptors- histamine2
Function
• Stomach pH 1-4
• Digestion
• Defense against infection
WHAT DO WE DO WITH THE
OVERPRODUCTION OF THIS ACID????
****Give antacids= to neutralize!
•
Milk of Magnesia (magnesium
hydroxide)
• TUMS (calcium carbonate)
Heartburn, gastritis, peptic ulcer
disease (PUD)
****Suppress gastric acid!
H2 receptor blockers- bind to H2
receptor
• Pepcid (famotidine)
• Decrease HCl acid production
• Decrease heartburn
GERD, erosive esophagitis, PUD,
H. pylori, gastritis, prevent stress
ulcers
WHAT DO WE DO WITH THE OVERPRODUCTION
OF THIS ACID????
****Suppress gastric acid!
Proton pump inhibitors (PPI)blocks proton pump, stops HCl
production
• Prevacid (lansoprazole)
• Prilosec (omeprazole)
• Protonix (pantoprazole)
Decrease HCl production, decrease
heartburn
• Caution with hepatic disease!!!!
Gastric barrier- adheres to
gastric mucosa/ binds to ulcer
• Carafate (sucralfate)
Decrease heartburn
