Study Notes
Mode of Action of Proton-Pump Inhibitors (PPIs)
- PPIs block the H+/K+ ATPase enzyme system in the gastric parietal cells, reducing acid secretion.
- They inhibit the final step of gastric acid production, providing a potent reduction in stomach acidity.
Example of a Proton-Pump Inhibitor
- Omeprazole is a specific medication classified as a proton-pump inhibitor.
Dosage Recommendations for Long-Term Use
- For long-term treatment of gastroesophageal reflux disease (GERD), the dosage should be tailored to the individual's needs, typically starting at the lowest effective dose.
Medical Uses Excluded from PPIs
- Proton-pump inhibitors are not indicated for the treatment of infections.
Medications Superseded by PPIs
- Histamine-2 (H2) receptor antagonists have largely been replaced by proton-pump inhibitors for reducing stomach acid production.
