    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    Medications Superseded by PPIs

    • Histamine-2 (H2) receptor antagonists have largely been replaced by proton-pump inhibitors for reducing stomach acid production.
