Summary

Proton pump inhibitors (PPIs) show greater efficacy than H2-receptor antagonists for healing ulcers and reflux esophagitis, with similar relapse rates. PPIs offer convenience but are less effective for H. pylori eradication compared to triple therapy.

Area of Science:

  • Gastroenterology
  • Pharmacology

Background:

  • Proton pump inhibitors (PPIs) and H2-receptor antagonists (H2-blockers) are key treatments for acid peptic disorders.
  • Efficacy and safety profiles determine the future therapeutic role of PPIs.

Purpose of the Study:

  • To compare the efficacy and safety of PPIs versus H2-blockers for acid peptic disorders.
  • To evaluate PPIs in healing ulcers, managing reflux esophagitis, and eradicating Helicobacter pylori.

Main Methods:

  • Comparative controlled trials were analyzed.
  • Efficacy in healing duodenal/gastric ulcers and reflux esophagitis was assessed.
  • Symptom relief, relapse rates, and H. pylori eradication were compared.

Main Results:

  • PPIs demonstrated slightly higher efficacy than H2-blockers in healing ulcers and providing faster symptom relief.
  • PPIs were substantially more effective for reflux esophagitis, especially in H2-blocker resistant cases.
  • Prolonged PPI treatment significantly reduced esophagitis relapse rates compared to H2-blockers.
  • PPIs with amoxicillin were convenient for H. pylori eradication but less effective than triple therapy.

Conclusions:

  • PPIs offer superior efficacy for ulcer healing and reflux esophagitis management compared to H2-blockers.
  • While PPIs have advantages in convenience and safety, their role in H. pylori eradication requires further optimization.
  • Future prospects for PPIs hinge on balancing efficacy, safety, cost-effectiveness, and optimal dosing.
