From the Guidelines

Proton pump inhibitors (PPIs) are the recommended first-line medication for Gastroesophageal Reflux Disease (GERD). The most recent and highest quality study, 1, published in 2022, supports the use of PPIs as the initial treatment for GERD. Common PPI options include omeprazole (20-40 mg daily), esomeprazole (20-40 mg daily), pantoprazole (40 mg daily), and lansoprazole (15-30 mg daily), typically taken 30 minutes before breakfast for optimal effect.

Key Points to Consider

  • Treatment duration varies based on symptom severity, usually starting with a 4-8 week course, though some patients may require longer therapy.
  • PPIs work by blocking the hydrogen-potassium ATPase enzyme system in gastric parietal cells, significantly reducing stomach acid production.
  • Lifestyle modifications should accompany medication, including weight loss if overweight, avoiding meals within 3 hours of bedtime, elevating the head of the bed, and avoiding trigger foods such as caffeine, chocolate, alcohol, and fatty foods.
  • If symptoms persist despite PPI therapy, dosage adjustments or specialist referral may be necessary, as suggested by 1 and 1.

Additional Considerations

  • The use of upper endoscopy in patients with GERD is generally not recommended unless alarm symptoms are present, such as dysphagia, bleeding, anemia, weight loss, or recurrent vomiting, as noted in 1 and 1.
  • Patients with persistent extra-oesophageal symptoms despite PPI therapy should be investigated for non-GORD aetiologies prior to endoscopy or ambulatory pH testing, as recommended by 1.

From the Research

Recommended First-Line Medication for Gastroesophageal Reflux Disease (GERD)

The recommended first-line medication for GERD is a proton pump inhibitor (PPI) 2. PPIs are the drugs of choice for treating GERD due to their potent and prolonged suppression of gastric acid.

Benefits of Proton Pump Inhibitors

PPIs provide the most rapid relief of GERD symptoms and esophageal healing compared to histamine2 receptor antagonists (H2RAs), cisapride, and sucralfate 2. They are also effective in maintaining esophageal healing and symptom relief.

Types of Proton Pump Inhibitors

There are several types of PPIs available, including:

  • Omeprazole
  • Lansoprazole
  • Rabeprazole
  • Pantoprazole 2, 3, 4

Efficacy of Proton Pump Inhibitors

Studies have shown that PPIs are highly effective in healing erosive esophagitis and preventing relapse 4, 5. They are also superior to H2RAs and placebo in healing erosive esophagitis and decreasing relapse rates 4.

Comparison with H2-Receptor Antagonists

H2-receptor antagonists, such as ranitidine, are less effective than PPIs in treating GERD 6, 4. However, they may be considered as an alternative for patients who cannot tolerate PPIs or have mild GERD symptoms.

Conclusion is not allowed, so the response will continue with more information

On-Demand Treatment

On-demand treatment with PPIs has been shown to be effective in patients with endoscopy-negative GERD 6. However, the success rate is higher with PPIs compared to H2-receptor antagonists.

Maintenance Therapy

Maintenance therapy with PPIs is necessary to prevent relapse of esophagitis in patients with healed erosive or ulcerative esophagitis 5. PPIs are the only class of drugs that can minimize relapse significantly in these patients.
