What are the standing orders for treating gastroesophageal reflux disease (GERD)?

Standing Orders for Gastroesophageal Reflux Disease (GERD)

For patients with GERD, proton pump inhibitors (PPIs) are the most effective first-line pharmacological treatment, superior to histamine-2 receptor antagonists (H2RAs), which are in turn more effective than placebo. 1

Initial Assessment and Treatment Algorithm

First-Line Treatment

• Start with a PPI (e.g., omeprazole, lansoprazole) once daily before the first meal of the day 1, 2, 3
• For patients with typical GERD symptoms (heartburn, regurgitation), empiric PPI therapy is appropriate initial management without the need for endoscopy 1
• If symptoms persist with once-daily dosing, increase to twice-daily PPI dosing 1
• Consider PPI therapy for 4-8 weeks for symptomatic relief in adults 3, 2

Lifestyle Modifications

• Weight loss should be recommended for all overweight or obese patients with GERD 1, 4
• Elevation of the head of the bed for patients with nighttime symptoms or regurgitation when recumbent 1, 4
• Avoid lying down for 2-3 hours after meals to reduce esophageal acid exposure 1
• Other lifestyle modifications should be tailored to individual patient triggers rather than broadly applied to all patients 1

Individualized Lifestyle Recommendations Based on Symptom Triggers

Food-Related Modifications (recommend only if specific triggers identified)

• Avoid foods that consistently trigger symptoms for the individual patient, which may include:
  • High-fat foods, coffee, alcohol, chocolate 1, 5, 6
  • Acidic foods (citrus, carbonated drinks, tomatoes, spicy foods) 1, 5, 6
• Limit meal size and avoid late evening meals 1, 5

Behavioral Modifications

• Smoking cessation if applicable 1, 5
• Avoid vigorous exercise that increases intra-abdominal pressure 1, 5
• Left lateral decubitus position for sleeping may improve pH profiles 4

Treatment Escalation for Inadequate Response

For Persistent Symptoms Despite Standard PPI Therapy

• Increase to twice-daily PPI dosing if once-daily dosing is ineffective 1
• Consider patients with heartburn unresponsive to twice-daily PPI as treatment failures requiring further evaluation 1
• Consider endoscopy after failed empiric therapy to assess for esophagitis or other pathology 1

For Extraesophageal GERD Symptoms (e.g., chronic cough)

• More intensive therapy may be required:
  • PPI twice daily 1
  • Strict antireflux diet (≤45g fat/24h, no coffee, tea, soda, chocolate, mints, citrus, tomatoes, alcohol) 1
  • Consider prokinetic therapy (though metoclopramide is not recommended due to side effects) 1
  • Address comorbid conditions that may worsen GERD (e.g., sleep apnea) 1

Common Pitfalls and Caveats

• Do not use metoclopramide as monotherapy or adjunctive therapy for GERD due to unfavorable risk-benefit profile 1
• There is insufficient evidence supporting the addition of a nocturnal H2RA to twice-daily PPI therapy 1
• Avoid broadly recommending all lifestyle changes to every patient; instead, tailor recommendations based on individual symptom triggers 1
• Persistent symptoms despite maximal medical therapy may warrant consideration of antireflux surgery in appropriate candidates 1, 7
• For short-term or as-needed symptom control in patients without esophagitis, H2RAs may be an alternative to PPIs 1, 8

Maintenance Therapy

• After initial symptom control, titrate to the lowest effective PPI dose 1
• Consider on-demand or intermittent therapy for patients with non-erosive reflux disease 1
• For patients with erosive esophagitis, maintenance therapy is often required to prevent relapse 3, 2
• Periodically reassess the need for continued PPI therapy to minimize potential long-term risks 1
