Erosive Esophagitis PPI Dosing
For erosive esophagitis, initiate treatment with standard-dose PPI once daily (omeprazole 20 mg, lansoprazole 30 mg, or pantoprazole 40 mg) taken 30-60 minutes before meals for 4-8 weeks, and patients with severe disease (Los Angeles grade C/D) require continuous daily maintenance therapy at the same dose to prevent relapse. 1, 2
Initial Treatment Phase
Standard once-daily dosing is the FDA-approved and guideline-recommended approach for healing erosive esophagitis:
- Omeprazole 20 mg once daily, lansoprazole 30 mg once daily, or pantoprazole 40 mg once daily taken 30-60 minutes before meals 1, 3, 2
- Treatment duration is 4-8 weeks, with most patients healing within this timeframe 2, 4
- If erosive esophagitis persists after 8 weeks, an additional 4 weeks of treatment may be given 2
- PPIs must be taken before meals (not at bedtime) for optimal acid suppression 1
Twice-daily dosing is NOT FDA-approved for erosive esophagitis and lacks strong evidence support - this dosing regimen is primarily studied in eosinophilic esophagitis, not erosive esophagitis 5, 1. The evidence provided regarding twice-daily dosing (omeprazole 20 mg BID) pertains to eosinophilic esophagitis, which is a distinct condition from erosive esophagitis 5.
Maintenance Therapy
Patients with healed erosive esophagitis have extremely high relapse rates (80% at one year) without maintenance therapy, making continuous PPI treatment essential: 5, 4
- Severe erosive esophagitis (Los Angeles grade C/D): Continuous daily PPI therapy is strongly recommended and should NOT be discontinued 5
- Standard maintenance dosing: omeprazole 20 mg once daily or equivalent PPI 6, 7, 8
- On-demand or intermittent therapy is NOT recommended for patients with documented erosive esophagitis, as it results in high recurrence rates of erosive disease 5
- Maintenance therapy should be titrated to the lowest effective dose based on symptom control, but daily dosing must be maintained 5, 1
Studies demonstrate that esomeprazole 20 mg maintains healing in over 90% of patients at 6 months, with significantly better outcomes than lower doses or placebo 6, 8. When patients discontinue PPI therapy after healing, 87.5% experience symptom recurrence and 100% show histological recurrence 1.
Disease Severity Considerations
The severity of erosive esophagitis determines the approach to long-term management:
- Los Angeles grade C/D (severe): These patients should generally NOT be considered for PPI discontinuation due to high risk of complications including bleeding and stricture formation 5
- Los Angeles grade A/B (mild): Step-down therapy may be considered after initial healing, but most still require continuous therapy 5
- Dysphagia occurs in 43% of patients with severe esophagitis and resolves with PPI therapy in 83% of cases 9
Common Pitfalls and Caveats
Critical errors to avoid in managing erosive esophagitis:
- Do not use on-demand or intermittent therapy for patients with documented erosive esophagitis - this is only appropriate for non-erosive reflux disease 5
- Do not prescribe twice-daily dosing as initial therapy - this is not FDA-approved and increases costs without proven benefit for erosive esophagitis 1
- Do not discontinue PPIs in patients with severe (grade C/D) disease - these patients require lifelong therapy 5
- Do not instruct patients to take PPIs at bedtime - they must be taken 30-60 minutes before meals for optimal efficacy 1
- H2-receptor antagonists are significantly inferior to PPIs for both healing and maintenance of erosive esophagitis and should not be used 5, 4
Long-Term Safety Monitoring
While continuous PPI therapy is necessary for most patients with erosive esophagitis, periodic reassessment is recommended:
- All patients on long-term PPI therapy should have their indication clearly documented 1
- Patients with Barrett's esophagus, severe erosive esophagitis, or esophageal strictures are definitively indicated for long-term use 5, 1
- Controlled studies support safety of maintenance therapy for at least 12 months 2, 6
