Treatment Regimens for Peptic Ulcer Disease and H. pylori Infection
For H. pylori-positive peptic ulcer disease, start standard triple therapy after 72-96 hours of intravenous PPI administration and continue for 14 days to prevent recurrent bleeding and achieve eradication. 1
Initial Management: Acute Bleeding Peptic Ulcer
When managing bleeding peptic ulcer, begin with:
- Intravenous PPI for 72-96 hours before starting eradication therapy 1
- Test all patients for H. pylori using urea breath test (88-95% sensitivity) or stool antigen testing (94% sensitivity) 1
H. pylori Eradication Regimens
First-Line Therapy (14 days total duration)
Standard Triple Therapy - Use when clarithromycin resistance is low 1:
- PPI (standard dose): Twice daily, 30 minutes before meals
- Esomeprazole 20-40 mg OR Rabeprazole 20-40 mg (preferred) 2
- Omeprazole 40 mg, Lansoprazole 45 mg, or equivalent
- Clarithromycin 500 mg: Twice daily
- Amoxicillin 1000 mg: Twice daily
- Alternative: Metronidazole 500 mg twice daily (if penicillin allergy)
Bismuth Quadruple Therapy - Preferred when clarithromycin resistance is high 3:
- PPI (standard dose): Twice daily, 30 minutes before morning and evening meals
- Bismuth subsalicylate: 2 tablets or capsules four times daily, 30 minutes before meals and bedtime
- Tetracycline HCl 500 mg: Four times daily, 30 minutes after meals
- Metronidazole 500 mg: Four times daily, 30 minutes after meals
Sequential Therapy (10 days total) 1
Use when clarithromycin high resistance is detected and patient compliance can be maintained:
Days 1-5:
- PPI (standard dose): Twice daily
- Amoxicillin 1000 mg: Twice daily
Days 6-10:
- PPI (standard dose): Twice daily
- Clarithromycin 500 mg: Twice daily
- Metronidazole 500 mg: Twice daily
Second-Line Therapy (10-14 days)
If first-line therapy fails 1:
Levofloxacin Triple Therapy:
- PPI (standard dose): Twice daily
- Levofloxacin 500 mg: Once daily in morning (or 250 mg twice daily)
- Amoxicillin 1000 mg: Twice daily
Alternative - Rifabutin Triple Therapy (14 days) 2, 3:
- Rifabutin 150 mg: Twice daily
- Amoxicillin 1 g: Three times daily
- Esomeprazole or Rabeprazole 40 mg: Twice daily, 30 minutes before meals
Non-H. pylori Peptic Ulcer Treatment
Uncomplicated Peptic Ulcers 4
Duration based on ulcer size:
- Duodenal ulcers and gastric ulcers <2 cm: 4 weeks of PPI therapy
- Gastric ulcers ≥2 cm: 8 weeks of PPI therapy
PPI dosing:
- Omeprazole 20-40 mg daily OR
- Lansoprazole 30 mg daily OR
- Esomeprazole 20-40 mg daily OR
- Rabeprazole 20 mg daily
NSAID-Induced Ulcers 5
Active ulcer treatment:
- Discontinue NSAID if possible
- PPI therapy for 4-8 weeks (healing rate 95% when NSAID stopped) 4
If NSAID cannot be discontinued:
- PPI therapy continues throughout NSAID use
- Consider switching to lower-risk NSAID (e.g., ibuprofen instead of ketorolac)
Prevention in patients requiring continued NSAID use 5:
- With ulcer history: PPI (preferred) or Vonoprazan daily
- With hemorrhagic ulcer history: PPI with or without celecoxib
Low-Dose Aspirin (LDA) Ulcers 5
Prevention in patients with ulcer history:
- PPI (recommended) OR
- Vonoprazan (recommended) OR
- H2-receptor antagonist (suggested alternative)
Erosive Esophagitis
Mild erosive esophagitis (LA Grade A/B) 6:
- Start with standard PPI therapy
- Reserve P-CABs (vonoprazan) for patients who fail twice-daily PPI therapy
Severe erosive esophagitis:
- May consider P-CAB therapy, though insufficient evidence for first-line use 6
Critical Timing Considerations
- Bleeding peptic ulcer: IV PPI for 72-96 hours, then start eradication therapy 1
- All eradication regimens: 14 days is superior to shorter durations 1, 2
- PPI administration: 30-60 minutes before meals for optimal acid suppression 2
- Test-of-cure: Perform 4-6 weeks after completing eradication therapy using urea breath test or stool antigen test 1
Common Pitfalls to Avoid
- Do not use clarithromycin-based therapy empirically in areas with >15% clarithromycin resistance 1, 3
- Avoid pantoprazole in amoxicillin-containing regimens due to lower potency 2
- Do not use 7-day regimens - 14 days is the recommended duration 1, 2
- Do not rely on serology for test-of-cure - use urea breath test or stool antigen 1
- Confirm H. pylori status before starting empirical therapy to avoid unnecessary antibiotic exposure 1
