Brand Name Prescription Medications for H. pylori Infection
The most effective brand name prescription medications for H. pylori infection include Talicia® (rifabutin-based triple therapy), Pylera® (bismuth quadruple therapy), and PPI-based combination regimens such as Prevpac® (lansoprazole, amoxicillin, and clarithromycin). 1, 2
First-Line Treatment Options
Bismuth Quadruple Therapy
- Pylera® - Contains bismuth subcitrate potassium, metronidazole, and tetracycline combined with a PPI
- Prevpac® - Contains lansoprazole, amoxicillin, and clarithromycin in a convenient package
- Omeclamox-Pak® - Contains omeprazole, clarithromycin, and amoxicillin
PPI Components (Brand Names)
- Nexium® (esomeprazole)
- Protonix® (pantoprazole)
- Prevacid® (lansoprazole)
- Prilosec® (omeprazole)
- Aciphex® (rabeprazole)
Treatment Selection Based on Antibiotic Resistance
Areas with Low Clarithromycin Resistance (<15%)
- Standard Triple Therapy (14 days): PPI (Nexium® or Aciphex®) + clarithromycin + amoxicillin 2
- PPI (standard dose) twice daily
- Clarithromycin 500mg twice daily
- Amoxicillin 1000mg twice daily
Areas with High Clarithromycin Resistance (≥15%)
- Bismuth Quadruple Therapy (14 days): PPI + Pylera® 2
- Talicia® - FDA-approved rifabutin-based triple therapy containing rifabutin, amoxicillin, and omeprazole 1
Second-Line Treatment Options
If first-line treatment fails, options include:
Levofloxacin-based triple therapy (in areas with low fluoroquinolone resistance) 2, 3
- PPI (standard dose) twice daily
- Levofloxacin 500mg once daily or 250mg twice daily
- Amoxicillin 1000mg twice daily
Rifabutin triple therapy (14 days) 1, 2
- Rifabutin 150mg twice daily
- Amoxicillin 1g three times daily
- PPI (preferably esomeprazole or rabeprazole) 40mg twice daily
Important Considerations
PPI Selection: Higher-potency PPIs like Nexium® (esomeprazole) or Aciphex® (rabeprazole) at 40mg twice daily are more effective than lower-potency options 1
Treatment Duration: All regimens should be administered for 14 days to increase eradication rates by approximately 5% 2
Medication Timing: PPIs should be taken 30 minutes before meals on an empty stomach to maximize effectiveness 2
Confirmation of Eradication: Urea breath test or monoclonal stool antigen test should be performed at least 4 weeks after completing treatment, with PPIs discontinued at least 2 weeks before testing 2
Antibiotic Resistance: After two treatment failures, antimicrobial susceptibility testing should guide further treatment whenever possible 2, 4
Common Pitfalls to Avoid
Inadequate PPI Dosing: Using once-daily PPI instead of twice-daily reduces efficacy 2
Insufficient Treatment Duration: Less than 14 days results in lower eradication rates 2
Reusing Failed Antibiotics: Avoid using the same antibiotic after therapeutic failure, particularly clarithromycin 2
Ignoring Penicillin Allergy: For patients with penicillin allergy, bismuth-containing quadruple therapy is recommended as first-line treatment 2
Overlooking Drug Interactions: Be aware of potential interactions between PPIs and other medications 5
By following these evidence-based recommendations and selecting appropriate brand name medications, H. pylori eradication rates of over 80% can be achieved, reducing the risk of peptic ulcer disease recurrence and potential complications like gastric cancer.
