From the Guidelines
Duodenitis treatment should prioritize addressing the underlying cause, such as Helicobacter pylori infection, and managing symptoms with proton pump inhibitors (PPIs) and lifestyle modifications. For mild cases, lifestyle modifications are recommended, including avoiding spicy foods, alcohol, NSAIDs, and smoking. Medication options include PPIs like omeprazole 20-40mg daily or pantoprazole 40mg daily for 4-8 weeks to reduce stomach acid production, as supported by studies such as 1 and 2. H2 blockers such as famotidine 20mg twice daily can also help. If Helicobacter pylori infection is present, triple therapy is necessary, consisting of a PPI plus two antibiotics (typically amoxicillin 1g twice daily and clarithromycin 500mg twice daily) for 10-14 days, as recommended in 2. For NSAID-induced duodenitis, discontinuing the offending medication and using a PPI is recommended. Key considerations include:
- Testing for Helicobacter pylori and receiving eradication therapy if infection is present, as it has been shown to reduce the rate of ulcer recurrence and rebleeding in complicated ulcer disease 2
- Using PPIs to reduce stomach acid production, which can help alleviate symptoms and promote healing
- Implementing lifestyle modifications to manage symptoms and prevent further irritation
- Considering the use of H2 blockers or other medications as needed to manage symptoms and support healing.
From the FDA Drug Label
1.1 Treatment of Active Duodenal Ulcer Omeprazole delayed-release capsules are indicated for short-term treatment of active duodenal ulcer in adults. Most patients heal within four weeks. Some patients may require an additional four weeks of therapy.
1.2 Helicobacter pylori Eradication to Reduce the Risk of Duodenal Ulcer Recurrence Eradication of H. pylori has been shown to reduce the risk of duodenal ulcer recurrence. Triple Therapy Omeprazole delayed-release capsules in combination with clarithromycin and amoxicillin, is indicated for treatment of patients with H pylori infection and duodenal ulcer disease (active or up to 1-year history) to eradicate H. pylori in adults.
Duodenitis Treatment:
- Omeprazole is indicated for the short-term treatment of active duodenal ulcer in adults 3.
- Triple Therapy with omeprazole, clarithromycin, and amoxicillin is indicated for the treatment of patients with H. pylori infection and duodenal ulcer disease to eradicate H. pylori in adults 4.
- Most patients with duodenal ulcers heal within four weeks of treatment with omeprazole, but some may require an additional four weeks of therapy 4.
From the Research
Duodenitis Treatment
- Duodenitis is often associated with Helicobacter pylori infection, and treatment typically involves eradication of the bacteria.
- Studies have shown that proton pump inhibitor-based triple therapies, such as lansoprazole, amoxicillin, and clarithromycin, are effective in eradicating H. pylori and healing duodenal ulcers 5, 6, 7, 8, 9.
- The choice of treatment regimen may depend on factors such as antibiotic resistance and CYP2C19 genotype status 5, 8.
- High-dose proton pump inhibitor triple therapy with amoxicillin and clarithromycin has been shown to be highly effective in eradicating H. pylori, even in patients with clarithromycin-resistant strains 5, 8.
- The importance of clarithromycin dose in the management of H. pylori infection has been highlighted, with 500 mg b.d. being more effective than 250 mg b.d. in proton pump inhibitor-based triple therapies 9.
Treatment Regimens
- A 10-day course of amoxycillin-clarithromycin-based triple therapy without additional acid suppression has been shown to be highly effective in eradicating H. pylori and healing duodenal ulcer 6.
- A 1-week course of famotidine, amoxicillin, and clarithromycin has been found to be highly effective in eradicating H. pylori and healing duodenal and gastric ulcers 7.
- A 14-day regimen using a high-dose proton pump inhibitor triple therapy consisting of lansoprazole, amoxicillin, and long-acting clarithromycin has been shown to provide an excellent cure rate, regardless of CYP2C19 genotype 8.
