What is the initial treatment for peptic ulcer disease?

Initial Treatment for Peptic Ulcer Disease

The initial treatment for peptic ulcer disease should include a proton pump inhibitor (PPI) such as omeprazole 20 mg twice daily, along with eradication therapy for H. pylori if present, as this approach addresses both acid suppression and the underlying cause of the disease. 1, 2, 3

Treatment Algorithm

Step 1: Determine Underlying Cause

• Test for H. pylori infection using urea breath test or stool antigen test (preferred non-invasive methods) 4
• Assess for NSAID use history
• Consider endoscopy for patients ≥60 years or those with alarm symptoms (hematemesis, melena, weight loss, persistent vomiting) 4

Step 2: Initiate Treatment Based on Cause

For H. pylori-Associated Peptic Ulcer:

• First-line regimen: PPI + eradication therapy
  • Preferred regimens due to increasing clarithromycin resistance 4:
    • Bismuth quadruple therapy, OR
    • Concomitant therapy (non-bismuth quadruple therapy)
  • Standard triple therapy if low clarithromycin resistance: PPI + clarithromycin 500 mg twice daily + amoxicillin 1 g twice daily for 14 days 1, 2

For NSAID-Associated Peptic Ulcer:

• Discontinue NSAIDs if possible (heals 95% of ulcers and reduces recurrence from 40% to 9%) 3
• If continued NSAID use necessary:
  • Add PPI for gastroprotection
  • Consider switching to selective COX-2 inhibitor 1
  • Eradicate H. pylori if present (reduces ulcer likelihood by 50%) 4

Step 3: PPI Therapy Duration

• Standard duration: 4 weeks for duodenal ulcers, 8 weeks for gastric ulcers >2 cm 1, 3
• PPI dosing: omeprazole 20 mg twice daily 1, 2
• Clinical trials show healing rates of 80-100% within 4 weeks with PPI therapy 3

Efficacy of Treatment

• H. pylori eradication reduces ulcer recurrence from 50-60% to 0-2% 1, 3
• Omeprazole 20 mg daily has demonstrated superior healing rates compared to ranitidine (82% vs. 63% at 8 weeks) 2, 5
• For refractory ulcers (resistant to H2-receptor antagonists), omeprazole 40 mg daily has shown 97% healing rates 6

Follow-up

• Confirm H. pylori eradication 4 weeks after completing therapy 1
• Consider endoscopic follow-up in 8-12 weeks to confirm healing, especially for gastric ulcers to rule out malignancy 1
• Outpatient follow-up within 1-2 weeks 1

Common Pitfalls to Avoid

1. Inadequate treatment duration: Ensure full course of PPI therapy (4 weeks for duodenal ulcers, 8 weeks for larger gastric ulcers) 1, 3

2. Failure to address underlying cause: Simply treating symptoms without addressing H. pylori or NSAID use leads to high recurrence rates 1, 3

3. Overlooking H. pylori testing: The "test and treat" strategy is essential for patients with peptic ulcer disease 1, 4

4. Long-term PPI risks: Extended PPI use may be associated with potential adverse effects including fractures, C. difficile infection, and micronutrient deficiencies 4

5. Inadequate follow-up: Failure to confirm H. pylori eradication can lead to recurrence 1
