What is the initial step in managing a patient with a duodenal ulcer, chronic Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) use, and symptoms worsening after meals?

Initial Management of NSAID-Induced Duodenal Ulcer

Start a proton pump inhibitor (PPI) immediately as the initial step in management for this patient with a duodenal ulcer and chronic NSAID use. 1, 2

Immediate Actions

• Initiate PPI therapy immediately (e.g., omeprazole 20 mg once daily or lansoprazole 30 mg once daily) for symptom control and ulcer healing 1, 3
• Discontinue NSAIDs immediately if at all possible, as continuing NSAIDs significantly increases ulcer recurrence and mortality risk even with PPI therapy 1, 2
• If NSAIDs cannot be stopped, maintain PPI co-therapy throughout treatment and consider switching to acetaminophen for pain management 2

Why PPI is the Correct Initial Step

The evidence strongly supports PPI as first-line therapy over the other options:

• PPIs are superior to antacids: Over-the-counter antacids provide only symptomatic relief without addressing ulcer healing, making them inadequate as initial management 1
• PPIs are superior to H2-antagonists: H2-receptor antagonists decrease the risk of NSAID-associated duodenal ulcers but are less effective than PPIs for healing established ulcers 4, 5, 6
• Surgery is not indicated initially: Surgery is reserved for complications such as bleeding refractory to endoscopic treatment, perforation, or gastric outlet obstruction—none of which are present in this case 1

H. pylori Testing and Eradication (Secondary Priority)

• Test for H. pylori infection in all patients with duodenal ulcers, as this should be done but is not the immediate first step 4, 1
• If H. pylori is positive, initiate eradication therapy with triple therapy: PPI + amoxicillin 1000mg twice daily + clarithromycin 500mg twice daily for 14 days 1
• H. pylori eradication prevents recurrent bleeding and ulcer recurrence, but acute ulcer healing with PPI takes priority 4, 1
• Testing during acute bleeding may yield false-negatives, so repeat testing if initially negative 4, 2

Treatment Duration and Follow-Up

• Continue PPI therapy for a full 8 weeks to ensure complete mucosal healing 2, 3
• Omeprazole 20 mg once daily is the optimal dose for NSAID-associated duodenal ulcers, with healing rates of 93% at 8 weeks 7
• After ulcer healing, if NSAIDs must be continued, maintain PPI therapy indefinitely for gastroprotection 1, 2

Critical Pitfalls to Avoid

• Do not delay PPI initiation while waiting for H. pylori test results—start PPI immediately and add eradication therapy if testing is positive 1, 2
• Do not use H2-antagonists alone for NSAID-associated gastric ulcers, as they only protect against duodenal ulcers, not gastric ulcers 1, 5, 6
• Do not continue NSAIDs without gastroprotection, as this dramatically increases recurrence risk even with treatment 2
• Monitor for alarm symptoms (hematemesis, melena, significant weight loss, dysphagia, recurrent vomiting) that would require urgent endoscopy or surgical consultation 1, 2

Alternative Considerations

• Misoprostol (600 mg/day) is effective for preventing and treating NSAID-induced ulcers but causes diarrhea and abdominal pain in approximately 20% of patients, making it less tolerable than PPIs 2, 5, 6
• For high-risk patients requiring continued NSAIDs, the combination of a COX-2 selective inhibitor plus PPI provides the lowest risk for recurrent complications 2
