Overview
Drug-induced duodenal ulcers are peptic ulcers occurring in the duodenum primarily due to the use of nonsteroidal anti-inflammatory drugs (NSAIDs) or other medications that impair mucosal defense or increase acid secretion 1.Diagnosis
Clinical presentation includes epigastric pain, often relieved by food or antacids 1.
Endoscopy confirms ulcer presence with characteristic location and appearance 1.
Laboratory tests may show mild anemia or elevated gastrin levels in some cases 1.
Histology may reveal signs of chronic inflammation but is not routinely required 1.Management
First-line treatment: Discontinue the causative drug if possible 1.
Proton pump inhibitors (PPIs): High-dose PPI therapy (e.g., omeprazole 40 mg daily) for ulcer healing 1.
H2 receptor antagonists: As an alternative or adjunctive therapy, especially if PPIs are contraindicated 1.
Prokinetic agents: Consider in cases with delayed gastric emptying, though evidence is limited 1.Special Populations
Pregnancy: Avoid NSAIDs; use PPIs cautiously, considering potential risks to the fetus 1.
Pediatrics: Limited data; careful drug selection and close monitoring are advised 1.
Elderly: Increased risk of complications; PPI dosing may need adjustment for renal function 1.
Comorbidities: Manage concomitant conditions carefully; adjust NSAID use based on cardiovascular risk 1.Key Recommendations
Discontinue the offending drug if feasible to promote ulcer healing (Evidence: Expert opinion 1).
Initiate high-dose PPI therapy for effective healing of drug-induced duodenal ulcers (Evidence: Expert opinion 1).
Monitor for and manage complications, especially in elderly patients or those with comorbidities (Evidence: Expert opinion 1).References
