Answer: C. Omeprazole, amoxicillin, and clarithromycin.
The recommended triple-treatment regimen for H. pylori infection is a PPI (eg, omeprazole, 20 mg bid), amoxicillin (1 g bid), and clarithromycin (500 mg bid) for 14 days. Quadruple therapy with Pepto Bismol, metronidazole, tetracycline, and a PPI-ranitidine is an alternative option.
