Which combination represents the standard triple therapy for Helicobacter pylori infection?

• A. Amoxicillin bid, Metronidazole bid, and Omeprazole daily.
• B. Clarithromycin bid, Amoxicillin bid, and Omeprazole daily.
• C. Tetracycline bid, Metronidazole bid, and Omeprazole daily.
• D. Amoxicillin alone with a PPI.

Answer: (B)

The main idea is that standard therapy to eradicate Helicobacter pylori combines a proton pump inhibitor with two antibiotics to both suppress acid and attack the bacteria from two different angles. The proton pump inhibitor lowers gastric acidity, which helps the antibiotics work better and aids mucosal healing. The two antibiotics—clarithromycin and amoxicillin—have different mechanisms, providing a stronger, synergistic assault on H. pylori and helping to prevent resistance from developing. So this exact combination—clarithromycin plus amoxicillin along with a proton pump inhibitor—follows the classic standard triple therapy pattern. Alternatives exist in practice, such as regimens that swap in metronidazole or use other antibiotics, but those are not the traditional standard triple therapy. Using only one antibiotic with a PPI wouldn’t reliably eradicate the infection.
