Clarithromycin-based triple therapy for H. pylori includes which three components?

• A. Clarithromycin, amoxicillin, and metronidazole.
• B. Clarithromycin, amoxicillin, and a proton pump inhibitor.
• C. Clarithromycin, amoxicillin, and bismuth subsalicylate.
• D. Clarithromycin, metronidazole, and a proton pump inhibitor.

Answer: (B)

In treating H. pylori, the clarithromycin-based triple therapy combines two antibiotics with an acid-suppressing agent to boost eradication rates. The proton pump inhibitor lowers stomach acid, raising the gastric pH so the antibiotics work more effectively and healing is promoted. Amoxicillin attacks the bacterial cell wall, offering reliable activity with typically low resistance. Clarithromycin provides a separate mechanism by inhibiting bacterial protein synthesis through the 50S ribosomal subunit, giving a second line of attack and helping prevent resistance from emerging quickly. Put together, clarithromycin, amoxicillin, and a proton pump inhibitor form the standard clarithromycin-based triple therapy. Other regimens use different drugs (like metronidazole or bismuth) but aren’t part of this specific trio.
