Helicobacter pylori (H. pylori) stomach infection in adults
Voquezna Dual Pak (vonoprazan / amoxicillin) is a combination of two medications that treat stomach infections caused by the bacteria Helicobacter pylori (H. pylori):
Vonoprazan is a potassium-competitive acid blocker (PCAB). It blocks a protein to stop stomach acid from being made and released into your stomach. This prevents stomach acid from irritating your stomach.
Amoxicillin is a penicillin antibiotic. It kills bacteria by preventing them from making their own protective covering in your body.
