Vonoprazan/amoxicillin, sold under the brand name Voquezna Dual Pak among others, is a co-packaged medication used for the treatment of Helicobacter pylori (H. pylori) infection. [1] It contains vonoprazan (as the fumarate), a potassium-competitive acid blocker and amoxicillin, a beta-lactam antibiotic. [1] It is taken by mouth. [1]
The co-packaged medication was approved for medical use in the United States in May 2022. [1] [2] [3] [4]
Vonoprazan/amoxicillin is indicated for the treatment of H. pylori infection in adults. [1] [5]
The dual therapy of using vonoprazan with amoxicillin has been investigated for the treatment of H. pylori infection [6] and also compared with the triple therapy of using vonoprazan, amoxicillin, and clarithromycin for the eradication of H. pylori infection. [7] Both treatments have been found to be effective. [6] [7] As of 2024, [update] evidence indicates that vonoprazan/amoxicillin therapy has similar efficacy to bismuth-containing quadruple therapies in eliminating H. pylori. [8]
Amoxicillin is an antibiotic medication belonging to the aminopenicillin class of the penicillin family. The drug is used to treat bacterial infections such as middle ear infection, strep throat, pneumonia, skin infections, odontogenic infections, and urinary tract infections. It is taken by mouth, or less commonly by injection.
The urea breath test is a rapid diagnostic procedure used to identify infections by Helicobacter pylori, a spiral bacterium implicated in gastritis, gastric ulcer, and peptic ulcer disease. It is based upon the ability of H. pylori to convert urea to ammonia and carbon dioxide. Urea breath tests are recommended in leading society guidelines as a preferred non-invasive choice for detecting H. pylori before and after treatment.
Peptic ulcer disease is a break in the inner lining of the stomach, the first part of the small intestine, or sometimes the lower esophagus. An ulcer in the stomach is called a gastric ulcer, while one in the first part of the intestines is a duodenal ulcer. The most common symptoms of a duodenal ulcer are waking at night with upper abdominal pain, and upper abdominal pain that improves with eating. With a gastric ulcer, the pain may worsen with eating. The pain is often described as a burning or dull ache. Other symptoms include belching, vomiting, weight loss, or poor appetite. About a third of older people with peptic ulcers have no symptoms. Complications may include bleeding, perforation, and blockage of the stomach. Bleeding occurs in as many as 15% of cases.
Clarithromycin, sold under the brand name Biaxin among others, is an antibiotic used to treat various bacterial infections. This includes strep throat, pneumonia, skin infections, H. pylori infection, and Lyme disease, among others. Clarithromycin can be taken by mouth as a tablet or liquid or can be infused intravenously.
Helicobacter pylori, previously known as Campylobacter pylori, is a gram-negative, flagellated, helical bacterium. Mutants can have a rod or curved rod shape, and these are less effective. Its helical body is thought to have evolved in order to penetrate the mucous lining of the stomach, helped by its flagella, and thereby establish infection. The bacterium was first identified as the causal agent of gastric ulcers in 1983 by the Australian doctors Barry Marshall and Robin Warren.
Pantoprazole, sold under the brand name Protonix, among others, is a proton pump inhibitor used for the treatment of stomach ulcers, short-term treatment of erosive esophagitis due to gastroesophageal reflux disease (GERD), maintenance of healing of erosive esophagitis, and pathological hypersecretory conditions including Zollinger–Ellison syndrome. It may also be used along with other medications to eliminate Helicobacter pylori. Effectiveness is similar to other proton pump inhibitors (PPIs). It is available by mouth and by injection into a vein.
Esomeprazole, sold under the brand name Nexium [or Neksium] among others, is a medication which reduces stomach acid. It is used to treat gastroesophageal reflux disease, peptic ulcer disease, and Zollinger–Ellison syndrome. Its effectiveness is similar to that of other proton pump inhibitors (PPIs). It is taken by mouth or injection into a vein.
Rabeprazole, sold under the brand name Aciphex, among others, is a medication that decreases stomach acid. It is used to treat peptic ulcer disease, gastroesophageal reflux disease, and excess stomach acid production such as in Zollinger–Ellison syndrome. It may also be used in combination with other medications to treat Helicobacter pylori. Effectiveness is similar to other proton pump inhibitors (PPIs). It is taken by mouth.
Achlorhydria and hypochlorhydria refer to states where the production of hydrochloric acid in gastric secretions of the stomach and other digestive organs is absent or low, respectively. It is associated with various other medical problems.
A stool test is a medical diagnostic technique that involves the collection and analysis of fecal matter. Microbial analysis (culturing), microscopy and chemical tests are among the tests performed on stool samples.
Lansoprazole, sold under the brand name Prevacid among others, is a medication which reduces stomach acid. It is a proton pump inhibitor (PPI), used to treat peptic ulcer disease, gastroesophageal reflux disease, and Zollinger–Ellison syndrome. Its effectiveness is similar to that of other PPIs. It is taken by mouth. Onset is over a few hours and effects last up to a couple of days.
Giaconda is an Australian biotechnology company headquartered in Sydney. The company was founded in 2004 to commercialise a number of drug combinations developed by Professor Thomas Borody, a Sydney-based gastroenterologist.
This is a timeline of the events relating to the discovery that peptic ulcer disease and some cancers are caused by H. pylori. In 2005, Barry Marshall and Robin Warren were awarded the Nobel Prize in Physiology or Medicine for their discovery that peptic ulcer disease (PUD) was primarily caused by Helicobacter pylori, a bacterium with affinity for acidic environments, such as the stomach. As a result, PUD that is associated with H. pylori is currently treated with antibiotics used to eradicate the infection. For decades prior to their discovery, it was widely believed that PUD was caused by excess acid in the stomach. During this time, acid control was the primary method of treatment for PUD, to only partial success. Among other effects, it is now known that acid suppression alters the stomach milieu to make it less amenable to H. pylori infection.
Helicobacter pylori eradication protocols is a standard name for all treatment protocols for peptic ulcers and gastritis in the presence of Helicobacter pylori infection. The primary goal of the treatment is not only temporary relief of symptoms but also total elimination of H. pylori infection. Patients with active duodenal or gastric ulcers and those with a prior ulcer history should be tested for H. pylori. Appropriate therapy should be given for eradication. Patients with MALT lymphoma should also be tested and treated for H. pylori since eradication of this infection can induce remission in many patients when the tumor is limited to the stomach. Several consensus conferences, including the Maastricht Consensus Report, recommend testing and treating several other groups of patients but there is limited evidence of benefit. This includes patients diagnosed with gastric adenocarcinoma, patients found to have atrophic gastritis or intestinal metaplasia, as well as first-degree relatives of patients with gastric adenocarcinoma since the relatives themselves are at increased risk of gastric cancer partly due to the intrafamilial transmission of H. pylori. To date, it remains controversial whether to test and treat all patients with functional dyspepsia, gastroesophageal reflux disease, or other non-GI disorders as well as asymptomatic individuals.
Vonoprazan, sold under the brand name Voquezna among others, is a first-in-class potassium-competitive acid blocker medication. Vonoprazan is used in form of the fumarate for the treatment of gastroduodenal ulcer and reflux esophagitis, and can be combined with antibiotics for the eradication of Helicobacter pylori. It is a potassium-competitive acid blocker.
Bismuth subcitrate potassium is a bismuth salt used in combination with antibiotics and a proton pump inhibitor for the treatment of Helicobacter pylori infections.
Ranitidine bismuth citrate - drug, which has antisecretory and bactericidal action.

Vonoprazan/amoxicillin/clarithromycin, sold under the brand name Vonosap among others, is a co-packaged medication used for the treatment of Helicobacter pylori infection. It contains vonoprazan, a potassium-competitive acid blocker; amoxicillin, a beta-lactam antibiotic; and clarithromycin, a macrolide antibiotic.
