Omeprazole, a highly effective acid pump inhibitor, has been investigated most extensively in this context, and is markedly effective in eradicating H. pylori when combined with any two of clarithromycin, a nitroimidazole and amoxycillin.
Is tetracycline used for H. pylori?
Tetracycline has been used primarily in combination with other antibiotics for the eradication of H pylori. It is stable at a low pH and, like amoxicillin, has activity against H pylori as a topical agent, achieving concentrations in the gastric juice and mucosa much greater than the published MIC of H pylori.

Is there another treatment for H. pylori?
The Maastricht V/Florence Consensus Report recommends bismuth quadruple therapy, or fluoroquinolone-amoxicillin triple/quadruple therapy as the second-line therapy for H. pylori infection.
When do you treat H. pylori?
The overall consensus is that H. pylori should be eradicated as soon as possible and best before precancerous lesions are present. The 2007 Asia–Pacific Consensus Conference recommended that population-based screening and antibiotic treatment of H. pylori in high-risk regions should be performed [Fock et al.
Why are multiple antibiotics used for H. pylori?
pylori treatment usually includes several medicines. At least two of the medicines are antibiotics that help to kill the bacteria. The other medication causes the stomach to make less acid; lower acid levels help the ulcer to heal.
What is the pH of Helicobacter pylori?
The survival and replication cycle of Helicobacter pylori(H. pylori) is strictly dependant on intragastric pH, since H. pylorienters replicative phase at an almost neutral pH (6-7), while at acid pH (3-6) it turns into its coccoid form, which is resistant to antibiotics.
Can proton pump inhibitors increase intragastric pH?
On these bases, it is crucial to increase intragastric pH by proton pump inhibitors (PPIs) when an antibiotic-based eradicating therapy needs to be administered. Therefore, several tricks need to be used to optimize eradication rate of different regimens.
What is the first line of treatment for H. pylori?
First-line therapy for H. pylori infection includes clarithromycin triple therapy (clarithromycin, proton pump inhibitor [PPI], and amoxici …. Helicobacter pylori infection can lead to gastritis, gastric and duodenal ulcers, and gastric cancer. Consequently, complete eradication is the goal of therapy.

What is the sole class of antibiotics for treatment of H. pylorithat?
Fluoroquinolones are the sole class of antibiotics for treatment of H. pylorithat directly inhibit bacterial DNA synthesis. Resistance to fluoroquinolones occurs primarily by mutation in the genes for topoisomerase IV and gyrase[59].
What is triple therapy?
The standard triple therapy consists of a proton pump inhibitor, amoxicillin and clarithromycin, although many other regimens are used, including quadruple, sequential and concomitant therapy regimens supplemented with metronidazole, clarithromycin and levofloxacin.
Does sulphoraphane help with gastritis?
