Gastritis Treatment Guidelines

First-Line Treatment Options

The American College of Gastroenterology recommends high-potency proton pump inhibitors (PPIs) as first-line treatment for gastritis, with options like esomeprazole or rabeprazole (20-40 mg twice daily) being most effective for symptom relief and healing 1
Recommended PPI options and dosages include rabeprazole: 20 mg twice daily, esomeprazole: 20-40 mg twice daily, and lansoprazole: 30 mg twice daily 1
PPIs should be taken 30 minutes before meals for optimal effectiveness 1

Bismuth quadruple therapy for 14 days is the preferred first-line treatment for H. pylori-associated gastritis due to increasing antibiotic resistance 1
Concomitant 4-drug therapy is an alternative when bismuth is unavailable 1
Triple therapy options should be guided by local resistance patterns 1
Higher-potency PPIs improve H. pylori eradication rates 1
Testing for H. pylori should be performed using non-invasive tests such as urea breath test or monoclonal stool antigen tests 1
Antibiotics in the "Access group" (amoxicillin, tetracycline, and metronidazole) have lower resistance potential 2
Eradication therapy should be administered for 14 days to maximize effectiveness 2
H. pylori eradication provides a significant improvement in symptom resolution compared to placebo 3

The American College of Gastroenterology recommends using the lowest effective NSAID dose for the shortest duration to minimize risk 1
Add PPI therapy for gastroprotection in high-risk patients taking NSAIDs 1
Consider H. pylori eradication before starting long-term NSAID therapy 1
Misoprostol reduces NSAID-associated gastric ulcers by 74% but has side effects including diarrhea and abdominal pain 1

Antacids provide rapid, temporary relief of symptoms and can be used on-demand for breakthrough symptoms 1
For patients with residual symptoms after successful H. pylori eradication, full-dose PPI therapy is recommended 1

Inadequate PPI dosing and premature discontinuation of treatment should be avoided 1
Failure to address H. pylori infection when present should be avoided 1
Relying solely on symptom resolution without confirming H. pylori eradication should be avoided 1
Insufficient duration of antibiotic therapy for H. pylori (should be 14 days) should be avoided 2
Confirm H. pylori eradication after treatment with non-invasive testing 1
Gradual improvement of symptoms with fluctuations is expected with appropriate treatment 1
For persistent symptoms despite appropriate therapy, consider endoscopic evaluation to rule out other causes 1
