A combination of three antibiotics (omeprazole, clarithromycin, and amoxicillin) successfully eliminated H. pylori bacteria in 90.6% of patients with stomach ulcers, according to a real-world study of 870 patients. When doctors added bismuth, probiotics, or rebamipide to the standard treatment, success rates increased to 97%, and patients reported significant relief from stomach pain. Gram Research analysis shows that this ready-made combination treatment is highly effective and well-tolerated, with 93.7% of patients satisfied with their results.
Researchers tested a combination of three antibiotics (omeprazole, clarithromycin, and amoxicillin) to treat H. pylori, a bacteria that causes stomach ulcers and pain. In a real-world study of 870 patients, the standard treatment worked 90.6% of the time, but when doctors added bismuth, probiotics, or a special gut-healing compound called rebamipide, success rates jumped to 97%. Patients reported significant relief from stomach pain and were highly satisfied with the treatment. According to Gram Research analysis, this shows that combining proven antibiotics with additional gut-supporting treatments offers the best chance of eliminating this troublesome bacteria.
Key Statistics
A real-world observational study of 870 H. pylori-positive patients found that standard triple therapy with omeprazole, clarithromycin, and amoxicillin achieved a 90.6% eradication rate, with success rates reaching 97% when bismuth, probiotics, or rebamipide were added to the regimen.
In the 2026 PAMIR observational program involving 870 patients, physicians rated treatment efficacy and tolerability as ‘very good’ or ‘good’ in 93.3% of cases, and 93.68% of patients reported complete or substantial satisfaction with H. pylori eradication therapy.
Adding a synbiotic complex containing Lactobacillus acidophilus, Lactobacillus rhamnosus, and Bifidobacterium lactis to standard triple therapy increased H. pylori eradication rates to 96.82% in a study of 870 real-world patients.
The 2026 PAMIR study demonstrated that treatment with standard triple therapy significantly reduced abdominal pain scores on the Gastrointestinal Symptom Rating Scale, with enhanced regimens showing superior outcomes in nearly all measured parameters.
The Quick Take
- What they studied: Whether a combination of three antibiotics (omeprazole, clarithromycin, and amoxicillin) could successfully eliminate H. pylori bacteria that causes stomach ulcers, and whether adding extra treatments like bismuth or probiotics made it work better.
- Who participated: 912 patients with stomach ulcers caused by H. pylori bacteria (404 men and 508 women, average age 44 years). Most were from real doctor’s offices, not just research hospitals. 870 patients completed the full treatment program.
- Key finding: The standard three-antibiotic combination cured H. pylori in 90.6% of patients. When doctors added bismuth, probiotics, or rebamipide, the cure rate jumped to 97%, meaning nearly all patients got better. Patients also reported much less stomach pain after treatment.
- What it means for you: If you have H. pylori and stomach ulcers, this treatment combination has a very good chance of eliminating the bacteria. Adding probiotics or bismuth to the standard treatment may improve your chances of success. However, always follow your doctor’s specific recommendations, as individual cases vary.
The Research Details
This was an observational program, meaning researchers watched how the treatment worked in real doctor’s offices rather than in a controlled laboratory setting. Doctors treated 912 patients with H. pylori using a ready-made combination pill called Pylobact® AM containing three antibiotics. Some patients received just the standard three antibiotics (538 patients), while others received the three antibiotics plus additional treatments like bismuth, probiotics, or rebamipide (332 patients). Researchers measured success by testing whether the bacteria was gone using breath tests, stool tests, or stomach biopsies. They also asked patients about their symptoms using a standard questionnaire and asked both patients and doctors to rate how well the treatment worked.
The study tracked patients’ stomach pain, bloating, and other digestive symptoms before and after treatment using a validated symptom scale. Doctors and patients rated treatment satisfaction on a five-point scale. The researchers compared how well the three different treatment approaches worked in real-world conditions where patients were taking the medicine at home, not in a hospital setting.
Real-world studies like this are important because they show how treatments actually work when regular patients take them at home, not just in perfect laboratory conditions. This study was large enough (870 patients) to give reliable answers about whether adding extra treatments to standard antibiotics really helps. The study also measured what matters most to patients, whether their stomach pain went away and whether they were satisfied with the treatment.
This study has several strengths: it included a large number of patients (870), used multiple methods to confirm H. pylori was actually eliminated (breath tests, stool tests, and biopsies), and measured both doctor and patient satisfaction. The study was conducted in real medical practices, making results applicable to typical patients. However, this was an observational study rather than a randomized controlled trial, meaning researchers didn’t randomly assign patients to different treatments, which could introduce some bias. The study doesn’t clearly explain why some patients received additional treatments beyond the standard three antibiotics.
What the Results Show
The standard three-antibiotic treatment (omeprazole, clarithromycin, and amoxicillin) successfully eliminated H. pylori in 90.6% of patients. This is a very good success rate. When doctors added bismuth, probiotics, or rebamipide to the standard treatment, the success rate increased to 97.03%, meaning nearly all patients were cured. When the treatment included bismuth combined with a special probiotic blend called Floriose, the success rate was 96.82%.
Beyond just killing the bacteria, patients experienced significant relief from their stomach symptoms. Stomach pain scores on the symptom questionnaire dropped substantially during treatment. At the end of treatment, doctors rated the effectiveness and tolerability as “very good” or “good” in 93.3% of cases. This means the medicine worked well and patients tolerated it without serious side effects.
Patient satisfaction was high: 93.68% of patients reported being completely or mostly satisfied with their treatment. This suggests that not only did the medicine work, but patients felt the experience was positive overall. The ready-made combination pill format (Pylobact® AM) likely helped because patients didn’t have to remember to take multiple separate medications, which improved their compliance with the treatment plan.
The study found that adding probiotics, beneficial bacteria that support gut health, to the standard treatment improved outcomes. The specific probiotic strains used (Lactobacillus acidophilus, Lactobacillus rhamnosus, and Bifidobacterium lactis) combined with inulin and B vitamins showed promise. Adding bismuth, a mineral compound that has been used for stomach problems for decades, also boosted success rates. Rebamipide, a medication that helps protect and heal the stomach lining, contributed to better outcomes when combined with antibiotics. The fact that adding these treatments improved success from 90.6% to 97% suggests they work together synergistically, meaning they enhance each other’s effectiveness.
The 90.6% success rate for standard triple therapy with these three antibiotics is consistent with what medical research has shown in other studies. The improvement to 97% when adding bismuth and probiotics is notably better than many previous studies reported. This suggests that the combination approach may represent an advance in H. pylori treatment. The high patient satisfaction and symptom improvement align with other research showing that successful H. pylori eradication leads to significant relief from ulcer-related pain and digestive symptoms.
This study was observational rather than a randomized controlled trial, meaning researchers didn’t randomly assign patients to different treatment groups. This could introduce bias because patients who received additional treatments might have been sicker or more motivated to get better. The study doesn’t clearly explain why some patients received extra treatments and others didn’t. The study was conducted in one region (appears to be Russia based on the journal), so results might not apply equally to all populations. The study doesn’t provide detailed information about side effects or adverse reactions, only that tolerability was rated as good. Long-term follow-up data (beyond the treatment period) isn’t described, so we don’t know if the cure was permanent.
The Bottom Line
If you have H. pylori infection with stomach ulcers, the standard three-antibiotic combination (omeprazole, clarithromycin, and amoxicillin) is effective and should be your first choice. Strong evidence supports this approach with a 90.6% success rate. If your doctor recommends adding bismuth, probiotics, or rebamipide to boost effectiveness, this appears beneficial based on this research showing 97% success rates. Moderate evidence supports these additions. Take the complete course of antibiotics exactly as prescribed, even if you feel better, to ensure the bacteria is completely eliminated. Follow up with your doctor to confirm the bacteria is gone using appropriate testing.
This research is most relevant for people diagnosed with H. pylori infection, especially those with active stomach ulcers or a history of ulcers. People with chronic stomach pain, bloating, or digestive problems who test positive for H. pylori should discuss this treatment with their doctor. This is less relevant for people without H. pylori infection or those without stomach symptoms. Pregnant women and people with certain allergies to these antibiotics should discuss alternative treatments with their doctor.
Most patients in this study completed treatment within a standard course (typically 10-14 days for triple therapy). Symptom improvement, particularly stomach pain relief, occurred during the treatment period. Complete confirmation that H. pylori is eliminated requires testing 4 weeks or more after finishing antibiotics. Most patients should expect to feel significantly better within 1-2 weeks of starting treatment, with full healing of ulcers taking several weeks to months.
