Pylori ) is considered a main causative organism of gastric ulcers, gastric cancer and duodenal ulcers. The current treatment relies on a combination of antimicrobial agents and acid suppressant agents, but the eradication effect is not satisfactory. To clarify the concentration of antibiotics at the lesion site, we investigate the clinical efficacy and drug tissue distribution of the combination therapy of furazolidone and tetracycline in eradicating H. Pylori.</p><p><strong>Materials and methods: </strong>Patients with H. pylori infection (n = 60) were randomized to either group A or B. Bismuth potassium citrate capsules 220 mg, omeprazole enteric-coated capsules 20 mg, amoxicillin capsules 1000 mg, each twice per day, and furazolidone tablets 500 mg were administered to group A. Group B was treated with bismuth potassium citrate capsules 220 mg, omeprazole enteric-coated capsules 20 mg, amoxicillin capsules 1000 mg, and tetracycline tablets 500 mg each twice per day for 2 weeks. The serum and gastric juice, gastric antrum, gastric horn, and gastric body samples were taken under a gastroscope on the 14th day. The antimicrobial concentrations in serum and tissue samples were determined by high-performance liquid chromatography.</p><p><strong>Results: </strong>In the negative group of furazolidone, the concentrations of gastric antrum, gastric body, and gastric angle were significantly higher than those in the positive group ( P = 0.017, 0.015, and 0.028). The concentrations of furazolidone in gastric fluid, gastric antrum, gastric angle, and gastric body were ∼421 times, 82 times, 17 times, and 51 times higher than those in serum, respectively. The concentrations of tetracycline in the serum and gastric angle of the tetracycline negative group were significantly higher than those in the positive group ( P = 0.036 and 0.042), and the tetracycline concentrations in the gastric horn and gastric body were about 4 and 6 times higher than those in the serum, respectively. The concentration of amoxicillin in group B was higher than that in group A, especially in serum, gastric juice, gastric angle, and gastric body ( P < 0.05).</p><p><strong>Conclusion: </strong>Furazolidone is mainly concentrated and sequentially distributed in gastric juice, gastric antrum, and gastric body tissue, and tetracycline is mainly distributed in serum, gastric angle, and gastric body, whereas amoxicillin is mainly distributed in serum, gastric juice, gastric angle, and gastric body. Improving the concentration and tissue distribution of antibacterial drugs in the human gastric mucosa is the key to ensuring the ideal eradication rate of quadruple therapy.</p>","PeriodicalId":15457,"journal":{"name":"Journal of clinical gastroenterology","volume":" ","pages":"70-76"},"PeriodicalIF":2.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141751835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
