The Efficacy and Safety of Ilaprazole/Doxycycline-based Bismuth-containing Quadruple Therapy on Hp Infected Duodenal Ulcers

Brief description of study

Helicobacter pylori (Hp) infection is one of the important causes of gastrointestinal diseases, including gastritis, peptic ulcer, and malignancies, nd the eradication of Hp can effectively cure or prevent these diseases. Now, owing to the increasingly serious antibiotic resistance, Hp eradication rate is, however, becoming decreased. In order to improve the eradication rate of Hp, clinicians pay great attention to choose more effective treatment.

Ilaprazole Enteric-Coated Tablets is a new generation of proton pump inhibitor (PPI). Previous research found that Ilaprazole had a more prolonged half-life and higher suppression of gastric acid secretion. In addition, its metabolism is not significantly influenced by CYP2C19, compared to the available PPIs. Doxycycline is in the tetracycline antibiotic class, has a stronger antibacterial force than tetracycline and its antibacterial spectrum is basically the same as tetracycline and doxycycline, so far, it is not widely used. Preliminary observations showed that Ilaprazole/Doxycycline-based quadruple therapy was effective in treating Hp infection, with less adverse reactions and good compliance with patients.

In this study, a multi-center, randomized, parallel controlled trial will be conducted in 10 hospitals in Hunan Province, China, to observe the clinical efficacy and safety of the Bismuth-containing quadruple therapy with Ilaprazole, Doxycycline, Furazolidone and Bismuth Potassium Citrate in the treatment of Hp infected duodenal ulcer. It is expected to complete 240 effective cases, including 120 cases in the experimental group and 120 cases in the control group.
