A Two Week Nitazoxanidebased Quadruple Regimen

Overview

Helicobacter pylori (H. pylori) infection is a global health problem as it is associated with peptic ulcers, chronic gastritis, duodenitis, and stomach cancer. Therefore, the eradication of the pathogen is of critical importance to reduce H. pylori-related complications . However, due to increasing antibiotic resistance, eradication of Helicobacter pylori has become more challenging. With a great decline in the eradication rate of standard triple therapy for Helicobacter pylori to below 70% in many countries. Treatment with triple therapy, which is the most frequently recommended, fails to eradicate H. pylori in approximately 20% of cases .

Designing a new rescue regimen that achieves greater than 85% eradication rate is an important target of current research. Unfortunately, the most frequently used "rescue" or "salvage" therapy is bismuth quadruple therapy consisting of a proton pump inhibitor (PPI), tetracycline, metronidazole, and bismuth \[11\]. This rescue therapy is inexpensive, and relatively effective with average eradication rate of 70% when used as second-line therapy. However, disadvantages of bismuth based quadruple therapy include the large daily number of pills (sometimes exceeding 18 pills), increased dosing frequency (four times daily), and frequent side effects.
