OBJECTIVES: Simpler, effective therapies to treat Helicobacter pylori infection are greatly needed. Omeprazole co-therapy apparently enhances effectiveness of some antimicrobials. Our objective in this study was to determine whether the apparent additional benefit provided by omeprazole to amoxicillin therapy could be equaled by a high dose of ranitidine plus sodium bicarbonate.
METHODS: In a prospective randomized trial, we tested 1 g amoxicillin b.i.d. with either omeprazole 20 mg b.i.d., or high dose ranitidine (900 and 1800 mg) plus sodium bicarbonate tablets 650 t.i.d. (with meals) for 14 day.
RESULTS: Fifty-two patients with documented H. pylori infection and peptic ulcer completed therapy. The cure rate with omeprazole and amoxicillin was poor (46%), with the 95% confidence interval (CI) = 25-67%. Ranitidine plus sodium bicarbonate was also poor (39% cure) with the 95% CI = 21.5-59% (p > 0.57). Average compliance was more than 92% for all three groups. Side effects were experienced in only two patients (stomatitis and mild diarrhea).
CONCLUSION: Neither the omeprazole nor ranitidine plus bicarbonate plus amoxicillin therapies used here can be recommended for treatment of H. pylori infection.
