Helicobacter pylori eradication--evaluation of triple therapy containing omeprazole.
BACKGROUND
There is a need to develop alternative regimen(s) for treating Helicobacter pylori infection because of problems of drug compliance, side-effects and resistance with the conventional regimen consisting of bismuth, metronidazole and an antibiotic.


OBJECTIVE
To compare prospectively the efficacy of conventional triple therapy (bismuth subcitrate 120 mg QID, amoxycillin 500 mg QID and metronidazole 400 mg TID for 2 weeks with one containing omeprazole (20 mg OD), bismuth subcitrate and amoxycillin (regimen B).


METHODS
Sixty two consecutive patients with H pylori infection associated with antral gastritis and/or duodenal ulcer were randomized to two treatment groups and re- evaluated after completion of 2 weeks of therapy and then after a further 4 weeks for eradication of H pylori, ulcer healing and drug side-effects.


RESULTS
Regimen B resulted in higher H pylori eradication rate as compared to regimen A (76.7% vs 63.3%, better ulcer healing rate (90.9%, vs 70.6%), lesser side-effects (10.0% vs 36.7%) and better drug compliance (100% vs 93.3%). The difference between the two regimens was significant (p < 0.05) only in respect to side-effects.


CONCLUSIONS
For H pylori eradication, omeprazole, bismuth and amoxycillin combination for 2 weeks is as effective as the conventional therapy and is better tolerated.
