Abstract
Benzimidazole derivatives of the general formula [I] are provided: ##STR1## wherein R.sup.1 is hydrogen, methyl or methoxy, and R.sup.2 and R.sup.3 each is hydrogen or methyl, at least one of R.sup.1, R.sup.2 and R.sup.3 being a member other than hydrogen. The benzimidazole derivatives exhibit an excellent activity of inhibiting the potassium ion-dependent adenosine triphosphatase, as well as a good stability during storage. Therefore, the benzimidazole derivatives are usable for the treatment of gastric and/or duodenal ulcers.
