    Abstract:
    BACKGROUND: The inhibition of H+/K(+)-ATPase (proton pump) of gastric parietal cells by substituted benzimidazoles represents a new therapeutic approach in conditions connected with hypersecretion of hydrochloric acid. Pantoprazol is the newest member of this group of drugs. Monotherapy of duodenal ulcer with pantoprazole or ranitidine was evaluated in terms of healing rate, tolerance and compliance. METHODS AND RESULTS: A double-blind, parallel-group comparing study (double dummy technique) of treatment florid duodenal ulcer (diameter 5-20 mm) was performed in 95 subjects (age 18-74 years). The active substances were either pantoprazole (40 mg before breakfast-47 subjects) or ranitidine (300 mg before bedtime-48 subjects). The average diameter of the ulcer and subjective complaints before treatment were comparable in both groups. After 2 weeks of pantoprazole therapy 88.5% of ulcers (a) and 87.2% patients (b) were cured, whereas the corresponding values in the ranitidine series amounted to 66% (a) and 62.5% (b) only (p = 0.006 for both (a) and (b)). The rate of healing in relative values of reducing the ulcer size was significantly higher after 2 weeks of pantoprazole therapy (p = 0.026 (a) and 0.0027 (b)). All ulcers healed after 4 weeks of this regimen. The difference between the pantoprazole and ranitidine series after 4 weeks was closely above the 5% level of significance (p = 0.589 for (a) and 0.0588 for (b) respectively). This was due to the low number of patients in both groups at this time interval, particularly in the pantoprazole group. Pain during day-time and regurgitation were observed significantly more frequently after ranitidine therapy. The compliance was very good and practically no adverse effects of pantoprazole therapy were observed. CONCLUSIONS: The healing rate of duodenal ulcer with pantoprazole monotherapy (40 mg before breakfast) was significantly higher than with ranitidine (300 mg before bedtime). The compliance of patients and the tolerance of pantoprazole were very good and its administration was not associated with any side-effects.
