Effectiveness of cisapride in gastric ulcer. Results of a double-blind randomized trial versus ranitidine and versus cisapride plus ranitidine.
Among the factors involved in the pathogenesis of gastric ulcer, the reduced clearing capacity of the stomach seems to play an important role. On this basis, cisapride, which improves gastrointestinal motility, enhances gastric emptying, and prevents duodenogastric reflux, may be effective in the treatment of the gastric ulcer. We randomly allocated 60 consecutive patients, with uncomplicated antral gastric ulcer (diameter 5-25 mm), into three groups of treatment: cisapride 20 mg b.i.d. (C), ranitidine 150 mg b.i.d. (R), cisapride 20 mg b.i.d. + ranitidine 150 mg b.i.d. (C+R). Endoscopic examination with biopsy specimens was performed on admission, after 4 weeks and (if ulcer not healed) after 8 weeks of therapy. Three patients were lost to follow-up (two in C and one in C+R), and three were withdrawn, due to malignant ulcer (one case in R) or to side effects (one case of diarrhea in C, one case of headache in C+R). Healing rates at 4 weeks were 41.1% in C, 52.6% in R, and 50.0% in C+R; at 8 weeks they were 88.2% in C, 89.4% in R, and 94.4% in C+R. Though the lack of a placebo arm makes final considerations difficult, the results were similar in all three groups, with no evident differences. In conclusion, therapy with cisapride appears as effective as H2-blocker alone or combined treatments in healing benign gastric ulcer.
