Carbenoxolone patients with gastric ulcers. A double-blind trial.

Carbenoxolone was compared with placebo in a randomised double-blind study involving 40 patients with gastric ulcer (20 each in the treated and placebo groups). The evaluation was based on eight variables. The endoscopic findings on completion of 4 or 6 weeks of treatment, revealed greater improvement in response to carbenoxolone than to placebo. The difference was statistically significant at the previously fixed level of significance of p less than 0.05. The plasma potassium level fell significantly in the treated group but the actual reduction of 7% was slight. No statistically significant differences were measured in any of the other variables, i.e. plasma sodium, SGOT, SGPT, systolic and diastolic blood pressure, bodyweight, or oedema formation.
