Randomized double-blind placebo-controlled study of drugs with anti-ulcer action and their use in associated pathology

The effect of lithium preparations (lithium carbonate, lithium oxybutyrate), calcium channel blocking agents (verapamil, nifedipine), beta 2-adrenoagonist (salbutamol), cromolyn sodium and cimetidine on clinical efficacy and frequency of ulcer cicatrization was assessed in 201 patients (33 women, 168 men) with endoscopically verified stomach ulcer (52 patients) and duodenal ulcer (166 patients) during treatment for 4 weeks as compared to placebo and standard antiulcerative therapy (cholinolytics, antacids and reparents). All the tested drugs (excluding cromolyn sodium) significantly increased as compared to placebo the frequency of ulcer cicatrization (p less than 0.001 in the use of lithium preparations and cimetidine; p less than 0.01 in the use of salbutamol and verapamil; p less than 0.05 in the use of nifedipine). The effect of lithium preparations and cimetidine exceeded that of standard antiulcerative multimodality therapy.
