"Ulcosilvanil"--an inhibitor of carbonic anhydrase--associated with adrenergic beta-blockers in the treatment of duodenal ulcers.

Knowing the in vivo inhibitory effect of the beta-adrenoreceptor antagonists on gastric mucosa carbonic anhydrase and the high clinical efficacy of "Ulcosilvanil" in the healing of gastric and duodenal ulcers, the authors combined propranolol with smaller doses of "Ulcosilvanil" in 925 active duodenal ulcer patients, divided into four groups. The first 236 patients were treated with small doses of "Ulcosilvanil" (20 mg/kg b.w.
