Abstract
Pharmaceutical compositions comprising mixtures of a histamine H.sub.2 -receptor antagonist such as cimetidine or ranitidine and sodium polyacrylate in a specified range of ratios have been found to exhibit synergistic effects in an in vivo test model for anti-ulcer or mucosal-protecting agents. Pharmaceutical compositions comprising mixtures of a histamine H.sub.2 -receptor antagonist such as cimetidine or ranitidine and sodium polyacrylate in the range of ratios are described for use in the treatment of gastritis or of gastro-duodenal ulcers. In a modification in the mixtures the sodium polyacrylate may be replaced wholly or in part by potassium or ammonium polyacrylate.
