Abstract
The invention relates to salts formed between basic H.sub.2 -receptor antagonists and a complex of bismuth with a carboxylic acid, and solvates of such salts, excluding salts in which the basic H.sub.2 -receptor antagonist is ranitidine. Examples of suitable carboxylic acids are citric acid and tartaric acid. Examples of basic H.sub.2 -receptor antagonists are cimetidine, sufotidine famotidine and nizatidine. The salts are useful in the treatment of gastrointestinal disorders, particularly gastroduodenal conditions. The salts show the antisecretory activity associated with the basic H.sub.2 -receptor antagonist together with antibacterial activity against Campylobacter pylori, and they also possess cytoprotective properties.
