Cimetidine and ulcers.

Cimetidine for ulcers recurring after gastric surgery.

Ultrastructural changes in gastric ulcers after bicitropeptide and cimetidine treatment.

Ultrastructural studies were conducted on biopsy specimens taken by endoscopy from the edge of gastric ulcers in the distal part of the stomach of 9 patients before and after treatment with either bicitropeptide or cimetidine. Marked depletion of mucin granules in the mucous epithelial cells and the pyloric gland cells was found in all patients and there was morphological evidence of a block in...

Effects of cimetidine on the healing and recurrence of duodenal ulcers and gastric ulcers.

The effects of cimetidine on the healing and recurrence of duodenal ulcers and gastric ulcers were compared. The extent of the acid secreting areas was examined by the endoscopic Congo red methylene blue test. Using the extent of acid secreting areas gastric ulcers were classified into ulcers with and without extensive acid secreting areas. Duodenal ulcers were all associated with extensive aci...

Treatment of 'cimetidine-resistant' chronic duodenal ulcers with ranitidine or cimetidine: a randomised multicentre study.

Forty patients with endoscopically proven persistent duodenal ulcer who had been treated for six weeks with cimetidine (1 g/day) were randomly allocated to receive a further six weeks' treatment with cimetidine (1 g/day) or ranitidine (300 mg/day). Ulcers healed in 12 of 19 patients given cimetidine (63%) and in 13 of 21 given ranitidine (62%); two patients on cimetidine and two on ranitidine d...
