摘要
Sucralfate attains a healing rate of about 79% for duodenal ulcer in 4 weeks, which is similar to the effects of cimetidine and ranitidine. Whereas, cigarette smoking significantly affects duodenal ulcer healing by acid-reducing agents, the healing rates of smokers and non-smokers treated with sucralfate or colloidal bismuth are indistinguishable, suggesting an inherent advantage through the cytoprotective mechanisms of these agents. The 12-month relapse curves for duodenal ulcers initially healed with sucralfate and colloidal bismuth subcitrate closely overlap each other and are significantly lower than the curves for the histamine H-2-receptor antagonists. These findings cannot be accounted for by clearance of Helicobacter pylori, on which sucralfate has little effect. Preliminary evidence suggests that the use of acid-reducing agents results in up-regulation of the parietal cells and may help to explain the differences in relapse rates. Sucralfate is superior to placebo and comparable to H-2 antagonists in the prevention of duodenal ulcer recurrence.
