Pharmacotherapeutic group: Alimentary tract and metabolism
ATC code: A02BX02
The action of Antepsin is non-systemic as the drug is only minimally absorbed from the gastro-intestinal tract. The small amounts that are absorbed are excreted primarily in the urine. Antepsin exerts a generalised cytoprotective effect by preventing gastro-intestinal mucosal injury.
Studies in humans and animal models show that Antepsin forms an ulcer adherent complex with the proteinaceous exudate of the ulcer site. This property enables Antepsin to form a protective barrier over the ulcer lesion giving sustained protection against the penetration and action of gastric acid, pepsin and bile.
Studies both in humans and animals demonstrate that Antepsin protects the gastric mucosa against various irritants such as alcohol, acetylsalicyclic acid and sodium taurocholate.
Antepsin also directly inhibits pepsin activity and absorbs bile salts. It has only weak antacid activity. It does not alter gastric emptying time, nor normal digestive function. Antepsin has no demonstrated pharmacological effect on the cardiovascular or central nervous systems.
In the literature, there are limited clinical data on the use of sucralfate in children, mainly for stress ulcer prophylaxis, reflux oesophagitis, and mucositis. The dose used in these studies was 0.5–1 g four times a day, depending on the children’s age and the severity of the underlying disease, and was applied without major safety concerns. In view of the limited data, use of sucralfate in children under 14 years of age is currently not recommended.
Sucralfate is only minimally absorbed from the gastro-intestinal tract. The small amounts that are absorbed are excreted primarily in the urine. Absorption of aluminium from sucralfate may be increased in patients on dialysis or with renal dysfunction (see also “other special warnings and precautions”).
There was no evidence of carcinogenesis in mice and rats receiving oral sucralfate in dosages of up to 1 g/kg daily (12 times the usual human dosage) for 2 years. In animal studies there was no effect evidence of impaired fertility. The effect of sucralfate on human fertility is not known.
