ABSTRACT
Twelve healthy volunteers were given a single sucralfate tablet (1 gm) orally. For 60 min after ingestion they were examined endoscopically for the localization and disintegration of the tablet in the stomach, and biopsies were taken to determine the effect of sucralfate on the histology and ultrastructure of the normal gastric mucosa. After ingestion, the sucralfate tablet had disintegrated and firmly adhered to a relatively small mucosal area of the greater curvature covering 5 +/- 2 and 7 +/- 2 cm2 at 15 and 30 minutes, and 9 +/- 3 cm2 at 60 minutes after drug ingestion. Histologic and ultrastructural examination of the mucosa in direct contact with sucralfate revealed distinct changes in the surface epithelial cells mucus release, vacuolization, and exfoliation of some of the cells. Endoscopy offers a unique opportunity for the study of gastroduodenal effects and disposition of orally administered drugs.
