During continuous intravenous pentagastrin to 11 subjects for 60 min, the mean concentration and secretion rates per minute rose to 24 microg/ml and 122 microg/min at 60 min; the proportion of pepsin 1 to total pepsin was 2.8% in basal secretions increasing to 7.8% in the 60 to 70-min samples.

The authors speculated that pepsin and bile acids in weakly acidic conditions could be relevant for Barrett's transformation.42 They suggested that proteolytic activity of pepsin is maintained up to pH 5.5 and denaturation occurs at pH > 7.43 Furthermore, bile acids can impair esophageal mucosal integrity also in a weakly acidic environment.32 Therefore, the authors suggested that regression of intestinal metaplasia with long-term PPI therapy would not be expected with persistence of weakly acidic containing bile acids, and in fact it has been reported that regression can occur in only 30% of short-segment Barrett's esophagus patients.44

This drug, a basic amino salt of sucrose octosulphate , acts by binding to the protein of the matrix of the ulcer crater, thus coating the ulcer against the aggressive principle of acid-pepsin and probably also by a cytoprotective effect.
