Fate of Orally Ingested Enzymes in Pancreatic Insufficiency

Abstract
To assess the fate and efficacy of orally ingested enzymes in pancreatic insufficiency, we administered pancreatin to six patients by two schedules — eight tablets with a standard meal or two tablets hourly — and in six normal controls, quantified duodenal enzyme activity and related inactivation of ingested enzymes to gastric and duodenal pH; in the six patients we measured malabsorption by fecal balance studies.
