Enzymic activities of commercial preparations of pancreatic enzymes.

The enzymic activities of 20 commercial pancreatic extracts have been measured by standard (F.I.P.) methods of assay and the activities have been compared with a standard preparation of pancreatin supplied by the British Pharmacopoeia Commission. A wide range of enzymic activities was found. The tabulated cost per unit of enzymic activities provides a guide to one aspect of the potential therapeutic efficacy of pancreatic extracts in the treatment of pancreatic exocrine insufficiency.
