MedKoo CAT#: 317312

CAS#: 37106-97-1

Description: Bentiromide is a peptide used as a screening test for exocrine pancreatic insufficiency and to monitor the adequacy of supplemental pancreatic therapy. It is given by mouth as a noninvasive test. The amount of 4-aminobenzoic acid and its metabolites excreted in the urine is taken as a measure of the chymotrypsin-secreting activity of the pancreas.
