What is Bentiromide?

Plain description, key identifiers and synonyms

Bentiromide is the dipeptide obtained by condensation of N-benzoyl-L-tyrosine with 4-aminobenzoic acid. Used as a noninvasive screening test for exocrine pancreatic insufficiency and to monitor the adequacy of supplemental pancreatic therapy, it is given by mouth: 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. It has a role as a diagnostic agent, a reagent and an indicator.
