title: Evaluation of two forms of N-benzoyl-L-tyrosyl p-aminobenzoic acid in pancreatic function testing of dogs.
abstract: Plasma para-aminobenzoic acid (PABA) concentrations were compared in 12 dogs after oral administration of either a powdered suspension or a solution of N-benzoyl-L-tyrosyl-PABA. Peak PABA plasma concentrations were significantly higher at 30, 60 and 90 minutes after administration of the solution (P less than 0.05). As the solution may now be used as a clinical test, interpretation of the results by comparison with normal absorption curves obtained after administration of the suspension could contribute to a failure to diagnose canine exocrine pancreatic insufficiency.
