'''Bentiromide''' is a ] used as a screening test for ] ] insufficiency and to monitor the adequacy of supplemental pancreatic therapy. Bentiromide is not available in the United States or Canada; it was withdrawn in the US in October 1996.<ref name="Drugs.com">{{Drugs.com|cons|bentiromide}} on bentiromide.</ref> |

|
|
== Side effects == |
|
|
Headache and gastrointestinal disturbances have been reported in patients taking bentiromide.<ref name="Drugs.com" /> |
|
|
|
|
|
== Mechanism of action == |
|
|
Bentiromide is given by mouth as a noninvasive test. It is broken down by the pancreatic enzyme ], yielding ] (PABA). The amount of PABA and its ] excreted in the urine is taken as a measure of the chymotrypsin-secreting activity of the pancreas. |

It is synthesized by amide formation between ethyl ''p''-aminobenzoate and ''N''-benzoyl-tyrosine using ''N''-methyl-morpholine and ethyl chlorocarbonate for activation. The resulting L-amide is selectively hydrolyzed by sequential use of ] (]) and dilute acid to give bentiromide ('''4'''). |
