Bentiromide is primarily used in medical diagnostics to assess pancreatic function. It is administered orally and serves as a substrate for the enzyme chymotrypsin, which is produced by the pancreas. After ingestion, bentiromide is broken down in the small intestine by chymotrypsin, releasing a compound called para-aminobenzoic acid (PABA). PABA is then absorbed into the bloodstream and excreted in the urine. By measuring the amount of PABA in the urine over a specific period, healthcare providers can evaluate the exocrine function of the pancreas. This test is particularly useful in diagnosing conditions such as chronic pancreatitis or cystic fibrosis, where pancreatic enzyme activity may be impaired. Bentiromide's role in this diagnostic process makes it a valuable tool in identifying and managing pancreatic disorders.
