Bentiromide is a medication that is used to diagnose small intestinal bacterial overgrowth (SIBO) in people with celiac disease. It works by releasing a marker into the small intestine that can be detected in the urine, allowing the doctor to measure the amount of bacteria present. Additionally, Bentiromide can help to reduce the symptoms of SIBO, such as abdominal discomfort, bloating, and flatulence. It is typically taken as a single dose of 1,000 mg, followed by collection of a urine sample two hours later.
Bentiromide is a diagnostic agent, not a medication used for treatment. It plays a specific role in testing pancreatic function. Here's a breakdown of its use:
Function: Bentiromide is used in the bentiromide test, a non-invasive screening test to assess exocrine pancreatic function. The exocrine pancreas is responsible for producing enzymes that aid digestion.
Mechanism of action: Bentiromide is a synthetic peptide that mimics a natural substrate for the enzyme chymotrypsin, which is produced by the pancreas. When taken orally, bentiromide is broken down by chymotrypsin in the small intestine, releasing a component called p-aminobenzoic acid (PABA).
Test procedure:
- The patient ingests a single oral dose of bentiromide.
- Urine is collected over a specific period, typically 6 hours, and the amount of PABA and its metabolites are measured.
Interpretation:
- Healthy individuals: A higher level of PABA indicates good pancreatic function and efficient breakdown of bentiromide by chymotrypsin.
- Low PABA levels: May suggest insufficient production of chymotrypsin, potentially indicating exocrine pancreatic insufficiency (EPI).
Important points:
- Bentiromide is not a treatment: It is a diagnostic tool to aid healthcare professionals in assessing pancreatic function, not a treatment for any medical condition.
- Limitations: The bentiromide test is not definitive for diagnosing EPI. Other tests and clinical evaluation are often necessary for confirmation.
- Not widely available: Bentiromide is no longer available in some countries like the US and Canada due to the emergence of alternative and potentially more sensitive tests for EPI.
