| Additional Infomation |
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, an indicator and a reagent.
Bentiromide is a dipeptide that is used in the bentiromide test, which is a screening test for evaluating pancreatic exocrine function and monitoring the adequacy of supplemental pancreatic therapy. It is typically administered orally. Cases of headache and gastrointestinal disturbances have been reported with the use of bentiromide. Bentiromide is currently not available in the U.S. or Canada. Drug Indication Indicated as a screening test for exocrine pancreatic insufficiency and to monitor the adequacy of supplemental pancreatic therapy. Mechanism of Action Bentiromide is a peptide that is broken down in the pancreas by chymotrypsin. By determining the output of unchanged bentiromide in the urine following oral administration, it is possible to determine the sufficiency of pancreatic activity. Pharmacodynamics Bentiromide is a peptide used as a screening test for exocrine pancreatic insufficiency and to monitor the adequacy of supplemental pancreatic therapy. The amount of p-aminobenzoic acid and its metabolites excreted in the urine is the quantitative measure of the chymotrypsin-secreting activity of the pancreas. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (5.14 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (5.14 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 2.08 mg/mL (5.14 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
