Biorelevant Experiment

Biorelevant Solubility

  • Use Biorelevant Mini Prep Kits with Biorelevant Solubility Filters to conduct standardized equilibrium solubility experiments rapidly and efficiently 

  • Prepare media freshly with mini vials of powder and mini bottles of buffer concentrate

  • In vitro results help provide an understanding of how much drug dissolves in vivo within gastrointestinal fluids in both fasted (FaSSGF and FaSSIF) and fed (FeSSIF) states

  • Results enable you to understand oral drug developability of a drug candidate 

  • Very small quantities (less than 1mg) of drug candidate required for each timepoint

Background

Establishing the biorelevant equilibrium solubility of a drug candidate can help you understand a drug's in vivo behaviour and absorption potential. Specifically, establishing a drug candidate's biorelevant solubility is crucial for understanding its potential to be delivered orally. Biorelevant equilibrium solubility is the first step towards guiding and selecting potential formulation strategies for a drug product.

Biorelevant equilibrium solubility test results can enable developers to:

•    Estimate how much drug candidate is likely to dissolve within the gastrointestinal fluids
•    Identify potential developability challenges such as poor absorption or reason for food effects 
•    Reveal potential oral developability

How to conduct a Biorelevant Equilibrium Solubility Test

                                                       

1) Add drug candidate to biorelevant medium                  2) Insert filter housing into vial                             3) Incubate and collect samples. Analyse at 03h, 06h and 24h

*Determine the solubility of a drug candidate in the selected biorelevant medium by using Biorelevant Solubility Filters (available below)

*Dilute biorelevant solubility samples and analyse the amount of drug dissolved with HPLC (High-Performance Liquid Chromatography)

Biorelevant Solubility Filters

Biorelevant Solubility Filters require only a minimal amount of drug candidate (<1 mg). The built-in depth filter removes larger particles before fine (membrane) filtration, ensuring reproducible results. Each box of Biorelevant Solubility Filters (UNIP-MN) contains 50 filter housings (with slit septum caps) and 50 vials.
