Predicting drug absorption is crucial for successful drug development. This review explores chromatographic systems, especially amphiphilic ones, as alternative methods for estimating drug transport properties and bioavailability.

Area of Science:

  • Pharmacology
  • Biopharmaceutical Sciences
  • Analytical Chemistry

Background:

  • Drug discovery programs often overlook biopharmaceutical properties like drug absorption, leading to high failure rates in clinical development.
  • Poor biopharmaceutical characteristics are a primary cause of candidate attrition during clinical trials.
  • The high cost of drug development necessitates predictive methods for selecting bioavailable drug candidates early in the discovery process.

Purpose of the Study:

  • To review recent advancements in chromatographic systems for estimating drug transport properties.
  • To critically evaluate separation methods for predicting passive drug permeability across the gastrointestinal tract and skin.
  • To highlight the significance of amphiphilic chromatographic systems in assessing drug bioavailability.
