In Vitro Permeability Assay Kits

Drug absorption is drugs' movement into the bloodstream. This process is influenced by many factors, including drugs formulation, physicochemical properties, and route of administration. Regardless of the route of administration, the drug must first be dissolved and absorbed before it can exert a therapeutic effect. By intervening in factors that affect drug absorption, its pharmacokinetic (PK) characteristics can be changed.

Drugs' permeability across biological membranes, epithelial cells, or endothelial cells is a critical factor that influences the absorption and distribution. Drugs may cross cell membranes through passive diffusion, facilitated passive diffusion, active transport, and pinocytosis. The drug's physicochemical properties (such as lipophilicity and molecular size), and membrane-based efflux, can lead to poor permeability.
