Summary
Despite the large surface area available for drug absorption through oral route, physiological, biological barriers and poor biopharmaceutical properties of therapeutic agents reduce the bioavailability for orally administered drugs. Ion pairing approach was used to improve drug permeation via passive transcellualr absorption and never used to target active carrier transporters. The current study demonstrates that ion pairing could improve drug uptake via transporter proteins.
