What is the Origin of Drug Transporters?

This concept is foundational to pharmacology and pharmacokinetics, emerging from the discovery of active transport mechanisms beyond simple passive diffusion. The identification of major transporter families, such as the ABC and SLC superfamilies, revolutionized the understanding of drug disposition. These proteins represent a major source of variability in patient response to medication.

What is the Mechanism of Drug Transporters?

Transporters operate by binding to a substrate molecule and utilizing energy, often in the form of ATP hydrolysis or electrochemical gradients, to physically translocate the molecule across the lipid bilayer. Efflux transporters, like P-glycoprotein, actively pump drugs out of cells, limiting intracellular concentration and therapeutic effect. Conversely, uptake transporters facilitate the entry of hormones or drugs into target tissues or excretory organs.

Drug Transporters

Meaning

Specialized membrane-bound proteins located on cell surfaces, including those in the liver, kidney, intestine, and blood-brain barrier, that actively move pharmaceutical agents and endogenous compounds across biological membranes. These proteins play a crucial role in the absorption, distribution, metabolism, and excretion (ADME) of therapeutic agents. They can either facilitate uptake into cells or promote efflux out of cells.
