WebHepatic drug transporters are present throughout parenchymal liver cells and affect a drug’s liver disposition, metabolism, and elimination (for review, see [ 1, 2 ]). The 2 primary types of transporters are influx, which translocate molecules into the liver, and efflux, which mediate excretion of drugs into the blood or bile. WebAug 22, 2024 · Biotransformation is a metabolic process that takes place mainly in the liver and helps to facilitate the excretion of both exogenous and endogenous substances. A series of reactions alter the chemical structures of these substances. The enzymes that catalyze these reactions can cause the substrate to become inactive, active, and even toxic. WebDrug biotransformation occurs in quantitatively important amounts in the liver, gastrointestinal tract, kidneys, lung, and skin. However, nearly all organs have some metabolic activity.
