WebHepatic disease differentially impacts flow- and capacity-limited drugs. Hepatic clearance of flow-limited drugs will markedly decrease with changes in hepatic flow such as might occur with portosystemic shunting. When administered orally, such drugs are normally characterized by a high first-pass metabolism and reduced oral bioavailability.
