WebRenal clearance is defined as the volume of plasma totally cleared of a drug per unit time (eg,1 min) during passage through the kidneys. The renal clearance of drugs depends primarily on renal blood flow but also is impacted by urine pH, extent of plasma-protein binding, urine concentrating ability, and concomitant use of certain drugs.
