WebIn these cases, clearance is almost synonymous with renal clearance or renal plasma clearance. Each substance has a specific clearance that depends on how the substance is handled by the nephron. Clearance is a function of 1) glomerular filtration , 2) secretion from the peritubular capillaries to the nephron , and 3) reabsorption from the ... WebRenal clearance mainly reflects the excretion of drug into the urine by the kidneys. Renal excretion of the drug is the neat result of glomerular filtration, active tubular secretion and tubular reabsorption. Rare drugs may undergo renal metabolism (e.g. insulin).
