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). The value of renal clearance is often used to identify the main mechanism ...
