WebClearance (Cl) = Elimination rate / Plasma drug concentration (6.9) Renal Clearance (ClR): It can be defined as the volume of blood or plasma which is completely cleared of the unchanged drug by the kidney per unit time. It is expressed mathematically as: ClR = Rate of urinary excretion / Plasma drug concentration (6.10) WebMurine studies also found that the kidneys appear to have a role in clearance because adiponectin final degradation products were noted in urine. Chronic kidney disease (CKD) patients have increased adiponectin levels vs their healthy counterparts.
