WebRenal clearance (CL R) is the net result of glomerular filtration of unbound drug plus tubular secretion minus tubular reabsorption. An acute or chronic reduction in GFR results in a decrease in CL R . WebThe term clearance describes the process of drug elimination from the body or from a single organ without identifying the individual processes involved. Clearance may be defined as the volume of fluid cleared of drug from the body per unit of time. The units for clearance are milliliters per minute (mL/min) or liters per hour (L/h).
