The Cockcroft-Gault (C-G) formula uses a patient’s weight (kg) and gender to predict CrCl (mg/dL). The resulting CrCl is multiplied by 0.85 if the patient is female to correct for the lower CrCl in females. The C-G formula is dependent on age as its main predictor for CrCl.

WebIntroduction. Renal clearance is most commonly a feature of polar, low LogD7.4 (<~1) compounds due to their low plasma protein binding, lack of passive permeability (and inability to facilitate re-absorption in the distal tubule), and the high expression in the kidney of a number of transporter proteins (e.g. OATs and OCTs).

WebThe term clearance describes the process of drug elimination from the body or from a single organ without identifying the individual processes involved.
