Transport of drugs passive

During CAVH/CVVH, drug removal primarily occurs via con-vection/ultraflltration (the passive transport of drug molecules at the concentration at which they exist in plasma water into the ultrafiltrate). The clearance of a drug by either of these methods is thus a function of the membrane permeability for the drug, which is called the sieving coefficient (SC) and the rate of ultrafiltrate formation (UFR). The SC can be calculated as ...
