WebbA highly protein bound drug may be competitively displaced by another highly bound drug and the pharmacologic effect of the displaced drug (free, unbound) will increase and the renal clearance will increase. In disease states characterized by hypoalbuminemia, the concentration of free drug will be higher at any total concentration. WebbThe decline from peak plasma concentrations after drug administration results from drug elimination or removal by the body. The elimination of most drugs from the body involves the processes of both metabolism (biotransformation) and renal excretion (see Chapter 6). For many drugs, the principal site of metabolism is the liver.
