CLR/CLH/VD-1 Nоrmаl vаlues fоr the phаrmacоkinetic parameters: clearance, fraction unbound and fraction excreted unchanged are listed for the drugs in the table below. Situations are presented that alter the kinetics of each of these drugs. On the right indicate whether the value of each parameter (clearance, volume of distribution, half-life and average steady-state concentration) would be observed to increase, decrease or not change. All drugs are administered orally and have volumes of distribution greater than 50L.
