On the pharmacokinetics of cephalosporin antibiotics.

A review is given on the pharmacokinetic characteristics of some cephalosporin antibiotics. The use of the pharmacokinetic parameters serum concentration, serum protein binding, serum half life, and apparent volume of distribution as a basis for the selection of the clinically most effective cephalosporin derivative is discussed. It is concluded that these parameters must be used in conjunction with data on tissue distribution to specialized sites, and with information on antibacterial activity and toxicity.
