The processes of absorption, distribution and elimination are vitally important in all drug therapy, for collectively they determine the drug concentrations present at the sites of toxic and therapeutic effects. Pharmacokinetic considerations are especially critical for drugs with low therapeutic ratios, e.g. antineoplastic agents. The pharmacokinetics of nitroimidazole radiosensitizers have been reviewed recently (1). Considerable evidence now shows that all aspects of the pharmacokinetics of nitroimidazoles (as for other drugs) are strongly influenced by lipophilicity. The aim in this paper is to discuss the pharmacokinetics of nitroimidazole drugs with particular emphasis on this important property.
