The ultimate objective of conducting toxicity studies is to be able to effectively treat patients with relative safety. Traditionally, safety margins have been considered to be the ratio between the no observed toxic effect dose levels in animal and the therapeutic dose level. The underlying “believes” of this practice are that toxic effects or absence of them can be extrapolated from animal to man and that effects are related to doses. More recently, the latter has been refined to the hypothesis that effects are related to total exposure to the compound and that exposure is better determined by plasma concentrations than by dose (Collins et al 1990).
