Abstract
Liver disease in man is associated with a variety of pathophysiological processes which may influence the disposition of drugs in several ways. Interpretation of the observed pharmacokinetic changes in liver disease requires an understanding of the relationship between systemic drug clearance (Cls), volume of distribution (Vd) and the elimination half-life [t1/2(beta)], i.e. t1/2(beta) = 0.693 . Vd/Cls. Half-life will be a measure of the fluctuation in drug level one may expect with continued administration of a drug while clearance will determine the dose required to achieve a particular steady state level. Liver disease may affect clearance and volume of distribution and so produce changes..
