Core Tip

Core tip: The widespread use of polypharmacotherapy makes drug-drug interactions due to inhibition or induction of drug-metabolizing enzymes virtually unavoidable, with consequently high risk of serious or even life-threatening adverse effects. An appropriate management of such interactions by dose adjustment is made difficult by their high interindividual variability. This review, which focuses on the variability associated with liver functional status, presents an updated discussion of the relevant literature, analyzes the mechanisms responsible for the effect of liver dysfunction on the magnitude of these interactions, and outlines the criteria on which their clinical management should be based.
