The pharmacotherapy of cirrhosis: concerns and proposed investigations and solutions.

WHAT IS KNOWN AND OBJECTIVE: The presence of cirrhosis has a multifaceted impact on hepatic drug metabolism. An area of concern and uncertainty in the care of patients with cirrhosis is the safe use of both prescription and over-the-counter medications.

COMMENT: Retrospective studies indicate a high incidence of adverse drug reactions (ADRs) among patients with cirrhosis related to use of certain medication classes including angiotensin-converting enzyme inhibitors, angiotensin receptor blockers and non-steroidal anti-inflammatory drugs. Conversely, use of appropriate medications, such as statins, may be decreased in this population due to fear of precipitating hepatotoxicity.

WHAT IS NEW AND CONCLUSION: Pharmacotherapy in cirrhosis is an area of uncertainty and heterogeneity in clinical practice. Prescribing and dosing guidelines are needed to decrease the risk of serious ADRs in this high-risk patient population.
