[Captopril-induced liver dysfunction]

Captopril is widely used for congestive heart failure and arterial hypertension. Its main side effects are cough, neutropenia, and renal injury. Liver dysfunction has rarely been described. We present a 71-year-old man with an acute myocardial infarction who developed high fever and progressive disturbance of liver function tests, hepatocellular and cholestatic, after beginning captopril. When other, more likely causes for his condition were ruled out, captopril was discontinued and the fever and liver dysfunction then quickly resolved. We recommend periodic laboratory follow-up in patients treated with angiotensin-converting enzyme inhibitors.
