Amiodarone is a class III antiarrhythmic drug widely used for treating a number of cardiac arrhythmias such as atrial fibrillation, both in young and elderly people. Its hepatotoxicity is usually mild and occurs with delayed onset. Acute hepatotoxicity is a rare side effect; it is sometimes related to intravenous administration. In that case, acute hepatocellular injury occurs within 24 hours following amiodarone's intravenous administration. Liver enzymes significantly improve after stopping treatment. Its acute toxicity due to intravenous administration is believed to depend on different mechanisms, such as ischemic liver injury, mithochondrial damage, hypersensitivity reactions. It is sometimes due to the vehicle (polysorbate-80). The present case report describes an unusual condition of acute elevation of serum aminotransaminase concentrations following intravenous amiodarone's administration. An 88-year-old woman, affected with acute heart failure, developed acute hepatitis after starting intravenous amiodarone for atrial fibrillation with rapid ventricular response. Liver transaminases returned to baseline values within 15 days after discontinuing the drug. The authors hypothesized that this kind of injury might be due to liver ischemia, with possible superimposed direct drug toxicity and worsened by polysorbate 80, the solubilizer of amiodarone infusion. It can also be linked to high dose in an aged person. The CIOMS/ RUCAM Scale identified our patient's acute hepatitis as a highly probable adverse drug reaction.

Abstract
Amiodarone is a class III antiarrhythmic drug widely used for treating a number of cardiac arrhythmias such as atrial fibrillation, both in young and elderly people. Its hepatotoxicity is usually mild and occurs with delayed onset. Acute hepatotoxicity is a rare side effect; it is sometimes related to intravenous administration. In that case, acute hepatocellular injury occurs within 24 hours following amiodarone's intravenous administration. Liver enzymes significantly improve after stopping treatment. Its acute toxicity due to intravenous administration is believed to depend on different mechanisms, such as ischemic liver injury, mithochondrial damage, hypersensitivity reactions. It is sometimes due to the vehicle (polysorbate-80). The present case report describes an unusual condition of acute elevation of serum aminotransaminase concentrations following intravenous amiodarone's administration. An 88-year-old woman, affected with acute heart failure, developed acute hepatitis after starting intravenous amiodarone for atrial fibrillation with rapid ventricular response. Liver transaminases returned to baseline values within 15 days after discontinuing the drug. The authors hypothesized that this kind of injury might be due to liver ischemia, with possible superimposed direct drug toxicity and worsened by polysorbate 80, the solubilizer of amiodarone infusion. It can also be linked to high dose in an aged person. The CIOMS/ RUCAM Scale identified our patient's acute hepatitis as a highly probable adverse drug reaction.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
