Introduction
Propafenone is an oral antiarrhythmic agent that has been in wide use for several decades. Long term propafenone therapy is associated with a low rate of serum aminotransferase elevations and therapy rarely can cause a self-limited, acute cholestatic liver injury.
Background
Propafenone (proe" pa fee' none) is an analogue of the local anesthetic procaine and has electrophysiological effects that resemble quinidine (antiarrhythmic Class IC). Propafenone appears to act by blocking open sodium channels and outward potassium channels. As a consequence, it decreases cardiac automaticity, increases refractory periods and slows conduction. Propafenone was approved for use in the United States in 1989, and current approved indications include prevention of recurrence of symptomatic atrial fibrillation after cardioversion in patients without structural heart disease, and for suppression of life threatening ventricular arrhythmias. Propafenone is available as tablets of 150, 225 and 300 mg and as extended release capsules of 225, 325 and 425 mg generically and under the brand name Rythmol. The usual maintenance dose in adults of standard release forms is 150 to 300 mg every 8 hours and 225 to 425 mg of the sustained release forms every 12 hours. The most common side effects include dizziness, palpitations, chest pain, dyspnea, fatigue, headache, anxiety, gastrointestinal upset, change in taste and blurred vision.
Hepatotoxicity
In clinical trials, propafenone was associated with a low rate of serum aminotransferase and alkaline phosphatase elevations. Since its approval and more widescale use, propafenone has been linked to rare instances of clinically apparent liver injury, at least a dozen cases of which have been reported in the literature. Patients usually present with symptoms of jaundice and pruritus 2 to 8 weeks after starting propafenone, and the pattern of serum enzyme elevations are typically mixed (Case 1) or cholestatic (Case 2). Immunoallergic and autoimmune features are uncommon. While the jaundice can be prolonged, patients typically recover in 1 to 3 months and there have been no instances of acute liver failure, chronic hepatitis or vanishing bile duct syndrome attributed to its use.
Likelihood score: B (rare but likely cause of clinically apparent liver injury).
Mechanism of Injury
The mechanism by which propafenone causes liver injury is unknown. Propafenone is extensively metabolized in the liver by the cytochrome P450 system, predominantly CYP 2D6 and is sensitive to drug-drug interactions and hypermetabolizer status.
Outcome and Management
The severity of hepatic injury due to propafenone ranges from mild and transient serum enzyme elevations to acute cholestatic hepatitis. Propafenone has not been linked to acute liver failure, chronic liver injury or vanishing bile duct syndrome. Recurrence upon reexposure is common and should be avoided. There is no evidence for cross sensitivity to the hepatic injury of propafenone with other antiarrhythmic agents.

CASE REPORTS
Case 1. Cholestatic hepatitis due to propafenone.(1)
A 73 year old woman developed itching two weeks after starting propafenone (450 mg daily) for atrial fibrillation. She denied jaundice, abdominal pain, rash and fever. She had no history of liver disease, alcohol abuse or risk factors for viral hepatitis. She had known atherosclerosis, coronary artery disease, cerebrovascular disease, transient ischemic attacks, chronic obstructive pulmonary disease, diabetes and dyslipidemia. Her medications taken chronically included aspirin (100 mg daily), isosorbide mononitrate (20 mg twice daily), NPH insulin (8 units daily), glibenclamide (5 mg three times daily) and metformin (850 mg daily). Laboratory testing showed elevations in serum enzymes, but normal bilirubin (Table). Tests for hepatitis A, B and C were negative and ultrasound of the liver showed no evidence for biliary obstruction. Once propafenone was stopped and replaced by verapamil (120 mg daily), serum enzymes fell into the normal range. When she redeveloped atrial fibrillation 6 months later, propafenone was restarted, but her serum enzymes rapidly became abnormal, and it was again stopped. Five weeks later she redeveloped itching and was again found to have elevations in serum enzymes. On questioning, she reported restarting propafenone on her own.

Comment
This patient developed a mixed pattern of serum enzyme elevations without jaundice on three occasions while taking propafenone. On each occasion, she was symptomatic with itching, suggesting a cholestatic liver injury. At least a dozen cases of cholestatic hepatitis have been reported associated with propafenone use. The latency to onset has ranged from 1 to 6 weeks and the pattern of enzyme elevation is usually cholestatic or mixed. Most patients have had mild jaundice and all cases have recovered with stopping the medication. As this case demonstrates, recurrence on reexposure is typical, the recurrences having a similar latency and severity. This phenomenon is different from cases of drug induced immunoallergic hepatitis that usually recur within days of reexposure with a more severe and abrupt onset and course.

Case 2. Cholestatic hepatitis due to propafenone.(2)
A 62 year old woman was found to have abnormal liver tests one month after starting propafenone (450 mg daily) for atrial fibrillation. At that point, she had no symptoms of liver disease and specifically denied abdominal pain, dark urine, rash and fever. She had no history of liver disease, alcohol abuse or risk factors for viral hepatitis. She had a history of breast cancer treated with mastectomy 30 years previously. She also had adult-onset diabetes for which she took insulin. The liver test abnormalities were thought to be due to malignancy and because the arrhythmias were not adequately controlled, propafenone was continued and the dose was increased to 600 mg daily. Over the next few weeks she developed nausea and liver tests worsened (Table). Tests for hepatitis A, B and C were negative as were autoantibodies. Ultrasound and computerized tomography of the abdomen showed no evidence of biliary obstruction, gall stones or malignancy. Propafenone was discontinued and she was treated with sotalol (150 mg daily). Over the next two months, liver tests returned to normal.

Comment
This patient developed a mild cholestatic hepatitis within a month of starting propafenone. The abnormal liver tests were initially attributed to possible malignancy, but after lack of evidence of cancer on imaging, propafenone was considered the likely cause and it was discontinued, whereupon symptoms rapidly improved and liver tests returned to normal within the next two months. Typical of propafenone is the latency to onset of 3-6 weeks, mild cholestatic hepatitis and prompt improvement on stopping.
