Aprindine is a very effective antiarrhythmic agent with a narrow therapeutic ratio. We report a patient who suffered from granulomatous hepatitis probably due to the administration of aprindine. Evidence of hepatitis appeared within 6 weeks of initiating aprindine therapy and resolved rapidly when the drug was withdrawn. Six months later, fibrosis but no granulomata were found in the expanded portal tracts. Our observations suggest that granulomatous hepatitis can occur during aprindine therapy.
We present a case treated with aprindine and metoprolol combined with a DDD type pacemaker for repetitive monomorphic ventricular tachycardia. A 50-year-old man was admitted because of palpitation and near syncope attack. Electrocardiogram showed repetitive monomorphic ventricular tachycardias (RBBB LAD type) and R-R interval of about 440 msec and I degree A-V block in sinus rhythm. Electrophysiologic study disclosed that overdrive pacing in HRA suppressed ventricular tachycardias. Left ventriculography revealed a dilated left ventricular and decreased contractility. Antiarrhythmic agents such as quinidine sulfate, procainamide, disopyramide, mexiletine, lidocaine and propranolol were not effective. But, the combination of propranolol and aprindine decreased the rate of the ventricular tachycardia. With aprindine 60 mg/day and metoprolol 60 mg/day combined with the atrioventricular sequential pacing at 85/min, ventricular tachycardia completely disappeared.
