Safety and efficacy of amiodarone. The low-dose perspective

Amiodarone has been reported to be a remarkably safe and effective drug in the European and South American experience but American investigators have published conflicting data. Since this disparity may be explained by a different dosing schedule, we prospectively evaluated the safety and efficacy of a low dose regimen in a group of 68 patients with cardiac arrhythmia resistant to conventional therapy, of whom 57 had manifested either ventricular tachycardia or fibrillation. All were loaded either intravenously (17) or orally, and maintained on an oral dose of 200 to 600 mg/day (mean daily dose 317 +/- 114 mg) and followed for 4 to 58 months (22 +/- 11). Results indicated that amiodarone was a safe and effective antiarrhythmic drug when used in lower doses.     

Acute amiodarone poisoning. Clinical and pharmacokinetic study

A 73 years old patient, treated with Amiodarone for ventricular tachycardia, ingested 6 000 mg of Amiodarone. This did not induce hemodynamic troubles or aggravation of ventricular arrhythmia. Treatment included a gastric lavage and purging at the third hour. Plasma assay revealed a concentration of 3.69 mg/l at the fourth hour. Their evolution can be described as the sum of two exponentials. The half-life of the first exponential is 4.9 hours ; the half-life of the second one is 544 hours. Amiodarone is an antiarrhythmic agent of high safety.

Malignant ventricular arrhythmia in the Wolff-Parkinson-White syndrome during amiodarone treatment

The ventricular rate during rapid atrial rhythms is related in Wolff-Parkinson-White (WPW) syndrome to antegrade effective refractory period of the accessory pathways. Among the many antiarrhythmic drugs available, amiodarone is most commonly used for its large therapeutic window and very long half-life. We report a case of cardiac pre-excitation syndrome in a young male patient in whom amiodarone therapy (3000 mg/weekly) was instituted to modify the dangerous ventricular response during atrial fibrillation (shortest R-R interval 190 ms, ventricular rate 210 beats/min). Four months later, starting pharmacological treatment, a new electrophysiological study documented a malignant ventricular arrhythmia: during atrial fibrillation the minimum R-R interval was 160 ms and the ventricular rate 280 beats/min. Finally, the possible mechanism of paradoxical effect observed in our patient is hypothesized. Amiodarone could favor conduction over the accessory pathways by slowing or blocking conduction into the atrioventricular node and decreasing concealed retrograde conduction into the accessory bypass tract by normally conducted beats.

Mechanisms of termination of supraventricular tachycardias by intravenous class III antiarrhythmic agents. A comparison of amiodarone and sotalol

The effects of amiodarone and sotalol were studied with programmed electrical stimulation of the heart in 19 patients with inducible tachycardia (AV nodal tachycardia: 10 cases, circus movement tachycardia: 9 cases). Amiodarone was administered intravenously at a dose of 300 mg over 2 min and sotalol at a dose of 1.5 mg kg-1 over 10 min. Both i.v. amiodarone and sotalol lengthened the transnodal conduction time, the effective refractory period of the AV node and the AV nodal Wenckebach cycle length. Only sotalol significantly lengthened the effective refractory periods of the right atrium and the right ventricle. Infused intravenously during tachycardia, amiodarone interrupted arrhythmia in five of six patients and sotalol in seven of ten cases. Tachycardia was stopped by blockade of the impulse into the AV node in three amiodarone patients and in five sotalol patients. In the remaining four cases, the weak link of the circuit was the accessory pathway. Thus i.v. sotalol exhibits electrophysiologic effects consistent with both class II and III activity, whereas the effects of i.v. amiodarone are the result of different activities throughout all areas of the cardiac tissue.     

Thyrotoxic heart disease. Part II--aspects of treatment of thyrotoxicosis with cardiac involvement

In the treatment of the thyrotoxic heart a radical, early thyroeliminating procedure should have preference. As the method of first choice a single administration of a whole calculated dose of I131 is recommended without previous medicamentous preparation up to 25-30 mCie which can be administered also in the out-patient department, with subsequent immediate treatment with thyrostatics and beta-blockers till remission of thyrotoxicosis is achieved (6-12 weeks). Total strumectomy after medicamentous preparation in remission of thyrotoxicosis is preferred in large multinodular, iodinated patients and in solitary toxic adenoma where however also partial STE (lobectomy) is possible and radioiodine is equivalent. Its dosage in toxic adenoma and nodular goitre is however in general higher than in diffuse goitre but the incidence of late postadministration hypothyroidism is lower. Fibrillation arrhythmia usually (in ca 60%) recedes spontaneously with the assistance of beta-blockers in remission of thyrotoxicosis. If this does not occur, pharmacological or electric cardioversion is necessary after anticoagulation preparation, because persistence of FA is an important risk factor of cardiac failure and thromboembolic complications. Eurhythmia then usually lasts as long as remission of thyrotoxicosis persists or there is no overdosage of substitution doses of T4 during treatment of hypothyroidism which develops after thyroelimination treatment. Amiodarone is unsuitable, even contraindicated, for treatment of fibrillation arrhythmia in thyrotoxic heart.
