[Clinical evaluation of amiodarone hydrochloride as an anti-arrhythmia agent].

15 patients with ventricular and supraventricular arrhythmias treated with Amiodarone hydrochloride via oral were studied. The results obtained show that in 86'6% of the cases the arrhythmia disappeared immediately, in 6'6% the arrhythmia disappeared late and in only one case the arrhythmia persisted. Statistical significance was found in the reduction of cardiac frequency as well as in the corrected QT interval for the frequency. The latter is an indirect consequence of the mode of action of the drug. The only side effect observed was the appearance of corneal opacification. It was demonstrated that this side effect is negligible when low doses which are equally effective are administered. The conclusion that Amiodarone is an excellent oral antiarrhythmic drug is reached. A daily dose of 400 mg during the first 20 days of each month with a rest of 10 days is recommended. In this way, the corneal opacification is minimal or nil. The possibility that the association of the drug with Quinidine could be effective in maintaining sinus rhythm post D.C. is suggested.
