allapinin and Hypertension

Antiarrhythmic activity of oral allapinin was studied in 64 patients with ischemic heart disease. 27 of the patients had undergone coronary artery bypass grafting 2 to 12 months before, 19 patients had postinfarction cardiosclerosis, 38--arterial hypertension, 30--circulation insufficiency stage I. Arrhythmia presented as ventricular extrasystole (n = 28), paroxysmal atrial fibrillation (n = 18), paroxysmal atrial tachycardia (n = 11), frequent supraventricular extrasystole (n = 7). Arrhythmia continued from 6 months to 8 years. An effective single dose was defined with acute pharmacological test. The treatment course lasted for 21 days. Allapinin proved to be highly effective: ventricular ectopic activity was suppressed in 71.4% patients, atrial tachycardia paroxysms were prevented in 72.7%, paroxysms of atrial fibrillation--in 77.8%. Allapinin tolerance was good. Extracardiac side effects occurred most frequently, but dose lowering was necessary only in 6.2%. The drug was discontinued because of cardiac side effects in 4.7% cases. ECG monitoring is a highly informative method of the treatment efficacy control.
