title: Effectiveness of pirmenol hydrochloride in suppressing high frequency ventricular ectopy: a placebo-controlled, double-blind, multicenter study.
abstract: An 8-center European clinical trial has established that pirmenol in dosages up to 400 mg daily is effective and safe for treating stable, high frequency, ventricular ectopy. At dosages of 300 mg and 400 mg of pirmenol a day, the average frequency of ectopy/hour decreased markedly compared with baseline values. The percentage of responders (premature ventricular contraction suppression of 70% compared with baseline) among the patients receiving 300 mg or 400 mg of pirmenol/day was significantly higher than in the placebo group. Observation of the frequency of reported adverse experiences, clinical laboratory tests and electrocardiographic tracings shows that dosages of pirmenol up to 400 mg daily were well tolerated.
