title: Effect of pirmenol on premature atrial complexes.
abstract: Suppression of premature atrial complexes by pirmenol, a new Class I antiarrhythmic agent, was examined following oral and intravenous routes of administration. In 4 patients, single intravenous doses of 50 to 150 mg reduced premature atrial beats greater than or equal to 90% for 2 to 4 h. Oral doses of 75 to 200 mg twice daily induced a mean arrhythmia reduction of greater than or equal to 80% in 5 out of 9 patients during a 24-h electrocardiographic recording compared with a baseline period of 48 h. No significant side-effects occurred. The results indicate that pirmenol effectively suppresses premature atrial complexes, which may be of value in the prevention of supraventricular tachyarrhythmias.
