A 3-stage, concentration-maintaining intravenous infusion regimen of pirmenol, a new antiarrhythmic agent, was tested for efficacy and safety in 8 subjects with chronic, stable premature ventricular beats. The regimen, which consisted of (1) a priming bolus of 50 mg over 2 minutes, followed by (2) a rapid loading infusion of 2.5 mg/min for 1 hour, and (3) a maintenance infusion of 0.25 mg/min, rapidly achieved and maintained stable plasma pirmenol levels from 0.94 to 2.75 micrograms/ml, during infusions lasting up to 48 hours. Therapeutic efficacy was evaluated during 4-hour infusions in 5 patients utilizing a randomized, double-blind, placebo-controlled study design. Pirmenol suppressed average premature ventricular beat frequency 93 +/- 6% compared with control values (p = 0.03). Pirmenol infusions were unassociated with toxicity. There were slight but significant increases in diastolic blood pressure, QRS duration, and corrected Q-T interval. No significant changes occurred in systolic blood pressure, heart rate, P-R interval, or laboratory variables. Pirmenol is a promising therapeutic agent that warrants further evaluation. The 3-stage infusion satisfactorily achieves and maintains therapeutic plasma pirmenol levels.
