title: Intravenous N-acetylprocainamide disposition kinetics in coronary artery disease.
abstract: N-Acetylprocainamide (NAPA) disposition kinetics was studied in eight patients with coronary artery disease. NAPA was given over a 45-min period by intravenous infusion, and blood samples were drawn at specified times for 24 hr. NAPA plasma levels were determined by a specific high-pressure liquid chromatography (HPLC) procedure and the concentration-time data were fit to a three-compartment model. Mean (+/- SD) values for the elimination half-life, the total body clearance, and the steady-state volume of distribution were 9.53 +/- 3.22 hr, 1.98 +/- 0.40 ml/min/kg, and 1.30 +/- 0.18 1/kg. There was moderate intersubject variability in disposition. The data reported here differ from those reported for normal subjects.
