The pharmacokinetics of procainamide (PA) and N-acetylprocainamide (NAPA) were compared in 3 normal subjects after simultaneous intraveous injection of PA and NAPA-13C. The distribution kinetics of both compounds were modeled with a 3-compartment mamillary system, and it was found that their steady-state distribution volumes were not significantly different, averaging 1.41 L/kg for PA and 1.46 L/kg for NAPA. However, the intercompartmental clearances of NAPA were slower than those of PA. In these normal subjects, the average elimination t1/2 and total elimination clearance for PA were 2.5 hr and 589.8 ml/min, and for NAPA were 6.2 hr and 233.7 ml/min. Mean renal clearances of PA (346.7 ml/min) and of NAPA (199.5 ml/min) exceeded the usual rate of glomerular filtration, which suggests that both compounds are eliminated in part by renal tubular secretion. All subjects were phenotypic rapid acetylators of isoniazid and converted approximately one fourth of the administered PA dose to NAPA-12C. The fate of 15.4% of the administered PA and 14.5% of the administered NAPA-13C was not determined.
