Although it is a frequently used antiarrhythmic agent, the routes and mechanisms of procainamide excretion and the effect of urine pH, urine flow rate, and disease states on its renal clearance, plasma half-time, and 6-hr renal excretion have not been defined. Procainamide was administered intravenously to 20 mongrel dogs and 15 humans in a 500-mg bolus or by constant infusion. The 6-hr excretion averaged 65% in normal humans and dogs. Patients with primary renal disease and renal impairment secondary to cardiac failure or hepatic disease had prolonged T½ (5.85 ± 0.39 hr) and decreased renal excretion (40.8 ± 1.8%) compared
