アプリケーション

N-Acetylprocainamide hydrochloride may be used:
  • as an internal standard for spiking plasma samples for ultra-high-pressure liquid chromatography coupled with a diode array detector (UHPLC-DAD) analysis
  • to test its relaxant effect on tracheal smooth muscle tissue preparations
  • in preparation of complexes with N-acetyl-L-tyrosine methyl ester and N-acetyl-L-phenylalanine methyl ester for studying intermolecular interactions using nuclear magnetic resonance (NMR) spectroscopy studies

N-Acetylprocainamide hydrochloride is a class III antiarrhythmic compound. N-Acetylprocainamide hydrochloride has been used in a study to determine the disposition of procainamide and N-acetylprocainamide in protein-calorie malnutrition. N-Acetylprocainamide hydrochloride has also been used to study pharmacokinetics of procainamide and N-acetylprocainamide in rats.

生物化学的/生理学的作用

N-acetyltransferase II in liver catalyzes the conversion of procainamide to N-acetylprocainamide (NAPA).
Class III antiarrhythmic. Increases the duration of the action potential by decreasing the delayed outward potassium current, slightly decreasing the calcium current, and slightly depressing the inward rectifier potassium current. This is the active metabolite of procainamide that does not induce systemic lupus erythematosus.

The pharmacokinetics of distribution and elimination of procainamide and its major metabolite, N-actylprocainamide, were studied in rats. Eight rats were selected randomly, and each received intravenously 14C-labeled procainamide hydrochloride (75 mg/kg) or 14C-labeled N-acetylprocainamide hydrochloride (86 mg/kg) according to a

The influence of dietary protein deficiency on the disposition of procainamide (PA) and its major metabolite, N-acetylprocainamide (NAPA) was investigated in male Sprague-Dawley rats fed for 4 weeks on a 23 (control) or a 5% (low) protein diet ad libitum.

Ten healthy adults participated in a randomized, crossover drug interaction study testing procainamide only, procainamide plus levofloxacin, and procainamide plus ciprofloxacin. During levofloxacin therapy, most procainamide and N-acetylprocainamide (NAPA) pharmacokinetic parameters, including decreased renal clearances and renal clearance/creatinine clearance ratios
