Modified colorimetric method for procainamide in plasma.
نویسندگان
چکیده
We describe a modified colorimetric method for determining procainamide in plasma by use of a diazotization and coupling reaction with N-(1-naphthyl)-ethylenediamine dihydrochloride (Marshall's reagent). The sensitivity of the assay is increased twofold over the originally reported colorimetric method, and the lower limit of detection for the assay of a 1.0-ml plasma sample has been decreased to 0.5 mg/liter.

Influence of midazolam on pharmacokinetic parameters of procainamide in rabbits.
The majority of antiarrhythmic drugs have very narrow therapeutic range, and they may cause some side effects at doses used for curing cardiac arrhythmias. These drugs may enter different interactions. Procainamide also may interact with other drugs. Also some other drugs may change pharmacokinetics of procainamide, for example the iv anesthetics influence on pharmacokinetic parameters of proca...
متن کاملThe effect of procainamide on plasma cholinesterase activity.
The in vitro effect of procainamide on plasma cholinesterase (PCHE) activity in the plasma of ten normal ASA physical status I patients was studied using a kinetic method. The mean plasma cholinesterase activity without procainamide (control) was 0.90 +/- 0.09 units.ml-1. The dibucaine numbers of all the samples were in the normal range of 78 to 86, indicating normal genotypes. The mean plasma ...
متن کاملA modified low-cost colorimetric method for paracetamol (acetaminophen) measurement in plasma.
BACKGROUND Despite a significant increase in the number of patients with paracetamol poisoning in the developing world, plasma paracetamol assays are not widely available. The purpose of this study was to assess a low-cost modified colorimetric paracetamol assay that has the potential to be performed in small laboratories with restricted resources. METHODS The paracetamol assay used in this s...
متن کاملPharmacodynamics of intravenous procainamide as used during acute electropharmacologic testing.
No previous studies have determined the pharmaco-dynamics of intravenous procainamide when administered in a dose of 15 mg/kg and at a rate of 50 mg/min, as is common practice during electropharmacologic testing. In this study, 30 patients received procainamide in this fashion; the right ventricular effective refractory period and the QRS duration at a ventricular pacing rate of 120/minute were...
متن کاملDetermination of plasma procainamide and N-acetylprocainamide concentration by high-pressure liquid chromatography.
We describe a routine method for determining concentrations of the antiarrhythmic drug procainamide and its active metabolite, N-acetylprocainamide, in plasma. A simple extraction of 1.0 ml of plasma is followed by separation and chromatographic analysis by use of a column containing microparticulate silica. p-nitro-N-(2-diethylaminoethyl)benzamide hydrochloride was synthesized and used as the ...
