A validated liquid chromatography-atmospheric pressure chemical ionization-tandem mass spectrometry method for quantitation of cocaine and benzoylecgonine in human plasma.
In order to support studies on various medication protocols for the treatment of cocaine abuse, an accurate, precise, and sensitive (2.5 to 750 ng/mL) liquid chromatography-tandem mass spectrometry assay was developed to determine cocaine and benzoylecgonine in human plasma. Cocaine-d3 and benzoylecgonine-d3 were added as internal standards and samples were subjected to solid-phase extraction. ...
متن کاملDevelopment and Application of a Validated Liquid Chromatography-Mass Spectrometry Method for the Determination of Dexchlorpheniramine Maleate in Human Plasma
A convenient liquid chromatographic-single Quadrupole mass spectrometric (LC-MS) method was developed and validated for dexchlorpheniramine maleate (INN name: chlorphenamine) determination in human plasma. The need for just a single liquid-liquid extraction with ethyl acetate and being highly sensitive were the advantages of this method. The linearity was also excellent over the range of 1...
متن کاملLiquid chromatography–tandem mass spectrometry (LC-MS) method for the assignment of enalapril and enalaprilat in human plasma
A rapid and sensitive liquid chromatography–tandem mass spectrometry (LC-MS) method was developed for the determination of enalapril and enalaprilat in human plasma. Detection of analytes was achieved by tandem mass spectrometry with electrospray ionization (ESI) interface in positive ion mode which was operated under the multiple-reaction monitoring mode. Sample pretreatment was involved...
متن کاملA Validated Liquid Chromatography-Tandem Mass Spectrometry Coupled with Liquid-Liquid Extraction for Indacaterol Quantitation in Human Plasma
Indacaterol is a recent ultra-long-acting inhaled β2-agonist bronchodilator. The current work validated an in-house developed high performance liquid chromatography (HPLC)-tandem mass spectrometry (MS/MS) bioassay for indacaterol in human plasma. Ethyl acetate was used in a liquid-liquid extraction (LLE) method to extract indacaterol from plasma samples. A 200 μL of the mobile phase (water-meth...
متن کاملDetermination of Mebudipine in Human Plasma by Liquid Chromatography–tandem Mass Spectrometry
In previous studies, mebudipine, a dihydropyridine calcium channel blocker, showed a considerable potential to be used in cardiovascular diseases. The aim of the current study was to develop a valid method using reversed-phase high performance liquid chromatography coupled with electrospray ionization mass spectrometry to assay mebudipine in the human plasma. Separation was achieved on a Zorbax...
