Fifty Years of Unraveling the Clinical Pharmacology of Corticosteroids
2024, Journal of Pharmaceutical SciencesHandling of highly coeluted chromatographic peaks by multivariate curve resolution for a complex bioanalytical problem: Quantitation of selected corticosteroids and mycophenolic acid in human plasma
2018, TalantaCitation Excerpt :So, developing a fast, easy and reliable analytical methodology while keeping the sensitivity and reproducibility at a reasonable level for simultaneous quantitation of medications is highly valuable. There are a variety of chromatographic methodologies in the literature for individually or simultaneously quantification of corticosteroids in plasma or serum samples such as high performance liquid chromatography (HPLC) with UV detection [5–7], fluorescence detection [8] or diode array detection coupled with second-order calibration [9], gas chromatography–mass spectrometry (GC–MS) after purification by immunoaffinity chromatography [10] and liquid chromatography–mass spectrometry or tandem mass spectrometry (LC-MS/MS) [11–14]. A liquid chromatography-full scan high resolution accurate mass spectrometry (LC-HRMS) method for quantifying prednisone and prednisolone in human plasma using a quadrupole time-of-flight mass spectrometer (Q-TOF) was developed [15].
Validated assay for the simultaneous determination of cortisol and budesonide in human plasma using ultra high performance liquid chromatography-tandem mass spectrometry
2014, Journal of Pharmaceutical and Biomedical AnalysisCitation Excerpt :Charcoal stripped human plasma was used as the validation matrix to avoid any potential interference from the endogenous CORT content of the neat blank human plasma. Charcoal stripped human plasma has been previously used as the blank matrix to quantitate CORT, and other corticosteroids, in human plasma, using HPLC/UV [25], and LC/MS/MS techniques [9,26], and these methods were validated [25] according to FDA guidelines [9,26]. The results for accuracy and precision are presented in Table 1.
Carrier mediated transport solvent bar microextraction for preconcentration and determination of dexamethasone sodium phosphate in biological fluids and bovine milk samples using response surface methodology
2013, Journal of Chromatography B: Analytical Technologies in the Biomedical and Life SciencesCitation Excerpt :The most commonly used chromatographic technique for dexamethasone is liquid chromatography with UV or MS detection [13,15–27]. Most of these methods are suitable for serum or urine [10,11,14–20], and only some for edible tissues [12,13,21–25]. Among these there are only few methods optimized for the analysis of milk [12,18,26,27].
