[PMID: 35550343 DOI: 10.1016/j.vaa.2021.08.049] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2020] [Revised: 07/01/2021] [Accepted: 08/07/2021] [Indexed: 01/25/2023]
Abstract
OBJECTIVE To investigate pharmacokinetics (PK) of fentanyl administered by target-controlled infusion (TCI), and to develop a PK model optimized by covariates for TCI in anaesthetized dogs. STUDY DESIGN Prospective clinical study. ANIMALS A group of 20 client-owned dogs with spinal pain undergoing anaesthesia for magnetic resonance imaging. METHODS Fentanyl was administered as an infusion to 20 anaesthetized dogs using a TCI system incorporating a previously described fentanyl two-compartment PK. Arterial blood samples were collected at specific time points during the infusion and over 60 minutes post-infusion for measurement of fentanyl plasma concentrations. The predictive performance of the Sano PK model was assessed by comparing predicted and measured plasma concentrations. A population PK analysis was then performed using a nonlinear mixed-effect modelling approach, allowing inter- and intra-individual variability estimation. Finally, a quantitative stepwise evaluation of the influence of various covariates such as weight, body condition score, size, size-related age, sex and type of premedication on the PK model was considered. RESULTS Overall predictive performance of the Sano PK set of variables was not clinically acceptable in anaesthetized dogs. Fentanyl PK was best described by a three-compartment model. Weight and sex were found to affect the volume of distribution of the central compartment. Addition of these two covariate/variable associations resulted in a reduction of the objective function value (OFV) from -340.18 to -448.34, and of the median population weighted residual and the median population absolute weighted residual from 16.1% and 38.6% to 3.9% and 20.3%, respectively. Fentanyl infusions at measured concentrations up to 5.4 ng mL-1 in sevoflurane-anaesthetized dogs resulted in stable anaesthesia and smooth recoveries without complications. CONCLUSIONS AND CLINICAL RELEVANCE A population three-compartment PK model for fentanyl TCI in anaesthetized dogs was developed. Weight and sex have been detected and incorporated as significant covariates.

Hydrophilic interaction liquid chromatography tandem mass spectrometry analysis of malonyl-coenzyme A in breast cancer cell cultures applying online solid-phase extraction.

Abstract
Cofactors such as coenzyme A and its derivatives acetyl-coenzyme A and malonyl-coenzyme A are involved in many metabolic pathways. Due to trace level concentrations in biological samples and the high reactivity of cofactors, a fast, sensitive, and selective method for quantification is mandatory. In this study, online solid-phase extraction was coupled successfully to hydrophilic interaction liquid chromatography with tandem mass spectrometry for isolation of analytes in complex matrix and quantification by external calibration. Online solid-phase extraction was carried out by application of a weak anion-exchange column, whereas hydrophilic interaction liquid chromatography separation was performed on an amide modified stationary phase. Sample preparation of the extracts before the analysis was reduced to a centrifugation and dilution step. Moreover, the applied online solid-phase extraction significantly reduced matrix effects and increased the signal-to-noise ratio. The limit of detection and the limit of quantification were in the lower nanomolar range. Finally, the applicability of this method was demonstrated on MCF-7 breast cancer cell cultures, a commonly used model system, where acetyl-coenzyme A and malonyl-coenzyme A were determined using standard addition procedure in concentrations of 1.98 μM and 41 nM, respectively.

Abstract
In this study, a selective and sensitive high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method requiring low sample volume (≤100 μL) was developed and validated for the quantitative determination of the opioid drug fentanyl in plasma and cerebrospinal fluid (CSF). A protein precipitation extraction with acetonitrile was used for plasma samples whereas CSF samples were injected directly on the HPLC column. Fentanyl and (13) C6 -fentanyl (Internal Standard) were analyzed in an electrospray ionization source in positive mode, with multiple reaction monitoring (MRM) of the transitions m/z 337.0/188.0 and m/z 337.0/105.0 for quantification and confirmation of fentanyl, and m/z 343.0/188.0 for (13) C6 -fentanyl. The respective lowest limits of quantification for plasma and CSF were 0.2 and 0.25 ng/mL. Intra- and inter-assay precision and accuracy did not exceed 15%, in accordance with bioanalytical validation guidelines. The described analytical method was proven to be robust and was successfully applied to the determination of fentanyl in plasma and CSF samples from a pharmacokinetic and pharmacodynamic study in newborn piglets receiving intravenous fentanyl (5 µg/kg bolus immediately followed by a 90-min infusion of 3 µg/kg/h).

Abstract
A fentanyl patch is widely used for the treatment of cancer pain. Its few adverse effects include constipation and drowsiness. The absorption volume of transdermally applied fentanyl may differ according to its site of application and variability in patch adhesion. Since fentanyl is predominantly metabolized by the drug-metabolizing enzyme cytochrome P450 (CYP) 3A4 in the liver, its concentration may vary in cases of physiologically reduced CYP3A4 activity in the liver (liver disease and aging) or on co-administration of drugs. The clinical significance of measuring plasma concentration of fentanyl is high, but conventional methods require complicated processes such as solid-phase extraction and liquid-liquid extraction before the sample is injected into an HPLC system. In this study, a simple liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed for determining plasma fentanyl concentrations by deproteinization with acetonitrile. A recovery test was conducted using an absolute calibration curve to confirm the method's linearity and inter- and intra-day reproducibility. The required plasma volume for detection was reduced from 1 mL in the conventional method to 20 µL in the present study, and a good calibration curve was obtained in the concentration range from 0.05 to 5 ng/mL. These findings suggest that the method for sample preparation and quantification developed in this study are appropriate for measuring fentanyl concentration in human plasma in clinical settings.

Abstract
A rapid LC-MS/MS assay method for simultaneous quantification of morphine, fentanyl, midazolam and their major metabolites: morphine-3-β-D-glucuronide (M3G), morphine-6-β-D-glucuronide (M6G), norfentanyl, 1'-hydroxymidazolam (1-OH-MDZ) and 4-hydroxymidazolam (4-OH-MDZ) in samples of human plasma has been developed and validated. Robotic on-line solid phase extraction (SPE) instrumentation was used to elute the eight analytes of interest from polymeric SPE cartridges to which had been added aliquots (150 μL) of human plasma and aliquots (150 μL) of a mixture of two internal standards, viz. morphine-d3 (200 ng/mL) and 1'-hydroxymidazolam-d5 (50 ng/mL) in 50 mM ammonium acetate buffer (pH 9.25). Cartridges were washed using 10% methanol in ammonium acetate buffer, pH 9.25 (1 mL, 2 mL/min) before elution with mobile phase comprising 0.1% formic acid in water (A) and acetonitrile (B) with a flow rate of 0.6 mL/min using an 11.5 min run time. The analytes were separated on a C18 X-Terra® analytical column. The linear concentration ranges were 0.5-100 ng/mL for fentanyl, norfentanyl and midazolam; 1-200 ng/mL for 4-hydroxymidazolam, 2.5-500 ng/mL for 1'-hydroxymidazolam and 3.5-700 ng/mL for morphine, M3G, and M6G. The method showed acceptable within-run and between-run precision (relative standard deviation (RSD) and accuracy <20%) for quality control (QC) samples spiked at concentrations of 80% and 50% of the ULOQ, 3 times higher than the LLOQ, and also at the LLOQ. Furthermore, analytes were stable in samples (after mixing with internal standard) for at least 48 h in the autosampler (except for 4-hydroxymidazolam which decreased by 22% after 24 h), 5 h at room temperature and after three cycles of freeze and thaw. No autosampler carry-over was observed and the absolute recovery (the area ratio of analyte in plasma relative to that in ammonium acetate buffer 50 mM, pH 9.25) was in the range 40% (midazolam) to 110% (morphine). The assay was applied successfully to the measurement of the analytes of interest in plasma samples from patients on extracorporeal membrane oxygenation (ECMO).

Abstract
A simple, rapid and validated high performance liquid chromatography method with UV detection for the quantification of an opioid agonist, fentanyl (FEN), in rat plasma was developed. The assay procedure involved chromatographic separation using a ZIC-HILIC SeQUANT column (250 mm × 4.6 mm, i.d., 5 μm) and a mobile phase of acetonitrile and acetate buffer (pH 3.4, 20mM) of ratio (=65:35, v/v) at a flow rate of 1.2 mL/min and detection wavelength of 201 nm. Plasma sample (100 μL) pretreatment was based on simple deprotienization by acetonitrile spiked with clonidine as an internal standard (I.S.) of 20 ng/mL followed by extraction with tert-butyl methyl ether and centrifugation. The organic layer was evaporated under N(2) gas and reconstituted with 100 μL of acetate buffer (pH 3.4, 20mM), and 50-μL portions of reconstituted sample were injected onto the column. Sample analysis including sample pretreatment was achieved within 35 min. Calibration curve was linear (r ≥ 0.998) from 5 to 100 ng/mL. Both intra- and inter-day assay precisions that are presented through RSD were lower than 12.6% for intra-day and lower than 12.0% for inter-day assessment. Limit of detection was 0.8 ng/mL at S/N of 3. This method was omitting the use of expensive solid phase extraction and time consuming liquid extraction procedures. Moreover, the present method was successfully applied to study pharmacokinetic parameters of FEN after intraperitoneal administration to male Wistar rat. Pharmacokinetic parameters estimated by using moment analysis were T(1/2) 198.3 ± 44.7 min, T(max) 28.3 ± 2.9 min and AUC(0-180) 15.6 ± 2.9(× 10(2))ngmin/mL.

Abstract
This paper describes the determination of a drug candidate and two metabolites in human plasma by column-switching LC-MS/MS after protein precipitation. Starting from a standard method with a quantitation limit of 0.5 ng/mL, a highly sensitive assay was developed, employing UHPLC separation and detection on an API 5000 mass spectrometer. The injected plasma equivalent was increased from 6 to 20 μL; conventional column trapping for compound enrichment and removal of matrix constituents was combined with high-pressure analytical separation using small particle columns to improve resolution and signal-to-noise ratio. Quantitation limits were thus lowered to between 5 and 20 pg/mL, offering the possibility to provide bioanalytical support for microdosing studies in humans. Excellent assay quality and robustness were achieved by both methods.

Abstract
Fentanyl is a potent analgesic drug in relieving chronic pain in patients. In this report, we present a simple, reliable and sensitive LC-ID/MS method for the quantification of fentanyl in human plasma. LC-ID/MS analysis was carried out on a triple quadrupole mass spectrometer operated in positive electrospray ionization multiple-reaction-monitoring using the transitions m/z 337.6 --> 187.9 for fentanyl and m/z 342.6 --> 187.9 for the internal standard (D5-fentanyl). The calibration curve covered the range 0.02-10 ng/mL. The intra- and inter-batch precision were less than 6.739 and 3.126% for fentanyl and IS, with accuracy from 94.16 to 102.0%. The lower limit of quantification was identifiable and reproducible at 0.02 ng/mL. The validated method offered increased sensitivity and wide linear concentration range. This method was successfully adopted for the evaluation of bioequivalence of two fentanyl transdermal preparations after single dose administration to 20 Chinese pain-patients.

Abstract
Hydrophilic interaction chromatography (HILIC) has, in recent years, been shown to be an important supplement to reversed-phase liquid chromatography for polar analytes. HILIC, in conjunction with tandem mass spectrometry (MS/MS), has been steadily gaining acceptance in the analysis of polar compounds from complex biological matrices. This hyphenated technique offers the advantages of improved sensitivity by employing high organic content in the mobile phase, shortened sample preparation time with direct injection of the organic-solvent extracts of biological samples and the potential for ultra-fast analysis because of low-column backpressure. This article reviews recent challenges presented by HILIC, advancements in the better understanding of retention characteristics of analytes with different mobile- and stationary-phase compositions and solutions to ion suppression and interference problems encountered in HILIC–MS/MS assays. Applications of HILIC–MS/MS are summarized, including those for pharmacokinetic studies, metabolic studies, therapeutic drug monitoring and clinical diagnostics.
