[PMID: 37360102 PMCID: PMC10285229 DOI: 10.1016/j.heliyon.2023.e17230] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Revised: 06/06/2023] [Accepted: 06/12/2023] [Indexed: 06/28/2023] Open
Abstract
A sensitive, convenient, rapid and economic liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed to determine cinacalcet concentration in human plasma. A stable isotope cinacalcet (cinacalcet-D3) was selected as internal standard and the analytes were extracted from plasma samples by a one-step precipitation procedure. Chromatography separation was conducted on an Eclipse Plus C18 column by gradient elution with mobile phase of methanol-water-ammonium formate system at a constant flow rate of 0.6 mL/min. Mass spectrometric detection was conducted by multiple reaction monitoring using positive electrospray ionization. Cinacalcet concentrations in human plasma were determined over the concentration range of 0.1-50 ng/mL. The accuracies of lower limit of quantification (LLOQ) and quality control samples were all within the range of 85-115%, and the inter- and intra-batch precisions (CV%) were all within 15%. The average extraction recovery rates were 95.67-102.88%, and the quantification was not interfered by the matrix components. The validated method was successfully applied to determined cinacalcet concentrations in human plasma from secondary hyperparathyroidism patients.

Abstract
Background Therapeutic drug monitoring (TDM) of antibiotics in children is of fundamental importance for effective patient management. The use of dried blood spot (DBS) offers a number of advantages over conventional blood collection. The aim of this study is to develop and validate a method to measure piperacillin/tazobactam in DBS. Results The analysis was performed by using LC–MS/MS operating in multiple reaction monitoring mode. The method has been validated by applying EMA guidelines and its suitability for TDM was evaluated by using samples from low birth weight neonates. Conclusion This paper describes a fast and cost-effective micromethod for the simultaneous determination of piperacillin/tazobactam levels on dried blood spot that is suitable for TDM in children.
