Abstract

Objective: development and validation of a method for the quantitative determination of local anesthetics in blood plasma using high performance liquid chromatography and mass spectrometry.

Material and methods. The objects of the study were lidocaine, bupivacaine and ropivacaine. Mepivacaine was used as an internal standard. The quantitative determination of drugs in blood plasma was carried out using an Agilent Technologies 1260 Infinity II high performance liquid chromatograph and an AB Sciex 3200 QTrap MD mass spectrometer. A Phenomenex Synergi 4 μm Fusion-RP 50 ×2 mm chromatographic column was used. A mixture of deionized water and acetonitrile with the addition of 0.1% formic acid was used as the mobile phase. The choice of the sample preparation method was based on the obtained data on the degree of extraction of analytes and the matrix effect. At the development stage, protein precipitation methods with acetonitrile and methanol were compared, as well as liquid extraction.

Results. Local anesthetics were detected by the corresponding MRM transitions: bupivacaine – m/z 289.1→140.2, ropivacaine – m/z 275.1→126.2, lidocaine – m/z 235.1→86.2, mepivacaine (internal standard) – m/z 247.1→98.1. The following chromatographic parameters were used: mobile phase – 70% aqueous solution of acetonitrile with the addition of 0.1% formic acid, flow rate – 300 μl/min, chromatographic column temperature – 40 °C, sample injection volume – 10 μl, total analysis time – 5 minutes. The retention times of bupivacaine, ropivacaine and lidocaine averaged 1.1 minutes. Extraction of local anesthetics from blood plasma was carried out with hexane. The analytical range of the developed method was from 1 to 1000 ng/ml for bupivacaine, ropivacaine and lidocaine. The developed technique is characterized by speed of execution, selectivity, reproducibility, and accuracy.

Conclusion. The developed method for the quantitative determination of bupivacaine, ropivacaine, and lidocaine in blood plasma fully complies with the requirements of domestic and foreign regulatory documents and can be used to conduct therapeutic drug monitoring of local anesthetics and establish individual pharmacokinetic characteristics of drugs.
