Fatal intoxications by acenocoumarol, phenprocoumon and warfarin: method validation in blood using the total error approach.

A simple high-performance liquid chromatography (HPLC) method with ultraviolet (UV) detection has been developed and validated for simultaneous identification and quantification of three antivitamin K drugs (acenocoumarol, warfarin and phenprocoumon) in whole blood. The aim of this development was to propose an analytical technique adapted to the situations of forensic toxicology, i.e.

Simultaneous determination of five beta-lactam antibiotics (cefepim, ceftazidim, cefuroxim, meropenem and piperacillin) in human plasma by high-performance liquid chromatography with ultraviolet detection.

Monitoring of plasma antibiotic drugs is useful for better clinical management in infected patients, particularly in intensive care units. A simple and sensitive high-performance liquid chromatography (HPLC) method with ultraviolet (UV) detection has been developed and validated for simultaneous quantification of five beta-lactam antibiotics in human plasma: cefepim, ceftazidim, cefuroxim, meropenem and piperacillin. The plasma sample, after spiked with ceforanid as an internal standard (IS), was submitted to a solid-phase extraction (SPE) prior to HPLC analysis.
