Popis: | Nail samples are an alternative to hair for long-term monitoring of drug use, although there are a limited number of studies about its applicability. This study presents the development and validation of a LC-MS/MS method for the determination of five antipsychotic drugs (clozapine, haloperidol, levomepromazine, olanzapine and quetiapine) in nail and in hair samples. Samples were washed with dichloromethane, pulverized with a ball mill, and incubated in water:acetonitrile (50:50 v/v) with horizontal agitation for 90 min. Then, samples were purified by solid phase extraction with OASIS MCX cartridges and analysed by LC-MS/MS. The analytical method was fully validated in nails and in hair, including: limits of detection (2.5 pg/mg and 2.5-10 pg/mg, respectively), limits of quantification (LOQ) (10 pg/mg and 10-20 pg/mg, respectively), linearity (LOQ to 10,000 pg/mg), selectivity (no endogenous or exogenous interferences), accuracy (97.4-106.9% and 97.3-108.2%, respectively), imprecision ( |
