Electrospray ionisation quadrupole ion-trap mass spectrometric (ESI-MS) characterisation of the anti-psychotic drugs chlorpromazine, trifluoperazine, flupenthixol, risperidone and the antidepressant/internal standard trimipramine is presented and possible mechanisms for the observed MSn fragmentation patterns proposed. A validated liquid chromatography (LC)-MS-MS method is then applied to the detection and determination of these drugs in the hair of a patient under clinical treatment for schizophrenia. Chlorpromazine, trifluoperazine and flupenthixol are identified and determined in this hair sample following alkaline degradation of the matrix, solvent extraction and LC-MS-MS using trimipramine as internal standard.
