Oxycodone is a semisynthetic opioid analgesic used in pain management. In the following method, gas chromatography-mass spectrometry (GC-MS) is used to determine the presence and concentration of the drug in blood and urine. The specimens are fortified with deuterated internal standard and a five-point calibration curve is constructed. Specimens are extracted using mixed-mode solid phase extraction and derivatized with N,O-bis(trimethylsilyl)trifluoroacetamide (BSTFA) producing trimethylsilyl derivatives. The final extracts are then analyzed using selected ion monitoring GC-MS.
