Area of Science:

  • Pharmacology
  • Analytical Chemistry

Background:

  • Sufentanil is a potent synthetic opioid analgesic.
  • Accurate quantification of sufentanil in biological matrices is essential for clinical and forensic applications.

Purpose of the Study:

  • To investigate the stability of sufentanil in human plasma under various storage conditions.
  • To determine the impact of storage temperature and tube type on sufentanil concentration.

Main Methods:

  • Human plasma samples were stored under different conditions (temperature, tube type).
  • Sufentanil was extracted using solid-phase extraction with Oasis MCX columns.
  • Quantification was performed using gas chromatography-mass spectrometry (GC-MS).

Main Results:

  • Significant sufentanil degradation was observed at 4°C in nonsilanized tubes within one hour.
  • Storage at -25°C in nonsilanized glass tubes for 8 hours led to an average 10.1% loss of sufentanil.
  • Degradation also occurred in silanized glass tubes at -25°C over 12 hours.

    • Conclusions:

    • Sufentanil stability is compromised by common storage conditions.
    • Non-silanized tubes and elevated temperatures accelerate sufentanil degradation.
    • Strict adherence to appropriate sampling and storage protocols is vital for reliable sufentanil measurements.
