Objective: Since the 1960s, fentanyl has been used to replace morphine and other opioids due to its higher potency in the treatment of acute pain; since the 1990s, it has also been administrated to control chronic pain by using transdermal fentanyl device system. It is crucial and of utmost importance and crucial to validate a sensitive method for the quantification of trans dermal fentanyl in human plasma. Materials and methods: A rapid, simple and sensitive high performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS) method has been established and validated for the determination of transdermal fentanyl in human plasma using fentanyl-D5 as an internal standard (IS). Following liquid-liquid extraction (LLE) with n-hexane, the extracts were separated on a Thermo Hypersil ODS(C18) column (2.1 x 150 mm i.d., 5 gm) interfaced with a triple-quadrupole tandem mass spectrometer using positive electrospray ionization. Results and conclusions: Quantification of fentanyl was carried out by multiple reaction monitoring (MRM) of the transitions at m/z 337.1 -> 188.0 for fentanyl and 341.9 -> 187.9 for IS. The lower limit of quantification was 9.75 pgxmL(-1), and the test showed a linear range of 9.75 - 10,000 pgxmL(-1). The validated method was subsequently applied to a bioequivalence (BE) study in 24 healthy Chinese volunteers by using transdermal fentanyl patches.
