Morphine, Hydromorphone and 6-Monoacetylmorphine (6-MAM) in Plasma

This AppNote presents a Method that could be used for a routine analysis of Plasma Samples or (whole blood samples after changing the extraction procedure) for the presence of Morphine, Hydromorphone (isobaric compounds) or 6-MAM (an indicator of Heroin use).

Sample Preparation: To a spiked Plasma Sample (1mL), 1mL of an Ammonia solution (0.1% v/v) was added and vortex-mixed for 30 seconds to alkalize the Plasma. Then, the alkalized Plasma Sample was extracted with two 4mL Ethyl Acetate aliquots by vortex for 5 minutes, and  centrifuged at 4000 rpm for 8 minutes at room temperature. The supernatant was separated and evaporated to dryness under a gentle stream of Nitrogen. The residue was reconstituted with 200µL Mobile Phase, and a 1µL aliquot of the reconstituted solution was injected into the LC– ESI-MS for analysis.

Note: Morphine is used as an analgesic drug in the treatment of the severe pain. Hydromorphone, a semi-synthetic derivative of Morphine is used in cases of Morphine-resistant Cancer-related pain and 6-Monoacetylmorphine (6-MAM) is a specific indicator for Heroin use. All three drugs remain the selected substances in monitoring of drug abuse and addiction. Heroin use remains a serious public health issue which accounts for a substantial proportion of the health costs. Analysis of Plasma Samples for the presence of the three substances is essential in assessing short or long term exposure to the drugs.
