Abstract
Remifentanil is a short acting opioid currently used in anesthesia and as an analgesic. This paper describes a simple, fast HPLC-MS/MS methodology that allows detection of remifentanil in low volume plasma samples. Acetonitrile protein precipitation is used for sample extraction and clean up. The assay has a lower limit of detection of 0.25 ng/mL and a 3 min run time.
