Fentanyl 53-61 interleukin 17F Homo sapiens 77-81 8807541-4 1996 The assay was linear over the clinically relevant plasma range of 2-2000 ng ml-1 for alfentanil and 2-100 ng ml-1 for fentanyl and has the sensitivity and specificity necessary to determine plasma concentrations of these compounds. Fentanyl 118-126 interleukin 17F Homo sapiens 109-113 2669904-5 1989 Mean plasma fentanyl concentrations at 12 and 24 h were within the therapeutic range (1.5 and 2.0 ng ml-1, respectively). Fentanyl 12-20 interleukin 17F Homo sapiens 101-105 3756054-6 1986 Plasma fentanyl concentrations, measured by radioimmunoassay were between 1 and 3 ng ml-1 until the infusions were discontinued.
