title: High-performance liquid chromatographic assay for suprofen, a potent new analgesic, in plasma.
abstract: A simple, rapid, high-performance liquid chromatographic (HPLC) determination of therapeutic levels of suprofen, a potent new analgesic, in human plasma is described. After a simple extraction, the compound is analyzed by HPLC using a reversed-phase column and a UV detector. Quantitation is accomplished using an external standard; peak areas are determined by computer. An average recovery of 80.0 +/- 8.5% SD of the drug was obtained over the 0.2-20.0-microgram/ml range. Maximum sensitivity is approximately 0.1 microgram/ml. No interference is encountered from any known metabolite of suprofen.
