title: High-performance liquid chromatographic determination of bromazepam in human plasma.
abstract: An assay using high-performance liquid chromatography has been developed for the determination of bromazepam in plasma. After a single-step extraction from basified samples with dichloromethane, using decarboxyloflazepate as an internal standard, samples were analysed using a reversed-phase Nova Pak 5-microns column with a mobile phase of methanol - phosphate buffer (60 + 40) adjusted to pH 7.6. The drugs were detected at 239 nm and the limit of detection was found to be 3 micrograms l-1 for bromazepam. The method is simple, rapid and sensitive and permits bromazepam levels in clinical and pharmacokinetic studies to be monitored.
