Abstract
A fully automated HPLC assay has been developed and validated for the quantitation of verlukast, a leukotriene D4 antagonist, in human plasma. An upgraded Zymate I robotic system was utilized to perform protein precipitation and on-line injection followed by reversed-phase HPLC with fluorescence detection. Inter-day accuracy and precision were 100.8 and 4.6%, respectively, for the low quality control standards (0.125 microgram/ml). The automated robotic method was shown to be more efficient and accurate than the manual method.
