抜粋

A high-performance liquid chromatographic (HPLC) method for the quantitative determination of epinastine, a non-sedating histamine H1 receptor antagonist, in rat plasma, was developed. A 100-μl volume of plasma sample was spiked with a solution of internal standard (diphenidol) and extracted with dichloromethane under alkaline conditions. The extract was applied onto the HPLC system and detected by ultraviolet absorption at a wavelength of 220 nm. The linearity of the calibration curve was preserved over the concentration range of 20-1000 ng/ml. Both intra-assay variation and relative error were less than 5% for the plasma sample containing 50 ng/ml or 1000 ng/ml of epinastine hydrochloride. The analytical method presented here should be useful for the investigation of the pharmacokinetic properties of epinastine, which is of clinical significance.
