High-performance liquid chromatographic determination of pipotiazine in human plasma and urine.
A high-performance liquid chromatographic method has been developed for the determination of pipotiazine in human plasma and urine. After selective extraction, pipotiazine and the internal standard (7-methoxypipotiazine) and chromatographed on a column packed with Spherosil XOA 600 (5 micrometers) using a 7:3 (v/v) mixture of diisopropyl either--isooctane (1:1, v/v + 0.2% triethylamine and diisopropyl ether--methanol (1:1, v/v) + 0.2% triethylamine + 2.6% water. The eluted compounds are measured by fluorescence detection. The sensitivity of the method was established at 0.25 ng/ml pipotiazine in plasma and 2 ng/ml pipotiazine in urine (C.V. less than 5%). The method has been successfully applied to a pharmacokinetic study following a single oral administration of 10 mg of pipotiazine.[1]References
