Abstract: | A capillary electrophoresis (CE) procedure has been developed for the determination of piracetam in human plasma. Analyses were performed on an uncoated silica capillary using borax buffer modified with the addition of α-cyclodextrin. The detection was UV, operated at 200 nm. The detection limit of the authentic samples was 1 μg/ml. The calibration curve was linear over a range of 4 to 24 μg/ml (r=0.997). Inter-assay R.S.D. was below 9.3%. The described method has been successfully applied to the quantitative determination of piracetam in human plasma and should be useful for clinical and bioavailability investigations. |
