    Abstract:
    A simple high-performance liquid chromatographic method for determination of ticlopidine in human plasma using ultra violet detection was developed. The separation of the investigated compound and internal standard was achieved on a C18 BD column with a 0.01 M potassium dihydrogen phosphate buffer (pH 4)-acetonitrile-methanol (20:40:40, v/v) mobile phase. The detection was performed at 215 nm. The compounds were isolated from plasma by Bond Elut C18 solid-phase extraction, the mean absolute recovery was 84.9%. The limit of quantitation was 10 ng ml(-1), the limit of detection was 5 ng ml(-1). The bioanalytical method was validated with respect to linearity, within- and between-day accuracy and precision. system suitability and stability. All validated parameters were found to be within the internationally required limits. The developed analytical method for ticlopidine was found to be suitable for application in pharmacokinetic studies and human drug monitoring.
