    Abstract:
    A rapid and sensitive high-performance thin-layer chromatographic (HPTLC) method has been developed for the measurement of sparfloxacin in human plasma and its use for pharmacokinetic study has been evaluated. Detection and quantitation were performed without using an internal standard. A single stage extraction procedure was followed for extracting sparfloxacin from plasma and a known amount of the extract was spotted on precoated silica gel 60 F254 plates using a Camag Linomat IV autosampler. Sparfloxacin was quantified using a Camag TLC Scanner 3. The recovery study of authentic analytes added to plasma at 0.1 to 0.8 microgram ml-1 was 94.9 +/- 0.98% and the lowest amount of sparfloxacin that could be detected was 50 ng ml-1 plasma. The method provides a direct estimate of the amount of sparfloxacin present in plasma. The method was used for the determination of plasma levels as well as pharmacokinetic parameters of sparfloxacin after oral administration of two marketed preparations to healthy volunteers.
