| Abstract:
|
A simple, accurate and precise RP-HPLC method was developed for determination of Doxofylline in
tablets and syrup dosage form. The chromatographic separation was carried out on a LichroCART LiChrosphere
100; C18 column (250mm × 4mm i.d., 5µm) using methanol: water (50:50, v/v) as mobile phase
at flow rate of 0.8ml/min .The UV detection wavelength was 275nm.Xanthinol nicotinate was used as the
internal standard. The linearity is obeyed over a concentration range of 0.05-400 µg/ml with a correlation
coefficient of 0.9999.The LOD and LOQ were determined for both the tablet and syrup formulations. The
proposed method is validated by determining accuracy, precision, stability, specificity and system suitability
parameters. The method was used successfully for the determination of Doxofylline in both tablet
and syrup dosage form. The advantage of this method is that the mobile phase is simple, method is fast,
cost effective and has a wide range of linearity; making it suitable for routine analysis in laboratories.
