title: A Validated HPTLC Method for Determination of Ondansetron in Combination with Omeprazole or Rabeprazole in Solid Dosage Form.
abstract: A simple, precise, accurate and rapid high performance thin layer chromatographic method has been developed for the simultaneous estimation of ondansetron combinations in solid dosage form with omeprazole and rabeprazole, respectively. The method involved separation of components by TLC on a precoated silica gel 60 F(254) using a mixture of dichloromethane:methanol (9:1) as a mobile phase. Detection of spots was carried out at 309 nm and 294 nm for ondansetron with omeprazole and ondansetron with rabeprazole combinations, respectively. The mean retardation factor for ondansetron and omeprazole were found to be 0.42+/-0.02, 0.54+/-0.03, respectively while for ondansetron and rabeprazole, 0.41+/- 0.02 and 0.51+/-0.02, respectively. The linearity and range was 0.1 to 0.5 mug/spot for three drugs. The method was validated for precision, accuracy and reproducibility.
