      G. SUBRAMANIAN, CH. SRIDEVI NAIDU, Gautam MISHRA, Varadaraj BHAT, N. UDUPA* (*College of Pharmacy, Manipal, Karnataka, India)

      56th IPC 2004, Abstract No. GP-47. Stability indicating HPTLC determination of oxcarbazepine in tablet dosage form on silica gel with toluene - methanol 4:1. The Rf value of oxcarbazepine was 0.17. Quantitative determination by scanning at 255 nm. The compound was subjected to acid and alkali hydrolysis, oxidation, dry heat, and photo degradation. All degraded products were well resolved from the pure drug. The method was validated for accuracy, precision, linearity, robustness, and recovery.
