The hRf value of oxaprozin was 56. Quantitative determination by absorbance measurement at 286 nm. The limit of detection and quantification was 16 and 40 µg/mL, respectively. Linearity was between 33 and 433 µg/mL. The recovery was between 98.9 and 101.6 % at different spiking levels. Intra-day precision (%RSD) at different concentration levels was 0.86-1.03 % and inter-day precision 0.99-1.15 %. Oxaprozin was subjected to stress tests (acidic and alkaline hydrolysis) and the method was able to separate the degradation products from the main compound.

      Stability indicating HPTLC assay method for determination of irbesartan in pharmaceutical formulations 62nd Indian Pharmaceutical Congress Abstract No
      S. KELA*, P. DESAI, C. MODI, P. MEHTA (*Institute of Pharmacy, Nirma University, Ahmedabad 382481, Gujarat, India)

      F-255 (2010). TLC of irbesartan on silica gel with ethyl acetate – toluene – glacial acetic acid 35:15:1. Quantitative determination by absorbance measurement at 240 nm. The method was linear in the range of 200-800 ng/band. The sample was subjected to different stress conditions (acid, alkali, oxidation, thermal & photolytic). The compound was well separated from the different degradation products and could be estimated without any interference from the degradation product. The proposed stability indicating assay method was found suitable for routine quality control.
