The chemical stability of isoniazid in an oral liquid dosage form was studied by means of a specially developed stabilty-indicating high-performance liquid chromatographic assay method. The concentrations of the drug were directly related to peak heights, and the percent relative standard deviation based on five injections was 0.93. The products of decomposition and excipients present in the dosage forms did not interfere with the developed assay method. The preparation was stable for at least… CONTINUE READING
