A simple, accurate and rapid method for the
quantitative determination of five ranitidine drugs in pharmaceutical
formulations (Tablets and Ampoules) is proposed. The supporting
electrolyte was acetic acid-sodium acetate buffer solution (pH 5.2). An
excellent linear relationship was obtained between the concentration and
current with correlation coefficient 0.9996. Good agreement was
obtained between the results with the d.c. polarograhic method and those
by the manufacturer's method of assay.
