Abstract

A simple, sensitive and accurate spectrophotometric method of determination of Ranitidine-HCl (RNH) in pure
form and its pharmaceutical formulation. Was used in this studyThe method is based on the formation of (RNH)
complex. The reaction between the Ranitidine-HCl with the mixture of metol and potassium hexacyanoferrate (ΙΙΙ) was
evaluate metol ( Nmethyl – p - aminophenosulphate ) for the spectrophotometric determination of the Ranitidine -
HCl . The maximum absorbance of the colored complex occurred at λ = 540nm. Reaction conditions have been
optimized to obtain (RNH) complex of high sensitivity and longer stability. Under optimum conditions the absorbance
of the (RNH) complex where found to increase linearly with the increase in concentration of the Ranitidine-HCl which
corroborated with correlation coefficient value. Of 0.09995with concetration ranges of(2-90) μg /ml relative standard
deviation and relative error of prediction for drug were lower . The proposed method was successfully applied to
determine of the selected Ranitidine-HCl in pure form and pharmaceutical formulations with good precision and
accuracy compared to standard method as revealed by t- and F- values , the results obtained agree well with the labeled
contents.
