A simple precise, rapid accurate and sensitive non-aqueous potentiometric titration method was developed for quantitative determination of clopidogrel bisulphate from pharmaceutical dosage form. The titration was carried out using standardized 0.1 N perchloric acid. The proposed method was found to be precise with % RSD <1 (n = 6). The method showed strict linearity (r2 > 0.9999) between 20 % to 100 % of 0.100 mg of drug substance weight. The percentage recovery of clopidogrel bisulphate in the optimized method was between 100.0 to 100.416 %. The method is also found to be rugged when checked by different analysts and using different lots of reagents and different makes of titrators.

The titration was carried out using standardized 0.1 N perchloric acid. The proposed method was found to be precise with % RSD <1 (n = 6). The method showed strict linearity (r2 > 0.9999) between 20 % to 100 % of 0.100 mg of drug substance weight. The percentage recovery of clopidogrel bisulphate in the optimized method was between 100.0 to 100.416 %. The method is also found to be rugged when checked by different analysts and using different lots of reagents and different makes of titrators.
