ABSTRACT

Objectives:The efforts were made to develop a HPLC analytical method for the simultaneous quantitative estimation of aspirin and clopidogrel and aim to identify and estimate the degradation of the drugs under the various stress conditions recommended by ICH guideline. Materials and Methods:The separation of two drugs were done by using LC- 22AD liquid chromatograph having SPD- 22A UV-vis detector on C 8 (4.6 x 52 mm) column which was connected with loop 22µl and with HPLC-Dell system. Mobile phase consisted of acetonitrile: buffer in the ratio of 1352:652 v/v. Flow rate was .13 ml/min and detection were done at 2 22 nm. Proportions of solvents and adjustment of mobile phase was carried out by screening. Results:The chromatographic separation of aspirin was noted at 4. 299 minutes with average USP tangent of 81313 2.246 and clopidogrel was at 2.726 min with average of 886.21397 tangent. A linear correlation was observed between concentration of aspirin and clopidogrel with their dilutions i.e r 2 = 2.9986 and 2.9996 respectively. The outcome of study, with limit of detection 2.258 and 2.278 µg/ml and limit of quantification 2. 7 and 2. 56 µg/ml, for aspirin and clopidogrel revealed the repeatability, reproducibility and robustness of the method. Stability indicating parameters were tested by ICH guideline.Conclusion:It is concluded that the method is linear, reproducible, robust, rugged and stability-indicating for simultaneous calculation. It can be used as a routine quality control method for combined pharmaceutical dosage form and for its kinetic studies.
