Objective: To develop a simple, precise and accurate reverse phase high performance liquid chromatographic method for the evaluation of Clopidogrel (CLP) and Pantoprazole Sodium (PAN) succeeding degradation studies as per the ICH guidelines.

Methodology: The degradants and active drugs were separated by thin layer chromatography and exposed to structural elucidation by mass spectrometry with electron spray ionization (ESI) technique. The degradation products were detected in alkali and acid hydrolysis for Clopidogrel; whereas Pantoprazole Sodium exhibited degradation on exposure to light.

Results and Discussion:The base peak of CLP with m/z of 501.6 was formed in positive ESI mode. The daughter ion of CLP was observed at m/z of 418.3. Two degradants with m/z of 524.1 and m/z of 507.8 were formed by acid hydrolysis to give a carboxylic acid derivative and another by dehydrogenation respectively. Degradation product with m/z of 553.3 was di-sodium adduct of CLP and was formed in alkaline hydrolytic condition. The base peak of photo degradant of PAN with m/z of 419.1 was formed in positive ESI mode showed same m/z value of the base peak of PAN.

Conclusion:The obtained results indicate that structural modification occurred in PAN molecule due to photolytic degradation. This article sheds light on the mechanisms for the formation of degradation products for CLP and PAN. A linear gradient mode of elution was used for separation of CLP, PAN and their degradants on a C18 column using a PDA detector. The developed and validated method was used for the analysis of marketed tablets of CLP and PAN in combination.
