Interaction Studies of Moxifloxacin with Anti-diabetic Drugs and Application of RP-HPLC in Analysis

Aim: Simple RP-HPLC method was developed and validated for the simultaneous estimation of Glimepiride, Glibenclamide and Moxifloxacin in pharmaceutical preparation. Materials and Methods: Mediterranean C-18 column with dimensions of 150mmx4.6mm was used with HPLC Shimadzu_ LC-20 AT model, Version 1:62 is used for processing of chromatograms at room temperature (25 +/- 2degree celsius). 1 mL per minute was the flow rate and detector were set at 254nm with mobile Phase consisting of 85:10:5 v/v methanol: water: acetonitrile. Results: The developed method proved to be accurate, simple, effective precise and reproducible. One way ANOVA was also applied for further confirmation of the results. Conclusion:The method is applicable for the routine analysis of drugs in API and in formulation and for studying in vitro interaction studies.
