Background: Gliclazide Impurity A (GI-A) is one of the gliclazide impurities, as described in the European Pharmacopoeia. Objective: The objective of this study was to develop and validate simple, robust and accurate reversephase high-performance liquid chromatography (RP-HPLC) method for estimation of gliclazide along with GI-A in bulk by optimising chromatographic parameters using Box Behnken design in response surface methodology. Method & Results: Box Behnken design was employed for optimizing flow rate, injection volume and strength of the buffer in order to minimize retention time of both gliclazide and GI-A. The optimized strength of orthophosphoric acid buffer in a mixture of Acetonitrile (50:50 v/v), flow rate and injection volume were found to be 25mM, 1mL/min, 20
