Abstract
A stability-indicating isocratic RP-HPLC method was developed and validated for the determination of Brinzolamide in bulk drugs using Hemochrom C18 column (150mm×4.6 mm, 5µm) with mobile phase consisting of 1mM ammonium formate: acetonitrile (76:24 v/v) with a flow rate of 1mL/min (UV detection at 254 nm). Linearity was observed over the concentration range 5-100 µg/mL (r2=0.9994) with regression equation y=15043x-3093. Brinzolamide was subjected to stress conditions including acidic, alkaline, oxidation, photolysis, and thermal degradation. Brinzolamide is more sensitive towards oxidative degradation. The method was validated as per the ICH guidelines.
