DEVELOPMENT AND VALIDATION OF HPLC METHOD FOR ESTIMATION OF BRIMONIDINE TARTRATE AS BULK DRUG AND IN OPHTHALMIC FORMULATION
Journal Title: Journal of Drug Delivery and Therapeutics - Year 2017, Vol 7, Issue 7
Abstract
The optimized reverse phase high performance liquid chromatographic method was developed for estimation of Brimonidine Tartrate in bulk drug and pharmaceutical dosage form. Chromatography was performed on Kromasil C 18 ( 250 mm X 4.6 mm i.d. , 5 μm particle size) column with mobile phase citric acid monohydrate buffer:water:methanol (30:50:20 v/v/v) and pH 3 was maintained by using triethylamine. The flow rate was 1.0 ml/min. Elute was detected at 246 nm and it effectively separated at Retention Time of 5.96 min. The LOD and LOQ was 1.47 and 4.47 μg/ml respectively. A linear response was observed over the concentration range 40-80 μg/ml for Brimonidine Tartrate. Thus the proposed HPLC method was found accurate, specific, precise, robust and reproducible.
