A sensitive and specific HPLC method with fluorescence detector has been developed for the analysis of atenolol in plasma using a reverse phase column (ODS, 250 x 4.6 mm, 10 μm). Atenolol levels were measured using its excitation and emission maxima at 276 nm and 302 nm, respectively. The method has a linearity range of 50-1000 ng/ml and recovery was found to be 95.7%. This method has been successfully used for the bioequivalence study of atenolol tablets (25 mg). Cmax, tmax and AUC0-, of the test formulation statistically does not show significant difference from the standard formulation.
