Abstract

Buclizine hydrochloride from its tablet dosage form was estimated by developing a novel validated indirect spectrofluorimetric method. Here the Buclizine hydrochloride was derivatized into nitro compound using nitrating mixture with an aid of heat which showed good fluorescence in water at 446 nm after excited at 350 nm. The calibration graph showed linear over the range 200-1000 ng/ml. The assay of buclizine hydrochloride in marketed formulations was found to be 98.96 ± 0.1586. Recovery values were close to 100% with the % RSD values of 0.432% and 0.673% at 50% and 100% level respectively. From the results of validation it was observed that the method was found to be simple, accurate, sensitive and reproducible. Hence the proposed method can be used for routine quality control analysis.
