Abstract

A simple, precise, accurate, and rapid high-performance thin layer chromatographic method has been developed and validated for the simultaneous quantitation of flunarizine dihydrochloride and propranolol hydrochloride in a combined capsule dosage form. The method was carried out on precoated silica gel 60 F 254 TLC aluminum plate, (20×10 cm 2 ). The solvent system was ethyl acetate:methanol:glacial acetic acid in the proportion of 8:1:1, (v/v/v). Rf value for flunarizine dihydrochloride and propranolol hydrochloride was found to be 0.62±0.02 and 0.18±0.02, respectively. The linearity regression analysis for calibration showed 0.999 and 0.999 for flunarizine dihydrochloride and propranolol hydrochloride with respect to peak area and height in the concentration range of 50-350 ng/spot and 500-3500 ng/spot, respectively. Accuracy of recovery studies was found to be 98-100.28 and 99.11-99.45% for flunarizine dihydrochloride and propranolol hydrochloride, respectively. The amounts of drug in marketed formulation were 100.5 and 101.25% of flunarizine dihydrochloride and propranolol hydrochloride, respectively. The method developed can be used for routine analysis in bulk drug and capsule dosage form.
