Abstract

A simple, precise and rapid reverse-phase HPLC method has been developed and subsequently validated for the simultaneous estimation of thiocolchicoside and dexketoprofen trometemol from their combination drug product. The proposed RP- HPLC method utilizes a Oyster BDS C 18 , 5 μm, 250 mm × 4.6 mm i.d. column, at ambient temperature; optimum mobile phase consisted of methanol:ammonium dihygrogen phosphate buffer (55:45, v/v), pH adjusted 7.3 with triethyl amine; effluent flow rate monitored at 1.5 mL min-1, and detection at 290 nm with UV-Visible detector. The described method was linear over the range of 10-60 μg/ml and 12.5-75 μg/ml with co-efficient of correlation, (r 2 )=0.998 and (r 2 )=0.997 for thiocolchicoside and dexketoprofen trometemol, respectively. The mean recovery was found to be 100.51±1.30% and 99.69±0.86% for thiocolchicoside and dexketoprofen trometemol, respectively. The intermediate precision data obtained under different experimental setup, the calculated value of coefficient of variation (CV, %) was found to be less than critical value. The proposed method can be useful in the quality control of bulk manufacturing and pharmaceutical dosage forms.
