| Summary: | A simple, fast and precise reversed phase high performance liquid chromatographic method is developed for the simultaneous determination of aceclofenac, paracetamol and chlorzoxazone. Chromatographic separation of the three drugs was performed on an Intersil C18 column (250 mm × 4.6 mm, 5µm) as stationary phase with a mobile phase comprising of 10 mM potassium dihydrogen phosphate (pH adjusted to 5.55 with ammonia): acetonitrile in the ratio 60:40 (v/v) at a flow rate of 1.0 mL/min and UV detection at 205 nm. The linearity of aceclofenac, paracetamol and chlorzoxazone were in the range of 5.00-15.00 µg/µL, 25.00-75.00 µg/µL and 25.00-75.00 µg/µL respectively. The limit of detection for aceclofenac, paracetamol and chlorzoxazone was found to be 18.0 ng/mL, 22.0 ng/mL and 9.0 ng/mL respectively whereas, the limit of quantification was found to be 55 ng/mL, 65 ng/mL and 27.0 ng/mL respectively. The recovery was calculated by standard addition method. The average recovery was found to be 99.04%, 99.57% and 101.63% for aceclofenac, paracetamol and chlorzoxazone respectively. The proposed method was found to be accurate, precise and rapid for the simultaneous determination of aceclofenac, paracetamol and chlorzoxazone |
