Abstract A novel, simple and economic reverse phase high performance liquid chromatography (RPHPLC)method has been developed for the estimation of Paracetamol, nimsulide and tizanidine in bulkand tablet dosage forms with greater precision and accuracy. Separation was achieved on C18 column(250X4.6mm , 5μm) using gradient mobile phase Sol-A: buffer (weighed accurately 1gm of ammoniumacetate in to 1000mL of HPLC grade water) and Sol-B: acetonitrile gradient program (0-6min, sol-A:80-37; 6-10min- sol-A: 37-80 and 10-15min- sol-A: 80-80), pumped in to the column at flow rate of 1ml/min and the detection of eluent from the column was carried out using variable wavelengthdetector at 230nm. The total run time was 15 min and the column was maintained at ambienttemperature. The retention times of paracetamol, tizanidine and nimsulide were 3.0min, 5.3 and8.6min, respectively. The standard curves were linear over the concentration range of 12.5-75μg/mland the % RSD of intraday and inter day precision was found to be good. The method was validated asper ICH guidelines. Validation studies demonstrated that the proposed RP-HPLC method is simple,specific, rapid, reliable and reproducible. The high recovery and low relative standard deviationconfirm the suitability of the proposed method for the routine quality control analysis in bulk andtablet dosage forms.
