【 摘 要 】

Present work describes development and validation of HPLC-DAD method for the analysis of a complex mixture consisting phenylephrine hydrochloride (PHE), paracetamol (PAR), caffeine (CAF) and levocetirizine (LEV). Chromatographic separation was achieved using a Kinetex-C18 column involving gradient elution, the mobile phase composed of 10mM phosphate buffer (pH 3.3) and methanol. The three step gradient program started with step-1 initially with 2% (by volume) methanol and 98 % phosphate buffer (pH 3.3) for first 5 minutes. In step-2 methanol concentration changed linearly to 80% in next 12 minutes the analysis was concluded by step-3 changing methanol to 2% in next 8 minutes. The method was linear in concentration ranges of 50 to 200 % of labeled claims with r2 near to 1. Developed method proved to be precise for inter and intra-day studies the %RSD values were < 2 , accuracy studies by standard addition at 80, 100 and 120% levels resulted in recoveries of standard near to 100%. The method was selective with no interferences from placebo; robustness of method was proved by no significant alteration in system suitability parameters. The LOD values for PHE, PAR, CAF and LEV were 0.13, 0.51, 0.05 and 0.05 and LOQ were 0.39, 1.53, 0.15 and 0.15 respectively. The study concluded a validated HPLC method for analysis of complex mixture consisting PHE, PAR, CAF and LEV in bulk, tablet and dissolution samples in simulated gastric fluid (SGF).
