ABSTRACT:
A simple, precise, accurate and reproducible spectrophotometric method has been developed for  simultaneous estimation of Paracetamol (PCM) and Propyphenazone (PP) by employing first order derivative zero crossing method in Methanol. The first order derivative absorption at 249 nm (zero cross point of Paracetamol) was used for quantification of Propyphenazone and 274 nm (zero cross point of Propyphenazone) for quantification of Paracetamol. The linearity was established over the concentration range of 1-12 µg/ml and 5-24 µg/ml for Paracetamol and Propyphenazone with correlation coefficient r2 0.999 and 0.996, respectively. The mean % recoveries were found to be in the range of 100.48-102.119% and 100.448-102.713 % for Paracetamol and Propyphenazone, respectively. The proposed method has been validated as per ICH guideline and successfully applied to the estimation of Paracetamol and Propyphenazone in their combined pharmaceutical dosage form.
