Development And Validation

Development of a method is crucial for discovery, development, and analysis of medicines in the pharmaceutical formulation. Method validation could also be thought to be one in all the foremost well-known areas in analytical chemistry as is reproduced within the substantial variety of articles submitted and presented in peer review journals every year. Validation of an analytical procedure is to demonstrate that it's appropriate for its intended purpose. Results from method validation are often wont to decide the quality, reliability and consistency of analytical results. Analytical methods need to be validated or revalidated. This review describes general approach towards validation process and validation parameters to be considered during validation of an analytical method. It also refers to various regulatory requirements like WHO, USFDA, EMEA, ICH, ISO/IEC. The parameters described here are according to ICH guidelines which include accuracy, precision, specificity, limit of detection, limit of quantification, linearity range and robustness.

In this article we describe development and validation of stability indicating, accurate, specific, precise and simple Ion-pairing RP-HPLC method for simultaneous determination of paracetamol and cetirizine HCl along with preservatives i.e. propylparaben, and methylparaben in pharmaceutical dosage forms of oral solution and in serum. Acetonitrile: Buffer: Sulfuric Acid (45:55:0.3 v/v/v) was the mobile phase at flow rate 1.0 mL min-1 using a Hibar® Lichrosorb® C18 column and monitored at wavelength of 230nm. The averages of absolute and relative recoveries were found to be 99.3%, 99.5%, 99.8% and 98.7% with correlation coefficient of 0.9977, 0.9998, 0.9984, and 0.9997 for cetirizine HCl, paracetamol, methylparaben and Propylparaben respectively. The limit of quantification and limit of detection were in range of 0.3 to 2.7 ng mL-1 and 0.1 to 0.8 ng mL-1 respectively. Under stress conditions of acidic, basic, oxidative, and thermal degradation, maximum degradation was observed in basic and oxidative stress where a significant impact was observed while all drugs were found almost stable in the other conditions. The developed method was validated in accordance with ICH and AOAC guidelines. The proposed method was successfully applied to quantify amount of paracetamol, cetirizine HCl and two most common microbial preservatives in bulk, dosage form and physiological fluid.
