A review on analytical method validation and its regulatory perspectives

Analytical methods plays vital role in the process of identification, separation and then quantification of chemical components in natural materials or synthetic materials based on their chemistry. The main purpose of the analytical method development and validation is to prove that proposed analytical method is accurate, specific, precise and robust in the pharmaceutical industry for analysis of a drug moiety. Analytical method development gives important information in the pharmaceutical industry, on the potency of a drug, the drug’s bioavailability, the drug’s stability and also its effects. The analytical method validation is essential for analytical method development and tested for specificity, linearity, accuracy, precision, range, detection limit, quantitation limit and robustness. In summary, analytical method development and validation confirms that an accurate, precise and reliable potency measurement of a pharmaceutical preparation can be performed.
