Research Journal of Pharmaceutical Dosage Forms and Technology

Analytical method development followed by method validation is an important process in the drug discovery. Although the drug shows good potency, lack of validated analytical method will not allow the drug to enter into the market. This is to ensure the quality and safety of the drug. The main objective of this review is to give an idea about the old and novel techniques available for the analysis of drugs in their raw material and formulated forms, check the stability of the drugs in the presence of the excipients and other stress conditions experienced during their shelf life period. Analytical methods development and validation play important roles in the discovery, development and Manufacture of pharmaceuticals. Method development is the process of proving that an analytical method is acceptable for use to measure the concentration of an API in a specific compounded dosage form which allows simplified procedures to be employed to verify that an analysis procedure, accurately and consistently will deliver a reliable measurement of an active ingredient in a compounded preparation.
