Development Drug: How Drug Are Tested, Formulated, Produced and Regulated

Drug discovery is the systematic procedure of identifying a chemical compound that possesses therapeutic properties for the purpose of healing and treating diseases. This process involves the identification of candidates, the synthesis, characterization, validation, optimization, screening, and testing to assess the therapeutic effectiveness. After a molecule has proven its significance in these investigations, it will initiate the process of developing medication. Preclinical development precedes clinical testing. The process of developing a new drug must advance through several stages in order to create a medication that is both safe and effective, and that meets all regulatory requirements. The essay highlights the lengthy, difficult, and costly nature of producing new medicines. It underscores the need to consider various biological targets for each authorized treatment. The validation of analytical method is essential for its development, whereby it is extensively tested for specificity, linearity, accuracy, precision, range, limit of detection, limit of quantitation, and robustness. Thus, the development and validation of analytical methods allows one to confirm that accurate and reliable measurement of the potency a pharmaceutical preparation can be performed. The present review highlights the process of drug development, its phases, and analytical methods, including chromatographic, spectroscopic, and electrochemical techniques, which have been applied in the analysis of pharmaceuticals.
