It is necessary to find the content of each drug either in bulk or single or combined dosage forms for purity testing. It is also essential to know the concentration of the drug and it’s metabolites in biological fluids after taking the dosage form for treatment. The area of developing and validating an analytical method is to ensure a suitable method for a particular analyte more specific, accurate and precise. The main aspiration for that is to improve the conditions and parameters, which should be followed in the development and validation.
KEYWORDS: Accurate, Precise, Purity, Validation and Parameters.
