Pharmaceutical analysis is the process of testing and evaluating the chemical composition and quality of drugs and medications. This analysis ensures that pharmaceutical products meet safety standards and are effective for patient use. Techniques used in this field include chromatography, spectroscopy, and mass spectrometry, which help identify active ingredients and detect impurities. The results of pharmaceutical analysis are crucial for regulatory compliance and product development. Regulatory agencies, such as the Food and Drug Administration (FDA), require thorough testing to ensure that drugs are safe and effective before they can be marketed. This process helps protect public health and ensures that patients receive high-quality medications.
