Drug production refers to the process of creating pharmaceutical substances that are used to treat, prevent, or diagnose diseases. This process involves several stages, including research and development, formulation, and manufacturing. Pharmaceutical companies often conduct extensive testing to ensure the safety and efficacy of these drugs before they can be approved for public use. The production of drugs can involve both synthetic methods, where chemicals are combined to create new compounds, and natural methods, where substances are extracted from plants or other organisms. Regulatory agencies, such as the Food and Drug Administration (FDA), oversee the approval and monitoring of drug production to ensure that products meet safety standards.
