Biological products are medical products derived from living organisms, including humans, animals, or microorganisms. They can include a variety of substances such as vaccines, blood components, and therapeutic proteins. These products are used to prevent, diagnose, or treat diseases and are often more complex than traditional chemical drugs. The development of biological products involves advanced techniques like genetic engineering and cell culture. Regulatory agencies, such as the FDA in the United States, ensure their safety and effectiveness before they can be used in medical treatments. This rigorous process helps maintain high standards for patient care.
