In the field of biomedical science, regulatory science is an essential component for ensuring the safety and effectiveness of drugs and medical devices. However, there are also several other terms that are often used interchangeably with regulatory science, including regulatory affairs, drug development, and clinical research. Regulatory affairs encompasses all of the regulatory requirements and processes involved in bringing a new medication or medical device to market. Meanwhile, drug development refers specifically to the stages involved in developing a new pharmaceutical product, from early research and testing to regulatory approval. Clinical research, on the other hand, involves testing new medical treatments and interventions on humans to evaluate their safety and effectiveness.
