Regulatory affairs is a field that focuses on ensuring that products, especially in the pharmaceutical, biotechnology, and medical device industries, comply with laws and regulations. Professionals in this area work with government agencies, such as the Food and Drug Administration (FDA) in the United States, to facilitate the approval process for new products and maintain compliance throughout their lifecycle. These specialists are responsible for preparing and submitting documentation, conducting research, and communicating with regulatory bodies. Their work helps ensure that products are safe, effective, and meet the necessary standards before reaching consumers, ultimately protecting public health and safety.
