Final answer:
Phase III certification in medicine is typically administered by regulatory agencies such as the U.S. Food and Drug Administration (FDA) or the European Medicines Agency (EMA) based on the results of clinical trials and safety surveillance activities.
Step-by-step explanation:
Phase III certification in medicine is typically administered by regulatory agencies such as the U.S. Food and Drug Administration (FDA) or the European Medicines Agency (EMA). These agencies require pharmaceutical companies to conduct clinical trials to evaluate the safety and efficacy of new drugs before they can be approved for use by the public. Phase III trials involve testing the drug on a larger number of patients to gather more data on its benefits and potential side effects. The certification is granted by these regulatory agencies based on the results of these trials and other safety surveillance activities.
