Which organization defines the concept of safety in drug testing?

The US Food and Drug Administration (FDA) plays a crucial role in establishing the framework for drug testing, including the definition and evaluation of safety. The FDA is responsible for ensuring that new drugs entering the market are safe for consumption by the public. This involves a comprehensive review process where data from clinical trials is assessed to evaluate the safety profile of a drug.

The FDA's regulations and guidelines provide specific criteria for what constitutes safety in drug testing, including the identification of adverse effects, the monitoring of safety during clinical trials, and the requirement for rigorous reporting and analysis of safety data. This systematic approach helps protect public health and ensures that drug products meet acceptable safety standards before they can be approved for use.

While other organizations like the World Health Organization, the European Medicines Agency, and the National Institutes of Health contribute to various aspects of drug regulation and public health, the FDA is the primary authority in the United States for defining and enforcing safety guidelines in drug testing.
