The health and welfare of human beings is the top priority of all governmental and regulatory organizations around the world. That is why pharmaceutical companies must test their experimental medicines in animals before they are allowed to test them in humans.
The Declaration of Helsinki of the World Medical Association says that it is unethical to give experimental treatments to humans that have not been tested first in laboratory animals. The Declaration is the foundation of many national laws regarding medical research. Healthcare professionals from around the world have signed it.
Every pharmaceutical company is required to submit animal study results for new medicines before starting any studies in humans.
Regulatory authorities in countries around the world require all pharmaceutical medicines to be proven safe and effective. In order to do so, these regulations require every pharmaceutical company to submit animal study results for new medicines before starting any tests in humans. The regulations also require companies to carry out additional longer-term toxicity studies in animals to get approval for a new medicine.
This type of regulation is not unique to the pharmaceutical industry. Legislation has been passed and implemented at national and international levels for a range of substances that could be harmful to animals, humans or the environment.
