WHY ANIMAL TESTING IS NECESSARY?

Researchers use animal testing in preclinical research in order to determine the overall safety of many new drugs, treatments, or other products. 

The animal subjects trial these new medicines and treatments before companies can release them for human use. Basically, it’s necessary to test the effectiveness of these new drugs, treatments, or products on living creatures.  Therefore, researchers use animal models before moving forward with human use.

In order to determine the overall impact of a drug, treatment, or product researchers carefully choose which animal subject they will use.  Furthermore, medical devices or drug testing can take years to complete. It’s truly essential to make the right animal testing choice.  Therefore, the animal test subject has to meet several unique requirements specific to each test.

HOW DO RESEARCHERS CHOOSE ANIMALS FOR TESTING?

Anytime preclinical research involves the testing of new drugs or products, research teams consider a number of different animal subjects. It’s important for researchers to determine which animal models will work best for each particular treatment or product. If they make the wrong choice testing results may not be correct. Then testing may have to start all over again.  In the worst case, new products or drugs could hit the market and harm the humans who use them.

The decision of which animal to use in a new preclinical research test is complex and includes different factors. Some examples include the type of drug being tested, the size of the animal models, and the characteristics of the animal models.

For example, animal subjects are common test subjects for new pacemakers (devices to keep your heart beating correctly). Although researchers frequently choose mice when it comes to preclinical research, mice are a poor fit for this type of test. A pacemaker device must attach to the animal, so smaller animal models like mice simply won’t work. A larger animal testing subject is a better fit. Thus, finding the appropriate animal model for upcoming preclinical research essential for the overall success of a research study.

Common Animal Test Subjects

Other animals researchers use for preclinical research studies include rabbits, pigs, sheep, guinea pigs, birds, fish, and ferrets.

Dogs, cats, and non-human primates have many characteristics that make them similar to humans. However, researchers choose these animal models for less than 1% of preclinical research studies.
