Every year, an estimated 26 million animals are used for scientific and commercial testing. These animals are used to help develop numerous different things such as medical treatments, safety checks of products that will be used by humans, figuring out toxicity of medications, and many more biomedical, health care, and commercial uses (Hajar 2011). Animal testing dates as far back as ancient Greek times, physician-scientists like Aristotle and Erasistratus, had performed experiments on living animals, as did Ibn Zuhr, a physician in the twelfth century (Hajar 2011). Proponents of animal testing believe there are no alternative methods for research. Animal testing has enabled lifesaving treatments for humans and animals and there are strict regulations to prevent mistreatment of animals in laboratories. Opponents feel that animal testing is cruel and inhumane and believe that there are other alternative methods to testing. They also believe the biological and physiological differences between humans and animals vary too much and often yield irrelevant results. While testing is required for medical advancements alternative methods of testing like in vitro, cell culture, genomics, and proteomics should be more widely…show more content…
The drug tacrolimus, which is used to lower organ transplant rejections, was almost completely dismissed because of animal test results. Animals simply make poor models for human because of the vast anatomic, metabolic and cellular differences (Akhtar 2013). While completely replacing animal testing doesn’t seem likely, other options for testing are available. In vitro tests are based in human cell and tissues cultures. Episkin can be used to test the irritants on skin versus an animals, stem-cell and genetic testing, micro dosing, and computer models and simulations all provide a step in a new directions of effective medical testing (Watts
