Study Notes
Safety Testing Methodology
- Rigorous scientific methodology used in safety testing involves a hierarchical approach, starting with in vitro and in silico methods, followed by animal testing, and finally, human clinical trials.
Animal Testing
- Two or more species are used in safety testing to ensure that the results are not specific to a single species and to increase the reliability of the data.
- Researchers are tasked with achieving a reduction in the number of animals used, refinement of the testing procedures to minimize animal suffering, and replacement of animals with alternative models whenever possible.
Alternatives to Animal Models
- Alternatives to the use of animal models mentioned in the text include in vitro methods, such as cell cultures and tissue engineering, and in silico methods, such as computer simulations and modeling.
Human Research Participants
- Human research participants are recruited for trials once the safety and efficacy of a substance or product have been established in animal testing and other preclinical studies.
Test your knowledge on medical advances made using animal research models, ethical concerns about using animals in research, alternatives to animal models, and products produced using transgenic animals as bioreactors.
