Research for a new drug begins in the laboratory. Drugs undergo laboratory and animal testing to answer basic questions about safety. Drugs are tested on people to make sure they are safe and effective.
How important is FDA approval?
FDA approval is important, because it validates the need for research on how drugs work on children, not just adults. It also allows us the properly determine the appropriate dosage for children, determine the best route of administration, and test for any drug interactions.
What are the 4 stages of drug development?
Drug Development Phases
- Phase 1: Discovery and Development.
- Phase 2: Preclinical Research.
- Phase 3: Clinical Research.
- Phase 4: FDA Review.
- Phase 5: FDA Post-Market Safety Monitoring.
Does FDA approval mean it works?
FDA does not develop or test products before approving them. Instead, FDA experts review the results of laboratory, animal, and human clinical testing done by manufacturers. If FDA grants an approval, it means the agency has determined that the benefits of the product outweigh the known risks for the intended use.
