Does the Food and Drug Administration require drugs to be tested on animals?

The FDA does currently require all new prescription and over-the-counter drugs to be tested on animals before they are marketed even though these tests do not make the drugs safe for humans. Unfortunately, government regulations have not kept pace with science. Modern non-animal tests are quicker, less expensive, and more accurate than the old-fashioned poisoning, blinding, and burning tests developed in the 1920s.
