In addition to the list above, it should be noted, that not only is there differing regulations on pharmaceuticals, there are also differing regulations on medical devices. And it is interesting, but there are other parts of the world that are stricter on some things than the United States. As an example, I worked at a small med device company last year that worked primarily in lubricants and ultrasound couplants. Regulations in South Korea and certain Asian countries were far stricter depending on the intended use of the product. South Korea is known for being extremely strict on things like cosmetic products, which can fall under the prevue of the FDA.
