FDA 自己說， Generic Medicines 的效力，安全性，質量是有嚴格的標準的， 可以說是原版的複製品。。。

Generic drugs are important options that allow greater access to health care for all Americans. They are copies of brand-name drugs and are the same as those brand name drugs in dosage form, safety, strength, route of administration, quality, performance characteristics and intended use. － From FDA
