FDA 自己说， Generic Medicines 的效力，安全性，质量是有严格的标准的， 可以说是原版的复制品。。。

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
