I quoted doctors who questioned whether generics really were bioequivalent to the brand.

我引用了质疑仿制药是否真的与品牌生物等效的医生的话。

As a result, some American patients have gotten generic drugs with toxic impurities, unapproved ingredients, dangerous particulates or that are not bioequivalent.

结果， 一些美国患者得到的仿制药含有有毒杂质、 未经批准的成分、危险微粒或不具有生物等效性。

But my biggest assumption was based on the FDA's reassurance that properly regulated generic drugs are not only safe and effective, but bioequivalent, interchangeable with the brand and with one another.

但我最大的假设是基于 FDA 的保证，即适当监管的仿制药不仅安全有效，而且具有生物等效性，可以与品牌互换。
