Mr. Baker kept digging. Over the next five years, first in India and then in China, he uncovered fraud or deceptive practices in almost four-fifths of the drug plants he inspected. Some of the plants used hidden laboratories, secretly repeated tests and altered results to produce fake data that fundamentally misrepresented drug quality, then submitted that data to regulators.
In some instances, deceptions and other practices have contributed to generic drugs with toxic impurities, unapproved ingredients and dangerous particulates reaching American patients. Some doctors have struggled to stabilize patients who became sicker after they were switched from a brand-name to a generic, or between generic versions. A low-cost drug is not a bargain if it doesn’t work.
