Of all the things that you trust every day, you want to believe your prescription medicine is safe and effective. The pharmaceutical industry says that it follows the highest standards for quality. But in November, we found out just how much could go wrong at one of the world's largest drug makers. A subsidiary of GlaxoSmithKline pleaded guilty to distributing adulterated drugs. Some of the medications were contaminated with bacteria, others were mislabeled, and some were too strong or not strong enough. It's likely Glaxo would have gotten away with it had it not been for a company insider: a tip from Cheryl Eckard set off a major federal investigation. Eckard worked in Glaxo quality control and over ten years she had risen to become a manager of global quality assurance. In 2002, Eckard was assigned to help lead a quality assurance team to evaluate one of Glaxo's most important plants, in Cidra, Puerto Rico. Nine hundred people worked there, making 20 drugs for patients in the U.S. But Eckard says that when she saw what was happening to some of the company's most popular drugs, she couldn't believe it. All the systems were broken, the facility was broken, the equipment was broken, the processes were broken. It was the worst thing I had run across in my career," she [said]. As her team continued its evaluation of the plant, Eckard says ... that powerful medications were getting mixed up.
