From the article:
Beginning with the Bush administration, the Food and Drug Administration has stepped into suits on the side of defendant pharmaceutical companies, arguing that federal regulation of drugs pre-empts state suits.
The article also reminds us that thousands of people die each year from medical errors. Lawsuits like the one Quaid is filing against Baxter Healthcare Inc. (the maker of the heparin) are one way of holding those who make these errors accountable.
