Amiodarone CasesAnnotate this Case
Amiodarone was developed in the 1960s for the treatment of angina and was released in other countries. Amiodarone is associated with side effects, including pulmonary fibrosis, blindness, thyroid cancer, and death. In the 1970s, U.S. physicians began obtaining amiodarone from other countries for use in patients with life-threatening ventricular fibrillation or ventricular tachycardia who did not respond to other drugs. In 1985, the FDA approved Wyeth’s formulation of amiodarone, Cordarone, as a drug of last resort for patients suffering from recurring life-threatening ventricular fibrillation and ventricular tachycardia. The FDA’s “special needs” approval issued without randomized clinical trials. In 1989, the FDA described Wyeth’s promotional activities as promoting an unapproved use of the drug. In 1992, the FDA objected to promotional labeling pieces for Cordarone. Other manufacturers developed generic amiodarone, which has been available since 1998.
Consolidated lawsuits alleged that plaintiffs suffered unnecessary, serious side effects when they took amiodarone, as prescribed by their doctors, for off-label use to treat atrial fibrillation, a more common, less serious, condition than ventricular fibrillation. The FDA never approved amiodarone for the treatment of atrial fibrillation, even on a special-needs basis. The court of appeal affirmed the dismissal of the lawsuits. The claims are preempted as attempts to privately enforce the Federal Food, Drug, and Cosmetic Act, 21 U.S.C. 301, regulations governing medication guides and labeling and have no independent basis in state law. The court also rejected fraud claims under California’s unfair competition law and Consumers Legal Remedy Act.
