The lawyers at Saiontz & Kirk are no longer investigating potential Avandia lawsuits for users throughout the United States.

Avandia (generic rosiglitazone) is an oral antidiabetic which is part of a class of drugs known as thiazolidinediones (TZDs). The medication increases the body’s sensitivity to insulin and aids in the management of blood sugar, which makes it useful to treat Type 2 diabetes.

Prior to consumers and the medical community discovering the potential Avandia risks, more than 6 million people worldwide received the diabetes drug, and GlaxoSmithKline generated $2.2 billion in sales per year in the United States.

On May 21, 2007, an Avandia study was released by the New England Journal of Medicine which reported that users of the diabetes medication could face a significantly increased risk of heart attacks and cardiovascular death.

Researchers reviewed data from 42 different clinical trials involving nearly 28,000 people, and found that those who used Avandia had a 43% increase in the risk of suffering a heart attack and a 64% increase in the risk of a heart related death when compared to those taking another drug or a placebo.

GlaxoSmithKline, PLC had the same data used by the independent researchers for over a year before the study was released. They have acknowledged that their own analysis of the data showed a 30% increased rate of heart attacks, yet they failed to promptly warn consumers or the medical community. Their failure to provide complete information about the risk of heart attacks, heart disease and death prevented those taking Avandia from making an informed decision about whether the benefits provided by the medication outweigh the danger of Avandia side effects.

In December 2007, additional research confirmed that users of Avandia may face an increased risk of osteoporosis and bone fractures. Side effects of the drug increase bone resorption and decrease bone formation, which could lead to weak and brittle bones.

In October 2008, the consumer advocacy group Public Citizen filed a petition requesting an Avandia recall. In their petition they pointed to an additional health concern involving the potential for Avandia liver failure. They identified at least 14 cases of liver failure associated with the use of Avandia, and 12 of the cases resulted in death.

While the drug was never recalled, the FDA restricted access to Avandia from September 2010 until those restrictions were lifted in December 2015. Much stronger warnings are now provided and the diabetes medication has been largely abandoned by the medical community.

GlaxoSmithKline, PLC placed their desire for profits above the safety of the consumer. As a result, millions of dollars in financial compensation were paid through Avandia class action lawsuits and individual injury claims.
