Avandia, marketed by GlaxoSmithKline, has been a popular drug prescribed to diabetics in the U.S.  Because of their disease, diabetics are at high risk of heart attack and heart failure – in fact, two-thirds of people with diabetes die of heart problems.   Diabetics have been prescribed Avandia largely to lessen their chance of heart attack and heart failure. However, Avandia has been found to increase the risk of heart disease in patients who use it for a long period of time.  Avandia has been investigated by the Food and Drug Administration since 2007, but it is still available in the U.S. market.  An estimated 13,000 Avandia law suits have been brought against the company since 2007.
