UPDATE 2-U.S. FDA warns on newer class of type 2 diabetes drugs

May 15 (Reuters) - The U.S. Food and Drug Administration on Friday warned that a widely used newer class of type 2 diabetes drugs sold by AstraZeneca, Johnson & Johnson and Eli Lilly in partnership with Boehringer Ingleheim may cause dangerously high levels of blood acids that could require hospitalization.
The oral drugs belong to a class known as SGLT2 inhibitors that work by causing blood sugar to be secreted in the urine. They include AstraZeneca's Farxiga (dapagliflozin), J&J's Invokana (canagliflozin) and Jardiance (embagliflozin) from Lilly and Boehringer.
The FDA, in a warning on its website, said the medicines may lead to ketoacidosis, a serious condition where the body produces high levels of blood acids called ketones.
The FDA said its Adverse Event Reporting System database identified 20 cases of acidosis reported as diabetic ketoacidosis, ketoacidosis, or ketosis in patients treated with SGLT2 inhibitors between March 2013 to June 6, 2014. It said all the affected patients required emergency room visits or hospitalization to treat the condition.
