Drugs major GlaxoSmithKline's important Avandia diabetes treatment could be prohibited on both sides of the Atlantic, as controllers individually prepare to provide their judgments on its future.

GSK's one-time largest retailing drug will be assessed by the US Food and Drug Administration on Tuesday and Wednesday next week.

The subsequent week, in a meeting beginning on July 19, the European Medicines Agency (EMA) will assess the medicine's vending in Europe that can result in it being cancelled, suspended or limited - or come to a decision that its business is normal.

Avandia has been plagued by security fears, as examination by the Cleveland Clinic in 2007 recommended that it boosted the possibility of heart attacks.

Tracking a new research that indicated a connection between Avandia and heart conditions, the FDA will ask its advisory group to find out whether the drug should be forbidden, in total, remain accessible as it is, put through new cautions, or be issued to a small number of patients.

Both regulators have been prompted to action by research that was made public two months back by David Graham from the FDA's Office of Surveillance and Epidemiology, and Steven Nissen, chief of cardiology at the Cleveland Clinic in Ohio.
