Some good news for diabetics, but perhaps not for the maker of a new diabetes drug.
Researcher have concluded that older and cheaper diabetes drugs are as safe and effective as newer ones.
A Johns Hopkins University researcher who led the review says a drug called metformin, which is available generically for about 100 dollars a year is the one that "looks to be the safest."
Consumer Reports has published a consumer guide of the results, which were published by the Annals of Internal Medicine.
Besides metformin, which is sold as Glucophage, the other drugs rated as best bets are the ones sold as Amaryl and Glucotrol.
The findings may further hurt sales of Avandia, a blockbuster pill that's recently been linked to heart problems.
