Avandia® Aids Recovery of Insulin-Secreting Cells

Posted: Wednesday, December 01, 2004

The anti-diabetes drug Avandia not only improves the body's response to insulin but also helps insulin-producing cells in the pancreas recover their function.

"This is the first study to demonstrate an improvement in the first phase of the insulin secretory response to glucose in subjects with long-standing type 2 diabetes receiving oral pharmacological therapy," the researchers note.

Dr. David Bell from The University of Alabama at Birmingham School of Medicine, in an interview stated that, Avandia, known generically as rosiglitazone, belongs to a class of drugs called thiazolidines or TZDs. The fact that these drugs apparently rejuvenate pancreatic beta cells "makes TZDs unique among diabetic therapies."

Bell and Dr. Fernando Ovalle compared Avandia with insulin treatment in a group of subjects with of type 2 diabetes.

The initial insulin response to glucose increased significantly in the Avandia group, but not in the insulin-treated group, the duo reports in the medical journal Diabetes Care.

The team thinks the results should lead to a change in the standard approach to treating type 2 diabetes.

"Instead of being initiated after other oral agents have failed, thiazolidines should be initiated at the earliest possible time," Bell said. "TZDs should be started when there is the maximal beta cell function — that is, when diabetes is diagnosed."
