SUNDAY, Sept. 7 (HealthDay News) -- A new once-a-week formulation of the injectable diabetes drug Byetta controls blood sugar even better than the older twice-a-day formulation, researchers report.
"Besides obvious improved ease of use, [the new formulation] provided the remarkable advantage of both improved efficacy on glucose control and good gastrointestinal tolerability," said Dr. Andre Scheen of the University of Liege in Belgium, in a commentary accompanying the study's publication online Sunday in The Lancet.

The study, led by Dr. Daniel Drucker of Mount Sinai Hospital and the University of Toronto, Canada, is also slated for presentation Sunday at The European Association for the Study of Diabetes meeting, in Rome.
The findings, while encouraging, come on the heels of less-heartening news about Byetta (exenatide). On Aug. 26, the drug's makers, Eli Lilly and Amylin Pharmaceuticals Inc., reported the pancreatitis-linked deaths of four people who'd been taking the medication. That news came a week after the U.S. Food and Drug Administration said that two Byetta users had died of acute pancreatitis, a condition that can cause nausea, vomiting and abdominal pain.
While Byetta use has not been confirmed as a causative factor in these deaths, the FDA has noted an association between Byetta use and pancreatitis, and on Aug. 18 announced it was working on stronger labeling for the injected drug, which has been used by more than 700,000 people since being approved in June 2005.
The new study involved 259 patients with type 2 diabetes who received 30-week courses of either 2 milligrams of long-acting release Byetta given once weekly, or 10 microgram doses given twice a day. Researchers monitored blood sugar control via levels of hemoglobin A1C in the blood (HbA1c), which averaged 8.3 percent at the start of the study.
