Weekly diabetes jab hopes raised
It may be possible to replace twice a day jabs to control type 2 diabetes with a shot given just once a week, research suggests.
Scientists found a new formulation of the drug exenatide gave better control of blood sugar levels than the current twice-daily regimen.
But experts said research was needed to confirm the findings.
Over 30 weeks 259 patients were either given a shot of a long-acting form of exenatide once a week, or had the traditional twice-a-day jabs.
Lower levels of this chemical are an indication that blood sugar levels are being controlled effectively.
Patients who were given the once-a-week jab registered a bigger average drop in HbA1c levels than those who had the twice daily jabs. A higher proportion of them also hit the target level for HbA1c during the study.
Exenatide works by increasing secretion of insulin - the hormone which breaks down sugar - following a meal.
It also suppresses release of another hormone glucagon, which helps stop the liver from overproducing sugar when it is unneeded.
The authors conclude: "Exenatide once weekly resulted in significantly greater improvements in glycaemic control than exenatide given twice a day, with no increased risk of hypoglycemia and similar reductions in bodyweight."
Hypoglycemia is a condition caused by blood sugar levels being too low. It produces a range of symptoms, including palpitations, shaking and sweatiness.
Dr Iain Frame, of the charity Diabetes UK, said: "There is not much detail provided in the report of this preliminary study but the results appear to be promising.
According to Diabetes UK, more than 2.3m in the UK have type 2 diabetes, with many cases thought to be undiagnosed.
Details of the study were presented to a European Association for the Study of Diabetes conference in Rome.
