Orlistat (Xenical) in combination with diet and lifestyle changes significantly prevents obese patients from developing type 2 diabetes, say researchers involved in this 4-year study presented at the 9th International Congress on Obesity, Sao Paulo, Brazil. They add that this is the first time a weight loss drug has been shown to prevent or delay the onset of type 2 diabetes in an at-risk population.

The investigational inhaled insulin product (Exubera) could prove a boon to patients with diabetes, cutting or eliminating the need for injections. So indicate findings from a phase III trial presented at the annual meeting of the American Association of Clinical Endocrinologists (AACE). For patients with type 1 diabetes, a regimen of inhaled insulin before meals and one injection at night could control blood glucose as well as or possibly better than injections alone. These results add to some phase III data presented last June that showed a small but significant number of patients with type 2 diabetes reached recommended blood glucose levels at 6 months.

Therapy starting with the angiotensin receptor blocker (ARB) losartansignificantly reduced the risk of cardiovascular outcomes and new-onsetdiabetes compared with a beta blocker in older high-risk hypertensive patients,said Björn Dahlöf, MD. The improved outcomes with losartan occurredeven after adjusting for small differences in blood pressure reduction betweenthe two study drugs.

For the first time, a large clinical trial has shown that a medication can help prevent type 2 diabetes in high-risk individuals. At the same time, drug therapy emerged as a less effective preventive strategy than fairly modest diet and exercise changes.
