Diabetes Drug Promts Weight Reduction

   Patients receiving liraglutide, which contains a satiety hormone, were twice as likely to lose significant amounts of weight as those on orlistat.

  Not only does the drug appear to curb hunger, it also reduces type 2 diabetes risk factors, the Lancet study found.

  The study author is a paid consultant of the company which produces the drug.

  There are limitations: the drug must be injected every day as it would otherwise be broken down in the gut, and it is expensive - £500 for six months of treatment.

  Further studies are needed to establish the longer term risk-benefit ratio as this trial on 564 patients ran for just 20 weeks.

  Over this period, three groups of patients in 19 hospitals were put on a diet reduced by 500 calories a day and asked to exercise.

  One set received a placebo, the second orlistat - available by prescription as Xenical - and a third liraglutide, also known as Victoza.

  Over the 20 weeks, more than three quarters of those on 3mg of liraglutide lost more than 5% weight, compared with 44% with 120mg of orlistat and 30% with a placebo.

  This on average translated as more than a stone in weight.
