A Canadian study found the drug orlistat, which blocks fat absorption
in the intestine, was more effective in reducing obese children's body
mass index and their waistlines than placebos. The principal
investigator in the study said orlistat was the first medication shown
to be useful in obese children and that it went beyond changes in
lifestyle, diet and activity. The drug, sold as Xenical by Hoffmann-La
Roche, was given to 12- to 16-year-old children in the study.
