A DIET pill billed as helping women drop two dress sizes in six months will be released here.
Denmark company Neurosearch expects the drug Tesofensine to be on the market here in three years.
It is claimed the drug can help people lose, on average, 10kg.
But side effects include nausea, diarrhoea, constipation, insomnia and an increased heart rate.
The drug affects the part of the brain controlling appetite, making people feel full soon after starting a meal.
More than 200 people participated in trials by Prof Arne Astrup, who is president of the International Association for the Study of Obesity and has shares in Neurosearch.
"You could easily come up to 20 per cent weight loss, which could offer an alternative to the surgical treatment of obesity," Prof Astrup said.
Dr Greg Steinberg, from St Vincent's Institute of Medical Research, warned it was nothing more than a "quick fix".
Dr Steinberg compared taking the drug with going on a crash diet, saying people would regain weight unless they changed their lifestyles.
