A new drug 'Qnexa' which is a
combination of 2 existing slimming drugs- phentermine and topiramate can help
women drop two dress sizes in a year has been developed by scientists at the
Duke University Medical Centre in North Carolina. Phentermine is an amphetamine-based
slimming drug and topiramate is an epilepsy drug linked to weight loss.
It has been reported that Qnexa has health benefits, including reduction of the blood pressure and levels of dangerous blood fats and sugar. This new drug has twice the slimming power of the existing obesity treatment prescribed by GP's (Tab. Orlistat).
During the study 2,500 overweight and obese Americans who were part of the study were either given variable doses of Qnexa once a day or a placebo pill. This regime was carried on for a year. It was found that subjects who were given high doses of Qnexa lost 10.2kg (22pounds) weight with certain lifestyle interventions. Up to 21% of people who were given Qnexa experienced side-effects including tingling, dizziness and constipation. Some even reported of anxiety and depression.
