The U.S. Food and Drug Administration has approved the drug Belviq (lorcaserin hydrochloride), in addition to calorie control and exercise, for helping weight reduction in some overweight adults.
In a news release the FDA has announced its approval of the weight loss pill Belviq to treat some overweight or obese adults as an addition to a reduced-calorie diet and exercise. The research results show that in comparison with a placebo, after one year’s treatment with Belviq over a 3% weight loss can occur.
According to the news release, the drug may be prescribed to adults “with a body mass index (BMI) of 30 or greater (obese), or adults with a BMI of 27 or greater (overweight) and who have at least one weight-related condition such as high blood pressure (hypertension), type 2 diabetes, or high cholesterol (dyslipidemia).”
Janet Woodcock, M.D., director of the FDA’s Center for Drug Evaluation and Research says that the drug provides an option for treatment of overweight and obese adults with comorbid health issues if used responsibly in combination with a healthy lifestyle and diet.
The drug Belviq works by activating the serotonin 2C receptor in the brain which is thought to reduce a person’s desire to over eat.
