FDA approves new wight loss drug Belviq

What is Belviq?

Belviq weight loss

The Food and Drug Administration (FDA) has approved Arena Pharmaceutical’s anti-obesity pill Belviq, the first new prescription drug for long-term weight loss to enter the U.S. market in over a decade. The new drug, developed by Arena Pharmaceuticals of San Diego, has been known as lorcaserin and will be sold under the name Belviq by Eisai Inc., the American branch of the Japanese pharmaceutical company.

The FDA cleared the pill Wednesday for adults who are obese or are overweight with at least one medical complication, such as diabetes or high cholesterol. The drug should be used in combination with a healthy diet and exercise.

The drug is approved for adults with a body mass index (BMI) of 30 or over – which indicates obesity – or with a BMI of 27 or greater (overweight) who have at least one weight-related health problem such as high blood pressure, Type 2 diabetes or high cholesterol. It is manufactured by Switzerland-based Arena Pharmaceuticals.

In clinical trials people who took Belviq were twice as likely to lose 5 percent or more of their weight than people who took a placebo. The drug was also linked to improvements in blood pressure, cholesterol and blood sugar levels.

“It’s about time that they approved a new drug,” said Dr. Judith Stern, a professor of nutrition at the University of California at Davis. “Obesity drugs should be on the fast track.”

“For the half of America that seriously needs some help in reducing energy intake, this has some promise,” said Dr. Barry Popkin, a professor of nutrition at the University of North Carolina at Chapel Hill. Other experts have expressed more caution.

However, Belviq won’t immediately be available for sale. The drug has to go through a four-to-six month process at the Drug Enforcement Administration for a scheduling classification used for drugs that have a likelihood or potential of being abused. Once that process is over, Eisai will announce pricing and when the drug will be available.


What is Belviq?

Belviq is a prescription medicine that may help some obese adults or overweight adults who also have weight related medical problems lose weight and keep the weight off.

Belviq should be used with a reduced calorie diet and increased physical activity.

FDA approval

In approving Belviq (formerly known as lorcaserin), the U.S. Food and Drug Administration followed the recommendation of an outside panel of experts who voted 18-4 with one abstention last month to support the weight-loss drug while still voicing concerns about lackluster efficacy and lingering safety questions.

FDA is expected to make its next approval decision for a weight-loss drug on July 17 when it weighs in on Vivus Qnexa. Orexigen Therapeutics will seek approval for its weight-loss drug Contrave pending positive results from an ongoing heart-safety study.

Arena said it was not clear yet when the drug would be available to patients and what it would cost. Because the F.D.A. deemed that there was some potential for the drug to be abused, the Drug Enforcement Administration must now decide what controls to place on prescribers, a process that Arena said could take four to six months.


What are the ingredients in Belviq?

Active Ingredient: lorcaserin hydrochloride

Inactive Ingredients: silicified microcrystalline cellulose; hydroxypropyl cellulose NF; croscarmellose sodium NF; colloidal silicon dioxide NF; polyvinyl alcohol USP; polyethylene glycol NF; titanium dioxide USP; talc USP; FD&C Blue #2 aluminum lake; and magnesium stearate NF.

Other FDA weight loss drugs

The last anti-obesity drug approved in the United States was Xenical (Orlistat) by Roche in 1999.

Sold over the counter as Alli by GlaxoSmithKline, it works by preventing the body from absorbing fat, though its tendency to cause gastrointestinal side effects such as oily, loose stools have curbed its popularity among patients.

Shares of Vivus Inc. climbed Wednesday after regulators approved a rival obesity drug, raising hopes that Vivus’ drug Qnexa will be cleared in July.

    Can you please send me an e-mail when Belviq becomes available to purchase? My doctor already told me he will not prescribe this to me is there any reason he would rather I stay obese after dieting for years rather than prescribe me this newly released drug? Should I be concerned?

    I am in Fort Worth, Texas. Are there any doctors in this area who will prescribe belviq? I would like to be a trial patient if I can’t find someone in Texas who will prescribe the drug.
