What You Should Know
2/2/2011 UPDATE: Today, the FDA rejected Orexigen Therapeutics Inc.’s Contrave pill, citing fears that the pill may increase heart risk. The FDA has not approved a new weight loss medication in ten years. The agency says it will evaluate Contrave again after Orexigen undertakes a costly new study examining possible links to heart risk. A spokesman for Contrave said that the company is evaluating next steps and deciding whether they will go through with the expensive study. Sorry, bad news for everyone who was looking to try this promising new drug.
12/9/2010 UPDATE: Today, the Endocrine and Metabolic Drugs Advisory Committee, a division of the FDA, has voted to recommend Contrave as a weight loss aid. However, the FDA still has to give the drug final approval before it can be distributed by physicians. The FDA takes sub-panel decisions such as this into consideration before approving any pharmaceutical drug. Like, the FDA will decide on approving Contrave for weight loss in January, 2011. However, the panel also recommends additional cardiovascular studies of patients prior to beginning sales based on case study findings, indicating that this product still may not be suitable for those with heart conditions. We will continue to update our review as more information becomes available.
Contrave is still in the testing stages, but it seems to offer great promise as a medication that will actually reduce the risk factors associated with obesity. Currently, this drug is in its third stage of clinical trials to assess the “safety, tolerability and efficacy”, according to the company website. The company that is responsible for Contrave is Orexigen Therapeuticals, a biopharmaceutical company that is focused on creating drugs that treat central nervous system disorders, including obesity. Current studies are showing that Contrave can effectively reduce metabolic syndrome in many patients. Metabolic syndrome is a combination of risk factors that may increase the incidence of obesity, which can also increase the risk of heart disease and diabetes. This medication takes a whole new approach to weight loss, by focusing on neurological causes of obesity rather than suppressing appetite or altering metabolic function.
List of Ingredients
The two main ingredients that are being studied in the Contrave formula include Naltrexone and Bupropion. Naltrexone has been used in the United States to treat opioid addiction since 1984, and in 1995 it began to be used to treat alcoholism as well. This drug inhibits the reinforcement of addictive substances by blocking opioid receptors to the brain, according to the Orexigen website. Naltrexone has also been shown to alter the taste of foods in numerous clinical studies.
Bupropion has been used to treat depression since 1985, and in 1997 trials were begun that experimented with the use of Bupropion as an aid to help quit smoking. This drug appears to be effective at suppressing appetite and increasing energy levels, and is the most prescribed antidepressant in the United States at the time of this review. One side effect that has been noted with Bupropion is weight loss; an attractive side effect for many indeed.
Since this medication is still in the clinical trial stage, there are few product features to report. It is suspected that this medication will only be available by prescription, since it contains potent ingredients with potentially dangerous side effects. There is no pricing or customer testimonials at this time; however, ample clinical data is provided on the Orexigen website, and this info is comprehensive and professionally displayed.

Contrave is worth keeping an eye out for, since the initial clinical studies have been promising and plenty of research is being conducted on the product. However, Contrave will not be the right choice for everyone, due to the possible side effects and medication interactions that may occur. Also, it definitely appears that Contrave will be prescription only, and will most likely be used to treat clinical obesity. It is important to talk to your doctor about whether Contrave would be a good choice for you.
