Publication in Federal Register Tomorrow Moves BELVIQ® (lorcaserin HCl) Closer To Launch

WOODCLIFF LAKE, N.J., May 7, 2013 /PRNewswire/ -- Eisai Inc. announced today that the U.S. Drug Enforcement Administration (DEA) has placed BELVIQ (pronounced BEL-VEEK) into Schedule IV of the Controlled Substances Act. This information is expected to be published in the Federal Register on May 8, with an effective date of June 7, 2013. Eisai will issue a public statement when BELVIQ is available in the U.S. 

BELVIQ was approved by the FDA on June 27, 2012 for chronic weight management in adults who are overweight with a comorbidity or obese.

About BELVIQ (lorcaserin HCl) Tablets

BELVIQ is believed to decrease food consumption and promote satiety by selectively activating serotonin 2C receptors in the brain. The exact mechanism of action of BELVIQ is not known. BELVIQ is a federally controlled substance (CIV) because it may be abused or lead to drug dependence.


BELVIQ is used along with a reduced-calorie diet and increased physical activity for chronic weight management in adults who have a:

  • Body mass index (BMI) of 30 kg/m2 or greater (obese), or
  • BMI of 27 kg/m2 or greater (overweight) with at least one weight-related medical condition such as high blood pressure, high cholesterol, or type 2 diabetes.

Limitations of Use:

  • The safety and effectiveness of BELVIQ in combination with prescription, over-the-counter, and herbal weight loss products is not known.
  • It is not known if BELVIQ changes the risk of heart problems or stroke, or death due to heart problems or stroke.

Important Safety Information

  • Pregnancy: Do not take BELVIQ if you are pregnant or planning to become pregnant. BELVIQ may harm your unborn baby, as weight loss offers no potential benefit to a pregnant woman.
  • Serotonin Syndrome or Neuroleptic Malignant Syndrome (NMS)-like reactions: Before using BELVIQ, tell your doctor about all the medicines you take, especially medicines that treat depression, migraines, mental problems, or the common cold. These medicines may cause serious or life-threatening side effects if taken with BELVIQ. Call your doctor right away if you experience agitation, hallucinations, confusion, or other changes in mental status; coordination problems; uncontrolled muscle spasms; muscle twitching; restlessness; racing or fast heartbeat; high or low blood pressure; sweating; fever; nausea; vomiting; diarrhea; or stiff muscles.
  • Valvular heart disease: Some people taking medicines like BELVIQ have had heart valve problems. Call your doctor right away if you experience trouble breathing; swelling of the arms, legs, ankles, or feet; dizziness, fatigue, or weakness that will not go away; or fast or irregular heartbeat. Before taking BELVIQ, tell your doctor if you have or have had heart problems.
  • Changes in attention or memory: BELVIQ may slow your thinking. You should not drive a car or operate heavy equipment until you know how BELVIQ affects you.
  • Mental problems: Taking too much BELVIQ may cause hallucinations, feeling high or in a very good mood, or feelings of standing outside of your body.
  • Depression or thoughts of suicide: Call your doctor right away if you notice any mental changes, especially sudden changes in your mood, behaviors, thoughts, or feelings, or if you have depression or thoughts of suicide.
  • Low blood sugar: Weight loss can cause low blood sugar in people taking medicines for type 2 diabetes, such as insulin or sulfonylureas. Blood sugar levels should be checked before and while taking BELVIQ. Changes to diabetes medication may be needed if low blood sugar develops.
  • Painful erections: If you have an erection lasting more than 4 hours while on BELVIQ, stop using BELVIQ and call your doctor or go to the nearest emergency room right away.
  • Slow heart beat: BELVIQ may cause your heart to beat slower.
  • Decreases in blood cell count: BELVIQ may cause your red and white blood cell count to decrease.
  • Increase in prolactin: BELVIQ may increase the amount of a hormone called prolactin. Tell your doctor if your breasts begin to make milk or a milky fluid or if you are a male and your breasts begin to increase in size.
  • Most common side effects in patients without diabetes: Headache, dizziness, fatigue, nausea, dry mouth, and constipation.
  • Most common side effects in patients with diabetes: Low blood sugar, headache, back pain, cough, and fatigue.
  • Nursing: BELVIQ should not be taken while breastfeeding.
  • Drug Interactions: Before taking BELVIQ, tell your doctor if you take medicines for depression, migraines or other medical conditions such as: triptans, medicines used to treat mood, anxiety, psychotic or thought disorders, including tricyclics, lithium, selective serotonin reuptake inhibitors, selective serotonin-norepinephrine reuptake inhibitors, monoamine oxidase inhibitors, or antipsychotics; cabergoline; linezolid (an antibiotic), tramadol, dextromethorphan (an over-the-counter (OTC) common cold/cough medicine), OTC supplements such as tryptophan or St. John's Wort, or erectile dysfunction medicines.

DevOps theory promotes a culture of continuous improvement built on collaboration, empowerment, systems thinking, and feedback loops. But how do you collaborate effectively across the traditional silos? How can you make decisions without system-wide visibility? How can you see the whole system when it is spread across teams and locations? How do you close feedback loops across teams and activities delivering complex multi-tier, cloud, container, serverless, and/or API-based services?
Today every business relies on software to drive the innovation necessary for a competitive edge in the Application Economy. This is why collaboration between development and operations, or DevOps, has become IT’s number one priority. Whether you are in Dev or Ops, understanding how to implement a DevOps strategy can deliver faster development cycles, improved software quality, reduced deployment times and overall better experiences for your customers.
In the 21st century, security on the Internet has become one of the most important issues. We hear more and more about cyber-attacks on the websites of large corporations, banks and even small businesses. When online we’re concerned not only for our own safety but also our privacy. We have to know that hackers usually start their preparation by investigating the private information of admins – the habits, interests, visited websites and so on. On the other hand, our own security is in danger bec...
The Internet of Things (IoT), in all its myriad manifestations, has great potential. Much of that potential comes from the evolving data management and analytic (DMA) technologies and processes that allow us to gain insight from all of the IoT data that can be generated and gathered. This potential may never be met as those data sets are tied to specific industry verticals and single markets, with no clear way to use IoT data and sensor analytics to fulfill the hype being given the IoT today.
Enterprises have been using both Big Data and virtualization for years. Until recently, however, most enterprises have not combined the two.

With recent technology innovations, we've seen the advantages of bare metal erode to such a degree that the enhanced flexibility and reduced costs that cl...
