3 Recommended By The FDA To Treat Obesity Drugs
The Food and Drug Administration (FDA) warns of the many drugs circulating on the Internet and in gyms that promise miraculous weight loss results. However, these drugs can have side effects so it is better than the person not treat yourself but contact your doctor.
This is the latest diet drug, developed by Arena Pharmaceuticals. Belviq is a drug that can reduce an average of 5.8% of body weight in one year and best of all is that their long-term effects are quite durable, as has been confirmed in clinical trials that were submitted for approval medication.
Its mechanism of action is very simple: Belviq activates the serotonin 2C in the brain, a receptor that helps block hunger signals to the central nervous system. In this way, the person need not eat much to feel satiated because the hunger signal is interrupted.
Of course, like any medicine can also cause unwanted effects, such as migraine, depression and memory lapses, but these are generally rare. However, it should be clarified that the FDA recommended against its use in pregnant or during lactation, to avoid any complications. Now it is studying whether it can increase the risk of heart attacks and strokes.
Qsymia is another antiobesity drugs approved by the FDA. The drug is manufactured by Vivus Inc. and is designed for adults with body mass index equal to or greater than 30; ie for obese people. While also it is used in those who are overweight and associated complications such as hypertension, high cholesterol and type II diabetes.
Actually, Qsymia is the result of the action of two substances: phentermine, which helps suppress appetite, and topiramate, an anticonvulsant long-acting that generates the feeling of satiety. By consuming the drug three times a day, at mealtimes, the person may eat less and feel satisfied and accomplished lose weight.
Studies have shown that the higher the dose of Qsymia, the greater the weight loss is achieved, on average 8.9% of the total weight. However, this drug should be consumed with caution because their long-term side effects are not known with certainty. In fact, the FDA suggests that is not used during pregnancy because it can cause damage to the fetus.
Orlistat was the first authorized in Spain and Europe for inhibiting fat absorption drug. Currently its trademark is Xenical, but can also be purchased under the name Alli, a special type of pills containing half the concentration of Orlistat and that can be bought without a prescription.
Its mechanism of action is very simple because it works by preventing the absorption of about 30% of ingested fats, which are eliminated through feces. This drug is taken three times a day and can eliminate much of the calories we consume daily, so it is recommended for those with a body mass index greater than 27.
Its biggest drawback is that those who are under treatment generally have an oily diarrhea that can not be controlled and it is very unpleasant. However, it is known that reducing fat intake, this effect can be kept under control. It is also common to decrease the absorption of some fat-soluble vitamins such as vitamin D, so it is necessary to accompany the Orlistat with vitamin supplements.
