Prescription weight loss pills
To lose weight, people usually resort to conservative methods of weight loss: regular physical activity and decrease in caloric intake. However, these weight loss methods are not always effective enough.
If you want to lose weight, but workouts and diets do not help, perhaps prescription weight loss pills will help obese person to achieve the desired result.
The modern pharmaceutical industry produces a large number of drugs designed to fight overweight and obesity. They all have different mechanisms of action that are aimed at elimination of particular causes that contribute to accumulation of excess body weight.
However, weight loss medications are not magic pills and ineffective if the person continues to lead a sedentary lifestyle and eat properly.
Obese Americans can buy prescription weight loss pills at retail pharmacies, the largest of which are Walgreens, CVS Pharmacy, and Walmart. Many weight loss pills are also available on online pharmacies.
According to people losing weight, one of the causes of excess weight gain is increased appetite. A man accustomed to large portions of food high in fat finds it very difficult to switch to a balanced low-calorie diet. He constantly experiences feeling of hunger and fights increased appetite all the time.
To reduce excessive appetite and boost your body's ability to weight loss, anorectic drugs are prescribed. These prescription weight loss pills belong to the most effective and promote rapid weight loss by suppressing appetite.
One of the most popular anorectics on the US market is a sympathomimetic amine Phentermine approved by the FDA in 1959. The mechanism of Phentermine action is based on stimulation of the brain centers that regulate appetite and feeling of fullness.
Phentermine effectively reduces appetite and at the same time causes rapid satiety. Advantage of Phentermine is modification of eating behavior. After treatment course with this drug, patients stop to overeat and do not depend on food any more.
In addition to anorexigenic effect, Phentermine has an ability to raise blood pressure and increase heart rate. For this reason, the drug is not recommended for patients with coronary heart disease, uncontrolled hypertension and glaucoma.
Psychostimulant Phentermine is similar to amphetamine in properties and structure. Due to high risk of mental dependence, Phentermine belongs to controlled substances. For this reason, this anorectic is sold at retail pharmacy chains by prescription.
If a person wants to buy weight loss pills Phentermine without prescription, he can order them on online pharmacy. However, before to start using the drug for weight loss, it is necessary to carefully read the package insert.
On the world pharmaceutical market, Phentermine is supplied under the trade names Adipex, Lomaira, Suprenza, Duromine, and Ionamin.
Besides these prescription weight loss pills, a new drug Qsymia for weight loss containing combination of anorectic Phentermine and anticonvulsant Topiramate was approved in 2012.
Like other Phentermine-containing drugs, Qsymia capsules are intended for use in conjunction with diet and adequate physical activity.
Since the problem of overweight and obesity annually becomes more and more urgent, scientists continue to create new effective drugs for weight loss.
In 2012, the FDA approved a new drug Lorcaserin for weight loss under the trade name Belviq. The mechanism of Lorcaserin action is based on activation of type 2 serotonin receptor. The drug blocks feeling of hunger and promotes rapid saturation even in small amount of food consumed.
Since Lorcaserin affects serotonin receptors, the drug should not be taken simultaneously with selective serotonin reuptake inhibitors used to treat depression.
Clinical studies have shown that Lorcaserin helps the patient to lose an average of 5% of body weight that many obese people consider insignificant result.
However, experts pointed out that Lorcaserin (Belviq) does not cause serious side effects, unlike other prescription weight loss pills. Side effects of a new drug include headache, depression, attention and memory disorders.
Herewith, it should be noted that not all people experience side effects.
Yet, before to buy weight loss pills Belviq online without prescription, consult a specialist since the drug has certain contraindications for use.
Orlistat is significantly different from other drugs for weight loss. In the US and Europe, Orlistat is supplied under the brand names Xenical (prescription weight loss pills) and Alli (OTC weight loss drug).
The drug has a unique mechanism of action, which is based on the ability of active substance Orlistat to block absorption of fats coming with food.
Good tolerability of Orlistat is explained by peripheral mechanism of action. Orlistat acts exclusively in the intestine, almost is not absorbed into the systemic circulation and unlike other drugs for weight loss, does not affect the CNS function.
Orlistat does not cause neither physical nor psychological dependence nor addiction, so the drug is used for a long time.
In general, side effects of Orlistat are transient and involve the gastrointestinal tract. Common adverse reactions of the drug include bloating, frequent urge to defecate, and oily stool.
Today Orlistat is one of the most popular and safest prescription weight loss pills, which you can buy both at the largest retail pharmacies and on online pharmacies.
