The question – “How to get rid of excess weight?” worries many people. Extra pounds badly affect not only the person’s figure, but also his health. People usually start weight loss process with traditional methods – a variety of diets and exercise.
However, when non-drug methods do not bring the desired result, patients seek the doctor’s help. Today, you can find a wide range of different drugs for weight loss on the shelves of pharmacies.
Alli and Phentermine anti-obesity drugs are among the most popular drugs for obesity therapy. Both these drugs are recommended for the treatment of overweight in conjunction with a low calorie diet and exercise. Despite the fact that Phentermine and Alli are used with the same purpose, they have a number of differences.
One of the main differences between these weight loss drugs is the fact that Phentermine is a prescription drug, and Alli was approved by the FDA as a non-prescription weight loss aid.
Another significant difference is the presence of different active ingredients used in these slimming medications.
Alli contains Orlistat, and Phentermine – Phentermine Hydrochloride. At its core, these are two completely different substances with different mechanisms of action.
Phentermine Hydrochloride is similar to amphetamine in its chemical structure and has anorexigenic effect. Affecting the certain centers of the brain, Phentermine suppresses appetite and promotes rapid saturation. Herewith, the person feels full of energy and strength, as well as mental performance is increased.
Orlistat is a specific inhibitor of gastrointestinal lipases. Due to its action, the splitting of dietary fats is violated and their absorption from the gastrointestinal tract is reduced. Orlistat is practically not absorbed from the gastrointestinal tract and has no resorptive action.
As a result, the amphetamine-like drug – Phentermine is an appetite suppressant, gives a person energy and a positive mood for the whole day. Alli is a hypolipidemic agent, which prevents the breakdown of fats, but does not suppress appetite.
Dosage form of Phentermine is peroral capsules and tablets of different dosages (15 mg, 30 mg, and 37.5mg), but Alli is available in capsules of 60mg. The recommended daily dose of Phentermine is 37.5 mg per day. Experts recommend taking Phentermine psychostimulant in the morning and do not take it in the evening because it may cause insomnia.
An Alli capsule is taken orally during each main meal (usually no more than 3 capsules per day). If the food is low in fat, the intake of slimming caps can be skipped.
Phentermine is used as a short-term treatment of obesity, but Alli can be taken as much as necessary to achieve the desired result.
