Hi, I would like to know if there are pills for weight loss, which are the most effective and where to buy them.
The term tablets refers to a very specific pharmaceutical form, intended to dissolve slowly in the mouth to convey the slimming active ingredient inside the body.
First of all, if we want to talk about pills for weight loss, it is necessary to make a distinction between drugs and supplements. In the first case, the slimming tablets can only be purchased in pharmacies, generally upon presentation of a medical prescription; in the second, on the other hand, the tablets for weight loss are at the mercy of everyone, in supplement stores, in foodstuffs, herbalists, on the internet and in pharmacies themselves.
Currently there are only two drugs approved for use for weight loss: sibutramine tablets and orlistat tablets.
Sibutramine stimulates the sense of satiety by reducing the consumption of food; it also increases thermogenesis with action mechanisms similar to those of ephedrine, an active ingredient of natural origin useful for weight loss but no longer marketable as a supplement. The main side effects are of a cardiovascular nature (tachycardia, palpitations, hypertension), such as to make these tablets contraindicated in the presence of heart and cardiovascular problems (high blood pressure, atherosclerosis, coronary heart disease, etc.). On January 24, 2010, sibutramine was again banned from the market, as the potential risks of taking it would outweigh the possible benefits.
On the other hand, orlistat-based tablets act by reducing the absorption of dietary fats. As such they can cause flatulence, incontinence, oily manure and fecal urgency, especially after taking meals particularly rich in lipids.
In 2015, the European Medicines Agency approved the use of two new "anti-obesity" drugs to promote weight management in adult patients.
The two drugs - respectively based on the active ingredients naltrexone and bupropion (Mysimba ®) and liraglutide (Saxend ®) - act at the level of the brain centers that control satiety, reducing appetite and the amount of food consumed by patients.
Mysimba ® is available as extended-release tablets for oral intake, while Saxenda ® requires subcutaneous injection in the thigh, upper arm or abdomen.
There are also numerous other drugs with an important slimming effect but not approved for this purpose. These include thyroid hormones (see eutirox), acarbose, phendimetrazine and its analogues: phentermine, benzphetamine, diethylpropion and mazindole. Among the drugs banned for rather serious side effects, but alas still available on the black market, I recall for completeness the amphetamines (fenfluramine and dexfenfluramine) and phenylpropanolamine. All the pills for weight loss mentioned in this paragraph have specific side effects and contraindications; as such they must necessarily be taken under strict medical supervision, according to the recommended methods. General risks of abuse include thyroid dysfunction, pulmonary (primary pulmonary hypertension), brain (stroke) and cardiac (histological changes in the heart valves, hypertension) complications.
Even wider is the panorama of supplements for weight loss. Their effect is undoubtedly lower than that of the aforementioned drugs, but the risk of side effects is also generally low. Below is a brief overview of the most popular weight loss pills marketed as supplements.
ANOREXISANTS AND INTESTINAL ABSORPTION MODULATORS: dietary fiber supplements, taken together with generous quantities of water, swell inside the stomach, favoring the sense of satiety. Furthermore, they act in the intestine by modulating and reducing the absorption of fats and carbohydrates. Among these supplements for weight loss we remember: bran, guar and guar gum, karaya gum, psyllium, psyllium seeds, agar agar, glucomannan, pectin, flour Konjac, alginic acid and alginic acid, carrageenan. Fiber supplements should not be taken before bedtime, as, swelling rapidly, they could cause esophageal obstructions with consequent nocturnal asphyxia. In general, it is not recommended to use them in the presence of obstructions or inflammation. intestinal, pyloric stenosis, megacolon or megaretto, marked meteorism and functional dyspepsia. It should also be remembered that the massive intake of bran for therapeutic purposes significantly reduces intestinal absorption of calcium, zinc, magnesium and phosphorus, all essential elements for the body, especially during growth, in the elderly, in debilitated subjects and in women. In this case, it is essential to supplement the diet with vitamin and mineral supplements.
THERMOGENIC AND NERVINE FOODS: follow the action of catecholamines by promoting their release and / or stimulating their receptors; this determines an increase in the metabolic activity of the organism. The tablets and various extracts of bitter orange (unripe fruit) belong to this category. ), cocoa, coffee (seeds), cguarana (seeds), maté (leaves), ephedra (aerial parts), black tea (leaves), green tea (leaves) and yohimbe (stem bark). to lose weight is accompanied by well-known and dangerous adverse effects, psychic (agitation, nervousness, anxiety, insomnia) and cardiovascular (palpitations, tachycardia and hypertension).
SEAWEED SUPPLEMENTS: they are a generous source of iodine - essential mineral for the synthesis of thyroid hormones - and soluble fibers, such as alginates.The tablets containing extracts of marine algae (sea oak (fucus) and other algae) can therefore promote weight loss by supporting the metabolic activity of the organism and carrying out an anorectic effect. Overdosing can cause hyperthyroidism, thyroid dysfunction, tremors, irritability, hot flashes, tachycardia, insomnia and arterial hypertension. In general it is a good rule to consult your doctor in advance, to ascertain the absence of contraindications to the use of any tablet for weight loss. .
