Chelators, a list of medicines for children and adults

Chelators — drugs that are widely used in modern medicine for the purpose of removal from the body of toxic substances.

Belonging to this pharmacological group have a variety of effects: bind toxic substances, strukturiert intestinal contents, prevent the consequences of the reverse casting of toxins from the bloodstream into the intestine. The use of sorbents is shown in the majority of poisonings of exogenous (toxin comes from the external environment) and endogenous (toxin formed in the body) nature.

What are chelators?

Among the chelators include drugs having different structure, but United by a common ability to form complexes with toxic substances and pathogenic microorganisms contained in the stomach or intestine. Medical science distinguishes between 3 groups of assets related to these categories:

  • carbon;
  • silicon;
  • organic.

Carbon enterosorbents have a porous structure, through which are able to bind and securely hold a large number of toxic substances. Silicon kind of drugs well binds toxins, however, due to the smooth surfaces of the structural elements, may not reliably hold them. Therefore, the efficiency of silicon chelators are somewhat lower than carbon.

Organic chelators represent a complex of biopolymers (cellulose, lignin). In addition to the main actions of the drugs in this group have some laxative effect due to the swelling of the elements included in the composition of medicines, and increase stool bulk.

Unlike chelators from sorbents

The term «sorbents» in literal translation sounds like «absorbing». The value is too General to be used for the classification of medicinal substances. In today’s world, the sorbents used for purification of drinking water, air in the breathing apparatus and gas masks, in the manufacture of glass and porcelain. Medical sorbents in powder form can be applied directly to wounds to clean them in a liquid injectable form is administered intravenously or intramuscularly, used as medications for blood purification in filters for hemosorption.

The concept of «treatment» more narrow. This group includes only those medicines that are intended for ingestion. Drugs in this category absorb toxins and bacteria contained exclusively in the gastrointestinal tract of the patient. Enterosorbents — one of the subcategories for a large group of sorbents.

Interesting to know: some substances used for reception through the mouth, at the same time can be used for topical treatment. For example, activated carbon included in the filter to clean the blood.

When you want to apply chelators

The scope of the funds, possessing sorption properties, is quite broad. Drugs of this group are used when:

  • poisoning;
  • need bowel cleansing;
  • allergic reactions;
  • helminthiasis.

In specialized sources present information about the use of sorption means to lose weight. However, the effectiveness of the method remains unproven.

Poisoning

Poisoning is the main indication for prescription of chelators. The medications sorption assign regardless of the route of penetration of toxic substances in the body (through the mouth, through the skin, through the lungs, intravenously). The fact that almost all the toxins, after entering into the bloodstream partially released into the lumen of the intestine, where they are subjected to the action of the drug.

Prolonged uncontrolled intake of medicines can lead to constipation, an imbalance of intestinal flora, flatulence. Therefore, in the treatment of poisoning should obey the duration of therapy. So, for today the most known enterosorbent, activated carbon, the average duration of treatment is 7-10 days. More often, however, the drug overturned in 1-2 days after disappearance of symptoms.

Colon cleanse

For preventive cleansing of the bowel is more often used means of organic nature. As mentioned above, these drugs have the ability not only to bind toxic substances, but also to improve bowel movements, which makes them indispensable. The cleansing of toxins is carried out after a long stay in the zone of chemical contamination, when working in hazardous work, with frequent dysbiosis and functional disorders in the intestine.

For weight loss

By themselves, the chelators do not affect the amount of fat in the human body. With this purpose it is necessary to use special drugs for weight loss. However, in the complex treatment of obesity, severe sorbent means can really be applied. Their goal is deposition of some nutrients coming from food. Carbohydrates, fats and proteins, once bound by the sorbent, not absorbed into the bloodstream and excreted in unchanged form.

Chelators against allergies

One of the reasons of occurrence of external symptoms of Allergy is the formation in the body of endogenous toxins. The latter, as virtually any toxic substances, partially fall on the mucous membranes of the intestine. The use of chelators can bind and clear the body of the patient these toxins, and allergens trapped in the body through the gastrointestinal tract.

Helminthiasis

Sorption therapy for helminthiasis is of great therapeutic value. By assigning enterosorbents in the majority of cases it is possible to weaken the effect of intoxication arising from the release into the intestine of waste products of parasites. In addition, sorbents mitigate the consequences of the destruction of the bodies of worms in the treatment of extraintestinal parasitic infestations. Drugs with sorptive properties, must not be used simultaneously with anthelminthic drugs. Otherwise, the effect will be largely neutralized.

Effects on the body

In addition to the direct therapeutic effects, the chelators have a number of indirect effects:

  • prevention of allergic reactions;
  • debridement of ulcers of the gastrointestinal tract;
  • eliminate flatulence;
  • eliminating disbacteriosis;
  • mechanical irritation of the receptors and increased activity of the intestine;
  • reducing the functional load on the kidneys and liver in case of poisoning.

Chelators do not penetrate into the bloodstream and have systemic effects. Therefore, the number of side effects is minimal. Prolonged use of this group of funds may develop phenomena of increased gas formation, dysbiosis, in some cases, constipation. In addition, you should consider individual reactions of intolerance to the components included in the composition of a drug. If any of the described phenomena should reduce the dose or completely abandon its use.

Insights

The group of chelators is an excellent way to detoxify the body, cleanse the intestines. Also the drugs in this group have established ourselves as a substance has been used successfully in the treatment of helminthiasis, such as weight loss, allergic reactions.

Drugs that have the ability to settle on yourself and rid the body of toxic components, practically not absorbed in the intestine and do not have systemic action. Therefore, their application is relatively safe even in children. Despite this, the sorbents require caution. Their long-term uncontrolled use can cause constipation, vitamin deficiencies, exacerbation of other illnesses due to leveling actions taken simultaneously with the sorbent of drugs.

Take chelators are required in accordance with the indications for use. Better if you need the drug and the dosage regimen will be picked up by a competent expert. Only in this way can guarantee the successful completion of therapy in the shortest possible time.
