What is an antidote? Poisons and antidotes
When a large number of toxic substances enter the human body, poisoning occurs. This is an extremely dangerous phenomenon, which is associated with a serious negative effect of poisons on various organs and systems. In medical practice, antidotes are often used to combat the symptoms and effects of intoxication.
Substances that help cope with poisoning
What is an antidote? This term means a drug that helps neutralize the negative effects of toxic compounds. There is a synonym for this word - antidote. That is, the substance that has the effect is directly opposite the action of the toxin. When a person gets into the body, the poison breaks the work of various organs. The task of the antidote is to act on the nerve endings in such a way as to block the processes associated with the intake of toxins into the body.
Some antivenins work in such a way that they react with a dangerous substance and modify it. As a result, the toxin becomes harmless.
Features of the action of antidotes depend on their species.
Types of Toxins and Antidotes
When talking about what an antidote is and how it works, it should be noted that there are several varieties of such drugs. Each group of these means has its own peculiarities of work. Therefore, the choice of the antivenom variety depends on the specific case.
Toxins are known to affect certain organs and systems. In accordance with this, they are divided into several varieties, for example:
- Toxins that affect blood.
- Poisons destroying the central nervous system.
- Toxins affecting the muscle tissue.
- Poisons destroying the blood vessels.
- Toxins affecting the kidneys.

Antidotes for poisoning are natural and medicinal. Antidotes, which include natural ingredients, are called universal. That is, they can be used for poisoning by any substances. With regard to pharmaceuticals, they are used with extreme caution. It is advisable not to use such drugs without the permission of a doctor. With regard to medicinal antidotes, the classification of these agents includes the following:
- Local action antidotes( absorb toxic substances).
- Neutralizing antidotes( reacting with poison by chemical reaction, suppressing it).
- Means that modify toxins( convert them to safe substances).
- Physiological antidotes( remove from the body all harmful compounds, normalize its work).
- Immunological antidotes( vaccines, injections, stopping the action of toxins).

Although these drugs can be used for any type of poisoning, they are only auxiliary methods of helping the patient. In some cases, a person needs an urgent intake of an antidote drug. For example, if there has been poisoning with chemicals. One such dangerous compound is potassium cyanide. It is described in the next section.
Cyanide potassium: action per person. Help with intoxication
Potassium cyanide is one of the most dangerous toxins. It was a popular tool of criminals in the early twentieth century, when it could be purchased at any pharmacy. This substance was sold in the form of a powder.
Potassium cyanide is used for the processing of jewelry, in photography( as a fixer) and in the manufacture of paints. It is a part of the nuclei of fruit and berry seeds.

If you get potassium cyanide on the surface of the skin, you should rinse it thoroughly with water.
Drug poisoning
Continuing to talk about what an antidote is, it must be said that this remedy is often used to help with intoxication due to an overdose. This phenomenon is typical for people who are dependent on chemicals.

Specialists use various antidotes for overdose. The choice of the drug depends on which drug has caused intoxication. In case of an overdose, the most commonly used drugs are naloxope and galantamine.
Intoxication of unknown origin
Sometimes the patient has signs of poisoning, but it is not possible to find out what substance has an effect on the human body. In such situations it is necessary to use universal antidotes. These include:
- Unitiol( used for intoxication with heavy metals and drugs).
- Vitamin B6( used in acute conditions to improve overall health).
- Acid lipoic( with poisoning pale toadstool).
- Nalofrin( with morphine intoxication).
However, these funds, in spite of their universality, can only be used by a doctor. Therefore, for any poisoning it is better to wait for an ambulance.

However, vomit( antimony, copper sulfate) should be used with extreme caution. In case of intoxication with acid or alkali, the stomach should not be washed with the patient.
