List of antihistamines of the new generation: a list of the best 2019

Antihistamines - are substances that inhibit the action of histamine free.

When ingested, allergen, histamine is released from mast cells of connective tissue within the body's immune system. He begins to interact with specific receptors and cause itching, swelling, rash and other allergic reactions. For blocking these receptors are responsible antihistamines. In 2019, there are three generations of these drugs.

Today we look at a new generation of antihistamines, they are effective and virtually no side effects. To-date for 2019 the list of such drugs can be found in the article. Write your own review in the comments, you can.

Causes of allergies

The main causes of allergies:

  • the waste products of mites;
  • pollen of various flowering plants;
  • foreign protein compounds contained in vaccines or donor plasma;
  • exposure to sun, cold;
  • dust (portrait, home, outside);
  • spores of different fungi or mold;
  • Animal hair (mostly typical for cats, rabbits, dogs, chinchillas);
  • Chemical detergents and cleaners;
  • therapeutic drugs (anesthetics, antibiotics);
  • insta story viewer
  • food, mostly eggs, fruits (oranges, persimmons, lemons), milk, nuts, wheat, seafood, soy, berries (cranberry, grape, strawberry);
  • insect / arthropod bites;
  • latex;
  • cosmetics;
  • psychological / emotional stress;
  • Unhealthy Lifestyle.

Actually allergies can be identified by the sudden watery eyes, runny nose, itching, sneezing, redness of the skin and other unexpected morbid manifestations. Most often such allergic symptoms occurs by direct contact with the substance-specific allergen, detects a human body as an agent of the disease, so that it triggers counter.

Physicians considered as allergens, as substances that reveal a direct allergenic action, so agents capable of increasing the effects of other allergens.

The response of human response to exposure to various allergens depends on the genetic characteristics of the individual's immune system. Reviews of carrying out numerous studies indicate the presence of a hereditary allergic predisposition. So parents with allergies are much more likely to have a child with a similar pathology than in healthy couples.


Protivogistaminnye prescribe drugs, including the latest generation you have to doctor make an accurate diagnosis. Typically, their reception expedient in the presence of such symptoms and diseases:

  • early atopic syndrome child;
  • seasonal or year-round rhinitis;
  • negative reaction to pollen, animal dander, house dust, certain medications;
  • heavy bronchitis;
  • angioedema;
  • anaphylactic shock;
  • food allergies;
  • enteropathy;
  • asthma;
  • atopic dermatitis;
  • conjunctivitisCaused by exposure to allergens;
  • chronic, acute and other forms of urticaria;
  • atopic dermatitis.

The mechanism of action of antihistamines

The basis of the mechanism of action applied against allergy medications - their ability to reverse the inhibition of histamine H1-receptors.

They can not fully substitute for histamine, but effectively block those receptors that he could not take. That is why they are used when necessary to prevent the fast-growing and difficult runs allergies. H1 blockers also interfere with the production of new batches of histamine, if the disease is actively developing. Modern anti-allergy drugs can affect not only histamines, but also on bradykinin, serotonin and leukotrienes.

When interacting with receptors H1 cause the following effects:

  1. Antispasmodic action.
  2. Bronchodilator effect if, after exposure to histamine spasm occurred.
  3. Inhibit vasodilatation.
  4. normalizes vascular permeability wall, particularly in the capillary bed.

Antihistamines may not affect gastric acid secretion and acidity, since it does not interact with the histamine H2 receptors.

Generation antihistamines

There are several generations of antihistamines. With each generation decreases the number and strength of side effects and the likelihood of addiction, the duration increases.

Below is the classification adopted by WHO in 2019:

Generation: Active substance:
First generation.

Generation Antihistamines 1 characterized by the following pharmacological properties:

  • reduced muscle tone;
  • have sedative, hypnotic and holinoliticheskoe effect;
  • potentiate the effects of alcohol;
  • have a local anesthetic effect;
  • give fast and strong, but short-term (4-8 hours) the therapeutic effect;
  • long reception reduces antihistamine activity, so every 2-3 weeks means change.
  • Chloropyramine;
  • dimethindene;
  • diphenhydramine;
  • clemastine;
  • mebhydrolin;
  • meclizine;
  • promethazine;
  • chlorphenamine;
  • Sehifenadin;
  • Dimenhydrinate.
Second generation.

They have the advantage over the first-generation drugs:

  • holinolitichesky no sedative effect and, since these drugs do not overcome
  • blood-brain barrier, but some people experience mild drowsiness;
  • mental activity, physical activity does not suffer;
  • exposure to the drugs up to 24 hours, so they are taken once a day;
  • They are not addictive, that allows you to assign them a long time (3-12 months);
  • upon discontinuance of the drugs, the therapeutic effect lasts for about a week;
  • Medicines are not adsorbed to food in the gastrointestinal tract.
  • cetirizine;
  • terfenadine;
  • astemizole;
  • azelastine;
  • acrivastine;
  • loratadine;
  • ebastine;
  • hifenadina;
  • Rupatadin;
  • Karebastin.
The last generation (third).

All the latest generation antihistamine drugs have cardiotoxic and sedation, so they can apply those whose work is related to the high concentration of attention.

These drugs inhibit H1-receptors, and also to have an additional effect on allergic manifestations. They have high selectivity, do not overcome the blood-brain barrier, so they are not peculiar to the negative effects of the central nervous system, there is no spillover effect on the heart.

  • levocetirizine;
  • desloratadine;
  • fexofenadine;
  • Norastemizol.

Chemical structure and properties

Allergy medications can be divided into several types depending on their chemical structure. Depending on the type and structure formed pronounced effects and properties.

product type: species: Characteristic features:
Etanolominy Clemastine, diphenhydramine, dimenhydrinate, doxylamine Pronounced sedation, drowsiness, m-holinolitichesky effect.
ethylenediamines Chloropyramine Pronounced sedation, drowsiness, m-holinolitichesky effect.
alkylamines Dimethindene, acrivastine, chlorphenamine Causes increased excitation of the central nervous system, but there is little sedative effect.
piperazines Cetirizine, hydroxyzine Weak sedation.
piperidines Ebastine, loratadine, levocabastine, fexofenadine Weak sedation prakicheski not affect the nervous system and have no anticholinergic properties.
phenothiazines Promethazine, hifenadina Pronounced holinoliticheskie, antiemetic properties.

In order to decide what is best antihistamines, it is necessary to consider their distinctive features, advantages and disadvantages, as well as the impact on the patient and allergy itself.

Development H1 receptor blockers occurred gradually, and today there are three generations of drugs, each of which has its own characteristics.

Antihistamines 4 generations - Do They Exist?

All statements creators of advertising, positioning brands of drugs as a "fourth-generation antihistamine drugs" - nothing more than a publicity stunt. This pharmacological group does not exist, although marketers refer to it not only the newly created drugs, but also the second-generation drugs.

Antihistamines in Pregnancy

It is natural that women with allergies, planning to become pregnant or are already wearing a child's heart, very interested in what anti-allergy pills you can drink during pregnancy and subsequent lactation, and whether during these periods to take such drugs principle?

Let's start with the fact that during pregnancy the woman is better to avoid taking any medicinal drugs as their action may be dangerous for pregnant women and for their unborn offspring.

In trimester 2 and 3 also allows the use of antihistamines enormous limitations, since none of the existing medicinal allergy drugs is not one hundred percent safe.

Allergic women who suffer from seasonal allergies, can be recommended to plan in advance the time of her pregnancy, when the specific allergens are least active. For the rest the best solution would also avoid contact with the substances causing them allergic reactions. Failing such recommendations, the severity of some allergic reactions can reduce the intake of natural antihistamines (fish oil, vitamin B12 and C, zinc, pantothenic, nicotine and oleic acid), and then only after consulting doctor.
