The drug "Tsetrin". Indications and contraindications for use

To treat chronic allergies, as well as to prevent symptoms of its development, the drug "Cetrin" is often used. Indications for use can be different: it can be an allergic rhinitis and conjunctivitis (both seasonal and chronic), angioedema, chronic recurrent urticaria. It can also be used in the complex treatment of allergic and atopic dermatitis.

The drug "Tsetrin" is an antihistamine drug of the last generation, which does not have many side effects and contraindications to the effectiveness of the action. And what is histamine? It is a substance that transmits excitation from one cell to another, that is, it is a natural mediator. It is involved in inflammatory and allergic processes, and is also responsible for the acidity and secretion of gastric juice. The receptors, which are sensitive to histamine, are located on the cells of many tissues, they also provide the spread of an allergic reaction.

These reactions begin with the fact that leukocytes are directed to the focus of the allergy, which are responsible for the processes of confronting the organism with "dangers from the outside" - eosinophils that promote the development of inflammation, after which the "turn" of histamine comes. The indications available for the preparation "Tsetrin" include also a preventive effect that prevents the development of an allergic reaction due to the blockage of eosinophil migration at its early stage.

If the allergic reaction has already begun, then this drug is able to block these receptors, blocking the access of histamine to other cells and tissues. This is the main action of the medicine. Unlike the drugs of previous generations, the "Cetrin" remedy, which indications cover a wide range of allergic reactions of various origins, does not exert a retarding effect on the central nervous system and is effective for a long time (approximately within 24 hours).

Histamine, among other things, increases the permeability of blood vessels, which can cause swelling and redness of tissues. The drug "Tsetrin" is able to level this effect and prevent the decrease in blood pressure, which usually occurs with anaphylactic shock. It also facilitates the course of allergies at any stage.

The medicine "Tsetrin", indications for use which are not limited to allergy, can be used to eliminate itching of any origin, since histamine also participates in its formation.

This drug should be used in accordance with the instructions, one tablet per day, whether before or after meals. Take a small amount of water with a tablet. For children, the "Tsetrin" remedy can be prescribed at half the tablet twice a day. Until the age of six this means should not be used.

The drug "Tsetrin" during pregnancy during the first 12 weeks of use is strictly contraindicated, since the influence of histamine depends on the development of organs and the laying of the fetal tissues. It also promotes the introduction of a fertilized egg into the uterine wall and the development of the embryo. Suppression of histamine can disrupt these processes. In addition, reliable data on the effects of the "Tetrin" and other antihistamines are not available, since there are practically no clinical trials for pregnant women. After a 12-week period with great care, taking into account all indications and contraindications existing to the preparation "Tsetrin", it is possible to treat allergy with constant monitoring of the attending physician.

Do not take the drug during lactation, since it is excreted with milk. It is also contraindicated to use it for hypersensitivity to composite components. In diseases of the kidneys, accompanied by chronic renal failure, the drug is taken with caution and by no means alone.
