Allergic diseases and allergic reactions are very common today. For relief of the symptoms of these diseases are produced different drugs. Tsetrin belongs to the third generation of allergy drugs - blockers of histamine H1 receptors.
What is histamine and how it works
Histamine - a biologically active substance which acts as a mediator transmitting excitation with cells on the cell. Histamine is involved in allergic and inflammatory processes, stimulates gastric acid secretion. In the cells of many tissues are small molecules - receptors sensitive to histamine - namely through them a signal to start an allergic reaction.
Receptors sensitive to histamine are found in the skin, mucous membranes of the respiratory tract and are called H1-histamine receptor responsible for allergic processes. There are histamine H2 retsepotry, they are located in the stomach wall and responsible for the secretion and the acidity of gastric juice.
Action tsetrina on the body
Tsetrin available in tablets of 10 mg and has a selective blocking effect on the histamine H1-receptors that histamine searches through access to the tissues. This drug belongs to the third generation drugs blockers H1-histamine receptors.
The first generation of drugs (diphenhydramine, suprastin) has a marked inhibitory effect on the central nervous system, as these drugs are easily penetrates the brain. Their action was effective, but short-lived. Preparations of the second generation (ketotifen) worked for quite some time, had almost no side effects in the form of sleepiness, but other side effects was quite a lot.
Finally, tsetrin, which refers to the third generation, operates during the day and almost devoid of side effects, including drowsiness. Tsetrin Available in tablets for oral administration, which can be taken regardless of meals. Tsetrin well removes histamine induced permeability of small blood vessels (reduced redness and swelling of the tissues), prevents a sharp drop in blood pressure
Blood pressure - dangerous if his swing?
(decrease in blood pressure can occur in anaphylactic shock), make it easier for allergic reactions in their very beginning, and in the further development.
Home allergic reactions characterized by aspiration to the fire allergy eosinophils (a type of white blood cells responsible for the allergic processes), which promote the development of allergic inflammation. And then in the "work" includes histamine.
Tsetrin prevents the migration of eosinophils, so it can stop the allergic reaction at the very beginning and even prevent its occurrence, if the patient takes it in advance, as a prophylactic measure. If an allergic reaction in a heat, then turn on the main mechanism of action tsetrina - blocking H1 histamine receptors. Thus tsetrin be used to prevent allergic reactions, as well as at any stage of their development.
With which diseases and how to apply
Tsetrin very convenient to use for chronic allergic processes in order to prevent symptoms of allergies. It can be taken in the allergic rhinitis and conjunctivitis and perform regular work. He saves people suffering from hay fever (seasonal allergies related to pollen of flowering plants), which for some reason were not able to leave the danger zone during the flowering period.
If there is a person allergic to stings of any insect, the reception tsetrina prevent the emergence of allergic reactions, such as during outdoor recreation.
Any allergic reactions may occur dangerous spread of hives (rash maculopapular, prone to an increase in his eyes and merge into large patches) and edema
Prevention and treatment of edema - it is important to understand the root cause
Angioedema - swelling of the connective tissue, which can spread to the soft tissues of the larynx, including the vocal cords. Tsetrin prevents or relieves such allergic reactions.
Finally, you can take tsetrin itching of any origin, as in the formation of histamine itch is always involved, and tsetrin blocking its action.
