Kestin or Cetrin, which is more effective

Despite the general indications for use, Kestin and Cetrin are not completely interchangeable, therefore, the doctor should decide which antiallergic drug is best , depending on the age of the patient, the contraindications he has, and the tolerability of the therapy. Both adults and children can suffer from allergies. To stop its signs, Kestin and Cetrin preparations are used.

Kestin

Kestin contains as a main component ebastine, which relates to blockers of histamine H1-receptors. The medication has an antiallergic effect, the effect of it lasts up to 2 days.

Kestin shows almost no m-anticholinergic activity. It penetrates poorly into the central nervous system and does not have a strong sedative effect. Up to 90-95% of the accepted dosage is absorbed from the digestive tract. Passing through the liver, the drug is metabolized.

After eating fatty foods, absorption of Kestin is accelerated, and the concentration in the body increases by 1.5 times. Up to 95% of the dose taken is associated with proteins. The half-life of an antihistamine varies from 15 to 19 hours, with renal dysfunction, it lengthens up to 23-26 hours, with impaired liver function – 27 hours. It is excreted mainly through the kidneys.

Kestin

The Kestin treatment regimen is selected individually depending on the age of the patient:

Single dose in mg
5
10
10-20

Kestin should be drunk once a day. If the patient has impaired liver function, then the daily dosage should not exceed 10 mg.

Cetrin

Cetrin contains cetirizine as the main component , which belongs to the blockers of H1 histamine receptors and metabolites of hydroxyzine. It is a competitive histamine antagonist. Cetirizine prevents the occurrence of allergies and facilitates its course, relieves itching, has an antiexudative effect, and almost does not have an anticholinergic and antiserotonin effect.

The medicine reduces capillary permeability and eliminates spasm of smooth muscle tissue. Ceterizine suppresses the skin reaction to histamine, cold and specific allergens, prevents tissue swelling. It eliminates bronchospasm with a mild form of bronchial asthma.

Cetrin

If the medicine is taken in therapeutic doses, it almost does not have a sedative effect. After a single dose of Cetrin, the effect of it begins after 20 minutes and lasts up to a day.

When taking the drug in courses, addiction to it does not occur. After the therapy is over, the effect of the drug lasts for 3 days.

When taking Cetrin, it is rapidly absorbed from the digestive tract, its highest content is observed after an hour. Food does not alter absorption. But it lengthens the time to reach the maximum level by an hour and reduces the content of the drug by 23%. Up to 93% of the accepted dosage combines with proteins, so the medication is not removed during hemodialysis. The medicine in the body does not accumulate. The drug is excreted unchanged mainly with urine and in a small amount with feces.

The half-life depends on the age of the patient:

Half-life
3.1 h
5 h
6 h
10 h

In the elderly, the half-life can increase by 50%, and due to deterioration in renal function, systemic clearance decreases.

With renal and hepatic insufficiency, the period of life is lengthened. Cetrine is secreted through the mammary glands.

The treatment regimen is selected individually, depending on the age of the patient and the dosage form.
