Pharmacological action

Blocker of the peripheral histamine H1-receptors. Has anti-allergic effect. Does the early stage gistaminozavisimuyu allergic reactions, reduces the migration of eosinophils, restricts the release of inflammatory mediators in late, cell stage of allergic reactions. Prevents the development and facilitates during allergic reactions, has antipruritic effect.

Almost no anticholinergic and antiserotoninovogo action. In therapeutic doses does not cause a sedative effect. The maximum therapeutic effect is achieved within 4-8 hours after drug administration and lasts up to 24 hours



After oral cetirizine rapidly and well absorbed from the gastrointestinal tract. Cmax plasma levels achieved after 30-60 min. Eating has no significant effect on the magnitude of absorption, but in this case the rate of absorption slightly reduced.


Binding to plasma proteins is 93%. Vd is about 0.5 L / kg. Do not cross the BBB and into the cell. In applying the drug at a dose of 10 mg for 10 days accumulation of the drug is not observed.


Cetirizine poorly metabolized in the liver with the formation of an inactive metabolite.


About 70% of applied dose cetirizine kidneys derived largely unchanged. After a single dose of a single dose of T1 / 2 is about 10 hours

Pharmacokinetics in special clinical situations

In chronic diseases and elderly patients indicate an increase in T1 / 2 by 50% and a decrease in clearance by 40%.

seasonal and perennial allergic rhinitis;

Precautions should be prescribed the drug in patients with chronic renal failure, moderate and severe (requires correction dosing regimen), as well as elderly patients (possibly reducing the glomerular filtration).

Pregnancy and lactation

Allertek not recommend use during pregnancy. If necessary, use during lactation should decide on the termination of breastfeeding.

Application for violations of liver function

Patients with severe hepatic impairment dose is reduced.

Application for violations of renal function

Patients with severe impaired renal function reduce the dose.


Be wary prescribers elderly and patients with impaired liver function and / or kidneys. Patients should notify the need to inform your doctor about any side effects occur against a background of the drug.
