Zodak: pharmachologic effect
Allergy medication, gistaminovыh blocker H1-receptors. Cetirizine belongs to the group of competitive antagonists of histamine. It has a pronounced anti-allergic effect, prevents and facilitates the allergic reactions. It has antipruritic and antiexudativ effect. It affects the early stage of allergic reactions, and also reduces the migration of inflammatory cells; inhibits release of mediators, involved in the late allergic reaction. Decreases capillary permeability, prevents the development of edema, relieves smooth muscle spasm. Eliminates skin reaction to the introduction of histamine, specific allergens, and cooling (when cold urticaria).
Virtually no anticholinergic action and antiserotoninovogo.
At therapeutic doses substantially no sedative effect. Against the background of course taking the tolerance does not develop.
Preparation action begins 20 m (in 50% patients) or via 1 no (in 95% patients) and maintained for a 24 no.
Zodak: pharmacokinetics
Absorption
After oral cetirizine is rapidly and almost completely absorbed from the gastrointestinal tract. Cmax plasma is determined approximately 30-60 m. Food intake has no significant effect on the value of removals, however, in this case, the rate of absorption is reduced insignificantly.
Distribution
The binding of cetirizine plasma proteins is approximately 93%. The value Vd Low - 0.5 l / kg. Cetirizine does not penetrate into the cell. Do not cross the BBB.
Metabolism
Cetirizine poorly metabolized in the liver with the formation of active metabolites.
At 10 days of administration at a dose 10 mg cumulation is not observed.
Deduction
After a single administration of a single dose of T1/2 is about 10 no. About 70% excreted by the kidneys in a largely unaltered. The value of systemic clearance is about 54 ml / min.
Pharmacokinetics in special clinical situations
Children between the ages of 2 to 12 T years1/2 is reduced to 5-6 no.
If the kidney function (KK from 11 to 31 ml / min) and patients, hemodialysis (CC less than 7 ml / min), T1/2 increases 3 times, ground clearance is reduced by 70%.
Against the background of chronic diseases and elderly patients noted an increase in T1/2 on 50% and a decrease in the clearance 40%.
Cetirizine does not appear in hemodialysis.
