INSTRUCTION FOR THE SPECIALIST.
Description of the drug approved by the manufacturer for the print edition of 2007.
PHARMACHOLOGIC EFFECT
The blocker of histamine H 1 -receptors. Has anti-allergic effect. Virtually does not have a sedative effect when used in recommended doses and has almost no anticholinergic and antiserotonin action, it prevents development and facilitates the course of allergic reactions. Has antipruritic and antiexsudative effect.
Affects the early stage of allergic reactions, and also reduces the migration of inflammatory cells; oppresses the selection of mediators involved in a late allergic reaction. Reduces the permeability of capillaries, prevents the development of edema of tissues, relieves spasm of smooth muscles. Eliminates the skin reaction to the administration of histamine, specific allergens, and also to cooling (with cold urticaria). Cetirizine significantly reduces the hyperreactivity of the bronchial tree, arising in response to the release of histamine in patients with bronchial asthma.
The therapeutic effect of the drug appears on average 60 minutes after admission. Against the background of the course, tolerance does not develop.
PHARMACOKINETICS
Suction
After ingestion, cetirizine is quickly and completely absorbed from the digestive tract. C max is achieved in 40-60 minutes.
Eating does not have a significant effect on the amount of absorption, but in this case, the rate of absorption is slightly reduced.
Distribution
Binding to plasma proteins is approximately 93%. V d is low and is 0.5 l / kg. Cetirizine does not penetrate the GEB and into the cells.
Metabolism
Cetirizine is metabolized to an insignificant degree in the liver with the formation of an inactive metabolite. When applied at a dose of 10 mg / day for 10 days, cumulation is not observed.
Excretion
It is excreted mostly by the kidneys (70%) mainly unchanged. Systemic clearance is about 54 ml / min. After a single dose of 10 mg T 1/2 is about 10 hours.
Pharmacokinetics in special clinical cases
In children aged 2 to 12 years, T 1/2 decreases to 5-6 hours.
If there is a marked violation of the kidney function (KK 11-31 ml / min) and in patients on hemodialysis (CC less than 7 ml / min), T 1/2 increases by 3 times, systemic clearance decreases by 70%.
Against the backdrop of chronic diseases and in the elderly, there is an increase in T 1/2 by 50% and a decrease in systemic clearance by 40%.
INDICATIONS
- All-the-year-round and seasonal allergic rhinitis (as symptomatic therapy);
- urticaria (including chronic idiopathic);
- dermatoses, flowing with itching (including atopic dermatitis, neurodermatitis);
allergic conjunctivitis.
