Tsetirizin Geksal of a drop

General characteristics. Structure:

Active veshchestvo:tsetirizina dihydrochloride of 10 mg.

Auxiliary veshchestva:benzoyny acid, глицерол 85%, propylene glycol, the distilled water, sodium acetate trihydrate.

Pharmacological properties:

Pharmacodynamics. Tsetirizin possesses the expressed antiallergic action. Practically does not possess sedation in pharmacological active doses, treats the selection antagonists of H1-histamine receptors and has practically no anticholinergic and antiserotoninovy effect, prevents development and facilitates the course of allergic reactions. Has antipruritic and antiexudative effect. Influences an early stage of allergic reactions, and also reduces migration of cells of an inflammation; allocation of the mediators participating in late allergic reaction oppresses. Reduces permeability of capillaries, edematization of fabrics warns, removes a spasm of smooth muscles. Eliminates skin reaction to introduction of a histamine, offending allergens, and also to cooling (at a cold urticaria). Tsetirizin considerably lowers hyperreactivity of the bronchial tree arising in response to release of a histamine at patients with bronchial asthma. The therapeutic effect of drug is shown on average in 60 minutes after reception. Against the background of course reception tolerance does not develop.

Pharmacokinetics. Absorption: After intake цетиризин it is quickly and well soaked up from zheludochno – an intestinal path. The maximum level of concentration is defined approximately in 40 – 60 minutes.
Meal has no significant effect on absorption size, however in this case absorption speed slightly decreases.

Raspredeleniye:tsetirizin contacts proteins of a blood plasma approximately for 93%. The size of volume of distribution (Vd) low (0,5 l/kg), drug in a cell does not get.
Drug does not get through a blood-brain barrier.

Metabolizm:tsetirizin is poorly metabolized in a liver with formation of an inactive metabolite.
At 10-day use in a dose of 10 mg of accumulation of drug it is not observed.

Vyvedeniye:primerno for 70% occurs kidneys generally in not changed look.
The size of system clearance makes about 54 ml/min.
After a single dose of a single dose the size of an elimination half-life makes about 10 hours. At children aged from 2 up to 12 years the size of an elimination half-life decreases till 5-6 o'clock.
At a renal failure (the clearance of creatinine is lower than 11-31 ml/min.) and at the patients who are on a hemodialysis (clearance of creatinine less than 7 ml/min.) the size of an elimination half-life increases by 3 times, the clearance decreases by 70%.
Against the background of chronic diseases and at elderly patients increase in size of an elimination half-life by 50% and reduction of clearance by 40% is noted.
The hemodialysis is inefficient.

Indications to use:

Year-round and seasonal allergic rhinitis (symptomatic therapy); small tortoiseshell, including chronic idiopathic; the dermatosis proceeding with an itch (atopic dermatitis, neurodermatitis); allergic conjunctivitis.

Route of administration and doses:

Inside, irrespective of meal.
To adults and teenagers 12 years are aged more senior it is recommended to accept on 20 drops (10 mg) daily, preferably in the evening.
To children aged from 6-12 years on 10 drops (5 mg) twice a day in the morning and in the evening or on 20 drops (10 mg) in the evening.
To children at the age of 2-6 years on 10 drops (5 mg) in the evening or on 5 drops (2,5 mg) in the morning and in the evening.
To children at the age of 1-2 years on 5 drops (2,5 mg) twice a day.
At a renal failure it is necessary to reduce the recommended dose twice.
At an abnormal liver function it is necessary to select a dose individually, it is especially careful at a simultaneous renal failure.
With normal function of kidneys of correction of a dose it is not required to elderly patients.
Duration of reception is defined individually, usually at seasonal allergic rhinitis duration of therapy makes from 3 to 6 weeks, and at short-term influence of pollen happens enough and one week.

Features of use:

During treatment it is necessary to abstain from occupations potentially dangerous types of activity demanding the increased concentration of attention and speed of psychomotor reactions.
The simultaneous use of the means oppressing the central nervous system and alcohol intake is not recommended.

Side effects:

- From the alimentary system: dryness in a mouth, dyspepsia.
- From TsNS: headache, drowsiness, fatigue, dizziness, excitement, migraine.
Drug is usually well transferred. By-effects arise seldom and have passing character.

Interaction with other medicines:

It is not established clinically significant interactions of a tsetirizin with other medicines.
Joint use with theophylline (400 mg/days) leads to decrease in the general clearance of a tsetirizin (the kinetics of theophylline does not change).

Contraindications:

- Hypersensitivity in relation to a tsetirizin or other components of drug; serious illness of kidneys.
- Children's age till 1 year.
- Pregnancy, lactation period.

About ostorozhnostyyu:khronichesky pyelonephritis of average and heavy degree of manifestation (correction of the mode of dosing is required), advanced age (decrease in glomerular filtering is possible).

Overdose:

Simptomy:vozmozhna drowsiness, block, weakness, a headache, tachycardia, an acrimony, an urination delay, fatigue (most often at reception in day of 50 mg of a tsetirizin).
Lecheniye:provodit symptomatic therapy. The specific antidote is not revealed. The hemodialysis is inefficient. Carry out a gastric lavage, appoint absorbent carbon.

Storage conditions:

At a temperature not above 25 °C in the place, unavailable to children.

Issue conditions:

Without recipe
