1 dose contains:
Active agent: azelastina hydrochloride of 0,140 mg

Description: transparent colourless or almost colourless solution.




Pharmacological properties:

Azelastin, derivative a ftalazinona, is antiallergic means of long action. Being the selection H1-gistaminoblokatorom, has antihistaminic, antiallergic and membrane stabilizing effect, reduces permeability of capillaries and exudation, stabilizes membranes of mast cells and interferes with release from them biologically active agents (a histamine, serotonin, leukotrienes, the factor activating thrombocytes, etc.) causing a bronchospasm and promoting development of an early and late stage of allergic reactions and an inflammation. At topical administration systemic action insignificant.
At intranasal introduction reduces an itch and a congestion of a nose, sneezing and a rhinorrhea. Weakening of symptoms of allergic rhinitis is noted since 15 min. after use and continues till 12 o'clock and more.
Clinically significant impact on QT (QTc) an interval is absent even at prolonged use of high doses of an azelastin.

Pharmacokinetics. Bioavailability after intranasal use about 40%.
 The maximum concentration (Cmax) in blood after intranasal use is reached in 2-3 hours. At use intranazalno in a daily dose of 0,56 mg of an azelastin of a hydrochloride (one injection in each nasal course twice a day) average equilibrium concentration of an azelastin of a hydrochloride in plasma in 2 hours after reception makes 0,65 ng/ml.
Doubling of the general daily dose to 1,12 mg (two injections in each nasal course twice a day) results in steady average concentration of an azelastin in the plasma equal 1,09 ng/ml.
However, despite rather high absorption at patients, system influence after intranasal use is about 8 times lower, than after oral administration of the daily dose of 4,4 mg of an azelastin of a hydrochloride which is a therapeutic peroral dose for treatment of allergic rhinitis.
Intranasal use for patients with allergic rhinitis causes increase in level of an azelastin in a blood plasma in comparison with healthy subjects.
Other pharmacokinetic data are studied at use inside.
Communication with blood proteins of 80-90%.
It is metabolized in a liver by oxidation with participation of system of P450 cytochrome with formation of an active metabolite of a dezmetilazelastin. It is removed generally by kidneys in the form of inactive metabolites.
Elimination half-life (T1/2) of an azelastin – about 20 h, its active metabolite of a dezmetilazelastin – about 45 h.


Indications to use:

• Treatment of seasonal and year-round allergic rhinitis (including hay fever) and rinokonjyunktivita.

In these cases it is not recommended to drive the car and to work with dangerous mechanisms. Alcohol intake can strengthen these phenomena.


Side effects:

Frequency of development of side effects is determined as follows:
Very often:> 1/10;
Often: <1/10> 1/100;
Infrequently: <1/100> 1/1000;
Seldom: <1/1000> 1/10000;
Very seldom: <1/10000.

Often - as a result of the wrong way of introduction when the head is thrown back back, emergence of bitter taste in a mouth is possible that in rare instances can make sick.
Infrequently – the weak, passing irritation of the inflamed mucous membrane of a nose which is shown burning, an itch, sneezing, in rare instances nasal bleeding.
