Pharmacological properties
Pharmacodynamics
Azelastine is a histamine H 1 receptor blocker derived from phthalazinone. It has a long-term antiallergic and membrane stabilizing effect.
The main effects of azelastine:
- decrease in capillary permeability and decrease in exudation;
- stabilization of mast cell membranes and preventing the release of biologically active substances from them (including serotonin, histamine, leukotrienes, platelet activating factor), which cause bronchospasm and contribute to the early and late stages of allergic reactions and inflammation;
- reduction of itching and nasal congestion, sneezing, rhinorrhea.
The systemic effect of azelastine when applied topically is insignificant.
Relief of symptoms of allergic rhinitis is usually noted 15 minutes after drug administration, its duration is 12 hours or more.
When carrying out long-term therapy with high doses of the drug, a clinically significant effect of azelastine on the QT interval is not observed.
Pharmacokinetics
The bioavailability of azelastine after intranasal administration of Allergodil is approximately 40%. The time to reach C max (maximum concentration of the substance) in the blood is from 2 to 3 hours. When using the spray at the recommended daily dose (1.1 mg), C ss (equilibrium concentration) in the blood is less than 1% of the dose. The serum concentration of the substance in the blood after intranasal administration is 8 times lower than after oral administration. In patients with allergic rhinitis, the concentration of azelastine in the blood is higher than in healthy people.
C max with repeated use of Allergodil eye drops (4 times a day, 1 drop in each eye) is very low and is detected at the limit / below the measurement limit.
Other pharmacokinetic parameters have been studied with oral azelastine.
The blood protein binding is 80–90%.
Azelastine metabolism occurs in the liver by oxidation with the participation of the cytochrome P450 system, followed by the formation of desmethylazelastine, an active metabolite.
It is excreted mainly in the form of inactive metabolites. The main route of elimination is through the kidneys. T 1/2 (half-life) of azelastine and desmethylazelastine is approximately 20 and 45 hours, respectively.
