Release form

Company "Aegis"Alerzin produces in the form of oral drops in 20 ml bottles and in the form of tablets of 7 or 14 pieces in a pack.

Pharmachologic effect

Antihistamine.

Pharmacodynamics and pharmacokinetics

The active ingredient of Alerzin is levocetirizine - is a stable R-enantiomer Cetirizine and belongs to a group of competitive histamine blockers.

Therapeutic efficacy levocetirizinedue to its ability to block Histamine H1 receptorsto which the affinity for levocetirizinetwice this indicator cetirizine. Alerzin's influence on histamine dependentformation phase allergic reaction possibly due to reduction vascular permeabilitydecrease eosinophil migration and limiting release inflammatory mediators. Levocetirizineprevents formation allergic reactionsand their further development thanks to their anti-exudative, anti-inflammatory and antipruritic effects. The antiserotonin and anticholinergic effects of the drug are practically not observed.

Linear dependence of pharmacokinetic parameters levocetirizinesimilar to that of cetirizine.

Oral administration levocetirizineleads to its intense and rapid absorption. The degree of absorption is not dose-dependent and does not change from taking the drug with or without food, but when taking drugs with food, its Cmax slightly decreases. Bioavailability levocetirizineis at the level of 100%. In half of the patients, the effectiveness of a single dose (5 mg) of the drug is observed after 12 minutes, and in 95% of patients after 30-60 minutes. The plasma Cmax of the therapeutic oral dose is 270 ng / ml, is reached over 50 minutes and lasts two days. With repeated administration of 5 mg levocetirizineits Cmax reaches a value of 308 ng / ml.

Accurate distribution information levocetirizinein the tissues of the human body and its passage through the BBB does not exist. According to studies, the maximum concentrations of the drug were recorded in kidneyand liver, and the minimum in CNS tissues. Binding to plasma proteins occurs at 90%. The volume of distribution is 0.4 l / kg.

In the human body, only 14% undergoes metabolic transformation levocetirizineby connecting mechanisms such as N- and O-dealkylation, oxidation and compound with T aurin. The dealkylation process primarily affects the system cytochrome CYP3A4, and uncertain and / or numerous isoforms of CYP. In concentrations that are significantly higher than the maximum after oral administration of 5 mg levocetirizine, its effect on activity is not observed cytochrome isoenzymes 1A2, 2E1, 2C19, 2C9, 2D6, 3A4. Given the low rates metabolism drug, as well as the lack of levocetirizinethe ability to suppress it, the interaction of Alerzin with other medicinal substances is unlikely.

The main ways of excretion levocetirizine - it is active tubular secretion and glomerular filtration. For adult patients, T½ of the drug from plasma is 7.9 ± 1.9 hours (in children less), the total clearance is 0.63 ml / min / kg. The majority of levocetirizine and its metabolic products are excreted by the kidneys - on average, 85.4%, approximately 12.9% are excreted by the intestines.

In the human body, the actual clearance levocetirizinedirectly related to ground clearance creatininetherefore patients with kidney pathologies Alerzine should be prescribed with appropriate creatinine clearance at intervals. With anuria, the actual clearance of the body decreases by about 80% compared with the actual clearance of the body of healthy people. During hemodialysis (4-hour procedure) less than 10% levocetirizine.

For patients with renal pathologies, dose adjustment is carried out in accordance with the observed creatinine clearance (CC):

  • KK 30-49 ml / min - 5 mg once in 48 hours;
  • CC less than 30 ml / min - 5 mg once in 72 hours;
  • CC less than 10 ml / min - contraindicated.

If it is necessary to prescribe Alerzin to children with kidney pathologies, the dosage regimen of the drug is adjusted individually based on QC and the weight of the child.

Treatment duration

With occasionally occurring allergic rhinitis with symptoms lasting less than 4 days a week or less than 4 weeks, a therapy is prescribed that is consistent with the history and course of the disease. It is possible to stop treatment when symptoms disappear and resume when they reappear.

In the case of a chronic course of diseases (hivesand allergic rhinitis) the duration of taking Alerzin can be up to 12 months.

Overdose

In case of overdose levocetirizineobserved signs drowsiness in adult patients, as well as primary excitationand irritabilitywith further drowsinessin pediatric patients.

Interaction

Concurrent use with Pseudoephedrine, Antipyrine, Cimetidine, Glipizide, Erythromycin, Azithromycin, Ketoconazole, Diazepamdid not show any clinically significant negative interactions.

In a multiple-dose combined daily dose study cetirizine 10 mg and daily doses ritonavira1200 mg distribution ritonaviradecreased by 11%, and exposure cetirizineincreased by 40%.

Joint reception with Theophylline in a daily dose of 400 mg reduces the actual clearance levocetirizineby 16%, without changing the kinetics theophylline.

Degree of absorption levocetirizinedoes not depend on food intake, but reduces the rate of its absorption.

When applying levocetirizinein therapeutic dosages enhancing the effects of concurrently taken sedatives funds were not observed, however, the joint administration of these drugs is not recommended.

Combined use with drugs, overwhelming central nervous system and ethanol-containingdrugs, did not affect the enhancement of their effects, however, in sensitive patients, such a drug combination could theoretically affect the normal functionality of the central nervous system.

Vitamins protect an unborn baby from autism

A group of scientists at the University of California came up with an interesting theory: women who took vitamin complexes during pregnancy planning, as well as in the first months after it, are half as likely to give birth to a child with autism. Studies have shown that taking vitamin supplements is primarily able to help women with a hereditary predisposition to this kind of deviation.
