Pharmachologic effect

Mode action - antiallergic, antipruritic, antiexudative, H1-antihistamine.

Pharmacodynamics

Levocetirizine - (R) -enantiomer of cetirizine, a competitive histamine antagonist, blocks H1-histamine receptors, whose affinity is two times higher than that of cetirizine. It affects the histamine-dependent stage of allergic reactions, reduces the migration of eosinophils, vascular permeability, and limits the release of inflammatory mediators. Prevents development and facilitates the course of allergic reactions, has an antiexudative, antipruritic effect, has almost no anticholinergic and antiserotonin effect. In therapeutic doses, the sedative effect is very poorly expressed. The action begins 12 minutes after a single dose in 50% of patients, after 1 hour - in 95% and lasts for 24 hours. Does not affect the QT interval on the ECG.

Pharmacokinetics

Pharmacokinetics is linear in nature, independent of dose and time, and varies insignificantly among different people.

Absorption. Quickly absorbed when taken orally; Food intake does not affect the fullness of absorption, but reduces its speed. Bioavailability of 100%. Tmax - 0.9 h, Cmax in the blood - 207 ng / ml. Vd - 0,4 l / kg. The degree of absorption depends on the dose and is not disturbed by eating, but when you eat Cmax decreases and slows down its achievement.

Distribution. Levocetirizine binds to plasma proteins by 90%. Data on the distribution of levocetirizine in tissues and its penetration through the BBB in humans are absent. Levocetirizine penetrates into breast milk.

Metabolism. In humans, less than 14% of the dose of levocetirizine is metabolized; The expected differences in the pharmacokinetic profile of levocetirizine due to genetic polymorphism or simultaneous administration of enzyme inhibitors are negligible. Metabolic transformations consist in oxidation of the aromatic ring, N- and O-dealkylation, and conjugation with taurine. The dealkylation process is mainly carried out with the CYP3A4 isoenzyme, while the oxidation of the aromatic ring is carried out by many and / or unidentified CYP isoforms. Levocetirizine when administered orally at a dose of 5 mg and / or excess of Cmax in blood plasma does not affect the activity of CYP isoenzymes 1A2, 2C9, 2C19, 2B6, 2E1, 3A4. Due to limited metabolism and the absence of metabolic inhibitory activity, the interaction of levocetirizine at the metabolic level with other substances is unlikely.

Excretion. T1 / 2 - 7-10 hours. The total clearance is 0.63 ml / min / kg. Completely eliminated from the body for 96 hours, mainly with urine (85.4% of the dose).

Renal insufficiency. The total clearance of levocetirizine depends on the creatinine clearance, therefore, patients with moderate and severe renal insufficiency are recommended to increase the intervals between doses of the drug in accordance with the creatinine clearance. In patients with anuria and terminal stage of renal failure, the total clearance of levocetirizine is reduced by approximately 80% compared to that in healthy people. The amount of levocetirizine withdrawn with a standard 4-hour hemodialysis procedure is less than 10%.

Indications of the Glencet

Symptomatic treatment of the following conditions and diseases:

Year-round and seasonal allergic rhinitis and allergic conjunctivitis (itching, sneezing, rhinorrhea, lacrimation, congestion hyperemia);

Application in pregnancy and breastfeeding

The use of the drug in pregnancy is contraindicated.

Levocetirizine is excreted in breast milk, so if it is necessary to use the drug in lactation it is recommended to stop breastfeeding.

Side effects

Side effects of levocetirizine are divided according to the system-organ classes according to the classification of the Medical Dictionary of Regulatory Activities (MedDRA) with the frequency of their occurrence: often (≥1 / 100 and <1/10); Infrequently (≥1 / 1000 and <1/100); Very rarely (<1/10000).

Interaction

The interaction of levocetirizine with other drugs has not been studied.

Studies of the interaction of the racemate cetirizine showed no clinically significant interaction with pseudoephedrine, cimetidine, ketoconazole, erythromycin, azithromycin, glipizide, and diazepam.

Theophylline (400 mg / day) reduces the total clearance of cetirizine by 16%, while the kinetics of theophylline does not change.

With the simultaneous administration of ritonavir (600 mg twice daily) and cetirizine (10 mg per day), the exposure of cetirizine increases (40%), and the exposure of ritonavir varies insignificantly.

The degree of absorption of cetirizine does not decrease under the influence of food, although the rate of absorption decreases.

In a number of cases, with the simultaneous use of levocetirizine with ethanol or drugs that have an inhibitory effect on the central nervous system, it is possible to intensify this action.

Dosing and Administration

Inside, not liquid and squeezed liquid, regardless of food intake. It is recommended to take a daily dose at one time.

Adults, teenagers and children over 6 years. The recommended daily dose is 5 mg (1 table).

Patients of advanced age. In elderly patients with moderate and severe renal failure, dose adjustment is recommended (see Impairment of kidney function below).

Impaired renal function. The interval between doses is determined individually, taking into account the function of the kidneys. Information on dose adjustment is given in the table below. For its use, the creatinine clearance in the patient (in ml / min) based on serum creatinine concentration (mg / dl) should be calculated using the following formula: Cl creatinine = (140 - age, years) × mass, kg / 72 × creatinine Blood serum, mg / dl (× 0.85 for women).

Table 1

Correction of dose in patients with impaired renal function

Group Clcreatinine, ml/min Dose and multiplicity of admission
Normal function ≥80 5 mg 1 per a day
Easy CRF 50–79 5 mg 1 per a day
Moderate CRF 30–49 5 mg 1 per in 2 days
Severe CRF <30 5 mg 1 per in 3 days
Terminal CRF - patients on dialysis <10 Contradicted

In children with impaired renal function, the dose is adjusted individually, taking into account the clearance of creatinine and body weight. There are no separate data for use in children with impaired renal function.

Violation of the function of the liver. With an isolated violation of liver function, dose adjustment is not required. In patients with hepatic renal failure, dose adjustment is recommended (see Abnormal kidney function above).

Duration of treatment

There is a clinical experience of the continuous use of levocetirizine for up to 6 months in adult patients.

In the treatment of seasonal (intermittent) allergic rhinitis (the presence of symptoms less than 4 days per week or a total duration of less than 4 weeks), the duration of treatment depends on the duration of the symptomatology; Treatment can be stopped if symptoms disappear and are resumed when symptoms appear.

In the treatment of year-round (persistent) allergic rhinitis (the presence of symptoms more than 4 days a week and their total duration of more than 4 weeks) treatment can continue throughout the exposure period of allergens.

The course of treatment is determined by a doctor; The average is 1-6 weeks.

In chronic diseases (including chronic idiopathic urticaria), the course of treatment can be longer in agreement with the doctor.

Overdose

Symptoms: drowsiness in adults and agitation, as well as anxiety, followed by drowsiness, in children.

Treatment: there is no specific antidote to levocetirizine. Symptomatic or maintenance treatment is recommended. If you take a little time after taking the medication, you should wash the stomach. Levocetirizine is practically not excreted in hemodialysis.

Special instructions

During treatment with the drug is not recommended to take ethanol.
