Pharmachologic effect

Mode action - antiallergic.

Pharmacodynamics

Levocetirizine, (R) -enantiomer of cetirizine, is an inhibitor of peripheral H1-histamine receptors, whose affinity is 2 times higher than that of cetirizine. After a single administration of levocetirizine, H1-histamine receptor binding was observed to be 90% after 4 hours and 57% at 24 hours.

Levocetirizine influences the histamine-dependent stage of allergic reactions, reduces the migration of eosinophils, reduces vascular permeability, limits the release of inflammatory mediators, prevents the development and facilitates the course of allergic reactions, has antiexudative, antipruritic effect, practically no anticholinergic and antiserotonin action, Sedative action.

The effect of levocetirizine begins 12 minutes after a single dose in 50% of patients, after 1 hour in 95% of patients and continues for 24 hours. Levocetirizine does not affect the QT interval on the ECG.

Pharmacokinetics

The pharmacokinetics of levocetirizine is linear in nature, independent of dose and time, and varies only slightly in different patients.

After ingestion, levocetirizine is rapidly and completely absorbed from the digestive tract.

The intake of food does not affect the completeness of absorption, although its rate decreases.

Plasma Cmax is achieved after 0.9 hours (54 min) after taking the drug.

Css is installed after 2 days. Plasma Cmax after a single dose of 5 mg of levocetirizine is 270 ng / ml, and after repeated administration at a dose of 5 mg - 308 ng / ml.

Levocetirizine binds to plasma proteins by 90%. Vd is 0.4 l / kg. Data on the distribution of levocetirizine in tissues and its penetration through the BBB in humans are absent.

Levocetirizine is metabolized in small amounts (<14%) in the body by N- and O-dealkylation (unlike other antagonists of H1-histamine receptors that are metabolized in the liver by the cytochrome system) to form a pharmacologically inactive metabolite.

Due to limited metabolism and the absence of metabolic inhibitory activity, the interaction of levocetirizine at the metabolic level with other substances is unlikely. T1 / 2 in adults is 7.9 ± 1.9 hours; In young children, T1 / 2 is shortened. The average observed total clearance is 0.63 ml / min / kg.

Levocetirizine is mainly excreted unchanged in urine, on average, about 85.4% of the dose taken by glomerular filtration and active tubular secretion. Excretion through the intestine (with feces) is only 12.9% of the dose.

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

Indications of the Zodac Express

Treatment of symptoms of year-round (persistent) and seasonal (intermittent) allergic rhinitis and allergic conjunctivitis such as itching, sneezing, nasal congestion, rhinorrhea, lacrimation, congestion hyperemia;

Pollinosis (hay fever);

Urticaria, including, chronic idiopathic urticaria;

Quincke's edema (as an adjuvant therapy);

Other allergic dermatoses, accompanied by itching and rashes.

Contraindications

Hypersensitivity to levocetirizine and other piperazine derivatives or to any of the auxiliary components of the drug;

Terminal renal failure with Cl creatinine less than 10 mL / min;

Congenital galactose intolerance, lactase deficiency or malabsorption of glucose-galactose (due to the content of lactose in the preparation)

pregnancy;

Children under 6 years of age (for this dosage form).

With caution: simultaneous reception with alcohol (see "Interaction"); Chronic renal failure with Cl creatinine more than 10 ml / min, but less than 50 ml / min (dosage adjustment is required); Elderly age (probably a decrease in glomerular filtration).

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).

From the side of the immune system: very rarely - hypersensitivity reactions, incl. Anaphylactic reactions.

From the nervous system: often - headache; Infrequently - drowsiness; Very rarely - aggression, agitation, hallucinations, depression, convulsions.

From the side of the organ of vision: very rarely - visual disorders.

From the heart: very rarely - a feeling of palpitations, tachycardia.

From the respiratory system, chest and mediastinum: very rarely - shortness of breath.

From the gastrointestinal tract: often - dryness of the oral mucosa; Infrequently - pain in the abdomen; Very rarely - nausea, diarrhea.

From the liver and biliary tract: very rarely - hepatitis.

From the skin and subcutaneous tissues: very rarely - angioedema, itching, rash, including a drug rash, urticaria.

From the musculoskeletal and connective tissue: very rarely - myalgia.

Common violations: often - fatigue; Infrequently, asthenia.

From laboratory and instrumental data: very rarely - a violation of liver function indicators, weight gain.

Interaction

The interaction of levocetirizine with other drugs, including studies with inducers of the isoenzyme CYP3A4, has not been studied.

In the study of the drug interaction of the racemate cetirizine with pseudoephedrine, cimetidine, ketoconazole, erythromycin, azithromycin, glipizide and diazepam, clinically significant undesirable interactions have not been identified.

With simultaneous appointment with theophylline (400 mg / day), the total clearance of cetirizine is reduced by 16% (theophylline kinetics does not change).

In a study with simultaneous administration of ritonavir (600 mg twice daily) and cetirizine (10 mg per day), it was shown that the exposure of cetirizine increased by 40%, and exposure to ritonavir slightly changed (11%).

In sensitive patients, concomitant administration of levocetirizine and alcohol or other substances depressing the CNS can exacerbate the effect on the central nervous system, although it has been shown that the racemate of cetirizine does not enhance the effect of alcohol.

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 Patients with impaired renal function).

Patients with impaired renal function. The interval between doses of the drug is determined individually, taking into account the function of the kidneys. Information on dose adjustment is given in the table below. To use it, creatinine Cl creatinine should be calculated in a patient in ml / min based on serum creatinine concentration (mg / dl) using the following formula:

Cl creatinine = ([140 - age, years] × weight, kg) / (72 × serum creatinine, mg / dL)

For women, the value obtained should be multiplied by 0.85.

Table

Correction of dose in patients with impaired renal function

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

Patients with impaired hepatic function. With an isolated violation of liver function, dose adjustment is not required. In patients with hepatic renal failure, dose adjustment is recommended (see Patients with impaired renal function).

Duration of treatment. Treatment of allergic rhinitis is carried out in accordance with the course of the disease; The drug can be stopped if symptoms disappear and resume when relapsed. In the case of chronic allergic rhinitis, prolonged treatment during the period of action of allergens can be prescribed. Currently, the clinical experience of using levocetirizine in the form of tablets coated with a film membrane, 5 mg, is limited to 6 months.

Overdose

Symptoms: drowsiness and agitation (in adults) are possible, as well as anxiety, followed by drowsiness (in children).

Treatment: there are no specific antidotes of levocetirizine. In case of an overdose, symptomatic or supportive 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.

Impact on the ability to drive vehicles or engage in other potentially hazardous activities. Levocetirizine, when administered at recommended doses, does not adversely affect the attention and speed of psychomotor reactions and the ability to drive vehicles. Nevertheless, during the period of taking the drug, it is advisable to refrain from engaging in potentially dangerous activities that require an increased concentration of attention and speed of psychomotor reactions.
