Inside.

Children over 6 years old and adults : initial dose - 5 mg (1/2 table. or 10 drops) once a day, if necessary, can be increased to 10 mg (1 table. or 20 drops) 1 time a day. Sometimes the initial dose is 5 mg (1/2 tab. or 10 drops) may be sufficient to achieve a therapeutic effect. Daily dose - 10 mg (1 table. or 20 drops).

Children from 6 to 12 months : 2.5 mg (5 drops) 1 time per day.

Children from 1 year to 2 years : 2.5 mg (5 drops) up to 2 times a day.

Children from 2 to 6 years old : 2.5 mg (5 drops) 2 times a day or 5 mg (10 drops) 1 time a day.

Sick with renal failure, the dose decreases depending on the creatinine clearance: with Cl creatinine 30–49 ml / min - 5 mg 1 time per day, at 10–29 ml / min - 5 mg per day.

Because Incidal-OD^® excreted by kidneys, when prescribing the drug, patients with renal failure and elderly patients should be adjusted to the extent of creatinine clearance. Creatinin clearance for men can be calculated based on the concentration of serum creatinine, according to the following formula:

Cl creatinine, ml / min

Creatinine clearance for women can be calculated by multiplying the value obtained by a coefficient of 0.85.

For adult patients with renal and liver failure, dosing is carried out according to the table above.

Children with renal failure are adjusted for creatinine clearance and body weight.

Patients with impaired liver function only do not need to correct the dosing mode.

Inside.

Drops dissolve in a small amount of water before taking.

Adults and adolescents over 12 years old: 10 mg (20 drops or 1 table.) once a day, preferably at night.

Children aged 6–12 years: 5 mg each (10 drops or 1/2 table.) 2 times a day (morning and evening) or 10 mg (20 drops or 1 whole tablet) in the evening.

Children aged 1-6 years It is recommended to designate Incidal-OD^® in the medicinal form of a drop for taking in.

Children aged 2–6 years: 5 mg (10 drops per day) once. You can also divide this dose by 2 doses of 2.5 mg (5 drops in the morning and evening).

Children aged 1-2 years: 2.5 mg (5 drops) 2 times a day.

Special patient groups

It may be necessary to reduce the dose of y elderly patients.

At kidney function violation the dose should be set individually, in accordance with the function of the kidneys. The table below will assist in the selection of doses. To use this table, you should evaluate Cl creatinine in a patient in ml / min. After determining the concentration of creatinine of blood serum (mg / dl), the value of Cl creatinine can be estimated using the following formula:

Cl creatinine = [(140 − age, years) × body weight, kg) / (72 − creatinine blood serum, mg / dl]

When calculating creatinine clearance for women, the result must be multiplied by 0.85. The table shows the doses depending on Cl creatinine.

Table

The dose selection depending on the clearance of creatinine

Inside, dig into a spoon or dissolve in water.

The amount of water for dissolving the drug must correspond to the amount of fluid that the patient (especially the child) is able to swallow. The solution should be taken immediately after preparation.

Adults. 10 mg (20 drops) 1 time per day. Sometimes an initial dose of 5 mg (10 drops) can be enough if this allows satisfactory control of the symptoms.

Elderly age. In elderly patients with normal kidney function, there is no need to reduce the dose.

Violation of the function of the kidneys. When prescribing the drug to patients with impaired renal function, in the case when alternative treatment cannot be prescribed, the dose should be adjusted depending on the value of Cl creatinine, since cetyrizin is removed from the body mainly by the kidneys.

The Cl creatinine indicator for men can be calculated based on the concentration of serum creatinine in the blood plasma according to the following formula:

Cl creatinine, ml / min = (140 - age, years) × body weight, kg) / (72 × Cl creatinine_serum, mg / dl).

Cl creatinine for women can be calculated by multiplying the value obtained by a coefficient of 0.85.

Violation of liver function. Patients with impaired liver function do not need to correct the dosing mode. In patients with impaired liver function and kidneys, dosing correction is recommended (see. table above).

Children. The use of children from 6 to 12 months is possible only by appointment of a doctor and under strict medical supervision. Children from 6 to 12 months — 2.5 mg (5 drops) 1 time a day; from 1 year to 6 years — 2.5 mg (5 drops) 2 times a day; from 6 to 12 years — 5 mg (10 drops) 2 times a day; over 12 years old — 10 mg (20 drops) 1 time a day, sometimes the initial dose is 5 mg (10 drops) may be enough, if this allows satisfactory control of the symptoms.

Children with renal failure are adjusted for Cl creatinine and body weight.

Instructions for opening a bottle

The bottle is closed with a lid with a safety device that prevents children from opening it. The bottle opens when the lid is pressed heavily down, followed by screwing it off counterclockwise. After using the bottle cover, you must screw it tight again.

Inside, swallowing in its entirety, drinking with a small amount of water, regardless of the time of eating.

Cetirizin is an active substance of the drug Incidal-OD^® - is a metabolite of hydroxysine, belongs to the group of competitive antagonists of histamine and blocks H₁histamine receptors.

Cetirisin warns development and facilitates the course of allergic reactions, and has antitudent and anti-exudative effect. Cetirisin affects the early histone-dependent stage of allergic reactions, limits the release of inflammation mediators at a late stage of an allergic reaction, and also reduces the migration of eosinophiles, neutrophils and basophiles, stabilizes the membranes of fat cells. Reduces the permeability of capillaries, prevents the development of tissue edema, relieves the spasm of smooth muscles. Eliminates the skin reaction to the introduction of histamine, specific allergens, as well as cooling (with cold urticaria). Reduces histin-induced bronchocongricia with bronchial asthma of the light current.

Cetirisin does not have an anti-cholinergic and anti-serotonin effect. In therapeutic doses, the drug has virtually no sedative effect. After taking cetyrizin in a single dose of 10 mg, its action develops after 20 minutes (in 50% of patients), after 60 minutes (in 95% of patients) and lasts more than 24 hours. Against the background of course treatment, tolerance for the antihistamine action of cetyrizin does not develop. After the cancellation of therapy, the effect persists up to 3 days.

Cetirisin is a metabolite of hydroxisin, belongs to the group of competitive antagonists of histamine and blocks N₁- histamine receptors.

In addition to the antihistamine effect, cetyrizin prevents development and facilitates the course of allergic reactions: at a dose of 10 mg 1 or 2 times a day inhibits the late phase of the aggregation of eosinophiles in the skin and conjunctiva of patients exposed to atopia.

Clinical efficiency and safety. Studies in healthy volunteers have shown that cetirisin in doses of 5 or 10 mg significantly inhibits the reaction in the form of rash and redness to inject histamine into the skin at a high concentration, but a correlation with efficiency has not been established. A 6-week placebo-controlled study involving 186 patients with allergic rhinitis and concomitant bronchial asthma of mild to moderate currents shows that taking cetrizin at a dose of 10 mg 1 time per day reduces the symptoms of rhinitis and does not affect the function of the lungs.

The results of this study confirm the safety of the use of cetyrin in patients suffering from allergies and bronchial asthma of the mild and medium-lived course.

A placebo-controlled study showed that taking cetrizin at a dose of 60 mg / day for 7 days did not cause a clinically significant extension of the QT interval. Taking cetyrin in the recommended dose showed an improvement in the quality of life of patients with year-round and seasonal allergic rhinitis.

Children. In a 35-day study involving patients aged 5–12 years, there were no signs of immunity to the antihistamine effect of cetyrizin. The normal reaction of the skin to the histamine was restored within 3 days after the abolition of the drug when it was repeatedly used.

A 7-day placebo-controlled study of cetyricine in the form of syrups involving 42 patients aged 6 to 11 months demonstrated the safety of the drug.

Cetirizin was assigned at a dose of 0.25 mg / kg 2 times a day, which approximately corresponded to 4.5 mg per day (dose range ranged from 3.4 to 6.2 mg per day).

The use of children from 6 to 12 months is possible only by appointment of a doctor and under strict medical supervision.

The pharmaceutical parameters of cetyrizin change linearly.

Suction. After taking it inside, the drug is quickly and completely absorbed from the LCD. Eating does not affect the completeness of absorption, although its speed decreases. In adults, after a single medication in therapeutic dose C_max in blood plasma is 300 ng / ml and is achieved through (1 ± 0.5) h.

Distribution. Cetirisin on (93 ± 0.3)% binds to blood plasma proteins. V_d is 0.5 l / kg. When taking the drug at a dose of 10 mg for 10 days, cetyrizin cumulation is not observed.

Metabolism. In small quantities, it is metabolized in the body by O-dealkylation (unlike other antagonists H₁-histamines that are metabolized in the liver using a cytochrome system) with the formation of pharmacologically inactive metabolite.

The conclusion. In adults T_1/2 is approximately 10 hours; in children from 6 to 12 years old - 6 hours, from 2 to 6 years old - 5 hours, from 6 months to 2 years old - 3.1 hours. Approximately 2/3 of the accepted dose of the drug is withdrawn by the kidneys unchanged.

In elderly patients and patients with chronic liver diseases with a single medication at a dose of 10 mg T_1/2 increases by about 50%, and system clearance is reduced by 40%.

In patients with renal failure of mild severity (Cl creatinine> 40 ml / min), pharmacokinetic parameters are similar to those in patients with normal kidney function.

In patients with moderate renal failure and in patients undergoing hemodialysis (Cl creatinine <7 ml / min), when taking the drug inward at a dose of 10 mg T_1/2 lengthens 3 times, and the total clearance is reduced by 70% relative to these indicators in patients with normal kidney function, which requires a corresponding change in the dosing mode.

Cetirisin is practically not removed from the body during hemodialysis.

The pharmaceutical parameters of cetyrizin when used in doses of 5 to 60 mg change linearly.

Suction. C_max in blood plasma is achieved through (1 ± 0.5) h and is 300 ng / ml.

Various pharmacokinetic parameters, such as C_max in blood plasma and AUC are homogeneous.

Eating does not affect the completeness of cetyrizin absorption, although its speed decreases. The bioavailability of various dosage forms of cetyrizin (rathering, capsules, tablets) is comparable.

Distribution. Cetirisin on (93 ± 0.3)% binds to blood plasma proteins.

V_d is 0.5 l / kg. Cetirisin does not affect the binding of warfarin with proteins.

Metabolism. Cetirisin is not exposed to extensive primary metabolism.

The conclusion. T_1/2 is approximately 10 hours.

When taking the drug in a daily dose of 10 mg for 10 days, cetyrizin cumulation was not observed.

Approximately 2/3 of the accepted dose of the drug is withdrawn with urine in an unchanged form.

Elderly patients. In 16 elderly patients with a single medication in a dose of 10 mg T_1/2 was 50% higher, and clearance was 40% lower compared to patients of not old age. The decrease in cetirizin clearance in older patients is probably due to a decrease in the function of the kidneys in this category of patients.

Renal failure. In patients with renal failure of mild severity (Cl creatinine> 40 ml / min), pharmacokinetic parameters are similar to those in healthy volunteers with normal kidney function.

In patients with moderate renal failure and in patients undergoing hemodialysis (Cl creatinine <7 ml / min), when taking the drug inward at a dose of 10 mg T_1/2 lengthens 3 times, and the overall clearance is reduced by 70% relative to healthy volunteers with normal kidney function.

For patients with renal failure of moderate or severe degree, a corresponding change in the metering mode is required (see. “Method of application and doses”).

Cetirisin is poorly removed from the body during hemodialysis.

Pediatric failure. In patients with chronic liver diseases (hepatocellular, cholestatic and biliar cirrhosis) with a single medication at a dose of 10 or 20 mg T_1/2 increases by about 50%, and clearance is reduced by 40% compared to healthy entities. Correction of the dose is necessary only if the patient with liver failure also has concomitant renal failure.

Children. T_1/2 in children from 6 to 12 years old it is 6 hours, from 2 to 6 years old - 5 hours, from 6 months to 2 years old - reduced to 3.1 hours.

When studying the drug interaction of cetyrizin with pseudoephedrine, cimetidine, ketokonazole, redytromycin, azithromycin, diazepam, glypidine and antipyrin, clinically significant unwanted interactions were not detected.

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

With simultaneous use with AUC ritonavir, cetyrizin increased by 40%, while the same indicator of the ritonavir slightly changed (−11%).

With simultaneous use with macrolides (azitromycin, red bloodmicin) and ketoconazole, changes to the ECG were not noted.

When using the drug in therapeutic doses, data on the interaction with alcohol were not obtained (at a blood alcohol concentration of 0.5 g / l). Nevertheless, one should refrain from drinking alcohol during therapy with a drug in order to avoid oppression of the central nervous system.

A three-day “laundering” period is recommended before the appointment of allergological samples due to the fact that H₁-histamines blockers inhibit the development of skin allergic reactions.

No medicinal interactions of cetyricin with other drugs were noted.

Based on the results of studies of the drug interaction of cetyrizin, in particular studies of the interaction with pseudoephedrine or theophyllin at a dose of 400 mg / day, there were no clinically significant interactions.

The simultaneous use of cetyrizin with alcohol and other drugs that depress the central nervous system can further reduce the concentration and speed of reactions, although cetrizin does not increase the effect of alcohol (at its concentration in the blood of 0.5 g / l).

It is not recommended to combine taking the drug Zinzet with other drugs without a doctor’s consultation. At the same time, taking with broncholithic drugs containing the theophylline as the active substance, an increase in the frequency of side effects of the drug Zincet. Data on the interaction of cetyricine with alcohol has not yet been received. Despite this, the use of alcoholic beverages in the treatment of Zincet is not recommended.

It is not recommended to combine the use of Incidal-OD with other drugs without a doctor’s consultation. With simultaneous use with broncholithic drugs containing the theophylline as the active substance, an increase in the frequency of side effects of the drug Incidal-OD. Data on the interaction of cetyrizin with alcohol has not yet been received. Despite this, the use of alcoholic beverages in the treatment of Incidal-OD is not recommended.
