Pharmacodynamic properties

Film-coated tabletsCoated tablets

Citalopram is an antidepressant that belongs to the group of selective serotonin reuptake inhibitors. Having a pronounced ability to suppress serotonin reuptake, it does not or has a very weak ability to bind to a number of receptors, including histamine, muscarinic and adrenoreceptors. Citalopram inhibits cytochrome P4502D6 to a very small extent and, therefore, does not interact with drugs metabolized by this enzyme (the risk of side effects and toxic effects is lower).

The antidepressant effect usually develops after 2-4 weeks of treatment. Citalopram has practically no effect on the conducting system of the heart and blood pressure, on hematological parameters, liver and kidney function, and does not cause an increase in body weight.

Citalopram does not interfere with human cognitive functions, does not cause a sedative effect, in experimental studies, the drug has no teratogenic effect, no effect on reproductive function and perinatal development of offspring.

CitalAlcytam (Citalopram)m, having a pronounced ability to suppress serotonin reuptake, has no or little ability to bind to a number of receptors, including histamine, muscarinic and adrenoreceptors. It inhibits cytochrome P4502D6 only to a small extent and, therefore, does not interact with drugs metabolized by this enzyme. Thus, the side effects and toxic effects are much less pronounced. The antidepressant effect usually develops after 2-4 weeks of treatment. CitalAlcytam (Citalopram)m has virtually no effect on the cardiac conduction system and blood pressure, on hematological parameters, liver and kidney function, and does not cause an increase in body weight. CitalAlcytam (Citalopram)m does not interfere with human cognitive functions, does not cause a sedative effect. In experimental studies, the drug has no teratogenic effect, no effect on reproductive function and perinatal development of offspring

Pharmacokinetic properties

Film-coated tabletsCoated tablets

The bioavailability of citalopram is about 80% and is almost independent of food intake. Cmax in plasma, it is reached in 2-4 hours after administration. Binding to plasma proteins-less than 80%. In plasma, it is present in an unchanged form. At doses of 10-60 mg/day, the pharmacokinetic parameters have a linear relationship. The volume of distribution is 12 l/kg. The equilibrium concentration with a daily single dose is established after 7-14 days. Penetrates into breast milk.

It is metabolized by demethylation, deamination and oxidation with the participation of cytochrome P450 (isoenzymes CYP3A4 and CYP2C19) to form less pharmacologically active metabolites.

T1/2 - 1.5 days. Excretion is carried out by the kidneys and with feces.

Patients aged over 65 years

There is a longer biological T1/2 (1.5-3.75 days) and lower Cl values (0.08-0.3 l / min). The concentrations observed at steady state in elderly patients were almost 2 times higher than those observed in younger patients receiving the same dose.

Liver failure

In patients with reduced liver function, citalopram is excreted more slowly. The biological half-life of citalopram is almost 2 times longer and the equilibrium plasma concentrations of citalopram are almost 2 times higher compared to patients with normal liver function after administration of the same dose.

Insufficiency of kidney function

The elimination of citalopram proceeds more slowly in patients with a small to moderate degree of decrease in renal function without significant effect on pharmacokinetics.

The bioavailability of citalAlcytam (Citalopram)ma when taken orally is about 80% and practically does not depend on food intake. Cmax in plasma, it is reached in 2-4 hours after administration. Binding to plasma proteins-less than 80%. In plasma, it is present in an unchanged form. At doses of 10-60 mg/day, the pharmacokinetic parameters have a linear relationship.

It is metabolized by demethylation, deamination and oxidation with the participation of cytochrome P450 (isoenzymes CYP3A4 and CYP2C19) to form less pharmacologically active metabolites. T1/2 the preparation is 1.5 days. Excretion is carried out by the kidneys and with feces.

Patients aged over 65 years. There is a longer biological half–life (1.5–3.75 days) and lower clearance values (0.08-0.3 l/min). The concentrations observed at steady state in elderly patients were almost 2 times higher than those observed in younger patients receiving the same dose.

Insufficient liver function. In patients with reduced liver function, citalAlcytam (Citalopram)m is excreted more slowly. The biological half-life of citalAlcytam (Citalopram)ma is almost 2 times increased and the equilibrium plasma concentrations of citalAlcytam (Citalopram)ma are almost 2 times higher compared to patients with normal liver function after administration of the same dose.

Insufficiency of kidney function. The elimination of citalAlcytam (Citalopram)ma proceeds more slowly in patients with a small to moderate degree of decreased renal function without significant effect on pharmacokinetics. Currently, the experience of treating patients with severe renal insufficiency (creatinine Cl <20 ml / min) is insufficient.

Inside, at any time of the day, regardless of the meal, once.

Depression: the recommended daily dose of Alcytam (Citalopram) a is 20 mg. Depending on the individual patient's response to treatment and the severity of the disease, the dose can be increased, the maximum daily dose is 60 mg. Usually the antidepressant effect of the drug is observed after 2-4 weeks of treatment. Treatment with antidepressants should be carried out for a long time...

Panic disorders: the recommended daily dose is 10 mg during the first week of treatment, after which the dose is increased to 20 mg / day, the maximum daily dose is 60 mg. In the treatment of panic disorder, the maximum effect of citalopram is observed after 3 months of treatment. This effect persists throughout the entire period of maintenance therapy.

Obsessive-compulsive disorder: the recommended daily dose is 20 mg. Depending on the individual response of the patient to treatment and the severity of the disease, the dose can be increased, the maximum daily dose is 60 mg. In the treatment of obsessive-compulsive disorder, the effect of the drug appears after 2-4 weeks of treatment, with continued treatment, further improvement may be observed.

In patients aged 65 years and older, the maximum daily dose is no more than 40 mg.

Impaired renal function: patients with slightly or moderately impaired renal function can use the drug in normal doses. Currently, the experience of treating patients with severe renal insufficiency (creatinine Cl below 20 ml/mol) is insignificant.

Impaired liver function: patients with impaired liver function should not be prescribed more than 30 mg/day.

Inside, 1 time a day at any time, either with food or on an empty stomach.
