excipients:

Microcrystalline cellulose – 34.870 mg,

lactose monohydrate – 18,000 mg,

sodium carboxymethyl starch (sodium starch glycolate, type A) – 14,000 mg,

povidone K-30 – 8,000 mg,

talk – 5,000 mg,

colloidal silicon dioxide – 3,000 mg,

magnesium stearate – 2,000 mg;

film coating:

[hypromellose – 3,600 mg, talc – 1,200 mg, titanium dioxide – 0,660 mg, macrogol 4000 (polyethylene glycol 4000) – 0,540 mg] or [dry film coating mixture containing hypromellose (60%), talc (20%), titanium dioxide (11%), macrogol 4000 (polyethylene glycol 4000) (9%)] – 6,000 mg.

How to take, the dosage

Orally, 2 times daily, regardless of meals.
Treatment of acute and chronic psychosis, including schizophrenia.
The daily dose for the first 4 days of therapy is 50 mg (day 1), 100 mg (day 2), 200 mg (day 3), 300 mg (day 4). Starting on day 4, the dose should be titrated to effective, ranging from 300 to 450 mg/day, up to 750 mg/day if necessary.

Treatment of manic episodes in the structure of bipolar disorder.

Quetiapine is used as monotherapy or as adjuvant therapy for mood stabilization.

The daily dose for the first 4 days of therapy is 100 mg (day 1), 200 mg (day 2), 300 mg (day 3), 400 mg (day 4). Further, by the 6th day of therapy, the daily dose of the drug can be increased to 800 mg. Increase in the daily dose should not exceed 200 mg per day.

Depending on clinical effect and individual tolerance, the dose may vary from 200 to 800 mg/day. Usually the effective dose is 400 to 800 mg/day.

For treatment of schizophrenia, the maximum recommended daily dose of quetiapine is 750 mg; for treatment of manic episodes in the structure of bipolar disorder, the maximum recommended daily dose of quetiapine is 800 mg/day.

In renal and/or hepatic impairment and in elderly patients, the initial dose is 25 mg/day, with daily increases of 25-50 mg thereafter until an effective dose is achieved.

Interaction

In concomitant administration of drugs with strong inhibitory effect on CYP3A4 (such as azole antifungals and macrolide antibiotics), plasma concentration of quetiapine may increase.

In such cases, lower doses of vetiapine should be used. Particular attention should be paid to elderly and frail patients. The risk-benefit ratio for each patient must be evaluated individually.

Inducers of microsomal liver systems (phenytoin etc.), thioridazine increase clearance of quetiapine, inhibitors of microsomal liver systems decrease it; at the same time simultaneous administration of quetiapine and antidepressants – imipramine (CYP2D6 inhibitor) or fluoxetine (CYP3A4 and CYP2D6 inhibitor) has no significant effect on its pharmacokinetics.

The pharmacokinetics of quetiapine is not significantly altered when prescribed concomitantly with the antipsychotic drugs risperidone or haloperidol.

Does not cause induction of liver enzyme systems involved in antipyrine metabolism.

Pharmacokinetics of lithium preparations are not altered by concomitant administration of quetiapine.

No clinically significant changes in the pharmacokinetics of valproic acid and quetiapine have been noted when divalproex sodium (sodium valproate and valproic acid in a molar ratio of 1:1) and Quetiapine are co-administered.

Drugs that depress the central nervous system and ethanol increase the risk of side effects.

Special Instructions

No correlation between quetiapine administration and QTc interval prolongation has been found. However, caution should be exercised when using vetiapine concomitantly with drugs that prolong the QTc interval.

In children, adolescents and young adults (younger than 24 years) with depression, other psychiatric disorders, antidepressants, compared with placebo, increase the risk of suicidal thoughts and suicidal behavior. Therefore, when prescribing antidepressants in children, adolescents, and young adults (younger than 24 years), the risk of suicide and the benefits of their use should be weighed.

In short-term studies, people over the age of 24 had no increased risk of suicide, and people over the age of 65 had a slightly decreased risk of suicide. Any depressive disorder itself increases the risk of suicide. Therefore, all patients should be monitored during antidepressant treatment for early detection of impairment or behavioral changes as well as suicidal tendencies.

During treatment, caution should be exercised when driving motor vehicles and engaging in other potentially hazardous activities that require increased concentration and rapid psychomotor reactions.
