Pharmacological properties
It is an antiepileptic medication. It has an anti-manic, normotimic (normalizing mood) effect. The active substance activates the inhibitory GABAergic system in the brain. It also blocks the voltage-dependent Na-channels of the membranes of nerve cells, which leads to the stabilization of their function, reduces the activity of neurotransmitter acids (aspartate, glutamate), interacts with brain adenosine receptors. Increases the seizure threshold, corrects epileptic personality changes.

• with epilepsy;
• with complex and simple partial convulsive seizures (with / without loss of consciousness, with / without signs of secondary generalization);
• with mixed forms of convulsive seizures;

• with AV block;
• with inhibition of bone marrow function;
• with hepatic porphyria (acute intermittent, mixed, late porphyria of the skin), incl. in past;

Children
Due to the faster elimination of carbamazepine, children may need to use higher doses of the drug (per kilogram of body weight) compared to adults. The tablets can be taken by children over 5 years of age.

Application during pregnancy and lactation
Mezacar is contraindicated during these periods.

Method of application and dosage
Mezacar should be administered orally; usually the daily dose of the drug should be divided into two or three doses. The drug can be taken during, after a meal or in between meals with a small amount of liquid, such as a glass of water.
Treatment should begin with a low daily dose with a gradual increase in the dose of the drug, which should be adjusted to the needs of each patient.
To select the optimal dose of the drug may be useful to determine the level of carbamazepine in blood plasma.
Especially in the case of combination therapy, therapeutic doses should be calculated based on the determination of plasma carbamazepine levels and efficacy.
Experience has shown that therapeutic levels of carbamazepine are in the range of 4-12 μg / ml.

• Adults: the recommended initial dose of the drug is 100-200 mg 1-2 times a day. Then slowly increase the dose to achieve the optimal effect; often the daily dose is 400 mg twice or thrice a day (corresponding to 800-1200 mg). Some patients may require a dose of Mezacar of up to 1,600 mg or even 2,000 mg per day, although these high doses should be avoided due to the higher frequency of adverse events.
• Elderly patients: the dose of Mezacar should be carefully considered in elderly patients due to possible drug interactions. The recommended starting dose is 100 mg twice a day.
• Children: treatment can be started with 100 mg / day; increase the dose gradually – every week by 100 mg.
  The usual dose of the drug is 10-20 mg / kg body weight per day (taken in several doses).

Age of the child in relation to the daily dose:

• 5-10 years – 400-600 mg (for 2-3 receptions);
