Mysoline indications: epilepsy (seizures, focal seizures, myoclonic seizures and akinetic seizures, complex partial seizures). Mysoline is not effective for other forms of epilepsy (non-convulsive status epilepticus, epilepsy with polymorphic seizures, etc.).
Primidone is almost completely absorbed from the gastrointestinal tract. The maximum concentration can be reached within 3 hours. The drug is excreted by the kidneys.

Mysoline (primidone) is unacceptable in the following cases:
- Hypersensitivity;

Mysoline should be used with caution with carbamazepine, diphenylhydantoin, and other anticonvulsants.
Primidone enhances the effect of hypnotic drugs, sulfonylurea derivatives, cyclophosphamide, methotrexate.
The drug accelerates metabolism and reduces the effect of paracetamol, indirect anticoagulants, tricyclic antidepressants, chloramphenicol, cyclosporine, doxycycline, levothyroxine, metronidazole, digitalis glycosides (digoxin to a lesser extent), disopyramide, mexiletine, quinidine, fenoprofen, aminophylline, caffeine, theophylline, vitamin D.
Mysoline may lead to CNS depression when combined with alcohol.
Amphetamine slows the gastrointestinal absorption of the drug.
Mysoline enhances the toxic effect of drugs for general anesthesia (enflurane, halothane, methoxyflurane).
Primidone reduces the absorption of griseofulvin (reduces the antifungal activity of griseofulvin).
Guanethidine, haloperidol, maprotiline, molindone, loxapine, phenothiazines, and thioxanthenes may lead to central nervous system depression.
When used in large doses, leucovorin (folinic acid) reduces the effect of primidone.
Methylphenidate inhibits the metabolism of primidone and increases its concentration in the blood (this can lead to toxic effects).
Hormones released by the posterior pituitary increase the risk of arrhythmias and coronary insufficiency.
Valproic acid may increase the concentration and toxicity of primidone.
Other antiepileptic drugs reduce the effectiveness of primidone.
Primidone may reduce the effectiveness of oral contraceptives. It is necessary to use other methods of contraception during treatment.
Primidone may reduce the effectiveness of paracetamol.
