pharmachologic effect
Akatinol Memantine is a central muscle relaxant.
Being a non-competitive antagonist of N-methyl-D-aspartate (NMDA) receptors, it has a modulating effect on the glutamatergic system.
Regulates ion transport, blocks calcium channels, normalizes membrane potential, improves the transmission of nerve impulses, improves cognitive processes, memory and learning ability, and increases daily activity.

Side effects
Adverse reactions are classified by clinical manifestations (in accordance with the defeat of certain organ systems) and by the frequency of occurrence: very often - ≥1 / 10; often - ≥1 / 100–
On the part of the body as a whole - common adverse reactions Often Headache
Rarely Fatigue Infections
Rare fungal infections
Mental Disorders Often Drowsiness

Gastrointestinal Disorders
Often constipation
Rarely Nausea, Vomiting
Frequency not established Pancreatitis
Disorders from the central and peripheral nervous system
Often Dizzy
Rarely Gait Disorder
Very rare cramps
Hallucinations were mainly observed in patients with Alzheimer's disease at the stage of severe dementia.
There are separate reports of the occurrence of these adverse reactions when using the drug in clinical practice (data obtained after the drug was commercially available).
Interaction
With simultaneous use with L-dopa drugs, dopamine agonists, anticholinergics, the effect of the latter may be enhanced.
With simultaneous use with barbiturates, antipsychotics, the effect of the latter may decrease. When used together, it can change (strengthen or reduce) the effect of dantrolene or baclofen, so the doses of drugs should be selected individually. Concurrent administration with amantadine, ketamine, and dexamethorphan should be avoided.
Possible increase in plasma levels of cimetidine, procainamide, quinidine, kinin and nicotine while taking with memantine. It is possible to reduce the level of hydrochlorothiazide while taking it with memantine.
How to take, course of administration and dosage
Akatinol memantine taken orally , at meal time. The dosage regimen is set individually. It is recommended to start treatment with the appointment of minimally effective doses.
Adults with dementia during the 1st week of therapy - at a dose of 5 mg / day, 2nd week - at a dose of 10 mg / day, 3rd week - at a dose of 15-20 mg / day. If necessary, a further weekly increase in dose of 10 mg is possible until a daily dose of 30 mg is reached.
The optimal dose is achieved gradually, with increasing doses every week.
Overdose
Symptoms: increased severity of side effects.
Treatment: gastric lavage, intake of activated carbon, symptomatic therapy.
Special instructions
In patients with moderate to severe dementia, Alzheimer's disease usually impairs the ability to drive vehicles and control complex mechanisms.
In addition, memantine can cause a change in the reaction rate, so patients receiving treatment on an outpatient basis should be especially careful when driving vehicles or operating machinery.
