Pharmacological action

Antioxidant preparation. Ethylmethylhydroxypyridine succinate (EMHPS) is an inhibitor of free radical processes, a membrane protector with antihypoxic, stress-protective, nootropic, anticonvulsant and anxiolytic effects. Belongs to the class of 3-hydroxypyridines. The mechanism of action is due to antioxidant and membrane-protective properties.

Suppresses lipid peroxidation, increases superoxide oxidase activity, increases lipid-protein ratio, improves cell membrane structure and function. It modulates the activity of membrane-bound enzymes, receptor complexes, which contributes to their binding to ligands, preservation of the structural and functional organization of biomembranes, transport of neurotransmitters and improve synaptic transmission.

Increases dopamine concentration in the brain. It enhances the compensatory activation of aerobic glycolysis and reduces the degree of inhibition of oxidative processes in the Krebs cycle under hypoxia with an increase in adenosine triphosphoric acid and creatine phosphate, activates the energy-synthesizing function of mitochondria.

Increases the body's resistance to various damaging factors in pathological conditions (shock, hypoxia and ischemia, cerebrovascular accident, intoxication with ethanol and antipsychotic drugs). Improves metabolism and blood supply to the brain, microcirculation and rheological properties of blood, reduces platelet aggregation.

Stabilizes the membrane of blood cells (red blood cells and platelets), reducing the likelihood of hemolysis. It has a lipid-lowering effect, reduces the content of total cholesterol and LDL. It normalizes metabolic processes in the ischemic myocardium, reduces the necrosis zone, restores and / or improves the electrical activity and contractility of the myocardium, and also increases coronary blood flow in the ischemic zone, increases the antianginal activity of nitro drugs, reduces the effects of reperfusion syndrome in acute coronary insufficiency.

Stress-protective effect is manifested in the normalization of post-stress behavior, somatovegetative disorders, restoration of sleep-wake cycles, impaired learning and memory processes, and reduction of dystrophic changes in various brain structures.

EMHPS has a pronounced antitoxic effect in withdrawal symptoms, eliminates neurological and neurotoxic manifestations of acute alcohol intoxication, and corrects behavioral and cognitive impairment. Under the influence of ethyl methyl hydroxypyridine succinate, the effect of tranquilizing, antipsychotic, antidepressant, hypnotics and anticonvulsants is enhanced, which allows to reduce their doses and reduce side effects.

Pharmacokinetics

Absorption

When i / m is administered, the drug is determined in blood plasma for 4 hours after administration. With a / m administration, Tmax in plasma is 0.3-0.58 hours. With a / m administration at a dose of 400-500 mg Cmax in plasma is 2.5-4 μg / ml.

Distribution of

EMHPS rapidly passes from the bloodstream to organs and tissues and is rapidly excreted. The average retention time of the drug in the body with i / m administration is 0.7-1.3 hours.

Metabolism and excretion

Metabolized in the liver by glucuronidation.

Rapidly excreted in the urine mainly in the form of metabolites (50% in 12 hours) and in insignificant amounts unchanged (0.3% in 12 hours). It is most intensely excreted during the first 4 hours after taking the drug. Urinary excretion rates of unchanged drug and metabolites have significant individual variability.

Doses are selected individually. The initial dose is 50-100 mg 1-3 times / day, which is gradually increased until a therapeutic effect is obtained.

Intravenously neurox is injected slowly for 5-7 minutes, drip at a speed of 40-60 drops / min.

The maximum daily dose is 800 mg.

In acute disorders of cerebral circulation, Neurox is used as part of complex therapy in the first 2-4 days iv in a drip of 200-300 mg 1 time / day, then - in / m 100 mg 3 times / day. The duration of treatment is 10-14 days.

In case of discirculatory encephalopathy in the decompensation phase, i.v. in a stream or drip at a dose of 100 mg 2-3 times / day for 14 days, then i / m at 100 mg / day for the next 14 days.

For the course of prophylaxis of discirculatory encephalopathy - i / m at a dose of 100 mg 2 times / day for 10-14 days.

In case of neurocirculatory dystonia, neurotic and neurosis-like conditions - i / m at 50-400 mg / day for 14 days.

With withdrawal alcohol syndrome - i / m in a dose of 100-200 mg 2-3 times / day or i / v drip 1-2 times / day for 5-7 days.

In acute intoxication with antipsychotic drugs - iv in a dose of 50-300 mg / day for 7-14 days.

Possibly: allergic reaction.

Drug Interaction

Enhances the action of benzodiazepine anxiolytics, antiepileptic (carbamazepine), antiparkinsonian (levodopa) drugs, nitrates.

Reduces toxic effects of ethanol.

Overdose

Symptoms: sleep disorder (insomnia, in some cases, drowsiness) with / in the introduction - a slight and short-term (up to 1.5–2 h) increase in blood pressure.

Treatment: usually not required - symptoms disappear on their own within a day. In severe cases, with insomnia - nitrazepam 10 mg, oxazepam 10 mg or diazepam 5 mg. In case of excessive elevation of blood pressure, hypotensive drugs are controlled by blood pressure.
