Manufacturer: GosZMP, FGUP (Russia)

Description and photo update: 2019-10-07

Astrox is an antioxidant agent.

Release form and composition

Dosage form - solution for intravenous (i / v) and intramuscular (i / m) administration: transparent, colorless or slightly tinged with a yellowish, brownish-yellowish or reddish tint (2 ml in an ampoule made of light-shielding glass with a dot or break ring, 5 ampoules in a blister contour packaging, in a cardboard box for consumer packaging, 2 packages and instructions for use of Astrox; for hospitals - in a cardboard box of 20, 50 or 100 packages).

Composition of 1 ml solution:

• active substance: ethylmethylhydroxypyridine succinate - 50 mg;
• auxiliary component: water for injection - up to 1 ml.

Pharmacological properties

Pharmacodynamics

Astrox, as an active ingredient, contains ethylmethylhydroxypyridine succinate, a drug belonging to the class of 3-hydroxypyridines that increases stress resistance, has antioxidant, nootropic, anxiolytic, antihypoxic, membrane-protective and anticonvulsant effects.

The drug improves the body's resistance to the effects of the main damaging factors, as well as to oxygen-dependent pathological conditions (cerebrovascular accident, hypoxia, ischemia, shock, intoxication with antipsychotic drugs and alcohol).

Astrox improves microcirculation, blood supply to the brain, cerebral metabolism and rheological properties of blood, reduces platelet aggregation. During hemolysis, it helps to stabilize the membrane structures of blood cells (erythrocytes and platelets). It has hypolipidemic properties, reduces the level of total cholesterol and low density lipoproteins. In acute pancreatitis, it reduces endogenous intoxication and enzymatic toxemia.

The mechanism of action of Astrox is explained by its antioxidant, antihypoxant and membrane-protective properties. Ethylmethylhydroxypyridine succinate inhibits lipid peroxidation processes, reduces membrane viscosity and increases its fluidity, increases superoxide dismutase activity and lipid-protein ratio. It modulates the activity of membrane-bound enzymes (acetylcholinesterase, adenylate cyclase and calcium-independent phosphodiesterase) and receptor complexes (benzodiazepine and acetylcholine, as well as gamma-aminobutyric acid), due to which their ability to bind to ligands is enhanced, the structure of the mediated membranous and functional organization of the biromo-functional organization of biroma

Astrox increases the amount of dopamine in the brain. Under conditions of hypoxia, it enhances the compensatory activity of aerobic glycolysis and reduces the degree of inhibition of oxidative processes in the Krebs cycle, which is accompanied by the activation of energy-synthesizing functions of mitochondria, an increase in the content of creatine phosphate and adenosine triphosphate (ATP), and stabilization of cell membranes.

The drug normalizes metabolic processes in the ischemic myocardium, restores and improves electrical activity and myocardial contractility, reduces the area of necrosis. In acute coronary insufficiency, it improves coronary blood flow in the ischemic zone and reduces the consequences of reperfusion syndrome. Strengthens the antianginal effect of nitrates.

With progressive neuropathy due to chronic ischemia and hypoxia, Astrox helps to preserve optic nerve fibers and retinal ganglion cells. Improves the functional activity of the optic nerve and retina, thereby increasing visual acuity.

Pharmacokinetics

With single and repeated use of Astrox, the pharmacokinetic characteristics of ethylmethylhydroxypyridine succinate do not differ significantly.

After the administration of Astrox at a dose of 400-500 mg, the maximum plasma concentration (C _max) is observed in about 0.58 hours and is 3.5-4 μg / ml.

Ethylmethylhydroxypyridine succinate is rapidly distributed in tissues and organs, the retention time of the drug (MRT) is 0.7,31.3 hours. In this case, the drug is rapidly excreted from the plasma and after 4 hours is almost undetectable in it.

The drug is metabolized in the liver by glucuronidation to form various metabolites. Five of them were identified: the first, 3-hydroxypyridine phosphate, is formed in the liver and, under the action of alkaline phosphatase, breaks down in the blood into 3-hydroxypyridine and phosphoric acid; the second - is pharmacologically active, is formed in large quantities, in the first 1-2 days after administration of the drug is found in urine; the third is excreted in large quantities in the urine; the fourth and fifth are glucuron conjugates.

The drug is excreted in the urine unchanged and in the form of glucuron conjugates.

Indications for use

Astrox is used in combination therapy for the following disorders / diseases:

• syndrome of autonomic (neurocirculatory) dystonia;
• anxiety disorders in neurotic and neurosis-like states;
• intellectual and mnestic disorders of various origins (including memory impairments in the elderly);
• acute violation of cerebral circulation;
• discirculatory encephalopathy (including atherosclerotic genesis);
• traumatic brain injury and its consequences;
• primary open-angle glaucoma of various stages;
• acute myocardial infarction (from the first day);
• acute intoxication with antipsychotic drugs;
• alcohol withdrawal syndrome with a predominance of vegetative-vascular and neurosis-like disorders in the clinical picture.

Contraindications

Absolute:

• acute renal / liver dysfunction;
• childhood;
• pregnancy and lactation;
• hypersensitivity to any component of the drug.

In patients with a history of allergic diseases, Astrox should be used with caution.

Astrox, instructions for use: method and dosage

Astrox solution is administered intravenously (drip or jet) and intramuscularly. The drug is administered intravenously in 0.9% sodium chloride solution; drip infusion rate - 40-60 drops / min, duration of jet injection - 5-7 minutes.

Depending on the indication, the maximum daily dose may be 1200 mg.

Recommended dosage regimens:

• acute disorders of cerebral circulation: the first 10-14 days - intravenous drip of 200-500 mg 2 to 4 times a day, in the next 14 days - intramuscularly 200-250 mg 2-3 times a day;
• syndrome of vegetative dystonia, neurotic and neurosis-like states: i.m. dose of 50-400 mg per day for 14 days;
• course prevention of encephalopathy in the stage of decompensation: the first 14 days - intravenous drip or jet, 200–500 mg 1–2 times a day, over the next 14 days - intramuscularly, 100–250 mg per day;
• intellectual-mnestic disorders: i / m, 100–300 mg per day for 14–30 days;

A single dose is 2–3 mg / kg of body weight (no more than 250 mg), a daily dose is 6–9 mg / kg (no more than 800 mg). The daily dose is divided into 3 administrations at 8 hour intervals.

* Intravenous administration is carried out by slow (in order to avoid the development of side effects) drop infusion, adding the drug to 100-150 ml of 0.9% sodium chloride solution or 5% dextrose (glucose) solution. The duration of the infusion is 30–90 minutes. If necessary, the drug is injected slowly in a stream for at least 5 minutes.

Side effects

• nervous system: drowsiness;
• gastrointestinal tract: dryness of the oral cavity, nausea, diarrhea;
• immune system: allergic reactions.

Overdose

Ethylmethylhydroxypyridine succinate is characterized by low toxicity, so Astrox overdose is unlikely. If the dose is accidentally exceeded, drowsiness may occur, sedation is possible. With the on / in the introduction, there is a slight and short-term (no more than 2 hours) increase in blood pressure.

In most cases, overdose treatment is not required, since the symptoms disappear on their own within 24 hours. If there is a marked increase in blood pressure, antihypertensive drugs may be recommended. For severe insomnia, use nitrazepam (10 mg), diazepam (5 mg), or oxazepam (10 mg).
