Pharmacological action:

The substance has antihypoxic, membrane-protective, nootropic, anticonvulsant, anxiolytic effect, increases the body’s resistance to stress. The drug increases the body’s resistance to the effects of major damaging factors, to oxygen-dependent pathological conditions (shock, hypoxia and ischemia, impaired cerebral circulation, intoxication with alcohol and antipsychotic drugs (neuroleptics)). Stabilizes membrane structures of blood cells (erythrocytes and platelets) in hemolysis.

Mexidol improves cerebral metabolism and blood supply to the brain, improves microcirculation and rheological properties of blood, reduces platelet aggregation. It has a hypolipidemic effect, reduces the level of total cholesterol and low-density lipoprotein (LDL).

Mexidol normalizes metabolic processes in ischemic myocardium, reduces the zone of necrosis, restores and improves the electrical activity and contractility of myocardium, and increases coronary blood flow in the zone of ischemia, reduces the effects of reperfusion syndrome in acute coronary insufficiency. Increases the antianginal activity of nitropreparations.

Mexidol promotes preservation of retinal ganglion cells and optic nerve fibers in progressive neuropathy, the causes of which are chronic ischemia and hypoxia. Improves the functional activity of the retina and optic nerve, increasing visual acuity.

Reduces enzymatic toxemia and endogenous intoxication in acute pancreatitis.

Pharmacodynamics:

The mechanism of action of the drug Mexidol is due to its antihypoxant, antioxidant and membrane-protective action. It inhibits lipid peroxidation processes, increases superoxide dismutase activity, increases lipid-protein ratio, decreases membrane viscosity, increases membrane fluidity. Modulates the activity of membrane-bound enzymes (calcium-independent phosphodiesterase, adenylate cyclase, acetylcholinesterase), receptor complexes (benzodiazepine, gamma-aminobutyric acid (GABA), acetylcholine), which enhances their ability to bind to ligands, helps to preserve the structural and functional organization of biomembranes, transport of neurotransmitters and improve synaptic transmission. Mexidol increases the content of dopamine in the brain. It enhances compensatory activity of aerobic glycolysis and decreases the degree of inhibition of oxidative processes in the Krebs cycle under hypoxia with an increase in adenosine triphosphate (ATP), creatine phosphate and activation of energy-synthesizing functions of mitochondria, stabilization of cell membranes.

Pharmacokinetics:

Absorption: When administered intramuscularly, it is detected in blood plasma within 4 h after administration. Time to reach maximum concentration Tmax is 0.45-0.5 h. Cmax at a dose of 400-500 mg is 3.5-4.0 µg/mL.

Distribution: Rapidly passes from the bloodstream to organs and tissues and is rapidly eliminated from the body. The time of retention of the drug (MRT) is 0.7-1.3 h.

Biotransformation: Metabolized in the liver by glucuron conjugation. Five metabolites have been identified: 3-oxypyridine phosphate – formed in the liver, breaks down into phosphoric acid and 3-oxypyridine with the participation of alkaline phosphatase; the 2nd metabolite is pharmacologically active, formed in large amounts and detected in the urine on 1-2 days after administration; the 3rd metabolite is excreted in large amounts with urine; the 4th and 5th metabolites are glucuronconjugates.

Elimination: The drug is excreted mainly with urine, mainly in the glucuronconjugated form and in minor amounts in unchanged form.

How to make Mexidol IM injection:

  1. Wash your hands thoroughly with soap and water and prepare the following items: medication prescribed by your doctor, a disposable syringe with a needle, alcohol wipes or alcohol solution with cotton pads.
  2. Choose the area to be injected. The most suitable injection site is upper outer square of the buttock or thigh.
  3. Open the ampoule and fill the syringe with the solution. Holding the syringe with the needle up, tap it with a finger to allow air bubbles to accumulate in the upper part, then remove the air by pressing the syringe plunger until drops of solution appear.
  4. Wipe the selected injection site an alcohol pad.
  5. Stretch the skin at the site of the injection. Introduce 2/3 of the needle at the angle of 90° (i.e., perpendicular) with a sharp and confident movement. Slowly press on the piston to inject the drug. After manipulation, it is necessary to clamp the puncture site with an alcohol wipe and massage a little.

In case of unpleasant symptoms that do not go away within a few minutes and may threaten your health/life, an ambulance should be called immediately!
