Mexicor®
Mexicor® has antioxidant, antihypoxic, membrane-protective, nootropic, stress-protective, anticonvulsant, and anxiolytic effects.
The drug increases the body's resistance to the effects of major damaging factors, to oxygen-dependent pathological conditions (shock, hypoxia and ischemia, cerebrovascular accident, intoxication with alcohol and antipsychotics (neuroleptics)).
The mechanism of action of Mexicor® is due to the antihypoxic, antioxidant and membrane-protective effects of ethylmethylhydroxypyridine succinate and succinic acid included in its composition.
The drug improves the functional state of ischemic myocardium during myocardial infarction, improves the contractile function of the heart, and also reduces the manifestations of systolic and diastolic dysfunction of the left ventricle.
The drug 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 its collateral blood supply, activating energy-synthesizing processes in the ischemic zone and helping to preserve the integrity of cardiomyocytes and maintain their functional activity.
Increases the antianginal activity of nitro drugs, improves the rheological properties of blood, reduces the consequences of reperfusion syndrome in acute coronary insufficiency.
The drug improves blood supply to the brain and cerebral metabolism, improves microcirculation and rheological properties of blood, and prevents a decrease in cerebral blood flow during the reperfusion period after ischemia. It has a hypolipidemic effect, reduces the content of total cholesterol and low-density lipoproteins. Mexicor® prevents a post-ischemic drop in the utilization of glucose and oxygen by the brain and prevents the progressive accumulation of lactate.
The drug inhibits the processes of lipid peroxidation, increases the activity of superoxide dismutase, increases the lipid-protein ratio, and improves the structure and function of the cell membrane. Modulates the activity of membrane-bound enzymes - calcium-independent phosphodiesterase, adenylate cyclase, acetylcholinesterase, receptor complexes (benzodiazepine, gamma-aminobutyric, acetylcholine), which enhances their ability to bind to ligands, helps preserve the structural and functional organization of biomembranes, transport of neurotransmitters and improve synaptic transmission. Mexicor® increases dopamine levels in the brain.
Mexicor® causes an increase in the compensatory activity of aerobic glycolysis and helps reduce the degree of inhibition of oxidative processes in the Krebs cycle under hypoxic conditions with an increase in the content of adenosine triphosphate (ATP), creatine phosphate and activation of the energy-synthesizing functions of mitochondria, stabilization of cell membranes.
Indications
In neurology, Mexidol is used in the following cases:
- acute cerebral circulatory disorders and discirculatory encephalopathy (otherwise – cerebral atherosclerosis);
- after transient ischemic attacks, in the subcompensation phase as preventive courses;
- vegetative-vascular dystonia;
- cognitive problems of atherosclerotic origin (impaired speech, memory, attention, intelligence and other symptoms associated with the development of atherosclerosis).
In psychiatry Mexidol is prescribed:
- to relieve withdrawal symptoms (otherwise known as withdrawal) due to alcohol and drug addiction;
- in case of intoxication with neuroleptics (drugs intended for the treatment of psychosis);
- to alleviate the impact of extreme (stress) factors;
- for anxiety disorders and neurotic and neurosis-like conditions.
Mexidol is also used for acute purulent-inflammatory processes of the peritoneum (necrotizing pancreatitis and peritonitis) as part of a complex of therapeutic treatments.
Analogs
The pharmaceutical market offers not only Mexidol, but also its analogues. The drugs differ in the main substance (although the synonyms of Mexidol still contain the same ethylmethylhydroxypyridine succinate), auxiliary components, manufacturers, and the quality of purification of the raw materials used. That is why, after consulting a doctor, you can select medications in pharmacies that are similar in their therapeutic effect to Mexidol tablets, but are suitable for a specific clinical picture.
Replacement of the drug with an analogue must be agreed with the attending physician
Mexidol analogue tablets include:
- Medomexy;
- Mexiprim;
- Mexidant;
- Mexipridol;
- Mexicofin;
- Neurox;
- Cerecard.
Analogues of Mexidol injections
In terms of therapeutic effect, the following drugs are similar to the solution:
- Medomexy;
- Armadin;
- Mexico;
- Astrox;
- Mexipridol;
- Mexiprim.
The therapeutic effect can be achieved by other active substances. But not always analogues in effect can ideally replace the drug chosen by the doctor, so replacement is possible only after consultation.
Thus, the following medications are considered analogous in effect:
- Kaviton (active ingredient - vinpocetine) improves metabolism in brain cells, helps improve blood circulation;
- Nootropil (active ingredient - piracetam) stimulates brain activity;
- Glycine (active ingredient - glycine) improves processes in the brain;
- Cytoflavin (active ingredient - succinic acid) stimulates brain activity, improves thought processes, etc.
Mexidol or Actovegin?
Often those who take Mexidol are faced with a choice between it and Actovegin. What's better? The drugs have similar uses and are often prescribed together. Both act on the central nervous system, eliminate hypoxia, restore metabolism and affect the circulatory system. But Mexidol has broader pharmacological properties, and it is used in most cases. Allergic reactions to Actovegin are more common, but it can be taken by pregnant women. Also, unlike Mexidol, Actovegin is used for disorders in peripheral vessels, and to treat the consequences of such disorders - trophic ulcers and angiopathy. As a result, the decision to prefer one of the drugs or take them together falls on the shoulders of the doctor.
How to take Mexidol?
Mexidol in tablet form is taken orally. The tablet is not chewed or divided in half. You should drink it with plenty of water. Eating does not have any effect on the activity of the medication, so you can take Mexidol before, during or after meals.
The injection form is used for intramuscular injections or intravenous infusions (stream or drip). Before giving the injection, the drug is diluted in a 0.9% sodium chloride solution. It is injected slowly in a stream over 5 - 7 minutes, drip - at a rate of 40 - 60 drops per minute. The maximum daily dose for tablets is 800 mg, for injections - 1200 mg. Course therapy is canceled gradually, after achieving a stable clinical and laboratory effect.
Mexidol solution for intravenous administration
Please note that drowsiness may occur after taking Mexidol, so you should be careful while driving, as well as when engaging in other potentially dangerous activities.

*When taking pills. The method of administering the Mexidol injection in the same dosage is indicated in parentheses.
The duration of therapy for patients with coronary heart disease is at least 1.5-2 months. It is advisable to carry out repeated courses (on the recommendation of a doctor) in the spring and autumn.
In case of acute myocardial infarction, as part of complex therapy, it is administered intravenously (the first 5 days) and intramuscularly (the next 9 days) for 14 days against the background of traditional therapy for myocardial infarction, including nitrates, beta-blockers, angiotensin-converting enzyme (ACE) inhibitors, thrombolytics, anticoagulants and antiplatelet agents, as well as symptomatic agents according to indications.
Side effects
One of the side effects after taking Mexidol may be nausea
Despite the body’s positive reaction to taking Mexidol and its low toxicity, the medicine still has side effects.
- from the cardiovascular system: increased blood pressure, decreased blood pressure;
- from the nervous system: drowsiness, difficulty falling asleep, anxiety, emotional reactivity, headache, loss of coordination;
- from the gastrointestinal tract: nausea, dry mouth;
- from the immune system: allergic reactions, including hyperemia, skin rash, itching;
- others: distal hyperhidrosis.
Interaction with other drugs
Mexidol has proven itself to be a drug that is highly compatible with other medications, including those used to treat somatic diseases. But it is worth noting that Mexidol can enhance the effect of benzodiazepines, carbamazepine and drugs for the treatment of Parkinson's disease, analgesics, tranquilizers, neuroleptics and antidepressants, as well as substances with hypnotics and anticonvulsants. This allows you to reduce their doses and remove most side effects.
Mexidol reduces the toxicity of ethyl alcohol. This beneficial property is used in the treatment of alcohol withdrawal syndrome.
Mexidol and alcohol
As mentioned above, Mexidol is used as therapy for getting rid of alcohol addiction. The drug reduces the toxic effect of alcohol and removes it from the body. But this does not mean that you can drink alcohol while taking Mexidol. The active substance Mexidol, penetrating into the tissues of the liver and brain, only stops the signs of intoxication, but does not protect the cells themselves. That is, the effect of alcohol consumed by Mexidol is not neutralized and causes harm to the body.
Mexidol during pregnancy and lactation
Often, medications for pregnant women and nursing mothers are prescribed with caution, and also in cases where the benefits to the mother outweigh the risks to the fetus and newborn. It’s the same story with Mexidol. There are no statistically reliable studies of the use of the drug in pregnant women, nursing mothers and children. That is, there are no clinical studies on which to rely, alas. Therefore, the drug is either prescribed as a last resort or is not recommended for use.
Mexidol is prescribed with caution during pregnancy
As for children, the use of Mexidol in pediatrics is indicated in the treatment of purulent neuroinfections, traumatic brain injuries, as well as for emergency care in case of childhood traumatic brain injuries (100 mg once).
