How does Corvalol work?


Considered medicinal product belongs to the group of combined, but all its components are optimally combined with each other, correcting the effect of each.

Ethyl bromizovalerate has sedative and antispasmodic effects. Phenobarbital, in turn, enhances the sedative effect of ethylbromoisovalerate, actively helps reduce the excitability and tension of the central nervous system, makes it possible to have a restful sleep. And peppermint oil has a complex effect on the human body: antispasmodic, choleretic, vasodilating, antiseptic. Therefore, peppermint oil helps to dilate blood vessels in the heart and brain, irritates the mucous membrane of the gastrointestinal tract - this restores intestinal motility and helps cope with increased gas formation.

It is not recommended to use the drug in question if the liver and kidney functions are severely impaired - for example, with renal failure, cirrhosis of the liver. But this issue is resolved on a strictly individual basis.

How to take Corvalol


The dosage, which will have the expected effect and will not cause harm to general health, should be determined only by a specialist and on an individual basis. But the instructions for using Corvalol also contain general recommendations according to its use:

  • adults can take 30 drops per dose; if tachycardia is diagnosed and with the approval of a doctor, the dosage can be increased to 40 drops per dose. You can take Corvalol 2-3 times a day;
  • Children over 3 years of age are prescribed 1 drop for each year of life once a day. In some cases, repeated administration of Corvalol is allowed, but a doctor must give permission for this.

The duration of the course of treatment is determined only by the doctor and prolonging it independently (“to consolidate the effect”) is strictly prohibited.

Side effects

Despite its apparent simplicity and safety, Corvalol can in some cases cause side effects. These include:

  • increased drowsiness;
  • constant dizziness;
  • the level of concentration decreases;
  • heart rate slows down.

Note: if taking Corvalol is carried out long time, then the so-called bromism phenomena may develop - addiction and drug dependence, “withdrawal” syndrome.

If the above side effects (or at least one of them) occur, you should immediately stop taking Corvalol and consult a doctor. Most likely, the treatment regimen will be adjusted or the dosage of the drug in question will be reduced.

Please note: in Corvalol contains phenobarbital and ethyl alcohol - these are substances that can affect the central nervous system. Therefore, when taking the drug in question, it is not recommended to drive vehicles or engage in work activities that require high concentration of attention.

Is Corvalol harmful?

The debate about how dangerous Corvalol is for human health has been going on relatively recently. Some time ago, many thought that Corvalol would be banned from sale in Russian Federation- it contains both phenobarbital and ethyl alcohol. But this turned out to be just rumors - such combination drugs remain on the market.

However, in most countries, Corvalol cannot be found in pharmacy chains - it has been withdrawn from sale without prescriptions. For example, the USA, Great Britain, Norway, Italy, the United Arab Emirates, Poland, Finland and Sweden have not only banned Corvalol for free sale, but also strictly control the transport of this drug across the border into the territory of their countries. Therefore, be extremely careful - if possible, then when visiting the listed countries, replace the drug; if this is not possible, the doctor prescribes it, then make sure you have a document confirming this fact. Otherwise, punishment will follow within the framework of the legislation of a particular country.

“Our population still has a very strong habit of using this drug. Radical measures - a ban on the sale of Corvalol, its withdrawal from consumption - will cause a negative reaction from patients. At the same time, Corvalol will gradually be replaced by other, more modern drugs with proven effectiveness,” the Russian Ministry of Health said in a statement.

Why is Corvalol so dangerous?

Firstly, phenobarbital, which is part of the drug in question, has been included in the group since 2013 psychotropic drugs. To be fair, we need to clarify that in many countries around the world this classification of phenobarbital has been accepted for a very long time.

Secondly, it is phenobarbital that causes rapid and strong addiction - in some cases, 2-3 weeks of taking the drug is enough to develop drug dependence. Moreover, phenobarbital causes not only physical, but also psychological dependence.

Thirdly, after stopping Corvalol, people develop the so-called “withdrawal” syndrome - a depressed state, the patient complains of constant nausea and intense headaches.

Interesting fact: Phenobarbital is used in some countries to carry out the death penalty.

But is there nothing useful in the remedy in question? After all, for a long time, Corvalol was recommended for use by millions of patients and in most cases, the course of therapy with the drug in question did not cause any consequences. Corvalol has one undeniable advantage - it has the fastest and most powerful effect.

If taken in small doses and extremely moderately, Corvalol can quickly, almost instantly, relieve anxiety. In general, the recommended doses of the drug are not dangerous, but the problem is that if you take it constantly, you will need to increase the dosage. The most dangerous thing is that these doses do not just increase each time, but lead to real pleasure: a depressed state and dizziness are replaced by euphoria immediately after taking the required dose.

The popularity of Corvalol is due to the fact that it is a cheap drug, known to everyone since ancient times and has a quick effect, but it should be used only when absolutely necessary or as prescribed by a specialist. If a person experiences any of the side effects listed in this article, or others notice sudden changes mood of someone who periodically uses Corvalol, then it is necessary to urgently seek medical care. The fact is that drug addiction needs to be treated only in specific medical institutions.

Pharmacological properties

Pharmacokinetics

When taken orally, absorption begins in the sublingual area, the bioavailability of the components is high (about 60-80%). The effect develops especially quickly (after 5-10 minutes) when held in the mouth (sublingual absorption) or taken on a piece of sugar. The action develops after 15-45 minutes and lasts for 3-6 hours. In individuals who have previously taken barbituric acid preparations, the duration of action is reduced due to accelerated metabolism of phenobarbital in the liver, where barbiturates cause enzyme induction. In elderly people and in patients with liver cirrhosis, the metabolism of Corvalol® is reduced, so their half-life is prolonged, which requires the need to reduce the dose and lengthen the intervals between doses of the drug.

Ethyl ester of α-bromoisovaleric acid has a reflex sedative and antispasmodic effect, caused primarily by irritation of the receptors of the oral cavity and nasopharynx, a decrease in reflex excitability in central departments nervous system and increased inhibition in the neurons of the cortex and subcortical structures of the brain, as well as a decrease in the activity of central vasomotor centers and a direct local antispasmodic effect on vascular smooth muscle.

Phenobarbital suppresses the activating influence of the centers of the reticular formation of the middle and medulla oblongata on the bark cerebral hemispheres, thereby reducing the flow of exciting influences on the cerebral cortex and subcortical structures. A decrease in activating influences causes, depending on the dose, sedative, tranquilizing or hypnotic effects. Corvalol® reduces the stimulating effects on the vasomotor centers, coronary and peripheral vessels, lowering total blood pressure, relieving and preventing vascular spasms, especially cardiac ones.

Peppermint oil contains a large number of essential oils, including about 50% menthol and 4-9% menthol esters. They are able to irritate the “cold” receptors of the oral cavity and reflexively dilate mainly the vessels of the heart and brain, relieving spasms of smooth muscles, causing a calming and mild choleretic effect. Peppermint oil has an antiseptic, antispasmodic effect, and the ability to eliminate flatulence. By irritating the receptors of the mucous membrane of the stomach and intestines, it enhances intestinal motility.

Indications for use

Neuroses with increased irritability

Insomnia

Vegetovascular dystonia

For functional disorders of the cardiovascular system (including tachycardia)

Intestinal spasms (as an antispasmodic)

Directions for use and doses

Corvalol® is taken orally, regardless of meals, 2-3 times a day, 15-30 drops with water (30-50 ml) or on a piece of sugar. If necessary (severe tachycardia), the single dose can be increased to 40-50 drops.

The duration of use of the drug is determined by the doctor depending on the clinical effect and tolerability of the drug.

Side effects

Discomfort in the stomach and intestines, nausea

Drowsiness, dizziness, decreased concentration

Allergic reactions

Slow heart rate

These phenomena are eliminated by reducing the dose.

With long-term use, dependence on the drug, withdrawal syndrome and bromism phenomena (suppression of the central nervous system, depression, apathy, rhinitis, conjunctivitis, acne, hemorrhagic diathesis, impaired coordination, confusion) are possible.

Contraindications

Hypersensitivity to the components of the drug, bromine

Severe liver and/or kidney dysfunction

Hepatic porphyria

Alcoholism

Traumatic brain injury or brain disease

Severe heart failure

Pregnancy and lactation

Children under 15 years old

Drug interactions

Drugs with central inhibitory action enhance the effect of Corvalol®. The presence of phenobarbital in the drug may induce liver enzymes, and this makes its simultaneous use with medications that are metabolized in the liver (coumarin derivatives, griseofulvin, glucocorticoids, oral contraception), since their effectiveness will decrease as a result of more high level metabolism. Corvalol® enhances the effect of local anesthetics, analgesics and hypnotics, this is due to the content of barbituric acid derivatives.

When used simultaneously with valproic acid, its effect is enhanced.

When used simultaneously with methotrexate, its toxic effect increases.

Alcohol enhances the effect of the drug and its toxicity.

special instructions

The simultaneous consumption of alcoholic beverages should be avoided.

The drug should be prescribed with caution in case of arterial hypotension.

Use in pediatrics

There is no experience of use for the treatment of children.

Use of the drug during pregnancy and lactation

Do not use during pregnancy and breastfeeding.

Features of the effect of the drug on the ability to drive vehicles or potentially dangerous mechanisms

The drug contains 58 vol.% alcohol, as well as phenobarbital, which can cause impairment of coordination and speed of psychomotor reactions, so when taking the drug you should refrain from driving vehicles and engaging in other potentially hazardous activities that require increased concentration and speed of psychomotor reactions.

When taking the drug Corvalol, instructions for use are necessary for mandatory study in order to determine possible action medications specifically for your body. High blood pressure usually develops over many years and eventually affects almost all people. After discovery high pressure control is possible with the help of doctors.

general characteristics

Corvalol is very useful drug, which dilates blood vessels, relieves convulsions of the venous vasculature and reduces pressure.

The role of neuropathic herbs that act as a complement to lowering high blood pressure is very high: chamomile, mint, anise and hibiscus. Corvalol contains these herbs in its ingredients.

At what pressure is Corvalol needed? They can mainly be taken for high blood pressure and rapid heartbeat and to calm the nervous system.

Sleep disorders, including cases of stress and psychological pressure, and stress - negatively affects life and imbalances arise in daily life.

Corvalol inhibits the action of adrenaline and slows the heartbeat and reduces the force of its contraction. Corvalol also relaxes blood vessels, increasing blood flow and lowering blood pressure.

For what symptoms should Corvalol be taken?

Corvalol lowers blood pressure by preventing the brain from transmitting nerve cells to the nervous system, which accelerate the heartbeat and constriction of blood vessels, thins the blood vessels by directly acting on the walls of blood vessels, preventing muscle contraction, and as a result of this prevention, the heart pumps less into the blood and facilitates blood flow in blood vessels.


More often symptoms of high blood pressure are:

  • Mild headaches.
  • Dizziness.
  • Bleeding from the nose.

Corvalol interferes with the sensory cortex, reduces heart activity and causes feelings of dizziness, drowsiness and hypnosis and acts as a convulsant when used in high doses. The treatment causes psychological and physical trauma, treatment is only considered by a specialist and is not recommended for long periods of time. The purpose of the drug Corvalol is purely individual and treats differently.

What doctors say about hypertension

Doctor medical sciences, Professor Emelyanov G.V.:

The next fact is that it is possible and necessary to reduce blood pressure, but this does not cure the disease itself. The only medicine that is officially recommended by the Ministry of Health for the treatment of hypertension and is also used by cardiologists in their work is. The drug acts on the cause of the disease, making it possible to completely get rid of hypertension. In addition, within the framework of the federal program, every resident of the Russian Federation can receive it FOR FREE.

Price for Corvalol

In Russia:


Corvalol in the form of release - tablets and drops - has a sedative, antiseptic, choleretic, vasodilating effect. The active component is phenobarbital, which irritates the cold receptors of the oral mucosa and gastrointestinal tract, dilates the blood vessels of the heart and brain, eliminates signs of flatulence, and enhances intestinal peristalsis.

Like any medicine, Corvalol has side effects, despite being sold in pharmacies without a doctor's prescription. Before using the tincture, it is important to read the instructions, take into account the indications, contraindications and side effects. It is best to consult your doctor first.

Side effects of Corvalol

The composition (drops, tablets) of Corvalol contains phenobarbital, which forms mental dependence if taken constantly and in large doses. In particular, the active ingredient is bromine, which in case of overdose leads to:

  • confusion;
  • impaired coordination of movements;
  • tendency to depression, panic attacks;
  • inhibition of central nervous system function;
  • dizziness;
  • drowsiness;
  • bradycardia;
  • nausea, vomiting;
  • stomach pain;
  • slowing heart rate;
  • allergies, skin rashes;
  • bowel disorder.

It is phenobarbital that is addictive due to constant, long-term use, so the effect as a sleeping pill will gradually decrease. But withdrawal syndrome in case of abrupt cessation of taking the drug may well lead to overexcitation, hallucinations, and excessive anxiety.

Long-term treatment with Corvalol leads not only to addiction, but also to the accumulation of metabolites in the body, the development of hypotension, and pulse disturbances, when in severe cases resuscitation and disinfection intoxication therapy are no longer necessary.

REFERENCE! Corvalol can sharply lower blood pressure, which is dangerous for hypertensive patients suffering from high performance HELL. It is not recommended to take the medicine together with other antiarrhythmic, antihypertensive, anticonvulsant, or steroid drugs. The effect may be unexpected and unfortunate.

Taking Corvalol with alcohol is incompatible, which will lead to toxic effects on the body, accumulation of ethanol in the blood, and side effects.

Side effects in children

According to the instructions, the use of the drug by children under 18 years of age is prohibited. Only in extreme cases is it possible for the attending physician to prescribe no more than 15 drops once a day, taking into account the weight and age of the child. In this case, the treatment process must be carried out under full control in order to avoid the negative impact of the alcohol-containing composition on the fragile child’s body.

It is forbidden for pregnant women to take Corvalol during lactation. The active component can have a teratogenic effect on the fetus and lead to congenital anomalies in the structure of internal organs and deformity of anatomical structures in infants at birth.

The medicine can have a negative impact on the development of the child and lead to suppression of the nervous system. In a baby in the first days of life, it can provoke increased bleeding.

If a pregnant mother abuses this drug in the 3rd trimester, then convulsions and excessive excitability in infants may occur in the first weeks of life. Women in an interesting situation are not recommended to take Corvalol in order to calm their nerves and it is better to give preference to other, safer and more effective sedatives.

Main side effects in children:

  • excessive excitability;
  • convulsions;
  • bleeding;
  • deterioration of blood clotting due to phenobarbital suppression of the nervous system.

Indications for use


Corvalol is a vasodilator, sedative and sedative. However, it cannot be considered a medicine, because it is impossible to cure any internal disease with just one drug. Corvalol helps minimize nervous disorders, but will not relieve renal colic, insomnia, and heart disease (myocardial infarction, angina). These are cheap drops indicated for use to minimize unpleasant symptoms or aid in addition to the main treatment. Main indications for use:

  • increased heart rate;
  • signs of tachycardia;
  • insomnia;
  • spasms of coronary vessels;
  • irritability;
  • hypertension at the initial stage;
  • vegetative-vascular dystonia for the purpose of complex therapy;
  • spasms in the intestines.

The drug will help you quickly calm down and fall asleep, but will not relieve severe neuroses or progressive depression.

IMPORTANT! Corvalol is not a cure for heart disease and will not help hypertensive patients normalize their blood pressure. The remedy can have only a temporary effect when discomfort appears in the heart area. This medicine is not prescribed as a drug for the treatment of diseases, therefore it is not recommended to abuse dosages and frequency of use.

Contraindications to the use of Corvalol


The drug is contraindicated if:

  • low blood pressure;
  • heart failure;
  • heart disease;
  • impaired renal and liver function;
  • individual intolerance;
  • allergy to lactose;
  • epilepsy;
  • traumatic brain injury;
  • convulsive syndrome;
  • alcohol addiction;
  • diabetes.

It is not advisable to take the medicine for children under 18 years of age and for pregnant women in the 1st trimester up to 12-14 weeks and in later stages. Also during lactation.

IMPORTANT! In case of heart failure, the medicine can cause myocardial infarction, so for hypertensive patients it is better to choose other drugs for treatment on the recommendation of a doctor.

Actions in case of overdose

If you still cannot avoid an overdose of Corvalol, then it is important to be able to provide timely first aid and eliminate signs of intoxication and remove toxic substances from the body. This means that you need to rinse your stomach, drink 2-3 glasses of clean water, take a sorbent (Smecta, Enterosgel, Filtrum, Activated carbon). You can press on the root of the tongue, thereby causing a gag reflex.

The main thing is to quickly remove excess Corvalol from the body. If lethargic sleep, coma, or convulsions occur, you should call an ambulance immediately.

Doctors evaluate cases of overdose as mild, moderate, or severe. If mild signs of poisoning appear: drowsiness, confusion, dizziness, apathy, headache and lethargy, it is important to stop taking the drug in time. If the patient continues to take Corvalol in increased doses, the condition may transition to moderate severity with the appearance of muscle spasms, convulsions, and vascular collapse. If poisoning progresses to a severe stage, the patient may fall into a coma, when there is a threat of death and if timely treatment is not provided emergency assistance, then everything could end badly.

INSTRUCTIONS

on medical use of the drug

Drops Corvalol

Composition of the drug:

active ingredients: ethyl ester of a-bromoisovaleric acid, phenobarbital, mint oil;

1 ml (26 drops) contains ethyl ester of a-bromoisovaleric acid in terms of 100% substance 20 mg, phenobarbital 18.26 mg, peppermint oil 1.42 mg;

Excipients: stabilizer, ethanol (96%), purified water.

Dosage form. Drops for oral use. Transparent colorless liquid with a specific odor.

Manufacturer's name and location.

JSC "Farmak"

Ukraine, 04080, Kyiv, st. Frunze, 63.

Pharmacotherapeutic group. Sleeping pills and sedatives. Combination drugs barbiturates. ATS code N05C B 02.

Corvalol drops are a sedative and antispasmodic, the effect of which is determined by the components included in its composition.

Ethyl ester of α-bromoisovaleric acid has a reflex calming and antispasmodic effect, caused by irritation mainly of the receptors of the oral cavity and nasopharynx, a decrease in reflex excitability in the central parts of the nervous system, increased inhibition in the neurons of the cortex and subcortical structures of the brain, as well as a decrease in the activity of the central vasomotor centers and direct local antispasmodic effect on smooth muscle vessels.

Phenobarbital suppresses the activating influences of the centers of the reticular formation of the midbrain and medulla oblongata on the cerebral cortex, thereby reducing the flow of exciting influences on the cerebral cortex and subcortical structures. A decrease in activating influences causes, depending on the dose, sedative, tranquilizing or hypnotic effects. Corvalol drops reduce the stimulating effects on the vascular motor centers, coronary and peripheral vessels, lowering total blood pressure, relieving and preventing vascular spasms, especially cardiac ones.

Peppermint oil contains a large amount of essential oils, including approximately 50% menthol and 4-9% menthol esters. They are able to irritate the “cold” receptors of the oral cavity and reflexively dilate mainly the vessels of the heart and brain, relieving spasms of smooth muscles, causing a calming and mild choleretic effect. Peppermint oil has antiseptic and antispasmodic effects, and the ability to eliminate flatulence. By irritating the receptors of the mucous membrane of the stomach and intestines, it enhances intestinal motility.

When taken orally, absorption begins in the sublingual area, the bioavailability of the components is high (approximately 60-80%). The effect develops especially quickly (after 5-10 minutes) when held in the mouth (sublingual absorption) or taken on a piece of sugar. The action develops after 15-45 minutes and lasts 3-6 hours. In individuals who have previously taken barbituric acid preparations, the duration of action is shortened due to accelerated metabolism of phenobarbital in the liver, where barbiturates cause enzyme induction. In elderly people and in patients with liver cirrhosis, the metabolism of Corvalol is reduced, so their half-life increases, which requires the need to reduce the dose and lengthen the intervals between doses of the drug.

Indications

Neuroses with increased irritability;

Insomnia;

In complex therapy hypertension and vegetative-vascular dystonia;

Mild spasms of the coronary vessels, tachycardia;

Intestinal spasms (as an antispasmodic drug).

Contraindications

Hypersensitivity to the components of the drug, bromine;

Severe liver and/or kidney dysfunction;

Hepatic porphyria;

Severe heart failure;

Pregnancy and breastfeeding.

Appropriate safety precautions for use.

The simultaneous consumption of alcoholic beverages should be avoided.

Use with caution in case of arterial hypotension.

Use during pregnancy or breastfeeding.

Do not use during pregnancy and breastfeeding.

The ability to influence the reaction speed when driving vehicles or other mechanisms.

The drug contains 58 vol. % Alcohol, as well as phenobarbital, which can cause impairment of coordination and speed of psychomotor reactions, so when taking the drug, people who work with machinery, drivers of vehicles, etc. should be careful.

Children. There is no experience of use in children.

Method of administration and dose.

Corvalol drops are taken orally, regardless of meals, 2-3 times a day, 15-30 drops with water or on a piece of sugar. If necessary (severe tachycardia and spasm of coronary vessels), the single dose can be increased to 40-50 drops.

The duration of use of the drug is determined by the doctor depending on the clinical effect and tolerability of the drug.

Overdose.

Overdose is possible with frequent or long-term use, which is associated with the accumulation of its components. Long-term and constant use can cause dependence, withdrawal syndrome, and psychomotor agitation. Sudden cessation of use may cause withdrawal symptoms.

Symptoms of overdose: central nervous system depression, confusion, dizziness, ataxia, drowsiness, even deep sleep. In severe cases of poisoning - respiratory failure, tachycardia, arrhythmia, decreased blood pressure, collapse, coma.

Treatment is symptomatic.

Side effects.

Corvalol drops are generally well tolerated. In some cases, the following side effects may occur:

- from the digestive system: discomfort in the stomach and intestines, nausea;

- from the nervous system: drowsiness, dizziness, decreased concentration;

- from the outside immune system: allergic reactions;

- from the cardiovascular system: slowing heart rate.

These manifestations are eliminated by reducing the dose.

With prolonged use, dependence on the drug and bromism may occur. Symptoms: depression of the central nervous system, depression, apathy, rhinitis, conjunctivitis, acne, hemorrhagic diathesis, loss of coordination, confusion.

Interaction with other drugs and other types of interactions.

Drugs with central inhibitory action enhance the effect of Corvalol. The presence of phenobarbital in the drug may induce liver enzymes, and this makes its simultaneous use with medications that are metabolized in the liver (coumarin derivatives, griseofulvin, corticosteroids, oral contraceptives) undesirable, since their effectiveness will be reduced as a result of a higher level of metabolism. Corvalol enhances the effect of local anesthetics, painkillers and hypnotics, this is due to the content of barbituric acid derivatives.

When used simultaneously with valproic acid, its effect is enhanced.

When used simultaneously with methotrexate, the toxicity of the latter increases.

Alcohol enhances the effect of the drug and also increases its toxicity.

Best before date. 2 years and 6 months.

Do not use after the expiration date stated on the package.

Storage conditions.

In a place protected from light at a temperature not exceeding 25 ° C.

Keep out of the reach of children.
