Pharmacological properties
Pharmacokinetics
After intravenous administration, the drug began to start quickly, and after intramuscular administration, the clinical effects in 8 hours. The effect of the drug prolonged and continues 17 to 28 days after intramusculosion and from 3 days to 3 weeks after local application (in the region proceedings). Dose of dexamethasone 0.75 mg is equivalent to a dose of 4 mg of methylprednisolonea of \u200b\u200btriamcinolone, 5 mg of prednisone and prednisolone, 20 mg of hydrocortisone and 25 MGCortizona. In the blood plasma, about 77% of dexamethasone binds to blood proteinamia, and mostly converted to albumin. Only minimality of dexamethasone binds to non-buminic proteins. Dexamethasone is a fat soluble compound. The drug is metabolized in the liver. Small quantities of dexamethasonmetabolized in the kidneys and other organs. The prevailing excretion occurred urine. The half-life (T1 \\ 2) is about 190 minutes.
Pharmacodynamics
Dexamethasone is the synthetic adrenal hormones (corticosteroid) with glucocorticoid effect. The drug translaimates a pronounced anti-inflammatory, anti-allergic and desensitizing effect, has immunosuppressive activity.
To date, adequateness of glucocorticoid mechanism has been accumulated, to submit, as it is on the cellular level. There are two clearly defined system-detectors detected in cytoplasm cells. By means of glucocorticoidreceptors, corticosteroids have anti-inflammatory immunosuppressive effects and regulate glucose homeostasis; Throughminexocuticoid receptors, they regulate sodium and potassium metabolism, and the water and electrolyte balance.

Method of application and dose
Doses are established individually for a fraction, depending on the nature of the disease, expected duration, tolerance of corticosteroids and the patient's reaction to the conductivity.
Parenteral application
The injection solution is administered intravenously or substitly, as well as in the form of intravenous injections (with glucose or physiological solution).
The recommended average initial dailyodosis during intravenous or intramuscular weight varies from 0.5 mg to 9 mg and, if necessary, more. The initial dose of dexamethasone needs to be applied to the dialect until the clinical effect is reached; Then the dose is gradually improved to the minimum efficient. During the day, it can be administered from 4 to 20 mg of dexamethasone 3-4 times. The duration of parenteral administration is usually available 3-4 days, then transfer to the supporting therapy of the oral formation of the drug.
Local administration
Recommended motherwise dose Dexamethasone fornutrisic administration ranges from 0.4 mg to 4 mg. Cooking can be repeated in 3-4 months. Injection in the same joint can only be carried out 3-4 times in life, and it is impossible to make injections more than two joints at the same time. More frequent administration of dexamethasone can be damaged by intra-articulate cartilage and bone necrosis. The dose depends on the check-out joint. The usual dose of dexamethasone is from 2 mg to 4 mg for large joints and from 0.8 mg to 1 mg for small joints.
The usual dose of dexamethasone for administration of the inbreaking bag is from 2 mg to 3 mg, for the introduction of a tendon, from 0.4 mg to 1 mg to the vagina, and for tendons - from 1 mg to 2 mg.
When introduced into limited foci, the same doses of dexamethazone are accustomed as used for intra-articular administration. The preparation can be administered simultaneously, maximum, in two hearths.
Dosing in children
In case of intramuscular administration, the dose of customize therapy is 0.02 mg / kg of body weight or 0.67 mg / m2 body area, which is divided into 3 injections with an interval of 2 days, or from0.008 mg to 0.01 mg / kg of body weight Or from 0.2 mg to 0.3 mg / m2 body area daily.

Medicinal interactions
The effectiveness of dexamethasone is reduced to the subproductive reception of rifampicin, carbamazepine, phenobarbitone, phenytoine (diphenylhydantoin), prison, ephedrine or aminogllutetimide. Dexamethasusnizes therapeutic effect hypoglycimizing drugs, hypotensiveces, prazicvantel and sodium fingers; Dexamethasone increases the activity of Geparyn, Albendazole and Kaliuretikov. Dexamethasone can change the number of cumarine-sized drugs.
The simultaneous use of dexamethasone of ibol doses of glucocorticoids or agonists B 2 receptors increases the risk of hypokalemia. Higher-humanity and toxicity of cardiac glycosides is noted in patients suffering from hypokalemia.
With the simultaneous use of oral administration, the half-life of glucocorticoids may increase, shifting to strengthening their action and increase the number of side effects.
It is contraindicated simultaneous use of the coderina and dexamethasone during the period of generic activity, since it can cause the death of a mother because of the edema of the lungs.
The simultaneous purpose of the dexamethasone of the Entoclopramid, diphenhydramine, strokerazine or 5-HT3 receptor antagonists (serotonin or 5-hydroxitripetamines (serotonin or 5-hydroxytripetrum yields 3), such as ondansetron or rivzetron, effectively for the production of nausea and vomiting caused by chemotherapy with the usesplain, cyclophosphamide, methotrexate, fluorouration.
special instructions
Application in pediatrics
In children during long-term treatment, it is necessary to carefully monitor the dynamics and development. In children during the growth period, glucocorticosteroids should only be based on vital testimony and under particularly careful observation. To prevent violation of growth processes with prolonged treatment of children under the age of 14, preferably every 3 days to make a 4-day break in treatment.
Children, during the treatment of patients who are in contacts, wind shelter, Specific immunoglobulins are prescribed.
With diabetes mellitus, tuberculosis, bacterial and amoebic dysentery, arterial hypertension, thromboembolism, cardiac and renal failure, non-specific ulcerative colitis, diverticulite, recently educated anastomose of the intestine, apply dexamethasone should be very careful and, subject to the possibility of adequate treatment for the disease. If the patient had a history of psychosis, then they are carried out with treatment only on life testimony.
With a sudden abolition of the drug, especially alluring the use of high doses, arises, the abolition of glucocorticosteroids: anorexia, nausea, inhibition, generalized muscular and skeletal pains, total weakness. After the discharge of the drug over several months, the relative failure of the adrenal cortex can be possible. If stressful situations arise into this period, it is prescribed temporarily glucocorticoids, and the adequateness of mineralocorticoids.
Before the use of the drug, it is desirable to examine the patient for the presence of a peptic pathology and intestinal tract. Patients with predisposition to the development of this datapactology must be appointed with preventive goal Antacid means.
During treatment with the drug, the patient must have a diet with rich in potassium, proteins, vitamins, with reduced fiv, carbohydrates and sodium.
In the presence of a patient in intercurentine applications, the septic state treatment with dexamethasone must be combined by centibacterial therapy.
If the treatment of dexamethasone is noted at 8 weeks to and 2 weeks after active immunization (vaccination), then in this case the effect of immunization will be reduced or completely neutralized.
Patients with severe acceleracy trauma violation of cerebral circulation on ischemic type prescribed glococorticoids are needed with caution.
Features of the influence on the ability to manage the intention or potentially hazardous mechanisms
Since dexamethasone can cause headproof and headache, when driving vehicles or work with snag mechanisms, it is recommended to refrain from driving the car of the orientation of other potentially hazardous mechanisms.
Overdose
Symptoms: It is possible to aggravate the effects.
For the treatment of many diseases sometimes apply hormonal drugs. They are synthetic analogues of hormones produced by adrenal glands. Typically, such drugs are easily associated with proteins and penetrate into the cells, so they quickly remove inflammation, pain, swelling, allergic reactions. One of the most common means that is used in emergency cases or in the composition complex therapyIs the drug dexamethasone. Its effectiveness is much higher than in some other hormonal means, and a low price makes treatment accessible to each patient. Despite the presence of a plurality of side effects, the injections of dexamethasone are used often, as they can significantly improve the condition of the patient or even save his life.
Dexamethasone refers to the group of glucocorticoid drugs. This is a synthetic hormone of adrenal cortex. The international non-proprietary name (short MNN) of his "dexamethasone", but it is possible to purchase a medicine with such a composition under the names of Dexazone, Metasic, Maxidge. These are all means from the glucocorticoid group. They are used in many pathologies, as they affect the organism at the cellular level.
Dexamethasone is the most popular tool from this group. The benefits of its relatives include a low price, a wide range of applications, the ability to use in the complex treatment of many diseases. In addition, its effectiveness is higher than from Cortisone 30 times. It costs this medicine cheap, the packaging price ranges from 35 to 100 rubles, depending on the form of release and dosage.
This drug is produced in ampoules, tablets and eye drops. In addition, it is added to some complex drugs for indoor and outdoor use. A solution for intravenous or intramuscular administration contains dexamethasone sodium phosphate, glycerin, phosphate diodriatium and water for injection.
Dexamethasone injections are made in cases where for some reason it is impossible to use tablets. Usually this heavy conditions, severe pains, serious allergic reactions. Injections are made no longer than 3-5 days, then if necessary, go to oral administration.
Dexamethasone is injected intravenously or intramuscularly. It depends on the age of the patient and the severity of its condition. It is very important that the use of this drug passes under the supervision of a doctor, as it is possible to develop serious side effects. Therefore, this medicine is sold in pharmacies only by recipe.
Dexamethasone is packaged in 1 ml ampoules. The solution is usually transparent, slightly yellowish. Each ampoule is 4 mg active substance. Packaging includes 10 or 20 ampoules embedded in contour cells, as well as instructions for use. Each ampoule usually has a sticker with the title. Sometimes they have a point or ring denoting the place of the break. Otherwise, a scarifier is attached to the packaging to laminating the tip of the ampoule.
Store dexamethasone is required in place inaccessible for children. This is not necessarily a refrigerator, the main thing is that the temperature does not exceed 25 degrees, but it is impossible to freeze the drug too. It is necessary to protect the solution from the effects of sun rays, so the ampoules should always be in a closed packaging. After opening, the storage solution is not subject to, it is impossible to use it anymore.
Important: It is also impossible to apply the drug that has an expiration date, tightness or storage conditions have been broken.
The use of dexamethasone injections is justified with many diseases. It is prescribed when other therapy turns out to be ineffective. This glucocorticoid is a popular tool due to strong anti-inflammatory, anti-stress and anti-shock action. In addition, it has the ability to remove allergic reactions, activate metabolic processes and reduce abnormal activity. immune system.
Frequently applies dexamethasone in ampoules, it is usually injected intramuscularly or intravenously
The effect of the drug at intramuscular administration occurs after 6-8 hours, so in emergency cases is usually administered intravenously. And if it is impossible to use the drug orally, it is injected into soft tissues. With this method of admission to the body, the active substance quickly reacts with proteins of cell receptors, which allows it to penetrate the kernel.
It turns out that the effect of the drug is manifested at the cellular level. This explains its effectiveness in many pathological conditions. Dexamethasone is able to adjust exchange processes. It oppresses the production of some enzymes that can slow down the metabolism or accelerate the splitting of proteins. Due to this, the state of cartilage tissue and bones is improved.
In addition, the use of dexamethasone reduces the activity of leukocytes and the immune system. This helps to reduce the inflammatory process in autoimmune pathologies. And thanks to a decrease in vessel permeability, this medicine prevents the spread of inflammation.
The injections of this drug are used only on life indications usually after another treatment has been tried, which turned out to be unsolved. Claims of dexamethasone doctors "ambulance" at a shock state, impaired adrenal operations, rapidly increasing brain edema, for example, after a crank-brain injury.
The testimony for such treatment includes brain tumors, meningitis, radiation damage. Apply drug after injuries, surgical operations, with tumors, allergies or inflammatory diseases of the joints.
The main indications of the use of dexamethasone are various articular diseases. Glucocorticoids are quickly removed inflammatory process and pain, so they are often prescribed when ordinary therapy does not bring positive results. And dexamethasone acts more efficiently than other drugs, so sometimes one injection is enough.
This drug improves the patient's condition when rheumatoid arthritis, diseases of Bekhtereva, sclerodermia, systemic red lolly, psoriasis. It accelerates recovery in various inflammatory diseases, for example, when ferursite, polyarthritis, epipidyl or synotte.
ATTENTION: Usually intramuscularly introduced it, but sometimes injections are made directly to the affected joint. In this case, you can repeat the injection only after 3 months. And you can enter from 0.4 to 4 mg.
Unacceptable long use Such injections or excess of the recommended dose. The active ingredient of this drug can negatively affect the state of cartilage tissues and even cause a weakening or breaking of tendons. Therefore, with such pathologies as osteoarthritis or osteochondrosis, it is rarely used and only under the supervision of a doctor.
Do not everyone know what dexamethasone prescribe, but many people suffering from allergies are familiar with him. This is one of the most common pathologies now. Typically, the correct behavior and the use of prescribed drugs makes it possible to normalize the state. But sometimes there are strong allergic reactions that can threaten health or even the life of the patient. Often in such cases, ordinary funds do not help remove strong edema or itching, so they are prescribed dexamethasone. It is able to quickly remove all the symptoms of allergies.
This drug is used most often in emergency cases: in the swelling of the quinque, angioedema edema or anaphylactic shock. But its use is also shown severe course Urban, dermatitis, eczema, conjunctivitis, half aulinosis. Usually, with these pathologies, it is recommended to prick dexamethasone for 4-8 mg 1-2 days. After removal acute symptoms It is better to go to the use of tablets.
This drug penetrates the bronchi and light, quickly removing swelling and inflammatory process. Therefore, it is often used in severe pathologies of respiratory organs, except for infectious. Dexamethasone is effective with asthmatic status, bronchial asthma or obstructive bronchitis. It significantly improves the patient's condition.
Such injections are used in emergency cases, for example, with a swelling of a quinque or bronchial asthma
This drug is especially used with similar pathologies. childhoodSince kids develop swells rapidly and respiratory function can be broken. Even acute laryngotrachite can give such complications, therefore comprehensive treatment Include glucocorticoid shots.
When appropriate, any drug is necessarily taken into account the presence of contraindications. This is especially important about dexamethasone. There are many pathologies in which it is impossible to apply the drug, as this may lead to the development of serious side effects.
ATTENTION: Such injections are not prescribed with some pathologies of the musculoskeletal system. Dexamethasone can slow down the processes of regeneration, as well as destroy the cartilage and bone tissue. High concentration It in the blood leads to the washing of calcium from the bones. Therefore, it is contraindicated to apply it during osteoporosis, the severe form of osteoarthrosis, after fractures.
It is very important not to apply such a medicine at various infectious diseases. Dexamethasone has an immunosuppressive effect, that is, inhibits immunity. If there are viruses, bacteria or fungi in the body, they begin to multiply quickly. Therefore, there are no such injections for tuberculosis.
In addition, such pathologies include contraindications:
Instructions for use necessarily warns of possible side effects. Dexamethasone penetrates the cells and changes the metabolic processes. When using it in large doses, the immune system is oppressed, violation fat Exchange, Washing out calcium from bone tissue and accumulating fluid in the intercellular space. Because of this, a person after a course of such therapy may develop serious infectious diseases, edema appear, fat deposits accumulate and the risk of fractures increases.
This drug has a lot of side effects, so it is trying to prescribe it in the lowest possible doses. But still, many patients after the course of dexamethazone injections are developing such pathologies:
Negative phenomena appear also at the injection site. It is often felt by pain, burning or numbness, a hematoma or a bump is formed. On the spot of the injection, the scar may appear, and skin covers are atrophy.
Injection use of glucocorticoids is possible only under the supervision of the doctor. In addition, the correct dosage is very important, there are certain rules for the introduction of such drugs. The main thing, dexamethasone needs to be introduced very slowly. Intravenous injections are better carried out in the form of a dropper. For this, the solution is diluted with glucose or sodium chloride. But with other drugs in one syringe mix this tool is prohibited.
It is desirable that the injection is done by a medical worker
But injections intramuscularly also need to do very slowly. With the rapid administration of the drug, it is possible to increase blood pressure and impairment of the heart.
Usually, the course of use of injections is 3-5 days. But it is not recommended to drastically discontinue treatment. Dexamethasone often leads to the development of cancellation syndrome, when the patient's condition of the patient is worsening after stopping the receipt of the medication into the body. Therefore, after the course of injection is transferred to the oral use of the drug. Moreover, its dosage gradually decreases under the guidance of the doctor.
Important: Prolonged use of glucocorticoids sometimes causes insufficiency of adrenal functions, which can manifest itself after a while after treatment.
In addition, large doses of dexamethasone lead to strong losses of potassium, which negatively affects the work of the heart muscle. Perhaps also development mental disorders, Therefore, it is sometimes recommended to introduce the necessary dose once a day in the morning.
In order for the treatment of dexamethasone to be effective, but the possibility of the appearance of side effects has decreased, it is important to introduce it in certain doses, which are usually defined individually, depending on the age of the patient, the severity of its condition and availability chronic pathologies. Adult patients at once are administered from 4 to 20 mg. Sometimes one injection is enough, since the effect of the drug is felt up to 3 weeks. But in severe cases, they make 3-4 injections per day. The maximum dosage per day is 80 mg.
The dosage of the dexamethasone solution depends not only on the individual characteristics of the patient, but also on the purpose of use. For example, at the edema of the brain, 16 mg of the drug is first introduced, the following injection is carried out after 6 hours, but already 5 mg. In such a dosage, injections are made every 6 hours.
Any medicine for women during a child tooling can be applied only according to the testimony of the doctor. And the dexamethasone solution easily penetrates through the placental barrier, as it acts at the cellular level. Therefore, the drug can negatively influence the child who has not yet born, causing various violations in its development. Then the baby may develop adrenal dysfunction.
This drug is used only when the state of a woman is severe and benefit from such treatment exceeds the risk of side effects.
Apply this tool from birth. Children make only intramuscular injections strictly according to the testimony of the doctor. The dosage at the same time should be calculated very carefully to prevent the appearance of side effects. Depending on the severity of the state, 0.2 to 0.4 mg is injected per kg of the child's weight. This is a daily dose that can be divided into 3-4 applications. It is advisable to use the minimum possible dosage and the duration of treatment.
Usually dexamethasone is used as part of a comprehensive treatment. But it is very important to take into account its compatibility with other medicines. Some of them can reduce the efficiency of the drug or increase the risk of development. side effects. It is unacceptable to engage in self-medication and you need to warn your doctor before the start of treatment about the medications taken.
It is impossible to take the drug in conjunction with other glucocorticoids or non-steroidal anti-inflammatory means. The risk of severe side effects also increases when using it together with contraceptives or ritodrine.
The solution of dexamethasone for injections is a fairly common means of treating various emergency states. Despite the possibility of the appearance of side effects, this drug is used quite often. But it is necessary to be prescribed by the doctor. The dosage is also selected individually. Failure to comply with medical recommendations during therapy may result in serious consequences.
Dexamethasone - hormonal medicinal substance For systemic use, the main active substance of which is a sodium dexamethasone phosphate.
It is used for disease therapy that can be influenced by glucocorticoids. The main form of release is injection solutions.
In this article, we will consider for what doctors prescribe the drug dexamethasone, including instructions for use, analogues and prices for this medicinal product in pharmacies. If you have already used dexamethazone, leave feedback in the comments.
List of components this drug Depends on the form in which it is produced. Dexamethasone comes in the pharmacy network as follows:
Clinical and Pharmacological Group: GCS for injections.
The use of dexamethasone is shown in replacement therapy of adrenal cortex deficiency, including acute or relative, primary and secondary, and also developed after the abolition of glucocorticosteroids (GKS).
According to the instructions, dexamethasone can also be included in the scheme of pathogenetic and symptomatic therapy at:
As part of combination therapy, dexamethasone is used with a shock of different genes. In combination with antimicrobial agents, the drug is often used in infectious diseases.
Dexamethasone - a powerful immunosuppressant, has an anti-inflammatory and antiallergic effect. In the presence of an active substance, the receptor sensitivity of β-adrenoreceptors to the adrenaline and noraderennaline produced by the brain layer of adrenal glands is enhanced.
One ampoule of dexamethasone causes the oppression of the operation of the hypothalamic-pituitary-glkocortical system for 3 days. In an equivalent ratio of 0.5 mg of dexamethasone correspond to the action of 3.5 mg of prednisolone, 15 mg of hydrocortisone or 17.5 mg of cortisone.
Dosing mode is individual and depends on the indications, the state of the patient and its reaction to therapy. The drug is introduced into / in slowly inkjet or drip (with sharp and urgent states); per / m; Local (in pathological education) is also possible. In order to prepare a solution for in / in drip infusion, an isotonic solution of sodium chloride or a 5% solution of dextrose should be used.
In the acute period of the disease and at the beginning of treatment, the drug is used in higher doses. When the effect is reached, the dosage decreases with an interval of several days before the maintenance dose is achieved or before discontinuation of treatment. Dosing mode individual.
The drug is contraindicated in individual intolerance and severe hepatic insufficiency. With extreme caution and emergency control of the attending physician, the drug dexamethasone is introduced to women in pregnancy, children and adults with:
The frequency of development and severity of side effects depend on the duration of use, the value of the dose used and the possibility of compliance with the circadian rhythm of the destination. Usually dexamethasone is well tolerated. As a rule, low and medium doses of dexamethasone do not cause sodium delays and water in the body, an increased excretion of potassium.
Nevertheless, such side effects are possible:
Symptoms: In the case of the use of the drug in high doses for several weeks, the majority of the side effects listed above the side effects and syndrome of Cushing is possible.
Treatment: a reduction in the dose or temporary cancellation of the drug, the conduct of symptomatic therapy. There is no special antidote. Hemodialysis is not effective.
During pregnancy (especially in the first trimester) the drug can be applied only when the expected therapeutic effect Exceeds the potential risk to the fetus. With long-term therapy during pregnancy, the possibility of breach of fetal growth is not excluded. In the case of use at the end of pregnancy, there is a danger of atrophy of the adrenal cortex at the fetus, which may require substitution therapy in a newborn.
If it is necessary to carry out treatment with a drug during breastfeeding, then breastfeeding should be stopped.
Currently, there are a large number of dexamethasone substitutes. This is Dexazazone, Decamed, Dexapos, Deckon D, Maxidge, Forthetortin, Dexafar and many others. In this case, dexametosone has a tangible price advantage.
The average price of dexamethasone injections in pharmacies (Moscow) 138 rubles.
List B. Store at a temperature not higher than 25 ° C in an inaccessible place for children. Do not freeze. Shelf life - 3 years. Do not apply after the expiration date indicated on the package.
Dexamethasone instructions for use (injections in ampoules, eye drops, pills). DexameThasone is a powerful synthetic glucocorticoid (containing adrenal cortex hormones and their synthetic analogs) with a drug intended for the regulation of protein, carbohydrate and mineral exchange.
Dexamethasone instructions for use, reviews, analogues and forms of release (0.5 mg tablets, injections in ampoules (injection solution), drops of eye offang) medicines for the treatment of inflammation in adults, children and during pregnancy.
The oral use of dexamethasone in the form of tablets implies the prescription of 10-15 mg of the drug per day at the initial stage of treatment, followed by a decrease in the daily dose to 2-4.5 mg with supporting therapy. Daily dose of the drug dexamethasone instruction recommends dividing 2-3 receptions (after or during meals).
Supporting small doses should be taken once a day, preferably in the morning. Dexamethasone in ampoules is designed for intravenous (drip or inkjano), intramuscular, perarticular and intra-articular administration. Recommended daily dose of dexamethasone with such methods of administration - 4-20 mg. Dexamethasone in ampoules is usually used 3-4 times a day for 3-4 days, followed by the transition to the tablet.
Dexamethasone drops are used in ophthalmology: with acute states of 1-2 drops of the drug, they are injected into a conjunctival bag every 1-2 hours, while improving the state - every 4-6 hours. Chronic processes involve the use of dexamethasone drops 2 times a day.
The duration of treatment depends on clinical flow Diseases, therefore, dexamethasone drops can be used from several days to four weeks.
Diseases requiring the introduction of high-speed GCS, as well as cases where oral administration is impossible:
For short-term use on life indications, the only contraindication is increased sensitivity to dexamethane or components of the drug.
In children during the growth period, GCS should be applied only in absolute indications and under particularly thorough observation of the attending physician.
Carefully The drug should be prescribed under the following diseases and states:
Therapeutic and toxic effects of dexamethasone reduce barbiturates, phenytoin, rifabutin, carbamazepine, ephedrine and aminoglutetimide, rifampicin (accelerate metabolism); somatotropin; Antacids (reduce suction), reinforce - estrogen-containing oral contraceptives. Simultaneous use with cyclosporin increases the risk of savoring in children.
The risk of arrhythmias and hypokalemia increases cardiac glycosides and diuretics, the likelihood of edema and arterial hypertension - sodium-containing drugs and nutritional supplements, heavy hypokalemia, heart failure and osteoporosis - amphotericin in and carbonic henching inhibitors; The risk of erosive-ulcerative lesions and bleeding from the gastrointestinal tract - non-steroidal anti-inflammatory means. Dexamethasone instructions for use.
With simultaneous use with alive antiviral vaccines and against the background of other types of immunization, increases the risk of activation of viruses and the development of infection.
Simultaneous use with thiazide diuretics, furosemide, etcrinic acid, carboanhydrase inhibitors, amphotericin B can lead to severe hypokalemia, which can enhance the toxic effects of cardiac glycosides and non-polarizing muscle relaxants.
Weakens the hypoglycemic activity of insulin and oral antidiabetic agents; anticoagulant - kumarins; Diuretic - diuretic diuretics; Immunotropic - vaccination (suppresses antibody).
It worsens the tolerance of cardiac glycosides (causes potassium deficiency), reduces the concentration of salicylates and the prazicvantel in the blood. It may increase blood glucose concentration, which requires a dose correction of hypoglycemic drugs, sulfonylurea derivatives, asparaginases.
GCS increases the clearance of salicylate, so after the cancellation of dexamethasone, it is necessary to reduce the dose of salicylate. With simultaneous use with an indomethacin, a dexamethasone suppression test may produce false-negative results.
Designed for intravenous, intramuscular, intra-articular, periarticular and retrobulbar administration. Dosing mode is individual and depends on the indications, the state of the patient and its reaction to therapy.
In order to prepare for a / in drip infusion, an isotonic solution of sodium chloride or a 5% dextrose solution should be used. The introduction of high doses of dexamethasone can be continued only before stabilizing the patient's condition, which usually does not exceed 48 to 72 hours.
Adults in acute and urgent states are introduced into / in slowly, inkidino or drip, or in / m in a dose of 4-20 mg 3-4 times a day. Maximum single dose -80 mg. Supporting dose - 0.2-9 mg per day. The course of treatment is 3-4 days, then go to oral administration of dexamethasone. Children - in / m in a dose of 0.02776-0.16665 mg / kg every 12-24 hours.
The drug is prescribed again with an interval from 3 days to 3 weeks as needed; maximum dose For adults - 80 mg per day. With a shock, adults - in / in 20 mg once, then according to 3 mg / kg for 24 hours in the form of a continuous infusion or to / in one-time 2-6 mg / kg, or in / in 40 mg each 2- 6 o'clock.
At the edema of the brain (adults) - 10 mg in / c, then 4 mg every 6 hours per / m to eliminate symptoms; The dose is reduced after 2-4 days and gradually - for 5-7 days - cease treatment. In case of insufficiency of the adrenal corthes (children) in terms of 0.0233 mg / kg (0.67 / mg / m2) per day in 3 injections every third 24 hours, or daily at 0.00776-0.01165 mg / kg ( 0.233- 0.335 mg / m2) per day.
With acute allergic reaction or exacerbation of chronic allergic disease, dexamethasone must be assigned to the following graph, taking into account the combination of parenteral and oral application: Dexamethasone Instructions for use The injection solution 4 mg / ml: 1 day, 1 or 2 ml (4 or 8 mg) intramuscularly; Dexamethasone Tablets 0.75 mg: second and third days, 4 pieces in 2 receptions per day, fourth - 2 pieces in 2 reception, fifth and sixth days - 1 pcs. Daily, on the seventh - without treatment, 8 day-observation.
Usually dexamethasone instructions for use are well tolerated. It has low mineralocorticoid activity, i.e. His influence on water-electrolyte exchange Nightly. As a rule, low and medium doses of dexamethasone do not cause sodium delays and water in the body, an increased excretion of potassium.
The following side effects are described:
Allergic reactions: Skin rash, itching, anaphylactic shock, local allergic reactions.
Local with parenteral administration: burning, numbness, pain, tingling and infection at the injection site, rarely - necrosis of the surrounding tissues, the formation of scars; Atrophy of the skin and subcutaneous tissue at a per / m administration (it is especially dangerous to prick in the deltoid muscle).
Others: Development or aggravation of infections (the appearance of this by-effect The jointly used immunosuppressants and vaccination), leukocyturia, "rings" of blood to the face, "Cancellation" syndrome are promoted.

GKS for injection
Dexamethasone phosphate (in shape sodium salt) (DexameThasone)
Injection Transparent, colorless or pale yellow.
Auxiliary substances: methylparaben, propylparaben, sodium metabisulfite, Dinatari Edetat, sodium hydroxide, water d / and.
2 ml - dark glass ampoules (25) - cardboard boxes.
2 ml - dark glass vials (25) - cardboard boxes.
Synthetic glucocorticoid (GKS), methylated fluoroprednisolone derivative. It has an anti-inflammatory, immunosuppressive effect, increases the sensitivity of beta-adrenoreceptors to endogenous catecholaminam.
Interact with specific cytoplasmic receptors (receptors for GCS are in all tissues, especially there are many of them in the liver) with the formation of a complex inducing proteins (including enzymes that regulate vital processes in cells.)
Protein exchange: Reduces the number of globulins B, increases the synthesis of albumin on the liver and kidney (with an increase in albumin / globulin coefficient), reduces the synthesis and enhances the catabolism of the protein in muscle tissue.
Lipid exchange: increases the synthesis of higher fatty acids and triglycerides, redistribute fat (the accumulation of fat occurs mainly in the field of shoulder belt, facial, abdomen), leads to the development of hypercholesterolemia.
Carbohydrate: Increases carbohydrate absorption from the gastrointestinal tract; increases the activity of glucose-6-phosphatase (increasing the flow from the liver into blood); Increases the activity of phosphoenolpiruwatkarboxylase and the synthesis of aminotransferase (activation of gluconeogenesis); Promotes the development of hyperglycemia.
Water-electrolyte exchange: delays Na + and water in the body, stimulates the removal of K + (mineralocorticoid activity), reduces the absorption of Ca + from the gastrointestinal tract, reduces the mineralization of bone tissue.
The anti-inflammatory effect is associated with the oppression of release of eosinophils and fat cells of inflammation mediators; induction of lipocortion formation and reducing the number of fat cells producing hyaluronic acid; with a decrease in permeability of capillaries; Stabilization of cell membranes (especially lysosomal) and organelle membranes. Acts on all stages of the inflammatory process: inhibits the synthesis of prostaglandins (PG) at the level of arachidonic acid (lipocortine inhibits phospholipase A2, suppresses the liberation of arachidonic acid and inhibits the biosynthesis of endoperosis, leukotrienes, contributing to the processes of inflammation, allergies, etc.), synthesis of "pro-inflammatory cytokines" ( Interleukin 1, factor of necrosis of the Alpha tumor, etc.); Increases the stability of the cell membrane to the action of various damaging factors.
The immunosuppressive effect is due to the resulting lymphoid tissue involution, the inhibition of lymphocyte proliferation (especially T-lymphocytes), suppressing the migration of B cells and the interaction of T- and limfocytes, the braking of the release of cytokines (interleukin-1, 2; gamma interferon) from lymphocytes and macrophages and a decrease in antibody formation.
The antiallergic effect develops as a result of a decrease in the synthesis and secretion of allergy mediators, inhibition of release of the release of sensitized fat cells and basophils of histamine and other biologically active substances, reducing the number of circulating basophils, t- and deformphocytes, fat cells; suppressing the development of lymphoid and connective tissue, reducing the sensitivity of effector cells to allergy mediators, inhibition of antibody formation, changes in the immune response of the body.
With obstructive diseases of the respiratory tract, the action is due mainly to the braking of inflammatory processes, the prevention or decrease in the severity of edema of mucous membranes, a decrease in the eosinophilic infiltration of the submembrance layer of the epithelium of the bronchi and sediments in the mucous membranes of the circulating immune complexes, as well as the braking of erosion and deskvamation of the mucous membrane. Increases the sensitivity of beta-adrenoreceptors of bronchi small and medium caliber to endogenous catecholamps and exogenous sympathomimetics, reduces the viscosity of the mucus by reducing its products.
Suppresses the synthesis and secretion of ACTH and the secondary - synthesis of endogenous GKS.
Inhibits the connective tissue reactions during the inflammatory process and reduces the possibility of forming scar tissue.
Action feature is a significant inhibition of the pituitary function and almost complete absence of mineralocorticosteroid activity.
Doses 1-1.5 mg / day depress the function of the adrenal cortex; The biological half-life - 32-72 h (the duration of the oppression of the hypothalamus-pituitary-hypophy-cortical substance of the adrenal glands).
Approximately 3.5 mg of prednisone (or), 15 mg of hydrocortisone or 17.5 mg of cortisone correspond to 0.5 mg of dexamethasone.
Blood binds (60-70%) with a specific protein-transceiver - transcertine. Easily passes through histohematic barriers (including through hematophephalic and placental).
Metabolized in the liver (mainly by conjugation with glucuronic and sulfuric acids) to inactive metabolites.
Excreted by kidneys (small part - lactating glands). T 1/2 dexamethasone from plasma - 3-5 h.

Dosing mode is individual and depends on the indications, the state of the patient and its reaction to therapy. The drug is introduced into / in slowly inkjet or drip (with acute and urgent states); per / m; Local (in pathological education) is also possible. In order to prepare a solution for in / in drip infusion, an isotonic solution should be used or a 5% dextrose solution.
In the acute period various diseases And at the beginning of therapy, dexamethasone is used in higher doses. During the day, you can enter from 4 to 20 mg of dexamethasone 3-4 times.
Dose drug for children (in / m):
The dose of the drug during substitution therapy (in case of insufficiency of the adrenal cortex) is 0.0233 mg / kg of body weight or 0.67 mg / m 2 of the body surface area, divided by 3 doses, every 3rd day or 0.00776 - 0.01165 mg / kg body weight or 0.233 - 0.335 mg / m 2 body surface area daily. With other indications, the recommended dose is from 0.02776 to 0.16665 mg / kg of body weight or 0.833 - 5 mg / m 2 of the body surface area every 12-24 hours.
When the effect is reached, the dose is reduced to supporting or before discontinuation. The duration of parenteral use is usually 3-4 days, then go to the supporting therapy with dexamethasone in tablets.
The long-term use of high doses of the drug requires a gradual reduction in the dose in order to prevent the development of acute insufficiency of adrenal cortex.
Usually dexamethasone is well tolerated. It has low mineralocorticoid activity, i.e. Its influence on water-electrolyte exchange is small. As a rule, low and medium doses of dexamethasone do not cause sodium delays and water in the body, an increased excretion of potassium. The following side effects are described:
From the endocrine system:reducing glucose tolerance, steroid diabetes or manifestation of latent diabetes mellitus, inhibition of adrenal functions, Izsenko-Cushing syndrome (moon-like face, hypophized type obesity, girsutism, enhancement of blood pressure, dysmenorrhea, amenorrhea, muscle weakness, strry), latency of sexual development Children.
From the digestive system:nausea, vomiting, pancreatitis, steroid ulcer of the stomach and duodenum, erosive esophagitis, gastrointestinal bleeding and perforation of the walls of the gastrointestinal tract, an increase or decrease in appetite, disruption of digestion, flatulence, ICOT. In rare cases - an increase in the activity of hepatic transaminases and alkaline phosphatase.
From the side of the cardiovascular system:arrhythmias, bradycardia (up to a heart stop); Development (in predisposed patients) or strengthening the severity of heart failure, changes on the electrocardiogram characteristic of hypokalemia, an increase in blood pressure, hypercoagulation, thrombosis. In patients with acute and subacted myocardial infarction - the spread of the focus of necrosis, slowing down the formation of scar tissue, which can lead to the rupture of the heart muscle.
From the nervous system:delium, disorientation, euphoria, hallucinations, manic-depressive psychosis, depression, paranoia, increasing intracranial pressure, nervousness or anxiety, insomnia, dizziness, vertigo, pseudogo cerebellum, headache, convulsions.
From the senses:rear subcapsular cataract, an increase in intraocular pressure with possible damage to the optic nerve, a tendency to the development of secondary bacterial, fungal or viral eye infections, trophic changes of the cornea, exophthalm, sudden loss of vision (with parenteral administration in the head, neck, nasal shells, the skin of the head is possible Deposition of drug crystals in eye vessels).
From the metabolism:increased excretion of calcium, hypocalcemia, body weight increase, negative nitrate balance (increased protein decay), increased sweating.
Conditioned mineralocorticoid activity- Liquid delay and sodium (peripheral edema), plasternatrhythmia, hypocalaminessindrome (hypokalemia, arrhythmia, myalgia or muscle spasm, unusual weakness and fatigue).
From the musculoskeletal system:the slowdown in the growth and processes of ossification in children (premature closure of epiphyseal growth zones), osteoporosis (very rarely pathological fractures of bones, aseptic necrosis of the head of the shoulder and femur), the gap of the muscle tendons, steroid myopathy, a decrease in muscle mass (atrophy).
From the side of the skin and mucous membranes:slowed healing of wounds, petechia, ekkimosis, skin thinning, hyper- or hypopigmentation, steroid eels, strry, tendency to the development of pyodermia and candidiasis.
Allergic reactions:skin rash, itching, anaphylactic shock, local allergic reactions.
Local with parenteral administration:burning, numbness, pain, tingling at the place of administration, infection at the injection site, rarely - necrosis of the surrounding tissues, the formation of scars at the injection site; Atrophy of the skin and subcutaneous tissue at a per / m administration (the introduction into the deltoid muscle is especially dangerous).
Others:the development or aggravation of infections (jointly used immunosuppressants and vaccination and vaccination), leukocyturia, "tides" of blood to the face, "cancellation" syndrome contribute to the appearance of this side effect.
It is possible to strengthen the side phenomena described above.
It is necessary to reduce the dose of dexamethasone. Treatment is symptomatic.
Pharmaceutical incompatibility of dexamethasone with others in / in the injected drugs is possible - it is recommended to be administered separately from other drugs (in / in bolus, or through Dr. dropper, as a second solution). When mixing a solution of dexamethasone, a sediment is formed with heparin.
Simultaneous purpose of dexamethasone C:
- Inductors of hepatic microsomal enzymes(phenobarbital, rifampicin, phenytoin, theophylline, ephedrine) leads to a decrease in its concentration;
— diuretics(especially tiazide and carboanhydrase inhibitors) and amphotericin in - It may lead to an increase in the elimination of the K + organism and an increase in the risk of developing heart failure;
— with sodium-containing drugs- to the development of edema and an increase in blood pressure;
— cardiac glycosides -their portability deteriorates and the likelihood of the development of ventricular extrasytoly increases (due to the caused hypokalemia);
— indirect anticoaguppy- weakens (less often enhanced) their action (dose correction is required);
— anticoagulants and thrombolitics -rises the risk of developing bleeding from ulcers in the gastrointestinal tract;
— ethanol and npvp - the risk of erosive-ulcer lesions in the gastrointestinal tract and the development of bleeding is increasing (in combination with NSAIDs in the treatment of arthritis it is possible to reduce the dose of glucocorticosteroids due to the summation of the therapeutic effect);
— paracetamol- the risk of hepatotoxicity is increasing (induction of hepatic enzymes and the formation of toxic paracetamol metabolite);
— - accelerates its elimination and reduces blood concentration (when dexamethasone cancels, the level of salicylates in the blood increases and the risk of developing side effects) is increasing);
— insulin and oral hypoglycemic drugs, hypotensive means -their effectiveness decreases;
— vitamin D -it decreases its effect on the suction of CA 2+ in the intestine;
— somatotropic hormone -reduces the effectiveness of the latter, and with praziquantel -its concentration;
— M-cholinoblocators(including antihistamines and tricyclic antidepressants) and nitrates -contributes to an increase in intraocular pressure;
— isoniazid and Mexylethine- increases their metabolism (especially in "slow" acetylastors), which leads to a decrease in their plasma concentrations.
Carboangeerase and "loop" diuretics inhibitors can increase the risk of osteoporosis.
Indomethacin, ousting dexamethasone due to albumin, increases the risk of developing its side effects.
ACTH enhances dexamethasone action.
Ergocalciferol and pararathgamon prevent the development of osteopathy caused by dexamethasone.
Cyclosporine and ketoconazole, slowing down dexamethasone metabolism, can in some cases increase its toxicity.
The simultaneous purpose of androgens and steroidal anabolic preparations with dexamethasone contributes to the development of peripheral edema and girsutism, the appearance of acne.
Estrogens and oral estrogen-containing contraceptives reduce dexamethasone clearance, which can be accompanied by an increase in the severity of its action.
Mitanka and other inhibitors of the adrenal cortex functions can determine the need to increase the dose of dexamethasone.
With simultaneous use with alive antiviral vaccines and against the background of other types of immunization increases the risk of activating viruses and the development of infections.
Antipsychotic means (neuroleptics) and azathioprine increase the risk of cataracts when appointing dexamethasone.
With simultaneous use with antihydride preparations, decreases, and with thyroid hormones - the clearance of dexamethasone increases.
During treatment with dexamethasone (especially long), observation of the eyepiece, control of the blood pressure and state of the water and electrolyte balance, as well as the pattern of peripheral blood and blood glucose levels is necessary.
In order to reduce side effects, antacids can be prescribed, and also to increase the admission to + in the body (diet, potassium preparations). Food should be rich in squirrels, vitamins, with limiting the content of fats, carbohydrates and cooking salts.
The effect of the drug is enhanced in patients with hypothyroidism and cirrhosis of the liver. The drug can strengthen existing emotional instability or psychotic disorders. When specifying psychosis, a history of dexamethasone in high doses is prescribed under the strict control of the doctor.
With caution, it should be used in acute and subacted myocardial infarction - it is possible to spread the focus of necrosis, slowing down the formation of scar tissue and the gap of the heart muscle.
In stressful situations during supportive treatment (for example, surgical operations, injury or infectious diseases), a dose correction should be corrected due to the increase in glucocorticosteroid need. It should be carefully observed for patients during the year after the end of long-term therapy with dexamethasone due to the possible development of the relative failure of the adrenal cortex in stressful situations.
With a sudden cancellation, especially in the case of the preceding use of high doses, the development of the "Cancellation" syndrome (anorexia, nausea, inhibition, generalized muscular-skeletal pain, general weakness), as well as the aggravation of the disease, was assigned to the dexamethasone.
During treatment with dexamethasone, vaccination should not be carried out in connection with the decline in its effectiveness (immune response).
Assigning dexamethasone at intercurrent infections, septic conditions and tuberculosis, it is necessary to simultaneously carry out antibiotics of bactericidal action.
In children during long-term treatment, dexamethasone needs careful monitoring of growth and development dynamics. Children, which during the treatment period were in contact with sick cute or chickenpasses, prophylactically prescribe specific immunoglobulins.
Due to the weak mineralocorticoid effect for substitution therapy with adrenal insufficiency, dexamethasone is used in combination with mineralocorticoids.
In patients with diabetes mellitus, the content of blood glucose should be monitored and corrected therapy if necessary.
X-ray control over the bone-articular system (spinal shots, brushes) are shown.
In patients with latent infectious diseases of the kidneys and urinary tract, dexamethasone is able to cause leukocyturia, which may have a diagnostic value.
Dexamethasone increases the content of metabolites of 11- and 17-oxytocorticosteroids.
When pregnancy (especially in the first trimester), the drug can be applied only when the expected therapeutic effect exceeds the potential risk to the fetus. With long-term therapy during pregnancy, the possibility of breach of fetal growth is not excluded. In the case of use at the end of pregnancy, there is a danger of atrophy of the adrenal cortex at the fetus, which may require substitution therapy in a newborn.
If it is necessary to carry out treatment with a drug during breastfeeding, then breastfeeding should be stopped.
In children during the growth period, GCS should be applied only in absolute indications and under particularly thorough observation of the attending physician.
