Pharmacological properties of the drug Methylprednisolone
Synthetic corticosteroids are similar in pharmacological properties to hydrocortisone, but are superior in activity. It has a pronounced anti-inflammatory, antiallergic and immunosuppressive effect. Does not have mineralocorticoid activity. Affects carbohydrate, protein, lipid metabolism. Reduces the number of immunocompetent cells at the site of inflammation, reduces vasodilation, stabilizes lysosomal membranes, and reduces the production of prostaglandins and leukotrienes. Has a catabolic effect. Reduces the absorption of glucose by peripheral tissues, which can lead to hyperglycemia and glucosuria, especially in patients predisposed to diabetes. After oral administration, it is well absorbed in the small intestine. Plasma protein binding is 40–90%. The half-life is 2–4 hours. Metabolized in the liver. It is excreted in the urine, mainly in the form of metabolites (glucuronides, sulfates and unconjugated compounds). The half-life is about 3 hours. The drug penetrates the placental barrier and also into breast milk. After intramuscular administration in the form of a depot suspension at a dose of 40 mg, the maximum concentration in the blood plasma is achieved on average after 7.3 hours and averages 1.48 mcg/100 ml. The half-life is 69.3 hours. The duration of suppression of the hypothalamic-pituitary-adrenal system is 4-8 days. After intra-articular injection of 40 mg depot suspension into each knee joint (total dose 80 mg), the maximum plasma concentration is reached after 4-8 hours and is approximately 21.5 mcg/100 ml. The entry of the active substance into the systemic circulation from the joint cavity persists for approximately 7 days.

Pharmacological properties
Pharmacodynamics
Methylprednisolone is a synthetic glucocorticosteroid. Glucocorticoids penetrate cell membranes and form complexes with specific cytoplasmic receptors that penetrate the cell nucleus, bind to DNA (chromatin), stimulate mRNA transcription and further synthesis of various enzymes, which explains the effect of systemic use of glucocorticoids. Methylprednisolone is an analogue of prednisolone. It is similar in activity to prednisolone, but has virtually no mineralocorticoid activity, which ensures better tolerability. Glucocorticoids not only have a significant effect on the inflammatory process and the immune response, but also affect carbohydrate, protein and fat metabolism, the cardiovascular system, skeletal muscles and the central nervous system.
Effect on inflammation and immune response
Methylprednisolone has anti-inflammatory, desensitizing and angiallergic effects. It has antishock, antitoxic and immunosuppressive properties. Unlike cytostatics, the immunosuppressive properties of methylprednisolone are not associated with a mitostatic effect, but are the result of suppression of various stages of immunogenesis: migration of bone marrow stem cells, migration of B cells and interaction of T and B lymphocytes. Like other corticosteroids, methylprednisolone inhibits the release of cytokines (interleukins 1 and 2, γ-interferon) from lymphocytes and macrophages, inhibits the release of inflammatory mediators by eosinophils, reduces the metabolism of arachidonic acid, thereby achieving the following therapeutic effects: reducing the number of immunoactive cells near the site of inflammation; decreased vasodilation; stabilization of lysosomal membranes; inhibition of phagocytosis; decreased production of prostaglandins and related compounds. A dose of 4 mg of methylprednisolone has the same glucocorticosteroid (anti-inflammatory) effect as 20 mg of hydrocortisone. Methylprednisolone has only minimal mineralocorticoid effects (200 mg methylprednisolone is equivalent to 1 mg deoxycorticosterone). Effect on protein and carbohydrate metabolism Glucocorticoids exhibit a catabolic effect on proteins: they delay the synthesis and accelerate the breakdown of proteins. By stimulating steroid receptors, they induce the formation of a special class of proteins - lipocortins, which have an anti-edematous effect. The amino acids that are released are converted by the process of gluconeogenesis in the liver into glucose and glycogen. The absorption of glucose in peripheral tissues is reduced, which can lead to hyperglycemia and glycosuria, especially in patients prone to diabetes. Effect on fat metabolism Glucocorticoids have lipolytic activity, which manifests itself primarily in the tissues of the extremities, and lipogenetic activity, which is most pronounced in the chest, neck and head, which leads to the redistribution of fat deposits. In relatively high doses, it inhibits the development of lymphoid and connective tissue, including reticuloendothelium; reduces the number of mast cells, which are the site of formation of hyaluronic acid; inhibits the activity of hyaluronidase and helps reduce capillary permeability. The maximum pharmacological activity of corticosteroids occurs when peak plasma concentrations have already passed, so it is believed that the vast majority of therapeutic effects of drugs are due primarily to modification of enzyme activity, and not to direct action of the drug.
Pharmacokinetics
The pharmacokinetics of methylprednisolone is linear, regardless of the route of administration. Absorption The bioavailability of methylprednisolone in healthy people after oral administration is generally high (82-89%). After oral administration, methylprednisolone is rapidly absorbed and the maximum concentration of methylprednisolone in the blood plasma is achieved within 1.5-2.3 hours (depending on the dose) after taking this drug in healthy people. The level of absorption in the distal region is approximately 50% of the level of absorption in the proximal region. Distribution Methylprednisolone is widely distributed in tissues, penetrates the blood-brain barrier and is excreted into breast milk. Forms weak dissociated bonds with albumin and transcortin. Plasma protein binding of methylprednisolone in humans is approximately 77%. The volume of distribution of methylprednisolone is approximately 1/2 kg. Metabolism Methylprednisolone is metabolized in the liver to inactive metabolites. The main metabolites are 20-α-hydroxymethylprednisolone and 20-β-hydroxymethylprednisolone. Its metabolism in the liver occurs primarily with the participation of the CYP3A4 enzyme (for a list of drug interactions based on metabolism mediated by CYP3A isoenzymes, see the section “Interaction with other drugs and other types of interactions”). Conjugation reactions occur mainly in the liver, and to a lesser extent in the kidneys. Excretion Metabolites are excreted mainly in the urine in the form of glucuronides, sulfates and unconjugated compounds. The half-life of total methylprednisolone is 1.8 to 5.2 hours. The total clearance is about 5-6 ml/min/kg. Methylprednisolone is eliminated by hemodialysis.

Directions for use and doses
The initial dose for adults can vary from 4 to 48 mg of methylprednisolone per day, depending on the indication. It is necessary to use the lowest dose of corticosteroids to control the course of the disease. For less severe illnesses, low doses are usually sufficient, although individual patients may require higher starting doses. High doses can be used for diseases and conditions such as multiple sclerosis (200 mg per day), cerebral edema (200-1000 mg per day), organ transplantation (up to 7 mg/kg per day). If satisfactory clinical effect is not achieved after an appropriate period of time, therapy with methylprednisolone tablets should be discontinued and the patient should be given alternative therapy. If after long-term therapy the drug needs to be discontinued, it is recommended that this be done gradually rather than suddenly. If a satisfactory effect is achieved as a result of therapy, an individual maintenance dose should be selected for the patient by gradually reducing the initial dose at certain intervals until the lowest dose is found that will maintain the achieved clinical effect. It should be remembered that constant monitoring of the dosage of the drug is necessary. Situations in which it may be necessary to adjust the dose of the drug include: changes in clinical condition due to the onset of remission or exacerbation of the disease; individual patient response to the drug; exposure to stressful situations on the patient are not directly related to the underlying disease that the therapy is aimed at. In the latter case, it may be necessary to increase the dose of methylprednisolone for a certain period of time, depending on the patient's condition. It should be emphasized that the required dose may vary and should be selected individually depending on the nature of the disease and the patient's response to therapy. Alternating therapy (AT) Alternating therapy is a corticosteroid dosing regimen in which a double dose of glucocorticoids should be prescribed every other day, in the morning. The goal of this type of therapy is to provide the patient who requires long-term therapy with the maximum benefits of corticosteroids while minimizing some of the undesirable effects such as pituitary-adrenal suppression, Cushingoid condition, corticosteroid withdrawal syndrome, and growth suppression in children.

Adverse reactions
The development of severe adverse reactions depends on the dose and duration of treatment. Adverse reactions usually develop with long-term use of the drug; during a short period of use, the risk of their occurrence is unlikely. The following are adverse reactions associated with methylprednisolone therapy, listed according to organ system class, frequency, and severity. In each group, the frequencies of adverse reactions are indicated in order of decreasing severity. The frequency of adverse reactions is shown as: often (from ≥1/100 to
Contraindications
hypersensitivity to methylprednisolone or other components of the drug; systemic infections in cases where specific antimicrobial therapy is not intended; systemic fungal infections; Administration of live or live attenuated vaccines is contraindicated in patients receiving immunosuppressive doses of corticosteroids.
Overdose
No clinical syndrome of acute corticosteroid overdose has been reported. Case reports of acute toxicity and/or death following corticosteroid overdose are rare. In case of overdose, there is no specific antidote; supportive and symptomatic treatment is provided. Methylprednisolone is eliminated by dialysis.
Precautionary measures
Corticosteroids should be used with caution and under strict medical supervision in patients with arterial hypertension, congestive heart failure, diabetes mellitus (or a family history of diabetes), pancreatitis, and diseases of the digestive tract (peptic ulcer, local ileitis, ulcerative colitis or other inflammatory diseases of the digestive tract or diverticulitis with an increased risk of bleeding and perforation), ocular herpes (as corneal perforation is possible), hypothyroidism, history of corticosteroid-induced myopathy, liver failure, cirrhosis, epilepsy, abscess or other pyogenic infections, glaucoma, prone to thrombophlebitis and with mental disorders disorders. Caution must also be exercised when prescribing the drug to patients who have recently suffered a myocardial infarction, with recent intestinal anastomoses and renal failure. Patients with bleeding disorders should be under medical supervision. Immunosuppressive effects/increased susceptibility to infections Corticosteroids may increase susceptibility to infections and mask some symptoms of infections; In addition, new infections may develop during corticosteroid therapy. When using corticosteroids, resistance to infections may decrease and the body may be unable to localize the infection. There is a risk of developing secondary infections caused by bacteria, fungi, viruses, protozoa or helminths from any location in the body, which may occur during the use of corticosteroids as monotherapy or in combination with other immunosuppressive agents that affect the state of cellular and humoral immunity and neutrophil function . These infections can be mild, but can sometimes be severe and even fatal. As the dose of corticosteroids increases, the incidence of infectious complications increases. Patients taking drugs that suppress the immune system are more susceptible to infections than healthy people. Chickenpox and measles, for example, can have more serious or even fatal outcomes in unimmunized children or adults who take corticosteroids. The use of live or live attenuated vaccines is contraindicated in patients receiving immunosuppressive doses of corticosteroids. Patients receiving immunosuppressive doses of corticosteroids can be vaccinated with killed or inactivated vaccines, but their response to such vaccines may be reduced. These immunization procedures can be performed in patients receiving corticosteroids in doses that do not have an immunosuppressive effect. The use of corticosteroids for active tuberculosis should be prescribed only in cases of fulminant or disseminated tuberculosis, when corticosteroids must be used in combination with appropriate anti-tuberculosis therapy. If corticosteroids are indicated for patients with latent tuberculosis or during the period of tuberculin testing, treatment should be carried out under strict medical supervision, since reactivation of the process is possible. During long-term corticosteroid therapy, such patients should be given appropriate prophylactic treatment. Cases of Kaposi's sarcoma have been reported in patients receiving corticosteroid therapy. In such cases, discontinuation of corticosteroid therapy may result in clinical remission. There is no consensus on the role of corticosteroids in the treatment of patients with septic shock. Previous studies have reported both positive and negative effects of corticosteroid use in this clinical setting. Later studies showed that corticosteroids as adjunctive therapy had a beneficial effect in patients with septic shock due to adrenal insufficiency. However, routine use of these drugs in patients with septic shock is not recommended. A systematic review of the data concluded that there was no benefit from short courses of high-dose corticosteroids in these patients. However, a meta-analysis and one review have shown that longer (5-11 days) courses of low-dose corticosteroids may reduce mortality, especially in patients with vasopressor-dependent septic shock. In addition, corticosteroids should be used with great caution in patients with known or suspected parasitic infections, such as strongyloidiasis (acne infestation). In these patients, corticosteroid-induced immunosuppression can lead to strongyloides hyperinfection and dissemination with widespread larval migration, often accompanied by severe enterocolitis and potentially fatal gram-negative septicemia. Effect on the immune system Allergic reactions (eg, angioedema) may occur. Since skin reactions and anaphylactic/anaphylactoid reactions have been reported in rare cases in patients receiving corticosteroid therapy, appropriate precautions should be taken before use, especially if the patient has a history of allergy to any drug. Effects on the endocrine system In patients receiving corticosteroid therapy and who are exposed to stress, increasing the dose of rapid-acting corticosteroids before, during and after a stressful situation is indicated. Long-term use of glucocorticoids can lead to suppression of the hypothalamic-pituitary-adrenal axis (the development of secondary adrenal insufficiency) and contribute to the exacerbation of diseases and the development of complications in various conditions, for example, during acute injuries, diseases or surgery. The degree and duration of adrenocortical insufficiency varies between patients and depends on the dose, frequency, timing of use, and duration of glucocorticoid therapy. This effect can be minimized by using alternating therapy (see section "Dosage and Administration"). High doses of methylprednisolone significantly reduce the risk of developing these complications. If glucocorticoids are suddenly withdrawn, acute adrenal insufficiency may develop, which can be fatal. Adrenocortical insufficiency caused by the use of the drug can be minimized by gradually reducing the dose. This type of relative deficiency can be recorded for several months after discontinuation of therapy, therefore, if stressful situations arise during this period, hormonal therapy must be reinstated. Since mineralocorticoid secretion may be impaired, electrolytes and/or mineralocorticoids should be administered concomitantly. With long-term use of glucocorticoids, therapy should be discontinued gradually over several weeks to avoid “withdrawal syndrome” and serious complications. This syndrome includes symptoms such as anorexia, nausea, vomiting, lethargy, headache, fever, joint pain, desquamation, myalgia, weight loss and/or hypotension. These effects are thought to result from a sudden change in glucocorticoid concentrations rather than from low corticosteroid levels. Long-term therapy should not be stopped suddenly, also in case of pregnancy. Because corticosteroids may cause or worsen Cushing's syndrome, their use should be avoided in patients with Cushing's disease. Particular attention should be paid to the use of corticosteroids in patients with hypothyroidism, which requires frequent monitoring of their condition. Patients with hypothyroidism or severe liver disease should have their dose reduced due to the increased effect of methylprednisolone. Metabolic and nutritional disorders Corticosteroids, including methylprednisolone, may increase blood glucose, worsen the condition of patients with a history of diabetes mellitus, and also contribute to the development of diabetes mellitus in patients using corticosteroids long-term. Mental disorders When using corticosteroids, various mental disorders are possible: from euphoria, insomnia, mood changes, personality changes to severe depression with the expression of psychotic manifestations. In addition, while taking corticosteroids, existing emotional instability and a tendency to psychotic reactions may increase. Particular attention should be paid to the systemic use of corticosteroids in both patients and their first-degree relatives with pre-existing severe affective mental disorders. These disorders include depressive or manic-depressive illness or pre-existing steroid psychosis. Symptoms usually occur within a few days or weeks of starting therapy. Most reactions disappear after reducing the dose or discontinuing the drug, although special treatment may be necessary. Mental reactions have been observed during corticosteroid withdrawal; their frequency is unknown. Patients and their caregivers should be advised to seek medical attention if the patient develops any mental health problems, especially if the patient is suspected of being depressed or having suicidal thoughts. Patients and their caregivers should be alert to possible psychiatric disorders that may occur during or immediately following tapering or discontinuation of systemic steroids. Nervous system disorders Patients with seizures, as well as myasthenia gravis, should use corticosteroids with caution (see information about myopathy in the “Adverse reactions” section). Although controlled clinical trials have demonstrated the effectiveness of corticosteroids in accelerating the reduction of acute symptoms of exacerbations of multiple sclerosis, they have not demonstrated the effect of corticosteroids on the outcome or natural history of this disease. According to the results of these studies, relatively high doses of corticosteroids must be used to demonstrate a significant effect (see section "Dosage and Administration"). Epidural lipomatosis has been reported in patients taking corticosteroids, usually in high doses over a long period of time. Visual disorders In case of eye damage caused by glaucoma (or if close relatives have this disease) or herpes simplex virus, corticosteroids should be used with caution, as this may cause perforation of the cornea. With long-term use of corticosteroids, posterior subcapsular cataracts and nuclear cataracts (especially in children), proptosis, or increased intraocular pressure may develop, which can lead to glaucoma with possible damage to the optic nerve. Patients taking glucocorticoids are at increased risk of developing secondary eye infections caused by fungi and viruses. Corticosteroid therapy has been associated with the development of retinal detachment. Cardiac disorders The negative effects of glucocorticoids on the cardiovascular system, such as dyslipidemia and hypertension, when used long-term in high doses, may contribute to the occurrence of additional cardiovascular adverse events in patients with pre-existing cardiovascular risk factors. In this regard, corticosteroids should be used rationally in such patients, and also take into account the modification of risk factors and, if necessary, additionally monitor cardiac activity. Low doses and alternating therapy may reduce the incidence of complications during corticosteroid therapy. In patients with congestive heart failure, systemic corticosteroids should be used with caution and only when absolutely necessary. Particular caution is required when using systemic corticosteroids in patients with recent myocardial infarction (myocardial rupture has been reported), and frequent monitoring of the patient's condition is necessary. Caution should be exercised in patients receiving cardioactive drugs such as digoxin due to steroid-induced electrolyte imbalance/potassium loss. Vascular disorders Cases of thrombosis, including thromboembolism, have been reported with the use of corticosteroids. Caution should be exercised when prescribing corticosteroids to patients who have or may be susceptible to thromboembolic disorders. Corticosteroids should be used with caution in patients with hypertension. Gastrointestinal disorders High doses of corticosteroids can cause the development of acute pancreatitis. There is no consensus that corticosteroids themselves cause the development of gastric ulcers during therapy. Corticosteroids may make it difficult to diagnose gastrointestinal complications because they reduce pain and may also mask the symptoms of peptic ulcers. In combination with NSAIDs, the risk of developing gastrointestinal ulcers increases. Therefore, aspirin and nonsteroidal anti-inflammatory drugs should be used with caution in combination with corticosteroids. Corticosteroids should be used with caution in ulcerative colitis if there is a risk of gastrointestinal wall perforation, abscess formation, or other purulent infection; with diverticula; in the case of recently performed intestinal anastomoses; with active or latent peptic ulcer. Hepatobiliary disorders Particular attention should be paid to the use of systemic corticosteroids in patients with cirrhosis and liver failure. Isolated hepatobiliary disorders have been reported, most of which were reversible after discontinuation of the drug. Careful monitoring is required. Musculoskeletal disorders Cases of acute myopathy have been reported with the use of high-dose corticosteroids, most often in patients with disorders of neuromuscular transmission (eg, myasthenia gravis) or in patients receiving therapy with anticholinergic drugs that block neuromuscular transmission ( e.g. pancuronium). This acute myopathy is generalized and can affect the eye and respiratory muscles and lead to tetraparesis. An increase in creatine kinase levels may occur. It may take several weeks to several years for clinical improvement or recovery after discontinuation of corticosteroids. Osteoporosis is one of the adverse reactions that is often observed, but rarely diagnosed, and develops with long-term use of high doses of glucocorticoids. During long-term therapy with methylprednisolone, it is necessary to consider prescribing bisphosphonates in patients with osteoporosis or with risk factors for its development. Risk factors for osteoporosis include age over 65 years, a history or family history of frequent fractures, early menopause (before 45 years), premenopausal amenorrhea, and low body weight. The risk of developing osteoporosis can be minimized by adjusting the dose of methylprednisolone to the lowest therapeutic level. Kidney disorders and
Use of the drug Methylprednisolone
Recommended methods of administration: orally, intramuscularly, intra-articularly, periarticularly, intrabursally, into soft tissues, into a pathological focus, instillation into the rectum. The dose is set individually depending on the nature of the disease and its severity. Orally - at an initial dose of 16–96 mg for 24 hours; for long-term treatment, the minimum possible dose should be prescribed; It is advisable to take every other day in the morning. The maintenance dose for adults is 4–12 mg/day. Parenterally: administered intravenously, intravenously and intramuscularly, usually at a dose of 100–500 mg. To eliminate shock conditions and rejection reactions during organ transplantation for a limited time, the dose can be increased to 30 mg/kg. Methylprednisolone in high doses should be administered as an intravenous drip infusion over at least 10 minutes. To eliminate nausea and vomiting caused by taking cytostatics, 250 mg of methylprednisolone is administered 20 minutes before taking cytostatics and 250 mg 6 hours after taking. When treating young and middle-aged children, the dose should be reduced, but it should be at least 25 mg/day. There are the following regimens for the use of methylprednisolone. Continuous circuit. It is administered taking into account the circadian rhythm of endogenous cortisol secretion. For this purpose, 2/3 of the daily dose is prescribed in the morning, 1/3 in the afternoon. Alternating scheme. Prescribe a double dose of methylprednisolone once in the morning every other day. This regimen of use does not reduce the therapeutic effect, but significantly reduces the incidence of side effects, primarily suppression of the hypothalamic-pituitary-adrenal system, compared to continuous use. On break days, it is advisable to prescribe additional NSAIDs. An alternating regimen of use is especially indicated for use in children, since it does not interfere with the normal growth of the child. In case of moderate severity of the pathological process, alternating therapy can be prescribed from the very beginning of the course of treatment. In severe cases, to eliminate acute manifestations of the disease, continuous treatment is required (usually 4–10 days is sufficient for most allergic diseases and collagenoses). Then there are 2 options: 1) switching to alternative therapy with a gradual reduction in the dose of steroids taken every other day; 2) a gradual reduction in the dose of steroids taken on a continuous basis to a maintenance level, after which a transition to an alternating regimen is made. Theoretically, the first option is more promising. Patients taking GCS for a long time on a continuous basis (rheumatoid arthritis) should try to switch to an alternating dose. However, strong suppression of the hypothalamic-pituitary-adrenal axis complicates the task of transferring to an alternating circuit. Perhaps at the first stage there will be a need to take not double, but triple or even quadruple the dose of methylprednisolone every other day. After achieving control over the course of the disease, the dose can be gradually reduced. Intermittent therapy. Similar to alternating, but the use of methylprednisolone is carried out in short courses of 3-4 days, followed by 4-day intervals between courses. Pulse therapy. A fairly rapid infusion of ultra-high doses of methylprednisolone (500–1000 mg) over 30 minutes is used, the course is 3 days. The maximum concentration in the blood plasma after such an infusion is observed during the first hour, after which the drug is quickly redistributed in the body, and after a day its minimum concentration is determined in the serum. Pulse therapy does not cause sudden changes in the biochemical parameters of blood and urine (the concentration of glucose in the blood may increase, which may persist for several days). Changes in the cardiovascular system occur rarely; the most common complication is increased blood pressure; There are reports of the development of arrhythmia (sinus bradycardia), which can persist for 5 days. When conducting pulse therapy, the following rules are adhered to: a strict selection of candidates for pulse therapy is carried out (severe forms of diseases that are not amenable to conventional treatment with corticosteroids, visceral forms of rheumatic diseases); methylprednisolone infusion at a dose of 1000 mg is carried out over 30–40 minutes; monitor the patient’s general condition, heart rate, blood pressure, respiratory rate once before the infusion and at least 3 times during the day after the infusion; immediately respond to any patient complaints that arise during or after the infusion, repeating the clinical examination; They especially monitor the condition of patients with diseases of the cardiovascular system (hypertension, arterial hypertension, heart block) and diabetes mellitus. Advantages of pulse therapy: quick and effective reduction of symptoms; sustainable therapeutic effect (up to 1 year); reduced risk of side effects, positive dynamics during the course of the disease (especially in the early stages of the pathological process). Local application: for rheumatoid arthritis or osteoarthritis, the dose depends on the size of the joint and the severity of the disease; if necessary, injections can be repeated at intervals of 1–5 weeks or more. 20–80 mg of methylprednisolone is injected into a large joint; average - 10–40 mg; small - 4–10 mg. It is important to introduce the solution into the synovial space. For tendonitis and tenosynovitis, it is injected into the tendon sheath; for tendon sheath cysts, it is injected directly into the cyst. The dose is selected individually; it can range from 4 to 30 mg. Injections can be repeated. For skin diseases, 20–60 mg is injected directly into the lesion. For large lesions, it is possible to distribute the dose (20–40 mg) over several local injections. When a high dose is administered, the affected skin may turn white and peel. The course of treatment is 1–4 injections, intervals are individual. Rectal administration of the suspension is indicated for nonspecific ulcerative colitis. Prescribed as microenemas or rectal drips at a dose of 40–120 mg 3 to 7 times a week for 2 weeks or more. In most cases, 40 mg of methylprednisolone in 30–300 ml of water is sufficient. Depot suspension: IM 40–120 mg, if necessary, every 1–4 weeks. Intra-articular, depending on joint size, 4–80 mg as needed every 1–5 weeks. 4–30 mg is injected into the synovial bursae and tendon sheaths, and 20–60 mg into the area of skin lesions (the drug cannot be administered subcutaneously or intradermally). 40–120 mg is administered rectally as an enema 3–7 times a week.

Since complications of therapy with Metipred depend on the dose and duration of treatment, in each specific case, based on an analysis of the risk/benefit ratio, a decision is made on the need for such treatment, and the duration of treatment and frequency of administration are also determined.
In order to better control the patient's condition, the lowest dose of Metypred should be used. When an effect is achieved, if possible, the dose should be gradually reduced to a maintenance dose or treatment should be discontinued.
Due to the danger of developing arrhythmia, the use of the drug Metipred in high doses should be carried out in a hospital environment equipped with the necessary equipment (electrocardiograph, defibrillator).
If prolonged spontaneous remission occurs, treatment should be discontinued.
During long-term treatment, the patient should undergo regular examination (chest x-ray, plasma glucose concentration 2 hours after meals, urinalysis, blood pressure, body weight control, preferably an x-ray or endoscopic examination if there is a history of gastrointestinal ulcers). intestinal tract).
The growth and development of children on long-term therapy with Metipred should be carefully monitored. Growth retardation may occur in children receiving long-term, daily, divided-dose therapy. Daily use of methylprednisolone for a long time in children is possible only for absolute indications. Taking the drug every other day may reduce the risk of developing this side effect or avoid it altogether. Children receiving long-term therapy with Metipred are at increased risk of developing intracranial hypertension.
Metypred should also be prescribed with great caution to patients with confirmed or suspected parasitic infections, such as strongyloidiasis. Immunosuppression caused by methylprednisolone in such patients leads to strongyloid hyperinfection and dissemination of the process with widespread migration of larvae, often with the development of severe forms of enterocolitis and gram-negative septicemia with possible death.
Patients receiving drugs that suppress the immune system are more susceptible to infections than healthy individuals. For example, chickenpox and measles may be more severe and even fatal in unimmunized children or in adults receiving Metypred.
For patients who may be exposed to stress during therapy with Metipred, an increase in the dose of the drug is indicated before, during and after a stressful situation.
During therapy with Metipred, susceptibility to infections may increase, some infections may occur in an erased form, and new infections may develop. In addition, the body’s ability to localize the infectious process is reduced. The development of infections caused by various pathogenic organisms, such as viruses, bacteria, fungi, protozoa or helminths, which are localized in various systems of the human body, may be associated with the use of the drug Metipred, both as monotherapy and in combination with other immunosuppressants that affect on cellular immunity, humoral immunity or neutrophil function. These infections may not be severe, but in some cases they can be severe and even fatal. Moreover, the higher doses of the drug are used, the higher the likelihood of developing infectious complications.
In patients receiving treatment with Metypred in doses that have an immunosuppressive effect, the administration of live or live attenuated vaccines is contraindicated, but killed or inactivated vaccines can be administered, however, the response to the administration of such vaccines may be reduced or even absent. Patients receiving treatment with Metipred in doses that do not have an immunosuppressive effect may be immunized according to appropriate indications. The use of Metypred in active tuberculosis should be limited to cases of fulminant and disseminated tuberculosis, when Metypred is used to treat the disease in combination with appropriate anti-tuberculosis chemotherapy.
If the drug Metypred is prescribed to patients with latent tuberculosis or with positive tuberculin tests, then treatment should be carried out under strict medical supervision, since reactivation of the disease is possible. During long-term drug therapy, such patients should receive appropriate preventive treatment. Kaposi's sarcoma has been reported in patients treated with Metipred. When the drug is discontinued, clinical remission may occur.
When using the drug Metipred in therapeutic doses for a long period, suppression of the hypothalamic-pituitary-adrenal system (secondary adrenal insufficiency) may develop. The degree and duration of adrenal insufficiency is individual for each patient and depends on the dose, frequency of use, time of administration and duration of therapy.
The severity of this effect can be reduced by using the drug every other day or by gradually reducing the dose.
This type of relative adrenal insufficiency may continue for several months after the end of treatment, so in case of any stressful situations during this period, Metypred should be re-prescribed. Since the secretion of mineralocorticosteroids may be impaired, concomitant administration of electrolytes and/or mineralocorticosteroids is necessary. The development of acute adrenal insufficiency, leading to death, is possible with abrupt discontinuation of the drug Metipred. Withdrawal syndrome, which does not appear to be related to adrenal insufficiency, can also occur due to abrupt discontinuation of Metypred. This syndrome includes symptoms such as anorexia, nausea, vomiting, lethargy, headache, fever, joint pain, skin peeling, myalgia, weight loss and low blood pressure. It is assumed that these effects occur due to sharp fluctuations in the concentration of methylprednisolone in the blood plasma, and not due to a decrease in the concentration of methylprednisolone in the blood plasma. In patients with hypothyroidism or cirrhosis of the liver, an increased effect of the drug Metypred is observed. The use of the drug Metypred may lead to an increase in glucose concentrations in blood plasma, worsening the course of existing diabetes mellitus. Patients receiving long-term therapy with Metipred may be predisposed to the development of diabetes mellitus. During therapy with Metipred, various mental disorders may develop: from euphoria, insomnia, mood instability, personality changes and severe depression to acute mental manifestations. In addition, existing emotional instability or tendencies to psychotic reactions may intensify. Potentially severe mental disorders may occur when using the drug Metipred. Symptoms usually appear within a few days to weeks after starting therapy. Most reactions disappear either after reducing the dose or after discontinuation of the drug. Despite this, specific treatment may be required. Patients and/or their relatives should be warned that if changes occur in the patient's psychological status (especially with the development of depression and suicidal attempts), it is necessary to seek medical help. Patients or their relatives should also be warned about the possibility of developing mental disorders during or immediately after reducing the dose of the drug or completely discontinuing it. Long-term use of the drug Metypred can lead to the occurrence of posterior subcapsular cataracts and nuclear cataracts (especially in children), exophthalmos or glaucoma with possible damage to the optic nerve and provoke the addition of a secondary ocular fungal or viral infection. When using the drug Metypred, there is an increase in blood pressure, fluid and salt retention in the body, loss of potassium, and hypokalemic alkalosis. These effects are less pronounced when using synthetic derivatives, except when used in large doses. It may be necessary to limit the intake of salt and foods containing sodium. Therapy with Metypred may mask the symptoms of a peptic ulcer, in which case perforation or bleeding may develop without significant pain. Adverse reactions of the drug Metypred from the cardiovascular system, such as dyslipidemia, increased blood pressure, can provoke new reactions in predisposed patients when using high doses of the drug Metypred and long-term treatment. In this regard, Metypred should be used with caution in patients with risk factors for cardiovascular disease. Regular monitoring of heart function is necessary. The use of low doses of Metypred every other day can reduce the severity of these side effects. Patients taking Metypred should be prescribed acetylsalicylic acid-based analgesics and non-steroidal anti-inflammatory drugs with caution. Allergic reactions are possible. Due to the fact that phenomena such as skin irritation and anaphylactic or pseudoanaphylactic reactions have rarely been observed in patients receiving GCS, the necessary measures should be taken before prescribing GCS, especially if the patient has a history of allergic reactions to drugs. Due to the existing risk of corneal perforation, GCS should be prescribed with caution when treating eye infections caused by the herpes simplex virus (ophthalmoherpes). High doses of GCS can cause acute pancreatitis. Therapy with high doses of GCS can cause acute myopathy; In this case, the disease is most susceptible to patients with disorders of neuromuscular transmission (for example, myasthenia gravis), as well as patients receiving concomitant therapy with anticholinergics, for example, blockers of neuromuscular transmission. This kind of myopathy is generalized; it can affect the muscles of the eyes or respiratory system and even lead to paralysis of all limbs. In addition, creatine kinase levels may increase. In such cases, clinical recovery may take weeks or even years. Osteoporosis is a common (but rarely identified) complication of long-term therapy with high doses of corticosteroids. Corticosteroids are prescribed with caution for long-term therapy in elderly patients due to the increased risk of osteoporosis and fluid retention in body, potentially causing an increase in blood pressure. Concomitant treatment with methylprednisolone and fluoroquinolones increases the risk of tendon rupture, especially in elderly patients. High doses of corticosteroids can cause pancreatitis in children. High doses of methylprednisolone should not be used in cases of brain damage caused by head trauma. Since methylprednisolone can enhance the clinical manifestations of Cushing's syndrome, the use of methylprednisolone should be avoided in patients with Cushing's disease. Careful monitoring of patients receiving systemic corticosteroids and recent history of myocardial infarction. Careful monitoring of patients with a history or current history of thrombosis or thromboembolic complications is necessary.

Contraindicated in premature babies. Overdose Symptoms: edema, hypertension, the appearance of protein in the urine, decreased filtration volume, arrhythmias, hypokalemia, cardiopathy. Treatment: antacids, forced diuresis, potassium chloride, for depression and psychosis - dose reduction or discontinuation of the drug and the prescription of phenothiazines or lithium salts (tricyclic antidepressants are not recommended). Interaction Cyclosporine (inhibits metabolism) and ketoconazole (reduces clearance) increase toxicity. Phenobarbital, diphenhydramine, phenytoin, rifampicin and other inducers of liver enzymes increase the rate of elimination and reduce therapeutic effectiveness. Accelerates the release of aspirin, reduces its level in the blood (when methylprednisolone is discontinued, the level of salicylate in the blood increases and the risk of side effects increases). The action is enhanced by ACTH. Antacids (inhibit absorption), salicylates, butadione, indomethacin increase the likelihood of ulceration of the gastric mucosa, potassium-sparing drugs - severe hyperkalemia, amphotericin B and carbonic anhydrase inhibitors - hypokalemia, heart failure, osteoporosis, cardiac glycosides - arrhythmias, sodium-containing drugs - edema and hypertension. Ergocalciferol and parathyroid hormone prevent osteopathy caused by methylprednisolone. High doses of methylprednisolone reduce the effectiveness of somatotropin. Reduces the activity of oral antidiabetic drugs and the effectiveness of vaccines (live vaccines against the background of methylprednisolone can cause the disease). Mitotane and other inhibitors of adrenal function may necessitate an increase in dose. Special instructions With long-term use, it is necessary to monitor the function of the hypothalamic-pituitary-adrenal system, the level of glucose in the blood serum, and conduct ophthalmological examinations. It is not recommended to inject into the deltoid muscle. Intra-articular applications are carried out no more than once every 3 weeks. Intrathecal administration of a suspension of methylprednisolone acetate is contraindicated. May contribute to the spread or occurrence of infection caused by microorganisms and parasites. It should be used with caution in case of nonspecific ulcerative colitis, diverticula, and myasthenia gravis. Long-term use in children may cause growth retardation. The course must be completed by gradually reducing the dose. Withdrawal may be accompanied by abdominal and joint pain, weakness, nausea, headache, dizziness, fever, loss of appetite, and weight loss. With long-term use, you should reduce the calorie content of food, increase potassium intake, and reduce sodium intake. It is better to calculate the dose in children not per kg of body weight, but per square meter of surface. It is not recommended to mix with other injection solutions. Storage conditions List B. In a dark place at a temperature of 15-25 degrees. WITH.
Special instructions for the use of the drug Methylprednisolone
It should be used with caution and only under the strict supervision of a physician in severe forms of hypertension (arterial hypertension) and chronic heart failure, acute endocarditis, Itsenko-Cushing's disease, psychosis, nephritis, osteoporosis, peptic ulcers, syphilis, active forms of tuberculosis, diabetes mellitus. Caution is also necessary in case of herpetic infections (danger of corneal perforation), ulcerative colitis, diverticulitis, peptic ulcers, myasthenia gravis, and the presence of a recent intestinal anastomosis. In case of acute infectious disease, do not apply topically. Injecting the drug into previously infected joints should be avoided. After intra-articular administration, the joint should be unloaded. This is especially important during the period of symptomatic improvement. If there is exudate and hygroma, a puncture must be performed before administration. Intradermal injection should not be deep. An IM injection is performed deep into the gluteal muscle. It is necessary to avoid injection into the deltoid muscle, since in this case there is a high risk of developing atrophy of the subcutaneous fatty tissue. During treatment with methylprednisolone, vaccinations and immunizations should not be carried out due to the possibility of neurological complications and the lack of antibody formation. During treatment with methylprednisolone, it is possible to suppress reactions in tests with skin allergens. During pregnancy and lactation, it is used only when the expected therapeutic effect for the woman exceeds the potential risk to the fetus or child. Experimental studies revealed the embryotoxic effect of methylprednisolone.
