Glucocorticosteroid

Pharmacological Action

Glucocorticosteroid. It has anti-inflammatory, anti-allergic, desensitizing, anti-shock, antitoxic and immunosuppressive effects, and also has a pronounced and diverse effect on various types of metabolism.

It suppresses the release of ACTH and beta-lipotropin by the pituitary gland but does not reduce the level of circulating beta-endorphin. It inhibits the secretion of TSH and FSH.

It increases the excitability of the central nervous system, reduces the number of lymphocytes and eosinophils, and increases the number of red blood cells (stimulates the production of erythropoietins).

It interacts with specific cytoplasmic receptors and forms a complex that penetrates the cell nucleus and stimulates the synthesis of mRNA; the latter induces the formation of proteins, including lipocortin, which mediate cellular effects. Lipocortin inhibits phospholipase A₂, suppresses the release of arachidonic acid and inhibits the synthesis of endoperoxides, prostaglandins, leukotrienes, which contribute to the processes of inflammation and allergy.

The anti-inflammatory effect is associated with the inhibition of the release of inflammatory mediators by eosinophils; induction of lipocortin formation and reduction of the number of mast cells producing hyaluronic acid; with a decrease in capillary permeability; stabilization of cell membranes and organelle membranes (especially lysosomal).

The anti-allergic effect develops as a result of suppression of the synthesis and secretion of allergy mediators, inhibition of the release of histamine and other biologically active substances from sensitized mast cells and basophils, T- and B-lymphocytes, mast cells, decreased sensitivity of effector cells to allergy mediators, inhibition of antibody formation, and changes in the body’s immune response.

The anti-shock and antitoxic effect is associated with an increase in blood pressure (due to an increase in the concentration of circulating catecholamines and restoration of sensitivity to them of adrenergic receptors, as well as vasoconstriction), a decrease in vascular wall permeability, membrane-stabilizing properties, and activation of liver enzymes involved in the metabolism of endo- and xenobiotics.

In COPD, the action is based mainly on the inhibition of inflammatory processes, suppression of the development or prevention of edema of the mucous membranes, inhibition of eosinophilic infiltration of the submucosal layer of the bronchial epithelium, deposition of circulating immune complexes in the bronchial mucosa, as well as on the inhibition of erosion and desquamation of the mucous membrane. It increases the sensitivity of beta-adrenergic receptors of small and medium caliber bronchi to endogenous catecholamines and exogenous sympathomimetics, and reduces the viscosity of mucus by inhibiting or reducing its production.

The immunosuppressive effect is due to the inhibition of the release of cytokines (interleukin-1, interleukin-2, interferon gamma) from lymphocytes and macrophages.

It suppresses the synthesis and secretion of ACTH and secondarily – the synthesis of endogenous glucocorticosteroids. It inhibits connective tissue reactions during the inflammatory process and reduces the possibility of scar tissue formation.

Protein metabolism: reduces the amount of protein in plasma (due to globulins) with an increase in the albumin/globulin ratio, increases the synthesis of albumin in the liver and kidneys; enhances protein catabolism in muscle tissue.

Lipid metabolism: increases the synthesis of higher fatty acids and triglycerides, redistributes fat (accumulation of fat mainly in the shoulder girdle, face, abdomen), leads to the development of hypercholesterolemia.

Carbohydrate metabolism: increases the absorption of carbohydrates from the gastrointestinal tract; increases the activity of glucose-6-phosphatase, leading to an increase in the release of glucose from the liver into the blood; increases the activity of phosphoenolpyruvate carboxykinase and the synthesis of aminotransferases, leading to the activation of gluconeogenesis.

Water-electrolyte metabolism: retains sodium and water in the body, stimulates the excretion of potassium, reduces the absorption of calcium from the gastrointestinal tract, “leaches” calcium from the bones, and increases renal excretion.

Betamethasone sodium phosphate is a readily soluble compound that is well absorbed after parenteral administration into tissues and provides a rapid effect.

Betamethasone dipropionate has slower absorption. By combining these salts, it is possible to create drugs with both short-term (but rapid) and long-term action. Depending on the method of application (intravenous, intramuscular, intra-articular, periarticular, intradermal), a general or local effect is achieved.

Pharmacokinetics

Betamethasone sodium phosphate is highly soluble in water and after intramuscular injection is rapidly hydrolyzed and absorbed almost immediately from the injection site, which ensures a rapid onset of therapeutic action. It is almost completely eliminated within one day after administration.

Betamethasone dipropionate is slowly absorbed from the depot, metabolized gradually, which determines its prolonged action, and is eliminated over more than 10 days.

The binding of betamethasone to plasma proteins is 62.5%. It is metabolized in the liver with the formation of predominantly inactive metabolites. It is excreted mainly by the kidneys.

Dosage Regimen

Determine the dosage individually based on disease severity and patient response.

Administer the suspension by deep intramuscular injection into the gluteal muscle.

For most conditions in adults, the usual initial dose is 1-2 ml (7-14 mg total betamethasone).

Repeat administration as needed, guided by clinical response and disease recurrence.

For intra-articular, intrabursal, or tendon sheath administration, use smaller volumes.

The dose for intra-articular injection depends on joint size; for large joints, use 1 ml (7 mg).

Do not administer more than 1 ml per intradermal injection site.

Avoid subcutaneous administration to prevent tissue atrophy.

Do not administer intravenously, epidurally, or intrathecally.

Use the lowest effective dose for the shortest necessary duration.

Taper the dose gradually when discontinuing after long-term therapy.

Monitor patients for signs of adrenal insufficiency during and after treatment.

For intra-articular administration: general severe condition of the patient, ineffectiveness (or short duration) of the action of 2 previous injections (taking into account the individual properties of the corticosteroids used).

Use in Pregnancy and Lactation

Use during pregnancy is not recommended.

Betamethasone crosses the placental barrier. Animal studies have recorded fetal malformations and developmental disorders (delay) with the use of corticosteroids during pregnancy.

With long-term or repeated use of corticosteroids during pregnancy, the risk of intrauterine growth retardation may increase. Cases of myocardial hypertrophy and gastroesophageal reflux have been reported in newborns when betamethasone was used during pregnancy.

Newborns whose mothers received therapeutic doses of corticosteroids during pregnancy should be under medical supervision (for early detection of signs of adrenal insufficiency).

Contraindicated for use during lactation (breastfeeding).

Special Precautions

This medicinal product should be used at the lowest effective dose for the minimum duration. The initial dose is adjusted until the desired therapeutic effect is achieved. Then the dose is gradually reduced to the minimum effective maintenance dose. If there is no effect from the therapy or after its long-term use, withdrawal is carried out gradually by reducing the dose. Patient monitoring should be carried out for at least one year after the end of long-term therapy or use in high doses.

If a stressful situation arises or is threatened (not related to the disease), it may be necessary to increase the dose.

Administration of the drug into soft tissues, into the lesion, and intra-articularly, while having a pronounced local effect, can simultaneously lead to a systemic effect.

When used in patients with diabetes mellitus, adjustment of hypoglycemic therapy may be required.

Patients receiving corticosteroids should not be vaccinated against smallpox. Other immunization should not be carried out in patients receiving corticosteroids (especially in high doses!), due to the possibility of developing neurological complications and a low immune response (“lack of antibody formation”). However, immunization is possible when carrying out replacement therapy (for example, for primary adrenal cortex insufficiency).

Patients receiving this combination in immunosuppressive doses should be warned to avoid contact with patients with chickenpox and measles (especially important when using the drug in children).

Suppression of the reaction during skin tests while using corticosteroids is possible. It should be taken into account that corticosteroids can mask the signs of an infectious disease and also reduce the body’s resistance to infections.

Suppression of the reaction during skin tests while using corticosteroids is possible.

The effect of corticosteroids is enhanced in patients with hypothyroidism and liver cirrhosis.

Caution should be exercised when using corticosteroids in elderly patients; in patients with renal or hepatic insufficiency, diverticulitis, active or latent gastric and/or intestinal ulcer disease or with recently created intestinal anastomoses, osteoporosis, myasthenia, confirmed or suspected parasitic infections (for example, strongyloidiasis).

The development of secondary adrenal cortex insufficiency due to too rapid withdrawal of corticosteroids is possible for several months after the end of therapy.

While using corticosteroids, changes in sperm motility and count are possible. During long-term corticosteroid therapy, it is advisable to consider switching from parenteral to oral administration of corticosteroids, taking into account the benefit/risk assessment.

Use in Pediatrics

Children undergoing therapy (especially long-term) with a drug containing this combination should be under careful medical supervision for possible growth retardation and development of secondary adrenal cortex insufficiency.

Use in Athletes

Patients participating in competitions under the control of the World Anti-Doping Agency (WADA) should familiarize themselves with the WADA rules before starting treatment with a drug containing this combination, as the use of such drugs may affect the results of doping control.

Drug Interactions

With simultaneous use of phenobarbital, rifampicin, phenytoin, or ephedrine, acceleration of betamethasone metabolism with a decrease in its therapeutic activity is possible.

With simultaneous use of corticosteroids and estrogens, dose adjustment of betamethasone may be required (due to the risk of overdose).

With concurrent use of betamethasone and potassium-excreting diuretics, the likelihood of hypokalemia increases.

Concomitant use of corticosteroids and cardiac glycosides increases the risk of arrhythmia or digitalis intoxication (due to hypokalemia). Betamethasone may enhance potassium excretion caused by amphotericin B.

With concurrent use of betamethasone and indirect anticoagulants, changes in blood clotting are possible, requiring adjustment of the anticoagulant dose.

With combined use of corticosteroids with NSAIDs or with ethanol and ethanol-containing drugs, an increase in the frequency or intensity of erosive and ulcerative lesions of the gastrointestinal tract is possible.

With concurrent use, corticosteroids may reduce the plasma concentration of salicylates.

Simultaneous administration of corticosteroids and somatotropin may lead to slower absorption of the latter (administration of betamethasone doses exceeding 300-450 mcg/m²/day should be avoided).

Corticosteroids may affect the nitroblue tetrazolium test for bacterial infection and cause a false-negative result.

Aminoglutethimide may reduce corticosteroid-induced suppression of adrenal function.

With simultaneous use of corticosteroids and ketoconazole or itraconazole, an increase in the systemic side effects of corticosteroids is possible.

Corticosteroids can reduce the effect of cholinesterase inhibitors, which can lead to the development of severe muscle weakness in patients with myasthenia. If possible, cholinesterase inhibitors should be discontinued at least 24 hours before starting corticosteroid therapy.

With simultaneous use of corticosteroids and isoniazid, a decrease in the plasma concentration of isoniazid is possible. The condition of patients taking isoniazid should be carefully monitored.

Concomitant use of cyclosporine and corticosteroids may lead to an increase in cyclosporine concentration and enhancement of the corticosteroid effect. There is a high risk of seizures.

With simultaneous use of corticosteroids with macrolide antibiotics, a significant decrease in corticosteroid excretion is possible.

With simultaneous use with cholestyramine, an increase in corticosteroid excretion is possible.
