Dexamethasone(injection solution 0.4 %)


Dexamethasonesolutio pro injeсtionibus

International nonproprietary name (INN)


Pharmacotherapeutic group

Glucocorticoids for systemic dosing.


Active ingredient – dexamethasone sodium phosphate (calculated on dexamethasone phosphate) – 4.0 g;

Auxiliary substances: glycerol, sodium phosphate bisubstituted dihydrous or sodium phosphate bisubstituted 12-hydrous, disodium ethylene diamine salt -N, N, N', N'- tetraacetic acid dihydrous, injection water.



Interaction with specific cytoplasmatic receptors and formation of complex penetrating cell nucleus and stimulating synthesis of mRNA; the latter induces protein formation meditating cellular activity, inclusive lipocortin that inhibits phospholipase A2, inhibits liberation of arachidonic acid and biosynthesis of endoperoxides, PG, leukotriene, provoking inflammatory process, allergy and others. It hampers liberation of mediators of inflammation from eosinophils and labrocytes It inhibits the activity of hyaluronidase, collagenase and protease, normalizes intracellular matrix of cartilaginous tissue and bone tissue functions. It reduces vascular permeability, stabilizes cell membranes, inclusive lysosomal ones, inhibits liberation of cytokines (interleukine and gamma-interferon) from lymphocytes and macrophages, induces involution of lymphoid tissue. It compensates sensitivity of adrenoreceptors to catecholamine. It accelerates protein catabolism, reduces glucose consumption by peripheral tissues and stimulates hepatic gluconeogenesis. It reduces absorption and increases calcium excretion retaining sodium (and water) secretion of ACTH.


i.v. injection: the drug is bound with specific protein-carrier transcoritin by 70-80%; in higher doses drug binding with protein is reduced to 60-70% due to transcoritin saturation. It easily penetrates histohematogenous barriers, either blood-brain and placental one. It is readily absorbed mainly in proximal section of small intestine, absorption in distal section is about half of that of proximal. Смахis reached in 1-2 h. Liver biotransformation mainly by conjugation with glucuronic and sulfuric acids to inactive metabolites. Blood half-decomposition Т1/2 is 3-5 h., biological period of half-excretion is 36-54 h. In parenteral dosing it metabolizes more rapidly, and pharmacological action is less-term. It is mainly urine-excreted (less by lactation glands) as 17-ketosteroids, glucuroids, sulphates. Urine-excretedabout 15% oforiginaldexamethasone. After skin application the absorption depends on many factors (integrity of skin surface, occlusive dressing, dosage form, etc.) and is highly variable.
