– water for injection.In appearance, the drug is an aqueous suspension of white color. With prolonged storage, it may delaminate, which disappears with shaking.Pharmacological properties for cortexona:
Pharmacotherapeutic group: hormonal drug. Dexamethasone, which is part of the drug, is a glucocorticosteroid, methylated derivative of fluoroprednisolone. It has a pronounced and prolonged anti-inflammatory, anti-allergic, desensitizing effect, and has immunosuppressive activity.
The mechanism of action of the hormone is to block the release of inflammatory mediators by eosinophils, including prostaglandins, which potentiate the inflammatory process;
in stimulating the biosynthesis of lipocartins with decongestant activity;
in reducing the permeability of capillaries and the number of mast cells that produce hyaluronic acid.The immunosuppressive effect is due to inhibition of the release of cytokines (interleukin – 1,2, gamma interferon) from lymphocytes and macrophages, inhibition of proliferation of lymphoid tissue and cellular immunity, and a violation of the kinetics of T-lymphocytes.
The main effect of dexamethasone on metabolism is associated with protein catabolism, increased gluconeogenesis in the liver, and decreased glucose utilization by peripheral tissues.
After intramuscular administration, the maximum plasma concentration of dexamethasone is detected after 60 minutes.cortexona
The therapeutic concentration in the blood serum lasts 30-96 hours, depending on the type of animal. The bioavailability of dexamethasone with intramuscular injection of the drug is 100%. Biotransformation of dexamethasone occurs in the liver and partially in the fibroblasts involved in the metabolism. As a result, 17-hydroxycorticoids are formed that do not have biological activity, and 17-ketosteroids with androgenic effect are formed as well. Metabolites bind to glucuronic acid and sulfates in the liver and kidney x, where they turn into water-soluble sulfuric esters and ricoronids, which are rapidly excreted in urine (75%) and bile (25%).
