The drug has the ability to activate specific receptors, which are located in the cytoplasmic membrane of target organ cells. The substance promotes the synthesis of matrix RNA and the formation of lipocortin proteins. One of these proteins – lipomodulin inhibits the enzyme phospholipase A2.
The tool has an impact on all kinds of metabolic processes, has antianabolic and catabolic effects. Triamcinolone also reduces the need for glucose in tissues that depend on insulin, stimulates the production of glycogen in the liver and lipid degradation processes.
Under the action of drugs based on this compound there is a delay of sodium ions, water and active excretion of potassium ions, parathyroid hormone begins to stand out more intensively, which is responsible for the mobilization of calcium from bone tissue. Due to the ability of the substance to stabilize the membranes of mast cells and lysosomes, to stop the proliferation of connective tissue, to stop the liberalization of arachidonic K-you and reduce the level of its metabolism, Triamcinolone drugs have a pronounced anti-inflammatory activity.

Also, the substance has antitoxic and anti-shock effect on the body, increases blood pressure, increases the concentration of catecholamines, restores the adrenoceptors, reduces the permeability of blood vessels, activates liver enzymes.
After oral administration means 25% absorbed through the walls of the gastrointestinal tract. The maximum effect is visible after 60-120 minutes. With intramuscular administration, this indicator is observed after 1-2 days. About 68% of the active component binds to plasma proteins. For tablets the elimination half-life = 5 hours. The effect of taking the tablets is maintained for 2.5 days, after intramuscular injection – up to 6 weeks, with the introduction of the joint cavity — a few weeks. The compound is metabolized in the liver, formed metabolites are inactive. The drug is excreted through the kidneys and intestines.
