Mechanism of Action of Nasal Triamcinolone

The antiinflammatory actions of corticosteroids are thought to involve lipocortins, phospholipase A2 inhibitory proteins which, through inhibition of arachidonic acid, control the biosynthesis of prostaglandins and leukotrienes. Firstly, however, these glucocorticoids bind to the glucocorticoid receptors which translocate into the nucleus and bind DNA (GRE) and change genetic expression both positively and negatively. The immune system is suppressed by corticosteroids due to a decrease in the function of the lymphatic system, a reduction in immunoglobulin and complement concentrations, the precipitation of lymphocytopenia, and interference with antigen-antibody binding.
