Prednisone Pharmacology

Prednisone

About Prednisone
A synthetic Glucocorticoid, Immunosuppressant.
Mechanism of Action of Prednisone
The drug exerts its pharmacological action by penetrating and binding to cytoplasmic receptor protein and causes a structural change in steroid receptor complex. This structural change allows its migration in to the nucleus and then binding to specific sites on the DNA which leads to transcription of specific m-RNA and which ultimately regulates protein synthesis. It exerts more selective glucocorticoid action with little mineralocorticoid actions.
The drug exerts anti-inflammatory and immunosuppressant actions as follows: - 1) Induce lipocortins in macrophages, endothelium, and fibroblasts which inhibits phospholipase A2 and thus decreases the production of Prostaglandins, leukotriens (LT), and platelet activating factor, 2) Causes negative regulation of genes for cytokines in macrophages, endothelial cells and lymphocytes and thus decreases the production of interleukins (IL-1, IL-2, IL-3, IL-6), TNF-a, GM-CSF (granulocyte macrophage colony stimulating factor), Gama interferon and suppresses fibroblast proliferation and T-lymphocyte functions and interferes chemo taxis. 3) Decreases the production of acute phase reactants from macrophages and endothelial cells and interferes complement function. 4) Decreases the production of ELAM-1(Endothelial leukocyte adhesion molecule-1) and ICAM-1(intracellular adhesion molecule-1) in endothelial cells. 5) Inhibit IgE mediated histamine and LT-C4 release from basophiles and the effects of antigen-antibody reaction is not mediated 6) Reduces the production of collagenase and stromolysin and thus prevents tissue destruction
