🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by binding to specific glucocorticoid receptors inside cells. Once bound, the receptor-steroid complex moves into the cell nucleus and alters the production of various proteins. It increases the production of anti-inflammatory proteins and decreases the production of pro-inflammatory substances like prostaglandins and leukotrienes. It also suppresses the immune system by reducing the activity of white blood cells and lowering the release of chemicals that trigger allergic and inflammatory responses. This leads to a reduction in swelling, redness, pain, and allergic reactions. At higher doses, it can also affect the balance of salt and water in the body and suppress the natural production of cortisol.
