Pharmacology & Mechanism of Action
Dexamethasone is a cortisone derivative whose high activity due to the presence of methyl group in the 16-alpha position and of a fluorine atom in the 9-alpha position. The result is that its anti-inflammatory activity is 30 times greater and its overall therapeutic effectiveness 8-10 times greater than that of hydrocortisone. Like other glucocorticoids, it is anti-allergic, anti-exudative and anti-proliferative. Therapeutic concentrations of Dexamethasone are found in both the cornea and aqueous humor 15-30 minutes after local application of single drop of 0.1% solution. These concentrations persist for 4-6 hours. The action of Dexamethasone is to inhibit the phospholipase A2, the first step in prostaglandin synthesis. Also, Dexamethasone inhibits the chemotactic infiltration of neutrophils into the site of inflammation.
