Dược Lực Học : Medrysone is a topical anti-inflammatory corticoidsteroids for ophthalmic use. In patients with increased intraocular pressure and in those susceptible to a rise in intraocular pressure, there is less effect on pressure with medrysone than with dexamethasone or betamethasone. Corticoidsteroids inhibit the edema, fibrin deposition, capillary dilation, and phagocytic migration of the acute inflammatory response, as well as capillary proliferation, deposition of collagen, and scar formation.
Cơ Chế Tác Dụng : Medrysone is a corticosteroid used in ophthalmology. [Wikipedia] There is no generally accepted explanation for the mechanism of action of ocular corticosteroids. However, corticosteroids are thought to act by the induction of phospholipase A2 inhibitory proteins, collectively called lipocortins. It is postulated that these proteins control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes by inhibiting the release of their common precursor, arachidonic acid. Arachidonic acid is released from membrane phospholipids by phospholipase A2. Initially, the drug binds to the glucocorticoid receptor in the cytosol. This migrates to the nucleus and binds to genetic elements which cause activation and repression of the involved genes in the inflammatory pathway.
