DEXAMETHASONE - BIOFARM

General characteristics. Structure:

Active ingredients: 1 ml of drug contains phosphate sodium dexamethasone (dexamethasone of phosphate of disodium salt) – 1 mg;

Pharmacological properties:

Pharmacodynamics. Shows the expressed antiinflammatory and antiallergic action caused by release oppression by eosinophils of mediators of an inflammation; induction of formation of lipokortin and reduction of quantity of mast cells which develop a histamine and hyaluronic acid, with reduction of permeability of capillaries; stabilization of cellular membranes (in particular lizosomalny) and membranes of organellas.
 
Pharmacokinetics. At instillations in an eye dexamethasone is soaked up through a cornea with an intact epithelium in moisture of an anterior chamber. At an inflammation of tissues of eye or injury of a mucous membrane and a cornea the speed of absorption of dexamethasone increases.

Indications to use:

Not purulent allergic conjunctivitis, blefarokonjyunktivit, a keratitis, a keratoconjunctivitis without damage of an epithelium, an iritis, an iridocyclitis, an episcleritis, a sclerite, inflammatory processes after injuries of an eye and surgical intervention.
