Deksametazon-MEZ

General characteristics. Structure:

Active ingredient: 1 mg of dexamethasone of sodium (in the form of phosphate).

Excipients: boric acid, pyroborate sodium decahydrate (sodium tetraborate 10-water), a benzetoniya chloride, dinatrium эдетат (disodium salt of ethylene diamine tetraacetic acid), 1 M hydroxide sodium solution to pH 7,4-7,8, the water purified.

Pharmacological properties:

Pharmacodynamics. Dexamethasone - the synthetic fluorinated glucocorticosteroid. Renders antiinflammatory, antiallergic, antiexudative and antipruritic action. Reduces permeability of vessels, slows down migration of leukocytes, phagocytosis, release of kinin, antibody formation. Antiinflammatory effect of drug is 25 times stronger than action of a hydrocortisone.

Pharmacokinetics. After an instillation in an eye well gets into a cornea epithelium, therapeutic concentration in watery moisture of an eye are reached. About 60-70% of the dexamethasone coming to a system blood stream contact proteins of a blood plasma. Dexamethasone at system absorption is metabolized in a liver under the influence of cytochromium enzymes, metabolites are removed through intestines. The elimination half-life averages 3 h.

Duration of local antiinflammatory action after an instillation of 1 drop of solution in a conjunctival sac makes from 4 to 8 h.

Indications to use:

Not purulent and allergic conjunctivitis, keratitis, keratoconjunctivitis without damage of an epithelium of a cornea, an iritis, an iridocyclitis, blefarokonjyunktivit, a blepharitis, an episcleritis, a sclerite, an inflammation after an injury of an eye and operative measures, a sympathetic ophthalmia, recovery of transparency of a cornea and suppression of neovascularization after a keratitis, burns (after full epithelization of a cornea).

From organs of sight: back subkapsulyarny cataract; at a keratitis with a keratohelcosis thinning and perforation of a cornea, development of consecutive infection of eyes, local allergic reactions can be observed; increase in intraocular pressure that can lead to development of glaucoma with damage of an optic nerve, and also decrease in visual acuity and loss of fields of vision.

From cardiovascular system: arrhythmias, bradycardia, increase in arterial pressure.

From a nervous system: nervousness, sleeplessness, dizziness, headache, increase in intracranial pressure.

From the alimentary system: nausea, vomiting, increase or loss of appetite, exacerbation of chronic diseases of digestive tract.
