Oftan Dexamethasone is a local drug for use in ophthalmology with antiallergic, anti-inflammatory effect.
Release form and composition
Dosage form of release - eye drops: transparent, colorless (in polyethylene dropper bottles, 5 ml each, 1 dropper bottle in a cardboard box).
The composition of 1 ml of solution includes:
- Active ingredient: dexamethasone - 1 mg (in the form of dexamethasone sodium phosphate - 1.32 mg);
- Auxiliary components: benzalkonium chloride, boric acid, sodium tetraborate, disodium edetate, water for injection.
Pharmacodynamics and pharmacokinetics
The drug has a pronounced anti-inflammatory and anti-allergic effect.
When interacting with a specific protein receptor in target tissues, the agent regulates the expression of corticoid-dependent genes and affects protein synthesis.
Also, the drug has the following effect on the body:
- stabilization of lysosomal enzymes of leukocyte membranes;
- suppression of the synthesis of antibodies and kinins;
- violation of antigen recognition;
- suppression of mitosis and migration of leukocytes.
All of the described effects are involved in suppressing the local inflammatory response in tissues in response to immune, chemical, or mechanical damage.
The duration of the anti-inflammatory effect after instillation of 1 drop is 4–8 hours.
Systemic absorption when applied topically is low. When instilled into the conjunctival sac, the drug penetrates well into the corneal epithelium and conjunctiva, which leads to the achievement of therapeutic concentrations in the aqueous humor of the eye. In case of damage or inflammation of the mucous membrane, an increase in the rate of penetration is observed.
Approximately 60–70% of dexamethasone entering the systemic circulation binds to plasma proteins. The metabolism of the drug occurs in the liver under the action of CYP3A4 enzymes, the excretion of metabolites is carried out through the intestines. The plasma half-life is about 3.6 ± 0.9 hours.

- Episcleritis, scleritis;
- Conjunctivitis, keratitis, keratoconjunctivitis, non-purulent blepharitis;

- Iridocyclitis, iritis and other uveitis with different etiology;
- Inflammation, edema (including in the period after the operation);
- Inflammation of the posterior segment of the eye (chorioretinitis, choroiditis);
