Uses

For the temporary relief of the signs and symptoms of allergic conjunctivitis.

Emedastine is also used to associated treatment for these conditions: Seasonal Allergic Conjunctivitis

How Emedastine works

Emedastine is a relatively selective, histamine H₁ antagonist. In vitro examinations of emedastine's affinity for histamine receptors demonstrate relative selectivity for the H₁ histamine receptor. In vivo studies have shown concentration-dependent inhibition of histamine-stimulated vascular permeability in the conjunctiva following topical ocular administration. Emedastine appears exert negligible effects on adrenergic, dopaminergic and serotonin receptors.

Toxicity

Somnolence and malaise have been reported following daily oral administration.

Food Interaction

No interactions found.

Elimination Route

Ophthalmic use of emedastine usually does not produce measurable plasma concentrations.

Half Life

The elimination half-life in the plasma is 3-4 hours following oral administration.

Elimination Route

Following oral administration, approximately 44% of the total dose can be recovered in the urine over the 24-hour period, with only 3.6% of the dose excreted as unchanged form. Two primary metabolites, 5- and 6-hydroxyemedastine, are excreted in the urine as both free and conjugated forms.
