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.
