详细说明

DrugBank - DB01084

• Drug Groups: approved
• Description: Emedastine is an antihistamine used in eye drops to treat allergic conjunctivitis. [Wikipedia]
• Indication: For the temporary relief of the signs and symptoms of allergic conjunctivitis.
• Pharmacology: Emedastine is a relatively selective H₁-receptor antagonist.
• Toxicity: Somnolence and malaise have been reported following daily oral administration.
• Affected Organisms: Humans and other mammals
• Biotransformation: Two primary metabolites, 5-hydroxyemedastine and 6-hydroxyemedastine, are excreted in the urine as both free and conjugated forms. The 5'-oxoanalogs of 5-hydroxyemedastine and 6-hydroxy-emedastine and the N-oxide are also formed as minor metabolites.
• Absorption: Ophthalmic use of emedastine usually does not produce measurable plasma concentrations.
• Half Life: The elimination half-life of oral emedastine in plasma is 3-4 hours.
• Elimination: Approximately 44% of the oral dose is recovered in the urine over 24 hours with only 3.6% of the dose excreted as parent drug. Two primary metabolites, 5- and 6-hydroxyemedastine, are excreted in the urine as both free and conjugated forms.
