Indications
Ebastine is indicated for the symptomatic treatment of:
- Seasonal and Perennial Allergic Rhinitis.
- Chronic Idiopathic Urticaria.
Pharmacology
Ebastine is a long-acting and selective H1-histamine receptor antagonist. After repeated administration, inhibition of peripheral receptors remains at a constant level. Ebastine is rapidly absorbed and undergoes extensive first-pass metabolism following oral administration. Ebastine is almost totally converted to the pharmacologically active acid metabolite, carebastine.
Dosage And Administration
Tablet:
- Adults (more than 12 years of age): 10 mg (one tablet) once daily.
- Children (6-12 years of age): 5 mg (half tablet) once daily.
Syrup:
- Children (2-5 years of age): 2.5 ml once daily (upto 5 ml in severe cases such as Perennial Allergic Rhinitis).
- Children (6-12 years of age): 5 ml once daily (upto 10 ml in severe cases such as Perennial Allergic Rhinitis).
Ebastine may be taken with or without food.
Interaction
Ebastine in combination with either ketoconazole or erythromycin increases in plasma level of ebastine and prolonged QTc interval. Ebastine does not interact with the pharmacokinetics of theophylline, warfarin, cimetidine, diazepam or alcohol. The sedation effect of alcohol and diazepam may be enhanced.
Contraindications
Patients with a known hypersensitivity to Ebastine or any of its ingredients.
