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.
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.
Patients with a known hypersensitivity to Ebastine or any of its ingredients.
The most common side-effects are headache, dry mouth and drowsiness. Less commonly reported side effects include abdominal pain, dyspepsia, nausea and insomnia.
No clinically meaningful signs or symptoms were observed up to 100 mg given once daily. There is no specific antidote for Ebastine. In case of accidental overdoses, gastric lavage, monitoring of vital functions including ECG and symptomatic treatment should be carried out.
