Ebatin (Ebastine): A Non-Sedating Antihistamine for Allergic Conditions

Ebatin contains Ebastine, a long-acting and selective H1-histamine receptor antagonist. It is classified as a non-sedating antihistamine, primarily used for the symptomatic treatment of various allergic reactions.

How Ebatin Works (Pharmacology)

Ebastine functions as a selective H1-histamine receptor antagonist. This means it blocks the action of histamine at H1 receptors, which are responsible for mediating many allergic symptoms like itching, sneezing, and watery eyes.

• After repeated administration, the inhibition of peripheral H1 receptors remains at a constant level, providing consistent relief.
• Ebastine is rapidly absorbed following oral administration and undergoes extensive first-pass metabolism. It is almost entirely converted to its pharmacologically active acid metabolite, carebastine, which is responsible for its therapeutic effects.

Key Indications & Benefits

Ebatin is indicated for the symptomatic treatment of:

• Seasonal allergic rhinitis (e.g., hay fever).
• Perennial allergic rhinitis (year-round allergies).
• Chronic idiopathic urticaria (chronic hives without a known cause).

Dosage & Administration

Ebastine may be taken with or without food. Always consult a registered physician for medication use.

• 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 (can be increased up to 5 ml in severe cases like Perennial Allergic Rhinitis).
  • Children (6-12 years of age): 5 ml once daily (can be increased up to 10 ml in severe cases like Perennial Allergic Rhinitis).

Important Considerations & Warnings

It is crucial to discuss your full medical history with your doctor before taking Ebatin.

Contraindications:

• Patients with a known hypersensitivity to Ebastine or any of its ingredients.

Side Effects:

• Most common: Headache, dry mouth, and drowsiness.
• Less commonly reported: Abdominal pain, dyspepsia (indigestion), nausea, and insomnia.

Drug Interactions:

• Increased plasma levels of Ebastine and prolonged QTc interval: When combined with ketoconazole (an antifungal) or erythromycin (a macrolide antibiotic).
• No interaction: Ebatin does not interact with the pharmacokinetics of theophylline, warfarin, cimetidine, or diazepam.
• Enhanced sedation: The sedative effect of alcohol and diazepam may be enhanced when taken with Ebatin.

Overdose Effects

• No clinically meaningful signs or symptoms were observed with single doses up to 100 mg.
• No specific antidote for Ebatin exists.
• In case of accidental overdose, gastric lavage, monitoring of vital functions (including ECG), and symptomatic treatment should be carried out.

Storage Conditions

Store below 30°C in a cool and dry place, away from light. Keep out of reach of children.
