Asthafen Tablet (Ketotifen)
Asthafen Tablet is used to prevent chronic asthma and treat allergic conditions like rhinitis. It is used to treat allergy symptoms such as stuffy nose, sneezing, runny nose, itching, or watery eyes.
Product Overview
Asthafen Tablet is a prophylactic medication used in the long-term management of allergic conditions such as allergic rhinitis, hay fever, and asthma. Containing Ketotifen, it belongs to the class of medications known as mast cell stabilizers and antihistamines. Unlike "rescue" inhalers that treat acute attacks, Asthafen is a preventive therapy designed to reduce the frequency and severity of allergic reactions over time. By stabilizing the body's immune response, it helps individuals maintain better respiratory health and manage chronic allergic symptoms.
Product Composition
The therapeutic action of this tablet is derived from its specialized active ingredient:
- Ketotifen (as Fumarate): A potent benzocycloheptathiophene derivative that exhibits strong antihistaminic properties and prevents the release of inflammatory mediators.
Product Specification
| Feature | Details |
| Therapeutic Class | Mast Cell Stabilizer / Antihistamine |
| Active Ingredient | Ketotifen |
| Dosage Form | Oral Tablet |
| Primary Indication | Prophylaxis of Bronchial Asthma and Allergic Conditions |
| Common Strength | 1 mg |
Mechanism of Action
Asthafen works through a dual-action process to inhibit the allergic cascade before it escalates:
- Mast Cell Stabilization: It prevents mast cells from rupturing and releasing inflammatory chemicals like histamine and leukotrienes, which are responsible for airway constriction and swelling.
- H1-Receptor Antagonism: It blocks histamine from binding to its receptors, effectively neutralizing allergic symptoms such as itching, sneezing, and watery eyes.
- Eosinophil Inhibition: It inhibits the accumulation and activation of eosinophils (white blood cells involved in allergic inflammation) in the airways, reducing hyper-responsiveness.
- PAF Antagonism: It interferes with Platelet Activating Factor (PAF), a key mediator that contributes to bronchial hyper-reactivity and airway inflammation.
Key Benefits
- Reduction in Asthma Attacks: When taken consistently, it significantly decreases the frequency and intensity of asthma episodes.
- Comprehensive Allergy Control: Provides systemic relief for multiple allergic manifestations, including hay fever and skin reactions.
- Steroid-Sparing Effect: For some patients, long-term use of Asthafen may allow for a reduction in the dosage of corticosteroids or other anti-asthmatic drugs.
- Effective for Pediatric Use: Frequently used in children who suffer from multi-systemic allergic issues, such as atopic dermatitis and asthma.
- Convenient Oral Dosing: Offers a non-invasive alternative or supplement to inhaler-based therapies for long-term stabilization.
Precautions
Asthafen Tablet (Ketotifen) should be used carefully to ensure safe and effective control of allergy and asthma symptoms.
