Tofen Tablet 1 mg contains Ketotifen Fumarate, a well-established antiallergic medication used for the prevention and long-term management of allergic conditions. Ketotifen acts as a mast cell stabilizer and antihistamine, making it effective in reducing the frequency and severity of allergic symptoms. It is particularly useful in the prophylactic treatment of bronchial asthma and in the management of various allergic disorders.

Therapeutic Class

Antihistamine and mast cell stabilizer

Indications

Tofen Tablet 1 mg is indicated for:

• Prophylactic treatment of bronchial asthma

• Prevention of asthma attacks (not for acute relief)

• Management of allergic rhinitis (seasonal and perennial)

• Treatment of allergic conjunctivitis

• Relief of symptoms associated with chronic allergic conditions such as urticaria and atopic dermatitis

This medicine is intended for long-term use to control allergic responses and reduce the reliance on other antiallergic therapies.

Pharmacology

Ketotifen is a non-competitive histamine H1-receptor antagonist with mast cell stabilizing properties. It inhibits the release of inflammatory mediators such as histamine, leukotrienes, and platelet-activating factor from mast cells. By preventing mediator release, Ketotifen reduces bronchial hyperreactivity and suppresses allergic inflammation. Unlike bronchodilators, Ketotifen does not provide immediate relief of acute asthma symptoms; instead, it works gradually to prevent allergic reactions over time.

Dosage and Administration

• Adults and children over 3 years: 1 mg twice daily, preferably with food

• Treatment is usually initiated at a lower dose to minimize sedation and then gradually increased

• The tablet should be swallowed whole with water

Clinical improvement may take several weeks; therefore, regular use as prescribed is essential for optimal benefit.
