Histalex Tablet 4 mg contains Chlorpheniramine Maleate, a first-generation antihistamine that provides effective relief from symptoms associated with allergic conditions. This tablet formulation is designed for convenient oral administration, offering rapid and reliable management of allergic rhinitis, urticaria, conjunctivitis, and other histamine-mediated reactions in adults and children.

Allergic reactions occur when the immune system overreacts to allergens such as pollen, dust, pet dander, or certain foods, leading to the release of histamine. Histamine binds to H1 receptors, causing symptoms like sneezing, itching, runny nose, watery eyes, and skin rashes. Histalex Tablet works by blocking H1 receptors, reducing these allergic symptoms efficiently.

Composition

Each tablet contains:

• Chlorpheniramine Maleate 4 mg – an H1 receptor antagonist that inhibits the effects of histamine in allergic responses

The formulation also includes inactive excipients that ensure tablet stability, palatability, and ease of administration.

Mechanism of Action

Chlorpheniramine Maleate functions as an H1 receptor antagonist. Its mechanism includes:

• Blocking histamine receptors: Prevents histamine from binding to H1 receptors in the respiratory tract, skin, and other tissues.

• Reducing allergic symptoms: Alleviates sneezing, nasal congestion, itching, watery eyes, and skin rashes.
