Bromfeniramina maleato, also widely known by its English name brompheniramine maleate, is an antihistamine medication primarily used for the symptomatic relief of various allergic conditions. It functions as a histamine H1 receptor antagonist, meaning it blocks the action of histamine, a natural substance in the body that causes allergic symptoms.
Understanding Bromfeniramina Maleato
This compound is the maleic acid salt of brompheniramine. This chemical structure allows it to effectively interact with histamine receptors in the body. Its primary role is that of an anti-allergic agent, providing relief from discomfort associated with allergic reactions.

How Does It Work?
As a histamine H1 receptor antagonist, bromfeniramina maleato works by blocking the effects of histamine. When the body encounters an allergen (like pollen, dust mites, or pet dander), it releases histamine, which then binds to H1 receptors and triggers a cascade of allergic responses. By preventing histamine from binding to these receptors, bromfeniramina maleato helps to reduce symptoms such as:
- Itching
- Sneezing
- Runny nose
- Watery eyes
Therapeutic Uses
Bromfeniramina maleato is commonly prescribed for the symptomatic relief of a range of allergic conditions. Its effectiveness makes it a valuable option for managing seasonal and perennial allergies.
Key conditions for which it is used include:
- Rhinitis (Hay Fever): This involves inflammation of the nasal passages, leading to symptoms like sneezing, nasal itching, congestion, and a runny nose. Bromfeniramina maleato helps alleviate these irritating symptoms.
- Conjunctivitis (Allergic Eye Inflammation): Characterized by red, itchy, watery eyes, and sometimes swollen eyelids, allergic conjunctivitis can be significantly eased by this antihistamine.
It's important to note that while it provides significant relief from symptoms, it does not cure the underlying allergy.
