Insights
Ebastine effectively controlled persistent rhinitis symptoms in children by reducing allergic responses and improving clinical scores. This H1 receptor antagonist demonstrated good tolerance with no observed central nervous system side effects.
Area of Science:
- Allergy and Immunology
- Pharmacology
- Pediatrics
Background:
- Persistent rhinitis significantly impacts children's quality of life.
- Histamine H1 receptor antagonists are key in managing allergic conditions.
- Evaluating Ebastine's efficacy and safety in pediatric persistent rhinitis is crucial.
Purpose of the Study:
- To assess Ebastine's effectiveness in alleviating persistent rhinitis symptoms in children.
- To evaluate the impact of Ebastine on allergic skin test responses and nasal/conjunctival provocation tests.
- To determine the safety profile and tolerance of Ebastine in the pediatric population.
Main Methods:
- A 30-day open-label study involving 30 children with persistent rhinitis.
- Diagnosis confirmed via clinical history, skin prick tests, nasal/conjunctival provocation tests, and IgE levels.
- Clinical scores, skin tests, provocation tests, and adverse events were monitored throughout the study and post-treatment.
Main Results:
- Significant reduction or disappearance of weals in histamine and specific antigen skin tests.
- Decreased response in nasal and conjunctival provocation tests.
- Clinical improvement observed in 24 out of 30 patients; 6 showed no response.
- No central nervous system (CNS) side effects were reported, indicating good drug tolerance.
Conclusions:
- Ebastine effectively improves clinical symptoms of persistent rhinitis in children.
- The drug inhibits skin test reactivity and reduces shock organ sensitivity.
- Ebastine is well-tolerated with a favorable safety profile in pediatric patients.
Abstract:
Ebastine is H1 receptor antagonist, powerful and selective for histamine. Its efficacy has been evaluated in control of symptoms of persistent rhinitis, appearance of secondary effects and tolerance of the drug, in 30 children who were suffering from persistent rhinitis, of which the diagnosis included:- clinical history, skin tests (prick test) nasal and conjunctival provocation tests, total and specific IgE. All the children had treatment for 30 days. The parameters followed were:- clinical score, skin tests, nasal and conjunctival provocations and evaluation of secondary effects, of the start and 10 days after the end of treatment. The results obtained were a disappearance or reduction of the weals from histamine and specific antigens, disappearance or reduction of the response in nasal and conjunctival provocation with carbachol or specific antigens, clear clinical improvement in 22 patients, in 2 small improvement and no response in 6 patients. We conclude that Ebastine improved the clinical symptoms in persistent rhinitis, the skin test is inhibited and sensitivity of the shock organ is reduced. No secondary effects were seen on the Central Nervous System (SNC) and the tolerance of the drug was very good.

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by anesthetizing...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
