Levocetirizine for Allergic Asthma
(HAS3 Trial)
Trial Summary
What is the purpose of this trial?
This is a randomized, double-blind, placebo-controlled, crossover study comparing asthma control post treatment in African American/Black and Caucasian/White children in both hyper and hypo responsive HILD (Histamine Lontophoresis with Laser Doppler monitoring) phenotypes with uncontrolled persistent allergic asthma using Levocetirizine (LTZ) vs placebo.
Will I have to stop taking my current medications?
The trial requires participants to stop taking medications that affect histamine response. If you are currently on or have been on Tricyclic Antidepressants in the past 30 days, you cannot participate.
What evidence supports the effectiveness of the drug Levocetirizine for allergic asthma?
Is Levocetirizine safe for humans?
Levocetirizine is generally well tolerated and considered safe for humans, with studies showing it has a low potential for drug interactions and does not affect cognition, psychomotor function, or the cardiovascular system. It is widely used for treating allergies and has a wide therapeutic index, meaning it is unlikely to cause severe side effects.12367
How does the drug Levocetirizine differ from other treatments for allergic asthma?
Levocetirizine is a newer generation antihistamine that works by blocking H1 receptors to reduce allergy symptoms without causing drowsiness. It is known for its rapid onset, long-lasting effects, and low potential for drug interactions, making it a unique option compared to other antihistamines.12378
