Introduction to Levocetirizine Dihydrochloride
Levocetirizine dihydrochloride is a third-generation antihistamine widely used to alleviate symptoms of allergic rhinitis and chronic idiopathic urticaria. It is known for its efficacy in reducing symptoms such as sneezing, runny nose, and itchy eyes.
Clinical Trials Overview
Short-Term Clinical Trials
Clinical trials involving levocetirizine dihydrochloride have been extensive, covering various age groups and durations. In short-term trials (up to 6 weeks), 1,896 patients aged 12 years and older were treated with levocetirizine dihydrochloride at doses of 2.5 mg, 5 mg, or 10 mg once daily. These trials showed that the most common adverse reactions were somnolence, nasopharyngitis, fatigue, dry mouth, and pharyngitis, with most being mild to moderate in intensity. Somnolence was the most common adverse reaction leading to discontinuation, affecting about 0.5% of patients[1].
Pediatric Clinical Trials
In pediatric patients, levocetirizine dihydrochloride was tested in several trials. For children aged 6 to 12 years, a dose of 5 mg once daily was administered for 4 to 6 weeks. For younger children (1 to 5 years), a dose of 1.25 mg twice daily was given for 2 weeks. Infants aged 6 to 11 months received 1.25 mg once daily for 2 weeks. These trials indicated that the safety profile in children was generally consistent with that in adults, with adverse reactions such as diarrhea and constipation being more common in the treatment group than in the placebo group[1].
Long-Term Clinical Trials
Long-term safety data from two clinical trials involving 428 patients aged 12 years and older treated with levocetirizine dihydrochloride 5 mg once daily for 4 or 6 months showed a similar safety profile to short-term studies. Ten patients (2.3%) discontinued treatment due to somnolence, fatigue, or asthenia. An 18-month trial in 255 subjects aged 12 to 24 months also supported the long-term safety of levocetirizine dihydrochloride[1].
Specific Study Findings
A notable study on seasonal allergic rhinitis (SAR) in US adults found that levocetirizine 5 mg once daily was well tolerated but failed to show significant efficacy compared to placebo. This result was inconsistent with previous studies, highlighting the importance of duplicate studies to avoid false negative results[4].

Pharmacokinetics and Gender Differences
A recent study investigated gender differences in levocetirizine pharmacokinetics. The study found that while there were some differences in pharmacokinetic parameters between males and females, these differences were not significant enough to warrant different dosing recommendations based on gender alone. The antihistamine effects of levocetirizine were consistent across genders, especially when administered at standard intervals[3].
Post-Marketing Experience
In addition to clinical trial data, post-marketing experience has identified various adverse reactions not observed during clinical trials. These reactions are reported voluntarily and include a range of side effects, though their frequency and causal relationship to the drug cannot always be reliably estimated[1].
Key Takeaways
- Clinical Trials: Levocetirizine dihydrochloride has been extensively tested in short-term and long-term clinical trials, showing a generally safe and effective profile.
- Market Growth: The market is expected to grow at a CAGR of 5.5% to 7% driven by increasing allergic conditions and advancements in drug formulation.
