Pharmacokinetic Study of Levocetirizine Oral Solution
|ClinicalTrials.gov Identifier: NCT01622283|
Recruitment Status : Completed
First Posted : June 19, 2012
Last Update Posted : June 12, 2017
This study will be a single center, open-label, randomized, single dose, in the fasted condition and 2-way crossover study to evaluate the pharmacokinetics, the safety and tolerability of levocetirizine oral solution 5 mg and cetirizine dry syrup 10 mg in Japanese healthy male subjects.
Approximately 20 subjects will receive both treatments of levocetirizine oral solution 5 mg and cetirizine dry syrup 10 mg in the design. Serial pharmacokinetic samples will be collected and safety assessments will be performed following each dose.
The primary objective of the study is to demonstrate the bioequivalence of levocetirizine in plasma, when given as levocetirizine oral solution 5 mg relative to cetirizine DS 10 mg in Japanese healthy male subjects.
