Further study details as provided by UCB Pharma:

Primary Outcome Measures:
  • Compare the activity of levocetirizine and desloratadine on allergen-induced wheal and flare reaction. Response to allergen administered by skin prick test (SPT) measured by the wheal and flare surface areas [ Time Frame: 15 minutes ]

Secondary Outcome Measures:
  • Compare the AUC from pre-dose to 24 hours post-dose between levocetirizine and placebo and between desloratadine and placebo obtained for wheal and for flare areas. Compare the AUC from pre-dose to 12 hours post-dose
