Primary Outcome Measures :
  1. 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 :
  1. 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
