| Main Objective: The purpose of the present study is to examine how effective is prophylactically given rupatadine 10 mg against immediate and delayed symptoms caused by experimental mosquito bites in adult subjects allergic to the mosquito bites (ICD classification codes for patients: T14.0 bite of non-venomous insect and L50.0 urticaria). ;Secondary Objective: possible placebo effect ;Primary end point(s): Bite lesion size in mm2 (mean of the two bite lesions; calculated from two perpendicular diameters of the each bite lesion) and accompanying pruritus (VAS) measured under rupatadine and under placebo are compared in each subject with Wilcoxon's signed rank test with Hommel's adjusted P-value. Calculations will be performed separately for measurements at 15 min and at 24 h. | — |
