Material and Methods: Thirty seven young men age 27 12 year, patients suffering from persistent rhinitis were randomized into three groups which received 10 mg/day of cetirizine, 5 mg/day of levocetirizine or placebo respectively. The skin microcirculation reaction after 10 mg/ml histamine administration was estimated visually on the forearm (diameter of wheal and flare) and by laser Doppler flowmetry before and after study drug or placebo administration 24 hours and every 30 days during the time of the study.
Additional administration of epinephrine, often in the form of an autoinjector (Epi-pen), is required by people with such hypersensitivities.
H-antihistamines can be administered topically (through the skin, nose, or eyes) or systemically, based on the nature of the allergic condition.
