Cetirizine peripheral antihistaminic activity was assessed by determining the onset and extent of suppression of histamine-induced wheals produced by intradermal injections of 0.05 mL of histamine phosphate, 1.0 mg/mL (Glaxo Smithkline Canada Limited Co, Toronto, ON, Canada).
By comparing these plasma cetirizine concentrations with those obtained after application of liposomes containing 10 mg cetirizine, it is proposed that cetirizine in the liposomes may be concentrated in the skin, resulting in a reduction of the histamine-induced wheal reactions.
