title: Inhibitory effect of hydroxyzine on antigen-induced histamine release in vivo.
abstract: By use of a modified heat-suction, skin blister technique, we found that oral hydroxyzine, 25 mg four times a day, inhibits antigen-induced ultrastructural changes of mast cells and in vivo histamine release in the skin of ragweed-sensitive individuals. To our knowledge this is the first demonstration that an orally active antihistamine can inhibit in vivo cutaneous anaphylactic reactions.
