Abstract

We have studied a 50-year-old white man with chronic urticaria and angioedema who has responded to treatment with cimetidine alone for over 2 yr. In a double-blind, placebo-controlled study, cimetidine alone was at least as effective as chlorpheniramine in relief of urticaria and angioedema. Additionally, cimetidine significantly inhibited (p < 0.01) the wheal response to histamine when it was compared to placebo. The inhibition of wheal response to histamine by cimetidine was significantly higher (p < 0.05) than chlorpheniramine. The presence of predominantly H₂- rather than H₁-histamine receptors in the cutaneous blood vessels may be responsible for the therapeutic effects of cimetidine in this patient.
