Abstract
Urticaria is a common skin disease, which, in its chronic form, is a very disturbing
condition. Because histamine is the best-documented chemical mediator of urticaria,
histamine1-antagonists are the mainstay of therapy. First-generation anti-histamines are limited
by their tendency to produce sedation and anticholinergic side effects. Most of the
newer second-generation antihistamines compare well with the earlier agents in efficacy
but are not limited by the same adverse side effects. Loratadine may be distinguished
from other second-generation antihistamines by its pharmacodynamics profile, as well
as its tolerability and safety.
