1. CETRIZINE

3. MECHANISM OF
ACTION
Cetirizine competes with histamine for
binding at H1-receptor sites on the
effector cell surface, resulting in
suppression of histaminic edema, flare,
and pruritus.
Cetirizine is a non-sedating antihistamine
that works by blocking histamine (H-1)
receptors on cells.
 It is similar to the other second
generation antihistamines

4. DESCRIPTION
A potent second-generation histamine
H1 antagonist that is effective in the
treatment of allergic rhinitis, chronic
urticaria, and pollen-induced asthma.
Unlike many traditional antihistamines,
it does not cause drowsiness or
anticholinergic side effects.
Cetirizine and other second-generation
antihistamines do not readily enter the
brain from the blood, and, therefore,
they cause less drowsiness.
