PHARMACOLOGY
Alatrol®
is a potent H1 receptor antagonist without any significant
anticholinergic and antiserotonic effects. At pharmacologically
active dose levels, it has almost no drowsiness effect and does not
cause behavioral changes which may be explained by the absence
of passage through the blood brain barrier. Alatrol®
inhibits the
histamine mediated early phase of the allergic reaction and also
reduces the migration of inflammatory cells and the release of
mediators associated with the late phase of the allergic reaction.
Alatrol®
also provides a protective effect from bronchospasm
induced by inhaled histamine in asthmatics. Alatrol®
absorbs very
rapidly. Plasma half-life of Cetirizine is 6.7 to 10.90 hours.
INDICATION
Seasonal Allergic Rhinitis: Alatrol®
is indicated for the relief of
symptoms associated with seasonal allergic rhinitis due to
allergens such as ragweed, grass and tree pollens. Symptoms
treated effectively include sneezing, rhinorrhea, pruritus, ocular
pruritus, tearing and redness of the eyes. Perennial Allergic Rhinitis:
Alatrol®
is indicated for the relief of symptoms associated with
perennial allergic rhinitis due to allergens such as dust, mites,
animal dander, and molds. Symptoms treated effectively include
sneezing, rhinorrhea, post-nasal discharge, nasal pruritus, ocular
pruritus and tearing. Chronic Idiopathic Urticaria: Alatrol®
is
indicated for the treatment of the uncomplicated skin
manifestations of chronic idiopathic urticaria. It significantly

teaspoonful) twice daily. In patients with decreased renal function
(Creatinine clearance 11-31 ml/min), patients on hemodialysis

impaired patients, a dose of 1/2 tablet or 5 ml (1 teaspoonful) once
daily is recommended.

necessary in patients with moderate or severe renal impairment,
hepatic impairment and patients on dialysis.
PRECAUTION
Caution should be exercised when driving a car or operating a
heavy machinery. Concurrent use of Cetirizine with alcohol or
other CNS depressants should be avoided because additional
reduction in alertness and additional impairment of CNS
performance may occur.
DRUG INTERACTION
No clinically significant drug interactions have been found with
theophylline, azithromycin, pseudoephedrine, ketoconazole or
erythromycin and with other drugs.
SIDE EFFECT
Cetirizine seems to cause an incidence of sedation similar to that
observed with placebo and with other non-sedating
antihistamines such as astemizole and terfenadine and causes a
lower incidence of sedation than that with ketotifen, clemastine,
pheniramine, chlorpheniramine or mequitazine. Cetirizine does
not cause anticholinergic effects.
CONTRAINDICATION
Cetirizine is contraindicated in patients who have shown
hypersensitivity or idiosyncrasy to cetirizine or to its parent
compound, hydroxyzine.
USE IN PREGNANCY AND LACTATION
Pregnancy category B. Cetirizine should be used in pregnancy
only if clearly needed. Cetirizine has been reported to be
excreted in human milk and thus, use of Cetirizine in lactating
mother is not recommended.
