CETIRIZINE DIHYDROCHLORIDE 10 MG FILM-COATED TABLETS
PL 33410/0043 & PL 33410/0062
LAY SUMMARY
The Medicines and Healthcare products Regulatory Agency (MHRA) granted APSLA
Limited Marketing Authorisations (licences) for the medicinal product Cetirizine
Dihydrochloride 10 mg Film-Coated Tablets (PL 33410/0043 and PL 33410/0062) on
9 June 2011.
The products are available in numerous pack sizes and presentations. Pack sizes of up to
and including 14 tablets are available on the General Sales List (GSL), and can be
purchased at pharmacies, supermarkets and other retail outlets without the supervision of a
pharmacist. Pack sizes of up to and including 60 tablets are P licensed medicines available
only from pharmacies, under the supervision of a pharmacist.
Cetirizine dihydrochloride is an antiallergic medication. In adults and children aged 6 years
and above cetrizine dihydrochloride is used to treat the symptoms of hayfever (allergic
rhinitis) and year round allergies such as dust or pet allergies (perennial allergic rhinitis), as
well as the relief of swelling, redness and itchiness of the skin.
No new or unexpected safety concerns arose from these applications and it was, therefore,
judged that the benefits of taking Cetirizine Dihydrochloride 10 mg Film-Coated Tablets
outweigh the risks; hence Marketing Authorisations have been granted.

INTRODUCTION
The UK granted Marketing Authorisations for the medicinal product Cetirizine
Dihydrochloride 10 mg Film-Coated Tablets (PL 33410/0043) and its duplicate licence
(PL 33410/0062) to APSLA Limited on 9 June 2011.
Cetirizine Dihydrochloride 10 mg Film-Coated Tablets (PL 33410/0043) is available as a
pharmacy only medicine under the supervision of a pharmacist. Cetirizine Dihydrochloride
10 mg Film-Coated Tablets (PL 33410/0062) is available as a GSL product and is sold
without the supervision of a pharmacist in pack sizes of no greater than 14 tablets.
Cetirizine Dihydrochloride 10mg Film-Coated Tablets are for the symptomatic relief of
perennial rhinitis, seasonal allergic rhinitis and idiopathic chronic urticaria in adults and
children aged 6 years and over.
These are generic applications for Cetirizine Dihydrochloride 10 mg Film-Coated Tablets,
submitted under Article 10(1) of Directive 2001/83/EC, as amended. The applications refer
to the UK reference (innovator) product, Zirtek 10mg, originally licensed to UCB S.A
(PL 05221/0001) on 16 August 1988. The reference licence has since undergone two
Change of Ownership (CoA) procedures; the first to UCB Waterford Limited on 23 March
2000 and subsequently to the current Marketing Authorisation Holder (MAH), UCB
Pharma Limited UK (PL 00039/0542) on 12 December 2005. The second change of
ownership resulted in separate licences being created for Pharmacy supply
(PL 00039/0542) and GSL (Zirtek Allergy Relief/Zirtek Allergy 10mg Tablets
(PL 00039/0561). The reference product has been authorised in the EEA for over 10 years.
The Marketing Authorisation Holder has provided adequate justification for not submitting
an Environmental Risk Assessment (ERA). Cetirizine Dihydrochloride is a wellestablished active substance that has had widespread clinical used for many years. These
were applications for generic products, which will not be administered at a higher dosage,
for a longer duration or for different indications that were previously authorised. There is
no reason to conclude that marketing of these products will change the overall use pattern
of the existing market.
The pharmacovigilance system, as described by the MAH, fulfils the requirements and
provides adequate evidence that the MAH has the services of a qualified person responsible
for pharmacovigilance and has the necessary means for the notification of any adverse
reaction suspected of occurring either in the Community or in a third country.
The MAH has provided adequate justification for not submitting a Risk Management Plan
(RMP). As the application is for a generic version of an already authorised reference
product, for which safety concerns requiring additional risk minimisation have not been
identified, a risk minimisation system is not considered necessary. The reference product
has been in use for many years and the safety profile of the active is well established.
No new pre-clinical or clinical studies were performed, which is acceptable given that the
proposed product is a generic medicinal product of the reference product that have been
licensed for over 10 years.

CLINICAL ASSESSMENT
Pharmacokinetics
In support of this application, the marketing authorisation holder has submitted the
following bioequivalence study. The reference product used for the bioequivalence study is
Zirtek Allergy 10 mg Tablets (PL 00039/0542), UCB Pharma Limited UK.
This is a single dose, randomised, balanced, two-way crossover comparative oral
bioavailability study of Cetirizine Dihydrochloride 10 mg Film-Coated Tablets(test
product) and Zirtek Allergy 10 mg Tablets (UCB Pharma Limited, UK) in healthy adults
under fasting conditions.
The study was conducted in compliance with Good Clinical Practice (ICH-GCP) and Good
Laboratory Practice.
Study design
A single dose of the investigational products (1 tablet of 10mg) was administered orally to
each subject in each period with 240 ml of water after an overnight fast of at least 10 hours.
Serial blood sampling before dosing and up to 48hours after drug administration was
carried out.
A washout period of 7 days was maintained between the two dosing periods in each group
which is sufficient time for cetirizine dihydrochloride to be eliminated from the body.
A validated HPLC-MS/MS analytical methodology was used for quantification of
Cetirizine dihydrochloride from the human plasma samples. Primary variables analysed
were: Cmax, AUC0-t and AUC0-∞ and additional pharmacokinetic parameters were tmax, t1/2,
MRT and AUC% Extrap.
Results
All volunteers completed both treatment periods and their data were included in the
statistical analysis.
There were no protocol deviations.
Baseline plasma levels were zero at period 2, indicating that the washout period was
adequate.
The results are summarised in Tables 1 and 2.

4.4
Special warnings and precautions for use
The use of the film-coated tablet formulation is not recommended in children aged less than 6 years
since this formulation does not allow for appropriate dose adaptation.
Do not exceed the stated dose. If symptoms persist consult your doctor.
4.5
Interaction with other medicinal products and other forms of interaction
To date there have been no known interactions with other drugs. Studies with diazepam and
cimetidine revealed no evidence of interactions. As with other antihistamines, it is advisable to avoid
excessive alcohol consumption.
At therapeutic doses, no clinically significant interactions have been demonstrated with alcohol (for
a blood alcohol level of 0.5 g/L). Nevertheless, precaution is recommended if alcohol is taken
concomitantly.
The extent of absorption of cetirizine is not reduced with food, although the rate of absorption is
decreased.
4.6
Pregnancy and lactation
No adverse effects have been reported from animal studies. There has been little or no clinical
experience of cetirizine in pregnancy. As with other drugs the use of cetirizine in pregnancy should
be avoided. Cetirizine is contraindicated in lactating women as it is excreted in breast milk.
4.7
Effects on ability to drive and use machines
Antihistamines can cause drowsiness in some patients. Although this has not been reported with
cetirizine at the recommended dose, please be cautious whilst driving or operating machinery.
4.8
Undesirable effects
Clinical studies have shown that cetirizine at the recommended dosage has minor undesirable effects
on the CNS, including somnolence, fatigue, dizziness and headache. In some cases, paradoxical CNS
stimulation has been reported.
Although cetirizine is a selective antagonist of peripheral H1-receptors and is relatively free of
anticholinergic activity, isolated cases of micturition difficulty, eye accommodation disorders and
dry mouth have been reported.
Instances of abnormal hepatic function with elevated hepatic enzymes accompanied by elevated
bilirubin have been reported. Mostly this resolves upon discontinuation of the treatment with
cetirizine dihydrochloride.
Post-marketing experience
The following adverse drug reactions have been reported from postmarketing experience.
Very common (≥1/10); common (≥1/100 to ≤1/10); uncommon (≥1/1,000 to ≤1/100); rare
(≥1/10,000 to ≤1,000); very rare (≤1/10,000), not known, cannot be estimated from available data.

General disorders and administration site conditions:
Uncommon: asthenia, malaise
Rare: oedema
Investigations:
Rare: weight increased
4.9
Overdose
Symptoms
Symptoms observed after an overdose of cetirizine are mainly associated with CNS effects or with
effects that could suggest an anticholinergic effect.
Adverse events reported after an intake of at least 5 times the recommended daily dose are:
confusion, diarrhoea, dizziness, fatigue, headache, malaise, mydriasis, pruritus, restlessness,
sedation, somnolence, stupor, tachycardia, tremor, and urinary retention.
Management
There is no known specific antidote to cetirizine.
Should overdose occur, symptomatic or supportive treatment is recommended. The patient should be
kept under clinical observationfor at least 4 hours after ingestion, and his blood pressure, heart rate
and vital signs monitored until stable. In symptomatic cases ECG should be performed. The benefit
of gastric lavage is uncertain.oral activated charcoal (50g for an adult, 10-15g for a child) should be
considered if more than 2.5mg/kg cetirizine has been ingested within 1 hour. Cetirizine is not
effectively removed by dialysis.

PHARMACOLOGICAL PROPERTIES
Pharmacodynamic properties
Pharmacotherapeutic group: Piperazine derivatives, ATC code: R06A E07
Cetirizine is a potent antihistamine with a low potential for drowsiness at normal therapeutic doses
which has additional anti-allergic properties. It is a selective H1 antagonist with negligible effects on
other receptors and so is virtually free from anti-cholinergic and anti-serotonin effects. Cetirizine

PL 33410/0062
inhibits the histamine-mediated early phase of the allergic-reaction and also reduces the migration of
certain inflammatory cells and the release of certain mediators associated with the late allergic
response.
5.2
Pharmacokinetic properties
Peak blood levels of the order of 0.3micrograms/ml are reached between 30 and 60 minutes after
oral administration of a 10mg dose of cetirizine. The terminal half-life is approximately ten hours in
adults, approximately six hours in children aged between 6 to12 years and approximately 5 hours in
children 2-6years.
This is consistent with the urinary excretion half life of the drug. The cumulative urinary excretion
represents about two thirds of the administered dose for both adults and children.
The apparent plasma clearance in children is higher than that measured in adults. A high proportion
of cetirizine is bound to human plasma proteins.
5.3
Preclinical safety data
Non-clinical data reveal no special hazard for humans based on conventional studies of safety
pharmacology, repeated dose toxicity, genotoxicity, carcinogenic potential, toxicity to reproduction.
