4 CLINICAL PARTICULARS

4.1 Therapeutic indications

Symptomatic treatment of allergic rhinitis in adults, adolescents and children 6 years and older.

4.2 Posology and method of administration s

o

l

o

g y

Adults and adolescents 12

years and older:

2 sprays in each nostril once a day. In some cases 2 sprays in each nostril twice a day may be required. The maximum daily dose is 2 sprays in each nostril twice daily.

Children 6

to 11 years:

1 spray in each nostril

twice daily.

Clinical experience of up to 4 weeks duration showed good efficacy and safety in children. Longer experiences in children have not been available; however, clinical trials of up to one year duration using a double higher daily dose showed good safety in adults and adolescents.

Rhinolast S 0.15% Nasal Spray is not recommended for use in children below 6 years of age due to a lack of data on safety and/or efficacy.

Duration of

treatment

Rhinolast S 0.15% Nasal Spray is suitable for long-term use. The duration of treatment should be a clinical decision considering the severity of allergic symptoms, safety and should correspond to the period of allergenic exposure.

Use longer than 4 weeks is not recommended in children 6–11 years due to lack of clinical data.

Method of administration

Nasal use

Precautions to be taken before handling or administering the medicinal product:

Spray with had help upright.

Before the first use, the pump must be primed by pressing down and releasing the pump six times. When Rhinolast S 0.15% Nasal Spray has not been used for 3 or more days, the pump must be reprimed by pressing down and releasing the pump a sufficient number of times until a fine mist emerges.

4.3 Contraindications

Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

4.4 Special warnings and precautions for use

Nothing relevant

4.5 Interaction with other medicinal products and other forms of interaction

No interaction studies with azelastine nasal spray have been performed. Interaction studies at high oral doses have been performed. However, they bear no relevance to Rhinolast S 0.15% Nasal Spray as systemic levels after administration reach no more than 1/5 of the levels that were well tolerated after oral administration.

4.6 Fertility, Pregnancy and lactation

Pregnancy

There are no or limited amount of data from the use of azelastine in pregnant women. At high oral doses reproductive toxicity has been seen in animals (see section 5.3).

Therefore, caution should be exercised when using Rhinolast S 0.15% Nasal Spray during pregnancy.

Breastfeeding

It is unknown whether azelastine/me­tabolites are excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when azelastine is administered to a nursing woman.

Fertility

Effects on fertility were seen in animal studies (see section 5.3).

4.7 Effects on ability to drive and use machines

Rhinolast S 0.15% Nasal Spray has minor influence on the ability to drive and use machines.

Rarely, the patient may experience fatigue, weariness, exhaustion, dizziness or weakness due to the disease itself, or when using Rhinolast S 0.15% Nasal Spray. In these cases, the ability to drive and use machines may be impaired. Special attention should be paid to the fact that alcohol may enhance these effects.

4.8 Undesirable effects

Commonly, dysgeusia, a substance-specific unpleasant taste, may be experienced after administration (often due to incorrect method of application, namely tilting the head too far backwards during administration) which, in rare cases, may lead to nausea.

Adverse events are listed below by system organ class and frequency. Frequencies are defined as:

Very common (> 1/10);

Common (> 1/100 to < 1/10); Uncommon (> 1/1,000 to < 1/100);

Rare (> 1/10,000 to < 1/1,000);

Very rare (< 1/10,000),

not known (cannot be estimated from the available data).

** may also be caused by the disease itself (see section 4.7)

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.go.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.

4.9

Overdose

With the nasal route of administration overdose reactions are not anticipated. In the event of overdose after incidental oral uptake, disturbances of the central nervous system (including drowsiness, confusion, coma, tachycardia and hypotension) are to be expected based on the results of animal experiments. Treatment of these disorders must be symptomatic. Depending on the amount swallowed gastric lavage is recommended. There is no known antidote.

5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Nasal preparations, decongestants and other nasal preparations for topical use, antiallergic agents, excl. corticosteroids.

ATC code: R01AC03

Azelastine, a phthalazinone derivative is classified as a potent long-acting antiallergic compound

with selective H1-antagonist properties. An additional anti-inflammatory effect could be detected after topical ocular administration.

Data from in vivo (pre-clinical) and in vitro studies show that azelastine inhibits the synthesis or release of the chemical mediators known to be involved in early and late stage allergic reactions, e.g. leukotrienes, histamine, PAF and serotonin.

Data from clinical studies show that azelastine nasal spray has a faster onset of action than desloratadine and nasally administered mometasone. A relief of nasal allergic symptoms is observed within 15 minutes after administration.

5.2 Pharmacokinetic properties

General characteristics:

Following oral administration, azelastine is rapidly absorbed showing an absolute bioavailability of 81 %. Food has no influence on absorption. The volume of distribution is high indicating distribution predominantly to the peripheral tissues. The level of protein binding is relatively low (80 %-90 %, a level too low to give concern over drug displacement reactions).

Plasma elimination half-lives after a single dose of azelastine are approximately 20 hours for azelastine and about 45 hours for the therapeutically active metabolite N-desmethyl azelastine. Excretion occurs mainly via the faeces. The sustained excretion of small amounts of the dose in the faeces suggests that some entero-hepatic circulation takes place.

After intranasal administration of 2 sprays per nostril (0.822 mg total dose) of Rhinolast S 0.15% Nasal Spray, the mean azelastine peak plasma concentration (Cmax) is 409 pg/ml in healthy subjects, the mean extent of systemic exposure (AUC) is 9312 pg^hr/ml and the median time to reach Cmax (tmax) is 4 hours.

5.3 Preclinical safety data

Azelastine hydrochloride displayed no sensitising potential in the guinea pig.

Azelastine demonstrated no genotoxic potential in a battery of in vitro and in vivo tests, nor any carcinogenic potential in rats or mice. In male and female rats, azelastine at oral doses greater than 3.0 mg/kg/day caused a dose-related decrease in the fertility index; no substance-related alterations were found in the reproductive organs of males or females during chronic toxicity studies. Embryotoxic and teratogenic effects in rats, mice and rabbits occurred only at maternal toxic doses (for example in mice and rats at doses of 68.6 mg/kg/day).

At high oral doses in animals, 1095 times the maximum recommended intranasal human daily dose, foetal death, growth retardation and an increased incidence of skeletal abnormalities occurred during reproduction toxicity testing.
