RUPATADINE Oral solution Ref.[7356] Active ingredients: Rupatadine

Safety of rupatadine oral solution in children aged less than 2 years has not been established.

The combination of rupatadine with potent CYP3A4 inhibitors should be avoided and with moderate CYP3A4 inhibitors should be administered with caution (see section 4.5).

Dose adjustment of sensitive CYP3A4 substrates (e.g. simvastatin, lovastatin) and CYP3A4 substrates with a narrow therapeutic index (e.g. cyclosporin, tacrolimus, sirolimus, everolimus, cisapride) could be required as rupatadine may increase plasma concentrations of these drugs (see section 4.5).

The administration of rupatadine with grapefruit juice is not recommended (see section 4.5).

Cardiac safety of rupatadine 10 mg tablets was assessed in a Thorough QT/QTc study in adults. Rupatadine up to 10 times therapeutic dose did not produce any effect on the ECG and hence raises no cardiac safety concerns. However, rupatadine should be used with caution in patients with known prolongation of the QT interval, patients with uncorrected hypokalemia, patients with ongoing proarrhythmic conditions, such as clinically significant bradycardia, acute myocardial ischemia.

Increases of blood creatine phosphokinase, alanine aminotransferase and aspartate aminotransferase, as well as abnormalities of liver function tests are uncommon adverse reaction reported with rupatadine 10 mg tablets in adults.

This medicinal product contains sucrose, so it may be harmful to the teeth.Patients with rare hereditary problems of fructose intolerance, glucose/galactose malabsorption or sucrase-isomaltase insufficiency should not take this medicine.

This medicinal product contains methyl parahydroxybenzoate, may cause allergic reactions (possibly delayed).

No interaction studies have been performed in children with rupatadine oral solution.

Interaction studies have only been performed in adults and adolescents (over 12 years of age) with rupatadine 10 mg tablets.

Effects of other drugs on rupatadine

Co-administration with potent CYP3A4 inhibitors (e.g. itraconazole, ketoconazole, voriconazole, posaconazole, HIV protease inhibitors, clarithromycin, nefazodone) should be avoided and co-medication with moderate CYP3A4 inhibitors (erythromycin, fluconazole, diltiazem) should be used with caution.

The concomitant administration of rupatadine 20 mg and ketoconazole or erythromycin increases the systemic exposure to rupatadine 10 times and 2-3 times respectively. These modifications were not associated with an effect on the QT interval or with an increase of the adverse reactions in comparison with the drugs when administered separately.

Interaction with grapefruit

The concomitant administration of grapefruit juice increased 3.5 times the systemic exposure of rupatadine 10 mg tablet. This occurs because grapefruit has one or more compounds that inhibit the CYP3A4 and can increase the plasmatic concentrations of drugs metabolised through this CYP3A4, like rupatadine. In addition, it has been suggested that the grapefruit can affect intestinal drug transport systems as the glycoprotein-P.Grapefruit juice should not be taken simultaneously.

Effects of rupatadine on other drugs

Caution should be taken when rupatadine is co-administered with other metabolised drugs with narrow therapeutic windows since knowledge of the effect of rupatadine on other drugs is limited.

Interaction with alcohol

After administration of alcohol, a dose of rupatadine 10 mg tablet produced marginal effects in some psychomotor performance tests although theywere not significantly different from those induced by intake of alcohol only. A dose of 20 mg increased the impairment caused by the intake of alcohol.

Interaction with CNS depressants

As with other antihistamines, interactions with CNS depressants cannot be excluded.

Interaction with statins

Asymptomatic CPK increases have been uncommonly reported in rupatadine clinical trials. The risk of interactions with statins, some of which are also metabolised by the cytochrome P450 CYP3A4 isozyme, is unknown. For these reasons, rupatadine should be used with caution when it is coadministered with statins.

Pregnancy

Data on a limited number (2) of exposed pregnancies indicate no adverse effects of rupatadine on pregnancy or on the health of the foetus/newborn child. To date, no other relevant epidemiological data are available. Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryonal/foetal development, parturition or postnatal development (see section 5.3). As a precautionary measure, it is preferable to avoid the use of rupatadine during pregnancy.

Breastfeeding

Rupatadine is excreted in animal milk. It is unknown whether rupatadine is excreted into breast milk. A decision must be made whether to discontinue breastfeeding or to discontinue/abstain from rupatadine therapy taking into account the benefit of breastfeeding for the child and the benefit of therapy for the woman.

Fertility

There are no clinical data on fertility. Studies in animals have shown a significant reduction of fertility at exposure levels higher than those observed in humans at the maximum therapeutic dose (see section 5.3).

Rupatadine 10 mg had no influence on the ability to drive and use machines in a performed clinical trial. Nevertheless, care should be taken before driving or using machinery until the patient’s individual reaction to rupatadine has been established.

Clinical trials with rupatadine oral solution in children aged 2-11 years included 626 patients. From these, 147 patients were treated with rupatadine 2.5 mg, 159 patients were treated with rupatadine 5 mg, 249 received placebo and 71 received desloratadine.

The frequencies of adverse reactions are assigned as follows: Common (≥1/100 to <1/10), Uncommon (≥1/1000 to <1/100).

The frequencies of adverse reactions reported in patients treated with rupatadine oral solution during clinical trials were as follows:

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 national reporting system.
