3 PHARMACEUTICAL FORM

Clear colourless to pale yellow solution with a peach odour.
4 CLINICAL PARTICULARS
4.1 Therapeutic indications
Loratadine is indicated for the symptomatic treatment of allergic rhinitis and chronic idiopathic urticaria.
4.2 Posology and method of administration
Adults and children over 12 years of age: 10 mg once daily (10 ml (10 mg) of the syrup once daily). The syrup may be taken without regard to mealtime.
Children 2 to 12 years of age with:
Bodyweight more than 30 kg: 10 mg once daily (10 ml (10 mg) of the syrup once daily).
Bodyweight 30 kg or less: 5 ml (5 mg) of the syrup once daily.
Efficacy and safety of loratadine in children under 2 years of age has not been established.
Patients with severe liver impairment should be administered a lower initial dose because they may have reduced clearance of loratadine. An initial dose of 10 mg every other day is recommended for adults and children weighing more than 30 kg, and for children weighing 30 kg or less, 5 ml (5 mg) every other day is recommended.
No dosage adjustments are required in the elderly or in patients with renal insufficiency.
4.3 Contraindications
Loratadine is contraindicated in patients who are hypersensitive to the active substance or to any of the excipients in the formulation.
4.4 Special warnings and precautions for use
Loratadine should be administered with caution in patients with severe liver impairment (see section 4.2).
Loratadine Syrup contains 625 mg of sucrose per 1 ml; thus patients with rare hereditary problems of fructose intolerance, glucose-galactose malabsorption or sucrose isomaltase insufficiency should not take this medicine. This should also be taken into account in patients with diabetes mellitus.
The administration of loratadine should be discontinued at least 48 hours before skin tests since antihistamines may prevent or reduce otherwise positive reactions to dermal reactivity index.
4.5 Interaction with other medicinal products and other forms of interaction
When administered concomitantly with alcohol, loratadine has no potentiating effects as measured by psychomotor performance studies.
Potential interaction may occur with all known inhibitors of CYP3A4 or CYP2D6 resulting in elevated levels of loratadine (see section 5.2), which may cause an increase in adverse events.
4.6 Pregnancy and lactation
Loratadine was not teratogenic in animal studies. The safe use of loratadine during pregnancy has not been established. The use of loratadine during pregnancy is therefore not recommended.
Loratadine is excreted in breast milk, therefore the use of loratadine is not recommended in breast-feeding women.
4.7 Effects on ability to drive and use machines
In clinical trials that assessed driving ability, no impairment occurred in patients receiving loratadine. However, patients should be informed that very rarely some people experience drowsiness, which may affect their ability to drive or use machines.
4.8 Undesirable effects
In clinical trials in a paediatric population children aged 2 to 12 years, common adverse reactions reported in excess of placebo were headache (2.7%), nervousness (2.3%), and fatigue (1%).
In clinical trials involving adults and adolescents in a range of indications including AR and ClU, at the recommended dose of 10 mg daily, adverse reactions with loratadine were reported in 2 % of patients in excess of those treated with placebo. The most frequent adverse reactions reported in excess of placebo were somnolence (1.2%), headache (0.6%), increased appetite (0.5%) and insomnia (0.1%). Other adverse reactions reported very rarely during the post-marketing period are listed in the following table.

Overdose
4.9
Overdosage with loratadine increased the occurrence of anticholinergic symptoms. Somnolence, tachycardia, and headache have been reported with overdoses.
In the event of overdose, general symptomatic and supportive measures are to be instituted and maintained for as long as necessary. Administration of activated charcoal as a slurry with water may be attempted. Gastric lavage may be considered. Loratadine is not removed by haemodialysis and it is not known if loratadine is removed by peritoneal dialysis. Medical monitoring of the patient is to be continued after emergency treatment.
5 PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: antihistamines — H1 antagonist ATC code: R06A X13
Loratadine, the active ingredient in Loratadine Syrup, is a tricyclic antihistamine with selective, peripheral H1-receptor activity.
Loratadine has no clinically significant sedative or anticholinergic properties in the majority of the population and when used at the recommended dosage.
During long-term treatment there were no clinically significant changes in vital signs, laboratory test values, physical examinations or electrocardiograms.
Loratadine has no significant H2-receptor activity. It does not inhibit norepinephrine uptake and has practically no influence on cardiovascular function or on intrinsic cardiac pacemaker activity.
5.2 Pharmacokinetic properties
After oral administration, loratadine is rapidly and well absorbed and undergoes an extensive first pass metabolism, mainly by CYP3A4 and CYP2D6. The major metabolite - desloratadine (DL) - is pharmacologically active and responsible for a large part of the clinical effect. Loratadine and DL achieve maximum plasma concentrations (Tmax) between 1-1.5 hours and 1.5-3.7 hours after administration respectively.
An increase in the plasma concentrations of loratadine has been reported after concomitant use with ketoconazole, erythromycin, and cimetidine in controlled trials, but without clinically significant changes (including electrocardiographic).
Loratadine is highly bound (97 % to 99 %) and its active metabolite moderately bound (73 % to 76 %) to plasma proteins.
In healthy subjects, plasma distribution half-lives of loratadine and its active metabolite are approximately 1 and 2 hours, respectively. The mean elimination halflives in healthy adult subjects were 8.4 hours (range = 3 to 20 hours) for loratadine and 28 hours (range = 8.8 to 92 hours) for the major active metabolite.
Approximately 40% of the dose is excreted in the urine and 42% in the faeces over a 10 day period and mainly in the form of conjugated metabolites. Approximately 27% of the dose is eliminated in the urine during the first 24 hours. Less than 1% of the active substance is excreted unchanged in active form, as loratadine or DL.
The bioavailability parameters of loratadine and of the active metabolite are dose proportional.
The pharmacokinetic profile of loratadine and its metabolites is comparable in healthy adult volunteers and in healthy geriatric volunteers.
Concomitant ingestion of food can delay slightly the absorption of loratadine but without influencing the clinical effect.
ln patients with chronic renal impairment, both the AUC and peak plasma levels (Cmax) increased for loratadine and its metabolite as compared to the AUCs and peak plasma levels (Cmax) of patients with normal renal function. The mean elimination half-lives of loratadine and its metabolite were not significantly different from those observed in normal subjects. Haemodialysis does not have an effect on the pharmacokinetics of loratadine or its active metabolite in subjects with chronic renal impairment.
In patients with chronic alcoholic liver disease, the AUC and peak plasma levels (Cmax) of loratadine were double while the pharmacokinetic profile of the active metabolite was not significantly changed from that in patients with normal liver function. The elimination half-lives for loratadine and its metabolite were 24 hours and 37 hours, respectively, and increased with increasing severity of liver disease.
Loratadine and its active metabolite are excreted in the breast milk of lactating women.
5.3 Preclinical safety data
Preclinical data reveal no special hazard based on conventional studies of safety, pharmacology, repeated dose toxicity, genotoxicity and carcinogenic potential.
In reproductive toxicity studies, no teratogenic effects were observed. However, prolonged parturition and reduced viability of offspring were observed in rats at plasma levels (AUC) 10 times higher than those achieved with clinical doses.
