Pharmaceutical form :

Oral suspension.

Pharmacological action :

Pharmacodynamics: Fexofenadine is an antihistamine with selective peripheral H’l-receptor antagonist activity. Fexofenadine inhibited antigen-induced bronchospasm in sensitized guinea pigs and histamine release from peritoneal mast cells in rats. In laboratory animals, no anticholinergic or alpha l-adrenergic-receptor blocking effects were observed. Moreover, no sedative or other central nervous system effects were observed. Radiolabeled tissue distribution studies in rats indicated that fexofenadine does not cross the blood-brain barrier.

Pharmacokinetics :

Fexofenadine hydrochloride is rapidly absorbed following oral administration. Tmax occurred approximately 1-3 hours post dose. A 5 mL dose of suspension containing 30 mg of fexofenadine hydrochloride is bioequivalent to a 30 mg dose of fexofenadine hydrochloride tablets. Fexofenadine is 60% to 70% bound to plasma proteins.

Indications :

– Relief of symptoms associated with seasonal allergic rhinitis such as sneezing, itchy, runny or blocked nose/palate/throat, itchy/watery/red eyes
– Relief of symptoms associated with chronic idiopathic urticarial such as itch i ng, swell i ng a nd rashes.

Dosage and administration :

Pediatrics:
The recommended dose for seasonal allergic rhinitis is 30 mg twice daily in patients 2 toll years of age. The recommended dose for chronic idiopathic urticaria is 30 mg twice daily in patients 2 years to 11 years of age and 15 mg twice daily in patients 6 months to less than 2 years of age. The efficacy and safety of fexofenadine hydrochloride have not been established in children under 2 years of age for seasonal allergic rhinitis and under 6 months of age for chronic idiopathic urticaria.
Special Populations :
Studies in special risk groups (elderly, renally or hepatically impaired patients) indicate that it is not necessary to adjust the dose of fexofenadine hydrochloride in these patients.

Contraindications :

Telfast” is contraindicated in patients with known hypersensitivity to a ny of its i ngred ients.

Side Effects :

In placebo-controlled trials involving seasonal allergic rhinitis and chronic idiopathic urticaria patients, adverse events were comparable in fexofenadine- and placebo treated patients. The most frequent adverse events reported with fexofenadine include: > 3%: headache, 1-3%: drowsiness, dizziness and nausea.
Events that have been reported during controlled trials involving seasonal allergic rhinitis and chronic idiopathic urticaria patients with incidences less than 1% and similar to placebo and have been reported rarely during postmarketing surveillance include: fatigue, insomnia, nervousness, and sleep disorders or paroniria. In rare cases, rash, urticaria, pruritus and hypersensitivity reactions with manifestations such as angioedema, chest tightness, dyspnea, flushing and systemic anaphylaxis have been reported. In placebo-controlled trials involving pediatric seasonal allergic rhinitis patients (6-11years of age), adverse events were similar to those
observed in trials involving seasonal allergic rhinitis patients 12 years and older.
In controlled clinical trials involving pediatric patients 6 months to 5 years of age, there were no unexpected adverse events in patients treated with fexofenadine hydrochloride.

Drug Interactions :

The coadministration of Telfast” with erythromycin or ketoconazole resulted in no significant increases in QTc. No differences in adverse effects were reported whether these agents were administered alone or in combination.
Administration of an antacid containing aluminum and magnesium hydroxide gels 15 minutes prior to fexofenadine hydrochloride caused a reduction in bioavailability. It is advisable to leave 2 hours between administration of fexofenadine hydrochloride and aluminum and magnesium containing antacids.
No interaction between fexofenadine and omeprazole was observed.
