Bilastine is indicated for symptomatic treatment of allergic rhino-conjunctivitis (seasonal and perennial) and urticaria.
Bilastine is a non-sedating, long-acting histamine antagonist with selective peripheral H 1 receptor antagonist affinity and no affinity for muscarinic receptors. Bilastine inhibits histamine-induced wheal and flare skin reactions for 24 hours following single doses.
Dosage & Administration
Adults & adolescents (12 years of age and over): 20 mg tablet once daily for symptomatic relief of allergic rhinitis, urticaria and allergic rhinoconjunctivitis. The maximum recommended daily dose is 20 mg Bilastine (1 tablet) and should not be exceeded. If a dose is missed, the next scheduled dose should be taken. An extra dose should not be taken. 20 mg Bilastine tablet (1 tablet) once daily should be swallowed with water on an empty stomach to achieve optimal exposure to Bilastine.
Children between 6 to 11 years: 10 mg mouth dissolving tablet for the symptomatic relief of allergic rhinitis, allergic rhinoconjunctivitis and urticaria. The Mouth dissolving tablet is for oral use only. It should be placed in the mouth. It will disperse rapidly in saliva and can be easily swallowed. Alternatively, the mouth dissolving tablet can be dispersed in a tea spoon of water before being swallowed by the children. The maximum recommended daily dose for children in between 6 to 11 years is 10 mg Bilastine mouth dissolving tablet (1 tablet) and should not be exceeded. If a dose is missed, the next scheduled dose should be taken. An extra dose should not be taken.
Children between 2 to 11 years: 4 ml once daily.
Concomitant intake of Bilastine and Ketoconazole or Erythromycin or Diltiazem increased C max of Bilastine. The psychomotor performance after concomitant intake of alcohol and Bilastine was similar to that observed after intake of alcohol and placebo. Concomitant intake of Bilastine and Lorazepam 3 mg for 8 days did not potentiate the depressant CNS effects of Lorazepam.
Bilastine is contraindicated in patients with hypersensitivity to the active substance or to any of the excipients of the tablet.
The most commonly reported side effects in clinical trial are headache, dizziness, somnolence and fatigue. These adverse events occurred with a comparable frequency in patients receiving placebo.
Pregnancy & Lactation
There are no or limited amount of data from the use of Bilastine in pregnant women. Animal studies do not indicate direct or indirect harmful effects with respect to reproductive toxicity, parturition or postnatal development. As a precautionary measure, it is preferable to avoid the use of Bilastine during pregnancy. The excretion of Bilastine in milk has not been studied in humans. A decision must be made taking into account the benefit of breast-feeding for the child and the benefit of Bilastine therapy for the mother.
Precautions & Warnings
Co-administration of Bilastine and P-glycoprotein inhibitors (e.g. Ketoconazole, Erythromycin, Cyclosporine, Ritonavir or Diltiazem) should be avoided in patients with moderate or severe renal impairment.
Use in Special Populations
Efficacy and safety of Bilastine in children under 2 years of age have not been established and there is little clinical experience in children aged 2 to 5 years, therefore Bilastine should not be used in these age groups.
In clinical trials, after administration of Bilastine at doses 10 to 11 times the therapeutic dose (220 mg as single dose; or 200 mg/day for 7 days) frequency of treatment-emergent adverse events was two times higher than with placebo. The adverse reactions most frequently reported were dizziness, headache and nausea. No serious adverse events and no significant prolongation in the QTc interval were reported.
Keep below 30°C temperature, protected from light and moisture. Keep out of reach of children.
