Uses

Antegy is used for symptomatic treatment of allergic rhino-conjunctivitis (seasonal and perennial) and urticaria.
Efficacy and safety of Antegy 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 Antegy should not be used in these age groups.

Antegy is also used to associated treatment for these conditions: Chronic Spontaneous Urticaria, Seasonal Allergic Rhinitis

How Antegy works

Antegy is a selective histamine H1 receptor antagonist (Ki = 64nM) . During allergic response mast cells undergo degranulation which releases histamine and other subastances. By binding to and preventing activation of the H1 receptor, bilastine reduces the development of allergic symptoms due to the release of histamine from mast cells.

Dosage

Antegy dosage

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 Antegy (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 Antegy tablet (1 tablet) once daily should be swallowed with water on an empty stomach to achieve optimal exposure to Antegy.

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.

Side Effects

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.

Toxicity

The most common adverse effects experienced during clinical trials were abdominal pain, dizziness, headache, and somnolence . Antegy is associated with Q/T prolongation. The no observed adverse effect level of bilastine is 1200 mg/kg/day in rats and 125 mg/kg/day in dogs .

Precaution

Co-administration of Antegy and P-glycoprotein inhibitors (e.g. Ketoconazole, Erythromycin, Cyclosporine, Ritonavir or Diltiazem) should be avoided in patients with moderate or severe renal impairment.

Interaction

Concomitant intake of Antegy and Ketoconazole or Erythromycin or Diltiazem increased C max of Antegy. The psychomotor performance after concomitant intake of alcohol and Antegy was similar to that observed after intake of alcohol and placebo. Concomitant intake of Antegy and Lorazepam 3 mg for 8 days did not potentiate the depressant CNS effects of Lorazepam.

Food Interaction

  • Take on an empty stomach. Take at least two hours before or one hour after eating.

Elimination Route

Antegy has a Tmax of 1.13 h . The absolute bioavailability is 61%. No accumulation observed with daily dosing of 20-100 mg after 14 days. Cmax decreased by 25 % and 33% when taken with a low fat and high fat meal compared to fasted state. Administration with grapefruit juice decreased Cmax by 30%.

Half Life

The mean half life of elimination is 14.5h .

Clearance

Antegy has a total clearance is 9.20 L/h and a renal clearance of 8.7 L/h .
