Bilastine is an antiallergenic and acts to reduce allergic symptoms such as nasal congestion and urticaria Label.
- Mechanism of action
Bilastine is a selective histamine H1 receptor antagonist (Ki = 64nM) Label. 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.
Target Actions Organism AHistamine H1 receptor antagonistHumans - Absorption
Bilastine has a Tmax of 1.13 h Label. 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%.
- Volume of distribution
Not Available
- Protein binding
Bilastine is 84-90% bound to human plasma proteins Label.
- Metabolism
Bilastine does not interact with the cytochrome P450 system and does not undergo significant metabolism in humans Label.
- Route of elimination
Bilastine is mainly excreted in the feces (66.5%) with some excreted in the urine (28.3%) Label. Nearly all is excreted as the parent compound.
- Half-life
The mean half life of elimination is 14.5h Label.
- Clearance
Bilastine has a total clearance is 9.20 L/h and a renal clearance of 8.7 L/h Label.
