Metabolite Identification
Common NameBilastine
DescriptionBilastine, also known as bilanoa, belongs to the class of organic compounds known as benzimidazoles. These are organic compounds containing a benzene ring fused to an imidazole ring (five member ring containing a nitrogen atom, 4 carbon atoms, and two double bonds). Bilastine is a drug which is used for symptomatic relief of nasal and non-nasal symptoms of seasonal rhinitis in patients 12 years of age and older and for symptomatic relief in chronic spontaneous urticaria in patients 18 years of age and older [fda label]. Bilastine is a very strong basic compound (based on its pKa). In humans, bilastine is involved in bilastine h1-antihistamine action. The clinical efficacy of bilastine in allergic rhinitis (AR) and urticaria has been assessed in 10 clinical assays in which over 4,600 patients were involved. Phase II and III studies on AR and urticaria (including the open-label extension phase of 12 months) do not reveal alterations in the ECG, nor significant prolongations of the QTc interval after administration of bilastine 20 mg. No effects on fertility, no teratogenic or mutagenic effects, and no apparent carcinogenic potential were seen in the studies carried out in rats, mice and rabbits.
