Common Name | desmethylastemizole |
---|
Description | desmethylastemizole 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). desmethylastemizole is a very strong basic compound (based on its pKa). It has been withdrawn from the market in most countries because of rare but potentially fatal side effects. desmethylastemizole is a metabolite of astemizole. Astemizole (R43512, marketed under the brand name Hismanal) was a second generation antihistamine drug which has a long duration of action. Astemizole was discovered by Janssen Pharmaceutica in 1977. |
