IMPURITIES AVAILABLE FOR 'Astemizole'

Omsynth Lifesciences Pvt. Ltd. is one of the leading manufacturer and exporter of Astemizole. Astemizole is a long-acting, second-generation antihistamine previously used to treat allergic conditions such as rhinitis and urticaria. It works by selectively blocking H₁ histamine receptors, thereby reducing allergy symptoms like sneezing, itching, and runny nose. Unlike first-generation antihistamines, astemizole has minimal sedative effects due to its limited ability to cross the blood-brain barrier. It is taken orally and has a prolonged duration of action, often requiring only once-daily dosing. However, astemizole was withdrawn or restricted in many countries due to its potential to cause serious cardiac arrhythmias, including QT interval prolongation and torsades de pointes, especially when combined with certain drugs or in cases of liver dysfunction. It is no longer widely used but remains a subject of pharmacological research. Buy high quality Astemizole from Omsynth Lifesciences.
