Desloratadine is a potent and selective histamine H1-receptor agonist with a half life of 21-24 hours. Experiments suggest that this compound also exerts antioxidant effects in vitro. Other studies show that H1-receptor binding by Desloratadine is reversible and that, over time, it dissociates from membrane H1-recepters. Desloratadine has also demonstrated the ability to block ICAM-1 upregulation and NFkappaB activation in primary bronchial and transformed respiratory epithelial cells in vitro.
