Description

Loratadine is a non-sedating, inverse agonist antihistamine used for the treatment of allergic rhinitis, an IgE (immunoglobulin E) mediated disease. Loratadine binds to histamine H1 receptors, preventing histamine from binding and causing an allergic reaction.It has been found to inhibit the release of eosinophil cationic protein by acting on different components of allergic inflammation, in particular in the modulation of ICAM-1 expression on nasal epithelial cells as a mechanism of protective for the epithelium, and therefore, the damage of mucosa is reduced. In recent studies, it was found that loratadine is a potent HR1 antagonist with in vitro inhbitory effect on human mast-cell lines, HMC-1 (from mast cell leukaemia) with an IC50 between 10 and 50 μM.
