Olonase Nasal Spray 15ml

Olopatadine is a relatively selective histamine H1 antagonist and inhibitor of the release of histamine from the mast cells. Decreased chemotaxis and inhibition of eosinophil activation has also been demonstrated. Olopatadine is devoid of effect on alpha-adrenergic , dopaminergic, and muscarinic type 1 and 2 receptors.
