Rupatadine is indicated for the symptomatic treatment of seasonal & perennial allergic rhinitis and urticaria.
Rupatadine is a second generation, non-sedating, long-acting histamine antagonist with selective peripheral H1 receptor antagonist activity. It further blocks the receptors of the platelet-activating factor (PAF) according to in vitro and in vivo studies.
Rupatadine possesses anti-allergic properties such as the inhibition of the degranulation of mast cells induced by immunological and non-immunological stimuli, and inhibition of the release of cytokines, particularly of the tumor necrosis factors (TNF) in human mast cells and monocytes.
