Antazol Plus is a combination nasal spray formulated to provide relief from allergic rhinitis accompanied by nasal congestion. It combines the anti-allergic properties of Sodium Cromoglicate, which stabilizes mast cells and prevents the release of histamine, with the decongestant effects of Xylometazoline Hydrochloride, a sympathomimetic agent that constricts nasal blood vessels to reduce swelling and congestion.
