It works by the active ingredient, ipratropium bromide, attaching to acetylcholine receptors in the nasal passages. This blocks acetylcholine and reduces nasal secretions, which helps relieve congestion and breathing difficulties. Acetylcholine is a neurotransmitter that can trigger mucus production, so blocking it can be especially helpful for people with allergies or sinus issues.
