Naphazoline nitrate（Cat No.:I011964）is a vasoconstrictor commonly used in topical formulations to relieve symptoms of nasal congestion and eye irritation. As an adrenergic agonist, it works by stimulating alpha-adrenergic receptors, causing blood vessels to constrict, reducing swelling and congestion in the nasal passages or eyes. Naphazoline nitrate is typically found in over-the-counter nasal sprays and eye drops, offering temporary relief from conditions like allergic rhinitis or conjunctivitis. While effective for short-term use, prolonged or excessive use may lead to rebound congestion or irritation, so it is recommended for occasional use only.
