Antazoline Sulfate

Antistine-Privine (Antazoline Sulfate) is a 1st generation antihistamine, with good anticholinergic properties. It is used to relieve nasal congestion and added in eye drops, usually in combination with naphazoline, to relieve the symptoms of allergic conjunctivitis.

Designed for biological research and industrial applications, not intended for individual clinical or medical purposes.
