Indications & Uses
Naphazoline + Zinc Sulfate eye drops are used for acute and chronic conjunctivitis that is not caused by infection, and for nonspecific irritation of the conjunctiva. They can also be used after bacterial or viral conjunctivitis has been treated successfully. The solution is also used for irrigation of the tear ducts.
Pharmacology
Zinc sulphate works through its zinc ions, which have an astringent effect. That means they seal the tissue, and they are also slightly antiseptic. Naphazoline narrows the blood vessels and lessens the inflammation and swelling of the conjunctiva. It belongs to the benzylimidazoline group, and it does this by binding directly to a-adrenergic receptor sites on unstriated muscle cells in the blood vessels.
