Administration

Adults: 1 drop in the conjunctival sac, three to 4 times per day.

Children: Naphazoline nitrate and Zinc sulphate drops has not been studied in children. Generally, in children the dosage of vasoconstrictors should be low and selected with caution.

Effects

Mydriasis and a slight increase of intraocular pressure in isolated cases. A slight and transient burning sensation may occur after instillation, which does not affect the success of the treatment. Long term use may result in reactive redness of the eye (rebound effect).

In very rare cases systemic cardiovascular effects, such as hypertension and arrhythmia, may occur. Nonspecific fatigue has been observed in some patients.

Indications

Acute and chronic non-infectious conjunctivitis, nonspecific conjunctival irritation; also after successful treatment of bacterial and viral conjunctivitis. Irrigation of the tear ducts.

Pharmacology

Zinc ions, the active compound of zinc sulphate, have an astringent, i.e. tissue-sealing and slightly anti-septic effect. Naphazoline constricts the blood vessels and reduces the inflammation and swelling of the conjunctiva. This effect of naphazoline, a substance of the benzylimidazoline group, is due to direct binding to a-adrenergic receptor sites on unstriated muscle cells in the blood vessels.

Precautions

Uncontrolled use of Naphazoline & Zinc over extended periods of time should be avoided. If no improvement is seen after 2 days, treatment should be discontinued and other therapeutic measures should be considered. If ocular discomfort or visual disturbance occurs during Naphazoline & Zinc treatment, the therapy must be discontinued. Caution is indicated in patients with predisposition to glaucoma and in patients suffering from hypertension, cardiovascular diseases, pheochromocytoma, aneurysm, hyperglycemia, and hyperthyroidism.
