10 ml drop: ৳ 80.00

Indications

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

Therapeutic Class

Ophthalmic Non-Steroid drugs

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.

Dosage & 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.

Interaction

Naphazoline containing products should not be administered during treatment with MAO-blockers nor during 10 days after discontinuation of such treatment. The effects of Naphazoline may be increased by concomitant use of tricyclic antidepressants.
