Opthamet Ophthalmic Solution

Temporary relief of the signs and symptoms of allergic conjunctivitis including conjunctival hyperaemia, chemosis and itching in adults and children above 2 years of age.

Antazoline is an anti-histamine of the ethylenediamine class, which are selective HI-antagonist. Effects mediated by HI receptors include the contraction of smooth muscle and the dilation and increased permeability of the capillaries. Tetryzoline is a sympathomimetic with alpha-adrenergic activity. Its vasoconstrictive effect reduces redness and edema in allergic conjunctivitis. Antihistamines, which act by blocking the HI histamine receptor, are highly effective in providing relief of itching but are not very active in relieving the associated redness. The use of products combining an anti-histamine and a vasoconstrictor is well established in the symptomatic relief of allergic eye disease.

Adults and adolescents: 1 drop 2 to 3 times daily upto 14 days.

Children (Older than 2 years of age): No specific studies are available in this patient group. For possible systemic effects, the dosage should exceed to 1 to 2 drops per day.

Sympathomimetic agents may cause a hypertensive crisis if used during treatment with MAOIs. Concomitant use with MAOIs is therefore contraindicated. Sedating anti-histamines can enhance the sedating effects of CNS depressant including alcohol, hypnotics, opioid analgesics, anxiolytic sedatives and anti-psycotics. They also have an additive anti-muscarinic action with other anti muscarinic drugs, such as atropine and antidepressant
