Zoneph Eye Drop is a multi-ingredient ophthalmic solution formulated to provide symptomatic relief from ocular irritation and allergic conjunctivitis. It contains Naphazoline (0.1% w/v), a selective alpha-adrenergic agonist that acts as a vasoconstrictor to reduce redness and swelling by constricting conjunctival blood vessels. Chlorpheniramine Maleate (0.01% w/v), an antihistamine, alleviates itching and allergic responses by blocking histamine H1 receptors. Boric Acid (1.25% w/v) serves as a mild antiseptic and buffering agent, maintaining the solution’s pH and providing antimicrobial properties. Sodium Chloride (0.05% w/v) contributes to isotonicity, ensuring ocular comfort upon instillation. Hydroxypropylmethylcellulose (0.25%) acts as a lubricant, enhancing tear film stability and providing symptomatic relief from dryness and irritation. Zoneph Eye Drop is indicated for temporary relief of redness, itching, and discomfort associated with allergic conjunctivitis and minor eye irritations. It is intended for topical ophthalmic use only and should be used as directed by a healthcare professional. Patients should avoid prolonged use to prevent rebound congestion and consult a physician if symptoms persist or worsen. Proper hygiene and administration techniques are essential to minimize contamination and ensure therapeutic efficacy.
