Ocurest AH Eye Drop is a multi-ingredient ophthalmic formulation designed to provide symptomatic relief from ocular redness, irritation, and allergic conjunctivitis. It contains Phenylephrine (0.12% w/v), a selective alpha-1 adrenergic receptor agonist that acts as a vasoconstrictor to reduce conjunctival congestion and redness. Naphazoline (0.05% w/v), another vasoconstrictor, complements this effect by constricting dilated blood vessels, thereby alleviating ocular redness and swelling. Chlorpheniramine Maleate (0.1% w/v) is an antihistamine that inhibits histamine-mediated allergic responses, effectively reducing itching, watering, and inflammation associated with allergic conjunctivitis. Menthol (0.005% w/v) provides a mild cooling sensation, enhancing patient comfort and soothing ocular irritation. Ocurest AH Eye Drop is indicated for temporary relief of eye redness, itching, and discomfort caused by allergies, environmental irritants, or minor eye injuries. It should be used as directed by a healthcare professional, with caution advised in patients with narrow-angle glaucoma, hypertension, or cardiovascular disorders due to the vasoconstrictive properties of Phenylephrine and Naphazoline. Avoid prolonged use to prevent rebound hyperemia or tolerance. This combination therapy offers rapid symptomatic relief, improving patient comfort and ocular health.
