Netasudil Eye Drop, containing 0.2mg of the active ingredient Netarsudil, is a prescribed ophthalmic solution designed for the reduction of intraocular pressure in patients with open-angle glaucoma or ocular hypertension. Its mechanism of action involves the inhibition of Rho kinase, leading to decreased aqueous humor production and subsequent reduction in intraocular pressure. The eye drop is administered once daily, typically in the evening, and should be used with caution in patients with a history of hypersensitivity to any of its components. Potential adverse effects include conjunctival hyperemia, ocular irritation, and dry eye symptoms. It is recommended to consult a healthcare professional for proper dosage, administration, and monitoring of any adverse reactions.
