How Does Ophthalmic Netarsudil Work?

Reviewed on 6/25/2021

What is ophthalmic netarsudil and how does it work?

Ophthalmic netarsudil is a medication used to reduce the pressure inside the eye (intraocular pressure). Netarsudil reduces aqueous humor production, and increases its outflow by blocking the activity of an enzyme known as rho kinase.

Aqueous humor is a clear fluid that fills the space between the cornea and the lens in the eye. Imbalance in the inflow and outflow of aqueous humor can affect the intraocular pressure.

How is ophthalmic netarsudil used?

Ophthalmic netarsudil is a solution topically administered in the eye to reduce intraocular pressure in eye conditions such as:

  • Open-angle glaucoma: Glaucoma is a degenerative eye disease that damages the optic nerve. Open-angle glaucoma is the most common type of glaucoma, in which the drainage angle of aqueous humor is open but the drainage channels are partially blocked.
  • Elevated intraocular pressure: Increased intraocular pressure due to imbalance in aqueous humor production and drainage.

What are the side effects of ophthalmic netarsudil?

Side effects of ophthalmic netarsudil may include:
