Netarsudil Mesylate: Investment Scenario, Market Dynamics, and Financial Trajectory

Last updated: February 3, 2026

Summary

Netarsudil mesylate is a Rho kinase (ROCK) and norepinephrine transporter (NET) inhibitor approved for the treatment of elevated intraocular pressure (IOP) in glaucoma and ocular hypertension. Since its FDA approval in 2017 (Rocklatan®), it has established a niche within the ophthalmology therapeutic landscape. This analysis presents a comprehensive overview of its investment potential, market forces, and projected financial trajectory through 2030.
