Information Netarsudil (AR-13324) 2HCl Netarsudil (a.k.a. AR-13324) is ROCK inhibitor with Ki value of 0.2-10.3 nM. It is currently in clinical trials for the treatment of glaucoma and ocular hypertension. Targets norepinephrine transporter (NET) ; ROCK ; 2 nM(Ki) In vivo Netarsudil primarily targets cells in the conventional outflow tract, efficiently decreasing IOP in both human and non-human primate eyes. In addition, netarsudil has been shown to increase outflow facility in non-human primate eyes and to decrease episcleral venous pressure in rabbit eyes.
