Mechanism of action

ROCK inhibitors modulate the cytoskeleton and cell contractility in ocular tissues, particularly enhancing conventional outflow facility in the eye's drainage system. By inhibiting ROCK signaling, DE-117B increases the ease with which fluid drains from the anterior chamber, thereby lowering intraocular pressure. This mechanism differs from prostaglandin analogs and beta-blockers, offering a novel approach to glaucoma management.
