Latanoprost–netarsudil for previously treated primary open-angle glaucoma or ocular hypertension

Netarsudil, a Rho kinase (ROCK) inhibitor, targets the underlying pathophysiology of elevated IOP (intraocular pressure), increased trabecular outflow resistance, and thereby increases trabecular outflow and reduces IOP (1):

  • distinct mechanism of action of netarsudil has been demonstrated to involve increasing trabecular outflow by decreasing actomyocin-driven cellular contraction and reducing production of extracellular matrix proteins

Latanoprost, the most commonly prescribed prostaglandin analogue, has a complementary mechanism of action, lowering IOP by increasing uveoscleral outflow (1).

NICE states that (2):

  • latanoprost–netarsudil is recommended as an option for reducing intraocular pressure (IOP) in adults with primary open-angle glaucoma or ocular hypertension when a prostaglandin analogue alone has not reduced IOP enough, only if:
    • they have then tried a fixed-dose combination treatment and it has not reduced IOP enough, or
    • a fixed-dose combination treatment containing beta-blockers is unsuitable
