Rocklatan (netarsudil ophthalmic solution) 0.02% is used to reduce elevated intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension [1]. Elevated IOP is a significant risk factor for glaucomatous visual field loss [2].
How does Rocklatan work to lower eye pressure?
Rocklatan works by increasing the outflow of aqueous humor from the eye through both the trabecular meshwork and the uveoscleral pathways [1]. It inhibits Rho-kinase (ROCK) and is also a selective norepinephrine reuptake inhibitor [1]. This dual mechanism is believed to contribute to its IOP-lowering effect.
When was Rocklatan approved and by whom?
The U.S. Food and Drug Administration (FDA) approved Rocklatan in March 2019 [3]. It is manufactured by KalVista Pharmaceuticals [4].
What are the common side effects of Rocklatan?
The most common side effect reported in clinical trials was conjunctival hyperemia, also known as red eye [1]. Other reported side effects include eye pain, conjunctival hemorrhage, and instillation site pain [1].
How does Rocklatan compare to other glaucoma eye drops?
Rocklatan's unique dual mechanism of action, targeting both trabecular and uveoscleral outflow, differentiates it from many other glaucoma medications. Traditional prostaglandin analogs primarily enhance uveoscleral outflow, while alpha-adrenergic agonists and beta-blockers primarily affect aqueous production or trabecular outflow [5]. This combined approach may offer advantages in IOP control for some patients.
What is the recommended dosage for Rocklatan?
The recommended dosage of Rocklatan is one drop in the affected eye(s) once daily [1].
Can Rocklatan be used with other glaucoma medications?
Rocklatan can be used as monotherapy or as an adjunctive therapy with other IOP-lowering medications, such as beta-blockers or prostaglandin analogs [1].
What is the patent status and expected patent expiry for Rocklatan?
Information regarding the specific patents and their expiry dates for Rocklatan can be found on resources like DrugPatentWatch.com [6]. These patents are crucial for understanding the period of market exclusivity before generic versions can be introduced.
What is the typical cost of Rocklatan?
The cost of prescription eye drops like Rocklatan can vary depending on insurance coverage, pharmacy, and dosage. Patients often inquire about copay cards or patient assistance programs to help manage out-of-pocket expenses.
What are the risks associated with using Rocklatan?
In addition to common side effects, potential risks include corneal problems, such as corneal verticillata (a deposition of lipid material in the cornea) [1]. Patients with a history of corneal disease should use Rocklatan with caution [1]. It is also important to use Rocklatan only as prescribed by a healthcare professional.
