NETARSUDIL: 1,284 Adverse Event Reports & Safety Profile

Netarsudil is a Rho kinase inhibitor. Its chemical name is (S)-4-(3-amino-1-(isoquinolin-6-yl-amino)-1-oxopropan-2-yl) benzyl 2,4-dimethylbenzoate dimesylate. The molecular formula of the free base is C 28 H 27 N 3 O 3 and the molecular formula of the dimesylate is C 30 H 35 N 3 O 9 S 2 . The molecular weight of the free base is 453.54 and the molecular weight of the dimesylate is 645.74. The chemical structure is: Netarsudil dimesylate is a light yellow-to-white powder that is freely soluble in water, soluble in methanol, sparingly soluble in dimethyl formamide, and practically insoluble in dichloromethane and heptane. RHOPRESSA (netarsudil ophthalmic solution) 0.02% is supplied as a sterile, isotonic, buffered aqueous solution of netarsudil dimesylate with a pH of approximately 5 and an osmolality of approximately 295 mOsmol/kg. It is intended for topical application in the eye. Each mL of RHOPRESSA contains 0.2 mg of netarsudil (equivalent to 0.28 mg of netarsudil dimesylate). Benzalkonium chloride, 0.015%, is added as a preservative. The inactive ingredients are: boric acid, mannitol, sodium hydroxide to adjust pH, and water for injection. Netarsudil structural formula

AND USAGE RHOPRESSA is indicated for the reduction of elevated intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension. RHOPRESSA ® is a Rho kinase inhibitor indicated for the reduction of elevated intraocular pressure in patients with open-angle glaucoma or ocular hypertension. ( 1 )

AND ADMINISTRATION The recommended dosage is one drop in the affected eye(s) once daily in the evening. If one dose is missed, treatment should continue with the next dose in the evening. Twice a day dosing is not well tolerated and is not recommended. If RHOPRESSA is to be used concomitantly with other topical ophthalmic drug products to lower IOP, administer each drug product at least 5 minutes apart [see Patient Counseling Information ( 17 )]. One drop into the affected eye(s) once daily in the evening. ( 2 )

REACTIONS The most common adverse reaction is conjunctival hyperemia (53%). Other common adverse reactions, approximately 20% include: corneal verticillata, instillation site pain, and conjunctival hemorrhage.

6.1 Clinical Trials Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. The most common ocular adverse reaction observed in controlled clinical studies with RHOPRESSA dosed once daily was conjunctival hyperemia which was reported in 53% of patients. Six percent of patients discontinued therapy due to conjunctival hyperemia. Other common (approximately 20%) ocular adverse reactions reported were: corneal verticillata, instillation site pain, and conjunctival hemorrhage. Instillation site erythema, corneal staining, blurred vision, increased lacrimation, erythema of eyelid, and reduced visual acuity were reported in 5-10% of patients.

Corneal Verticillata

Corneal verticillata occurred in approximately 20% of the patients in controlled clinical studies. The corneal verticillata seen in RHOPRESSA-treated patients were first noted at 4 weeks of daily dosing. This reaction did not result in any apparent visual functional changes in patients. Most corneal verticillata resolved upon discontinuation of treatment.

6.2 Postmarketing Experience The following adverse reactions have been identified during postmarketing use of RHOPRESSA. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Eye disorders : Epithelial corneal edema has been reported in some patients with pre-existing corneal stromal edema or following ocular procedures (that could affect corneal endothelial function) <span class="opacity-50 text-xs">[see Warnings and Precautions ( 5.1 )]</span> .

AND PRECAUTIONS

5.1 Epithelial Corneal Edema Epithelial corneal edema, described as honeycomb or bullous, has been reported in some patients with pre-existing corneal stromal edema or following ocular procedures that could affect corneal endothelial function. Epithelial corneal edema typically resolves upon discontinuation of RHOPRESSA. Advise patients to notify their physician if they experience eye pain or decreased vision while using RHOPRESSA <span class="opacity-50 text-xs">[see Adverse Reactions ( 6.2 ) and Patient Counselling Information ( 17 )]</span> .

5.2 Bacterial Keratitis There have been reports of bacterial keratitis associated with the use of multiple-dose containers of topical ophthalmic products. These containers had been inadvertently contaminated by patients who, in most cases, had a concurrent corneal disease or a disruption of the ocular epithelial surface <span class="opacity-50 text-xs">[see Patient Counseling Information ( 17 )]</span>.

5.3 Use with Contact Lenses Contact lenses should be removed prior to instillation of RHOPRESSA and may be reinserted 15 minutes following its administration.
