Dosage Forms

Excipient information presented when available (limited, particularly for generics); consult specific product labeling.

Solution, Ophthalmic:

Rhopressa: 0.02% (2.5 mL) [contains benzalkonium chloride]

Brand Names: U.S.

  • Rhopressa

Pharmacologic Category

  • Rho Kinase Inhibitor


Although the exact mechanism of action of netarsudil, a rho kinase inhibitor, is unknown, it may reduce IOP by increasing the outflow of aqueous humor through the trabecular meshwork route.


Metabolized by esterases in the eye to active metabolite AR-13503.

Use: Labeled Indications

Elevated intraocular pressure (IOP): Reduction of elevated IOP in patients with open-angle glaucoma or ocular hypertension


There are no contraindications listed in the manufacturer's labeling

Dosing: Adult

Elevated intraocular pressure: Ophthalmic: Instill 1 drop into affected eye(s) once daily in the evening (maximum: 1 drop into affected eye(s) once daily).

Dosing: Geriatric

Refer to adult dosing.


Ophthalmic: For ophthalmic use only. May be used with other eye drops to lower intraocular pressure. If using more than 1 ophthalmic product, wait at least 5 minutes in between application of each medication. Remove contact lenses prior to administration and wait at least 15 minutes (after administration) before reinserting. Avoid touching the dropper tip with fingers, eyes, eyelids, or surrounding areas to minimize contamination of the dropper tip.


Store at 2°C to 8°C (36°F to 46°F) until opened. After opening, may store refrigerated at 2°C to 8°C (36°F to 46°F) until the manufacturer's expiration date or at ≤25°C (≤77°F) for ≤6 weeks. During shipment, may maintain at temperatures ≤40°C (≤104°F) for ≤14 days.

Drug Interactions

There are no known significant interactions.

Adverse Reactions

The following adverse drug reactions and incidences are derived from product labeling unless otherwise specified.


Local: Application site pain (20%)

Ophthalmic: Conjunctival hyperemia (53%), conjunctival hemorrhage (20%), corneal deposits (20%; verticillata)

1% to 10%:

Dermatologic: Erythema of eyelid (5% to 10%)

Local: Application site erythema (5% to 10%)

Ophthalmic: Blurred vision (5% to 10%), corneal staining (5% to 10%), decreased visual acuity (5% to 10%), increased lacrimation (5% to 10%)


Concerns related to adverse effects:

• Bacterial keratitis: Inadvertent contamination of multiple-dose ophthalmic solutions has caused bacterial keratitis.

Special populations:

• Contact lens wearers: Contains benzalkonium chloride, which may be absorbed by soft contact lenses. Remove contact lens prior to instillation; may reinsert 15 minutes following administration.

Monitoring Parameters

Intraocular pressure

Pregnancy Considerations

Adverse events were not observed in animal reproduction studies following clinically relevant systemic exposure. Systemic absorption is minimal following ophthalmic application. If ophthalmic agents are needed during pregnancy, the minimum effective dose should be used in combination with punctal occlusion to decrease potential exposure to the fetus (Samples 1988).
