- maximum dose: 1 drop in affected eye(s) once everyday.
Rocklatan Dose in Childrens
Not indicated in children.
Pregnancy Risk Category: N (Not assigned)
- Systemic absorption is very limited after the ophthalmic application.
- To reduce potential exposure to the foetus, it is recommended that the minimum effective dose be used in conjunction with punctal obstruction.

Warnings and precautions
-
Bacterial Keratitis
- Inadvertent contamination with multiple-dose ophthalmic solution has led to bacterial keratitis.
-
Ocular effects
- The eyelid skin and iris pigmentation may be altered or increased.
- You may be able to increase the length and number of your eyelashes.
- While iris color changes may not be visible for many months or years, pigmentation of the eyes is likely to last a lifetime.
- After discontinuation of therapy, pigmentation and eyelash changes can be reversed.
- It is not yet known what long-term effects and potential injury the eye may have.
-
Ocular inflammation:
- Intraocular inflammation and exacerbation may occur.
- Patients with an history of intraocular inflammation (e.g., iritis/uveitis), should be cautious about using this product. Avoid use in patients with active intraocular swelling.
-
Herpetic keratitis
- Patients with a history or herpes simplex keratitis should be cautious.
- Reactivation is possible.
- Patients with active herpes simplex should be avoided.
-
Ocular disease:
- Avoid use in patients who are aphakic, pseudophakic, have a damaged posterior lens capsule or have risk factors for macular degeneration.
- Safety and efficacy of the product have not yet been established for patients with angle-closure, inflammation, or neovascular.
Netarsudil and latanoprost: Drug Interaction
Note: Drug Interaction Categories:
- Risk Factor C: Monitor When Using Combination
- Risk Factor D: Consider Treatment Modification
- Risk Factor X: Avoid Concomitant Use
Risk Factor C (Monitor therapy) |
|
| Bimatoprost | The concomitant use of Latanoprost and Bimatoprost may result in increased intraocular pressure. |
| Nonsteroidal Anti-Inflammatory Agents | May diminish the therapeutic effect of Prostaglandins (Ophthalmic). Nonsteroidal Anti-Inflammatory Agents may also enhance the therapeutic effects of Prostaglandins (Ophthalmic). |
| Nonsteroidal Anti-Inflammatory Agents (Ophthalmic) | May diminish the therapeutic effect of Prostaglandins (Ophthalmic). Nonsteroidal Anti-Inflammatory Agents (Ophthalmic) may enhance the therapeutic effect of Prostaglandins (Ophthalmic). |
Monitoring parameters:
- Examine IOP.
- Regularly examine patients who develop increased iris pigmentation
How to administer Rocklatan (Netarsudil and latanoprost)?
Ophthalmic:
- May be used with other eye drops to lower IOP.
- Administer the drugs at least 5 minutes apart, if more than one topical ophthalmic drug is being used.
- Prior to administration, remove contact lenses and wait 15 mins before reinserting.
- To minimize contamination of the dropper tip, avoid touching the dropper tip with fingers, eyes, eyelids, or surrounding areas.
Mechanism of action of Rocklatan (Netarsudil and latanoprost):
- Netarsudil acts as a Rho kinase inhibitor and latanoprost works as a prostaglandin F-2 analog.
- Both may decrease intraocular pressure by increasing outflow of aqueous matter, though the exact mechanism remains elusive.
Absorption:
- Limited
- Latanoprost absorbs through the cornea, and is hydrolyzed to the biologically activated acid (measurable in plasma and aqueous humor for the first four hours).
Metabolism:
- Latanoprost:
- Hydrolysis of Isopropyl Ester Prodrug in the cornea produces the biologically active chemical.
- Via fatty acids beta-oxidation, biologically activated acid is primarily metabolized in the liver.
Netarsudil:
- Metabolized by ophthalmic esterases to the active metabolite, AR-13503.
Half-life elimination:
- Latanoprost:
- 17 mins
Excretion:
- Latanoprost:
- Urine: ~88 percent (as metabolites)
