What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing Nyxol alone and with low dose pilocarpine to help people with presbyopia see better up close. The medications work by helping the eye focus better on nearby objects.

Will I have to stop taking my current medications?

You will need to stop using any topical eye medications, except for certain over-the-counter products, at least 7 days before the trial and during the study. If you are taking any systemic adrenergic or cholinergic drugs, you should not change your dosage or start new ones within 7 days before the trial or during the study.

Is the combination of Nyxol Eye Drops and Low-Dose Pilocarpine Eye Drops safe for humans?

Research on pilocarpine eye drops shows they are generally safe, but users should be cautious when driving at night. Phentolamine mesylate, another component, has been studied for safety in eye conditions and is considered safe for long-term use in certain populations.12345

How is the drug Nyxol Eye Drops + Low-Dose Pilocarpine Eye Drops for Presbyopia different from other treatments?

This treatment combines Nyxol (phentolamine ophthalmic solution) and low-dose pilocarpine, which together help improve near vision by reducing pupil size and enhancing focus. Unlike other treatments, this combination leverages the unique effects of phentolamine on pupil modulation and pilocarpine's ability to constrict the pupil, offering a novel approach to managing presbyopia.12356

What data supports the effectiveness of the drug Nyxol Eye Drops + Low-Dose Pilocarpine Eye Drops for Presbyopia?

Research shows that phentolamine mesylate, a component of Nyxol, can improve near visual acuity in presbyopic patients, while pilocarpine has been shown to improve near vision in a modest proportion of early presbyopes by constricting the pupil, which helps reduce image blur.23456

Published Research Related to This Trial

In a Phase 2b trial involving 39 patients with elevated intraocular pressure (IOP), phentolamine mesylate ophthalmic solution (PMOS) did not significantly lower IOP compared to placebo, but showed a trend towards greater decreases in patients with lower baseline IOP.
PMOS significantly reduced pupil diameter by 20% and improved distance-corrected near visual acuity in many patients, indicating potential benefits for those with presbyopia and dim light vision disturbances, while being well tolerated with no significant side effects.
Phentolamine Mesylate Ophthalmic Solution Provides Lasting Pupil Modulation and Improves Near Visual Acuity in Presbyopic Glaucoma Patients in a Randomized Phase 2b Clinical Trial.Pepose, JS., Hartman, PJ., DuBiner, HB., et al.[2022]
The combination of pilocarpine and oxymetazoline ocular drops showed a significant dose-dependent improvement in uncorrected near visual acuity (UNVA) in individuals with presbyopia, particularly with pilocarpine concentrations between 1.16% and 1.32%.
The most common side effect reported was headache, and while pilocarpine was effective, oxymetazoline did not significantly enhance efficacy or reduce headache severity when added to pilocarpine.

Ophthalmic pilocarpine (1.25%) can improve near vision in early presbyopes, with 12-22% of patients achieving better visual acuity compared to a placebo, making it a potential treatment option for those with failing accommodation.
The drug is well tolerated, acts quickly within minutes, and its effects last for several hours, although it may cause reduced night vision and minor distance acuity issues due to smaller pupil size.
