Trial Summary

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are using topical NSAIDs or steroids.

What data supports the effectiveness of the drug Loteprednol Etabonate Ophthalmic Gel [Lotemax] for reducing post-injection pain in age-related macular degeneration?

Loteprednol Etabonate Ophthalmic Gel has been shown to effectively reduce inflammation and pain after eye surgeries, such as cataract surgery, by improving drug delivery and penetration into eye tissues. This suggests it may also help with pain after eye injections, like those used in age-related macular degeneration.12345

Is Loteprednol safe for treating post-injection pain in age-related macular degeneration?

Loteprednol etabonate, used in eye gel form, has been shown to be safe and well-tolerated for treating inflammation and pain after eye surgery, with a low risk of increasing eye pressure. In clinical trials, side effects were rare and included mild issues like eye discomfort or swelling. This suggests it is generally safe for use in humans.12456

How does the drug loteprednol differ from other treatments for post-injection pain in age-related macular degeneration?

Loteprednol is a corticosteroid that is used in a gel form with submicron particle size, which improves its delivery and penetration into eye tissues, requiring less of the drug to be effective. This formulation is unique compared to other treatments as it is specifically designed to reduce inflammation and pain with minimal impact on eye pressure and vision.12357

What is the purpose of this trial?

Patients are already receiving an intravitreal injection as a standard of care, but they are consenting to receiving a loteprednol drop following the intravitreal injection. This clinical trial is studying the role of loteprednol (corticosteroid) in reducing pain following intravitreal injections for patients with age-related macular degeneration. As of now, there is no definitive pain management technique following intravitreal injections. Loteprednol is a corticosteroid widely used in ophthalmology to treat pain and inflammation, however, it has not been studied as a treatment for pain following intravitreal injections. Our overall goal is to manage pain to improve quality of care after intravitreal injections. Participants will be given either loteprednol, or artificial tears following one visit for an intravitreal injection to test how effective loteprednol is in pain reduction. Pain levels will be assessed by asking participants over the phone about their pain from a scale of 0 to 10 at three different times over a 1-week period. Artificial tear and medication usage will also be tracked over a 1-week period.

Treatment Details

Interventions

  • Loteprednol Etabonate Ophthalmic Gel [Lotemax]
  • Nepafenac Ophthalmic 0.3% Ophthalmic Suspension
  • Refresh Lubricant Eye Drops [Artificial Tears]
Trial Overview The trial tests if loteprednol (a corticosteroid) drops can reduce pain after intravitreal injections compared to artificial tears. Participants will receive one of the treatments and report their pain levels over a week via phone calls.

Findings from Research

Loteprednol etabonate ophthalmic gel 0.38% is effective in significantly reducing ocular inflammation and pain after cataract surgery, with complete resolution observed in more patients compared to a placebo by day 8, and pain relief noted as early as day 3.
The gel formulation has a lower incidence of treatment-related ocular adverse events (less than 1%) and does not significantly affect intraocular pressure or visual acuity, making it a safe option for post-operative care.
Loteprednol Etabonate (Submicron) Ophthalmic Gel 0.38%: A Review in Post-Operative Inflammation and Pain Following Ocular Surgery.Kang, C., Keam, SJ., Shirley, M., et al.[2021]
In a study involving 406 patients after cataract surgery, the new gel formulation of loteprednol etabonate 0.5% significantly improved the resolution of inflammation and pain compared to a placebo, with 30.5% of patients achieving complete resolution of inflammation and 72.9% reporting no pain by day 8.
The treatment was found to be safe, with only one patient in each group experiencing a significant increase in intraocular pressure, and over 85% of patients reported no discomfort during drop instillation.

In a study of 59 patients undergoing intravitreal Ozurdex injection, the use of topical 0.1% nepafenac significantly reduced pain compared to a placebo, with a median pain score of 2 versus 4 (p < 0.001).
The findings suggest that topical 0.1% nepafenac provides an additive analgesic effect when used alongside standard topical anesthesia, enhancing patient comfort during the procedure.
