Abstract

Introduction

This small pilot study is the first direct comparison of the currently marketed formulations of bromfenac (0.07% solution) and nepafenac (0.3% suspension) using identical dosing regimens and including an extra pre-surgical “pulse” dose in patients undergoing cataract surgery.

Methods

Adults scheduled for unilateral phacoemulsification with intraocular lens implantation were randomly assigned to bromfenac 0.07% or nepafenac 0.3%, each given once-daily 1 day prior to surgery, on the day of surgery plus an extra dose 1 h before surgery, and for 14 days after surgery. Assessments included summed ocular inflammation score (SOIS), visual acuity (VA), and retinal thickness measured via optical coherence tomography.

Results

The study population included 49 patients (bromfenac, n = 24; nepafenac, n = 25). The percentage of patients with a SOIS = 0 (no cells or flare) at post-surgical day 15 (primary efficacy endpoint) was statistically similar between the bromfenac (57.1%) and nepafenac (50.0%) treatment groups (intent-to-treat with last observation carried forward) (P = 0.6318). The proportions of patients with an SOIS of 0 at days 3 and 8 were significantly (P < 0.05) higher in the bromfenac group (23.8 and 52.4%, respectively) versus the nepafenac group (0.0 and 20.8%, respectively). Visual acuity was similar between groups at each study visit, as were mean retinal thickness and change from baseline in retinal thickness. Rescue medication (typically difluprednate) was given on or before day 15 to 13 patients in each treatment group (bromfenac, 54.2%; nepafenac, 52.0%). There were no adverse events considered to be related to either treatment.

Conclusions

The results of this small pilot study suggest that once-daily bromfenac 0.07% produces similar benefits with regard to postsurgical inflammation, VA, and retinal thickness as once-daily nepafenac 0.3%, and possibly has a faster onset of anti-inflammatory action, when compared using identical dosing regimens.
