The Efficacy and Safety Associated with Switching from Concomitant Brimonidine and Ripasudil, or Brimonidine or Ripasudil Monotherapy to a Fixed Combination of Brimonidine and Ripasudil in Glaucoma Patients
Objectives: The purpose of this study was to investigate switching from brimonidine and ripasudil, and brimonidine or ripasudil, to a fixed combination of brimonidine and ripasudil, and evaluate the associated efficacy and safety in glaucoma patients. Methods: Glaucoma patients undergoing treatment with at least brimonidine and ripasudil (n = 25) or treatment with at least brimonidine or ripasudil (n = 45) were evaluated in this retrospective study. After switching patients taking brimonidine and ripasudil, or brimonidine or ripasudil, to a ripasudil/brimonidine fixed-combination, ophthalmic suspension (RBFC), intra-ocular pressure (IOP), conjunctival hyperemia and superficial punctate keratopathy (SPK) were evaluated before and at 4, 12 and 24 weeks after switching to RBFC. Results: No significant differences in the IOPs were observed after switching from brimonidine and ripasudil to RBFC. However, a significant decrease was observed at 4, 12 and 24 weeks in the baseline IOP, from 17.0 ± 4.4 mmHg to 15.7 ± 3.2 mmHg (p < 0.01), 14.3 ± 3.4 mmHg (p < 0.01) and 14.4 ± 4.1 mmHg (p < 0.01), respectively, after switching from brimonidine or ripasudil to RBFC. No significant changes were noted for the SPK score or conjunctival hyperemia score at any of the visits after switching to RBFC. Conclusions: Throughout the 24-week evaluation period, the IOP was maintained after switching from brimonidine and ripasudil to RBFC. However, there was a significant decrease in the IOP after switching from brimonidine or ripasudil to RBFC. These results demonstrate that RBFC is safe for use in the treatment of glaucoma patients.
