ObjectiveTo evaluate the intraocular pressure (IOP)-lowering effect based on the number of ingredients and survival rate due to adverse reactions of brinzolamide (1%)/brimonidine (0.1%) fixed combination (BBFC).Methods and analysisAmong 424 patients newly administered BBFC from June 2020 to May 2021, 406 were retrospectively evaluated for adverse reactions and 299 were evaluated for the IOP-lowering effect of BBFC. Among those evaluated for IOP, group A (n=86) included patients whose treatment was changed to BBFC from other two ingredients, Group B (n=90) included patients who added one ingredient by switching to BBFC, and group C (n=123) included patients who added BBFC in addition to other drugs.ResultsThe mean IOP (mm Hg) at BBFC initiation and at 3, 6 and 12 months after BBFC initiation was 14.1, 14.0, 14.3 and 13.8 in group A, 15.9, 14.4, 13.8 and 14.5 in group B and 17.2, 14.0, 14.1 and 14.9 in group C, respectively. Group A showed no significant difference in mean IOP from baseline to any time point after BBFC initiation, whereas groups B and C showed significant IOP reductions at all time points. Seventy-three (18%) patients discontinued treatment due to adverse reactions. The survival rate was 72% at 12 months after the start of BBFC when discontinuation due to adverse reactions was defined as failure.ConclusionUsing BBFC, sustained IOP or decreasing IOP were observed depending on the number of ingredients. Drop-outs due to the adverse reactions should also be given attention. |
