RESUMO
PURPOSE: To investigate the treatment persistence of carteolol hydrochloride/latanoprost fixed-combination ophthalmic solution (CAR/LAT) and other ß-blocker/prostanoid FP receptor agonist fixed-combination ophthalmic solutions (BB/FP) in the treatment of glaucoma. STUDY DESIGN: Retrospective observational cohort study. METHODS: A retrospective observational cohort study using JMDC Claims Database. Patients aged 20 years or older diagnosed with glaucoma between February 1, 2017, and March 31, 2020, and prescribed CAR/LAT or another BB/FP were included. RESULTS: A total of 16,612 patients (7423 in the CAR/LAT group and 9189 in the other BB/FP group) were included. The cumulative treatment persistence rate at the end of follow-up was 42.0% (64.9% at 1 year, 53.4% at 2 years, 45.0% at 3 years, and 42.0% at 4 years) in the CAR/LAT group and 34.7% (54.8% at 1 year, 43.6% at 2 years, 37.1% at 3 years, and 34.7% at 4 years) in the other BB/FP group. Treatment persistence was significantly longer in the CAR/LAT group compared to that in the other BB/FP group (hazard ratio 0.747, p < 0.0001). Over the treatment period, the number of patients who discontinued treatment was 3281 (44.2%) in the CAR/LAT group and 4926 (53.6%) in the other BB/FP group; the median duration of treatment was 135 days and 97 days, respectively. CONCLUSION: The study results suggest that persistence rates vary depending on the BB/FP and CAR/LAT appears to be more persistent than other BB/FP.
