Efficacy of preserved Tafluprost 0.0015% in lowering intraocular pressure

Abstract

Objective: To investigate the intraocular pressure (IOP) lowering effect of topical preserved tafluprost 0.0015% in a tertiary hospital setting in India. Methods: This is a retrospective chart review of patients with primary open-angle glaucoma (POAG) or ocular hypertension (OHT) attending regular outpatient visits in December 2019 and January 2021, and treated with topical preserved tafluprost 0.0015%. Based on their medication history, patients were divided into two groups, the “treatment naïve” group and the “switched” group, which included patients switched to tafluprost monotherapy after treatment with at least one prior drug. Results: The mean IOP of the study population reduced significantly from baseline level by 20.6% and 25.5% at 1 month and 3 months after preserved tafluprost 0.0015% treatment (P < 0.001 for both). The mean IOP in patients with only OHT reduced significantly from baseline level by 21% and 26% at 1 month and 3 months after preserved tafluprost 0.0015% treatment (P < 0.001 for both). The mean IOP in patients with POAG reduced significantly from baseline level by 19% and 24% at 1 month and 3 months after preserved tafluprost 0.0015% treatment (P < 0.001 for both). The baseline IOP ± SD in POAG treatment naïve patients was 25.3 ± 0.3 mmHg, which reduced significantly by 24% and 28% at 1 month and 3 months after preserved tafluprost 0.0015% treatment (P < 0.001 for both). The baseline IOP ± SD in POAG switched patients was 24.3 ± 0.1 mmHg, which reduced significantly by 18% and 22% at 1 month and 3 months after preserved tafluprost 0.0015% treatment (P < 0.001 for both). In the POAG switch group, the percent reduction in IOP at 3 months after preserved tafluprost 0.0015% treatment was 23% with timolol as first line, 22% with bimatoprost as first line, 20% with latanoprost as first line, and 19% with travoprost as first line (P < 0.001 for all). Conclusions: We show significant IOP reduction with preserved tafluprost 0.0015% in a real-world setting. As first-line monotherapy in patients with OHT and in POAG–naïve patients, preserved tafluprost 0.0015% significantly reduced IOP at 3 months. Even as second-line therapy in nonresponders (POAG-Switched) to various drugs (same class [PGAs] versus different class), treatment with preserved tafluprost 0.0015% resulted in significant IOP reduction at 3 months.
