Efficacy and safety of travoprost 0.004% compared with tafluprost 0.0015% in patients with primary open-angle glaucoma

Background: This prospective, open, randomized, parallel-group, comparative study is to evaluate the efficacy and side-effect profile of travoprost (TRAV) 0.004% compared with tafluprost (TAF) 0.0015% in patients with primary open-angle glaucoma (POAG) over 12 weeks. A total of 80 patients of POAG selected and were randomized to either TRAV or TAF monotherapy administered once daily in the evening for 12 weeks.Methods: The study was conducted on 80 cases of POAG, in which patients were randomized to either TRAV or TAF monotherapy administered as 1 drop daily in the evening for 12 weeks. Intraocular pressure (IOP) was measured (8 am, 12 noon and 4 pm) at each visit, slit-lamp bio-microscopy was done and side effects noted.Results: The mean IOP reduction in TRAV group decreased from 27.58±2.30 to 19.03±2.326 thus resulting in fall of 8.55 (31.0%) and in TAF group it decreased from 27.38±2.676 to 20.58±2.827 resulting in fall of 6.8 mm Hg (24.8%) was significant (p<0.05). In both treatment groups, the most frequently reported adverse event at 12 weeks was red eye, noted in, 9 (22.5%) and 7 (17.5%) cases of TRAV and TAF groups respectively, though the difference was not statistically significant.Conclusion: TRAV 0.004% monotherapy produced lower diurnal IOP than TAF 0.0015% in patients with POAG and exhibited a similar safety profile
