Efficacy and safety of travoprost in patients with primary open-angle glaucoma

Abstract

To study the hypotensive efficacy and safety of Travapress (0.004% travoprost) in patients with primary open-angle glaucoma (POAG). The study included 50 patients (91 eyes) aged 45 to 74 years. The first group consisted of 23 patients (41 eyes) who received monotherapy with Travaprost. Patients of the second group (27 patients, 50 eyes) Travaprost was added to therapy with timolol 0.5% (17 patients, 32 eyes) or dorzolamide 2% (10 patients, 18 eyes). Travaprost was given for a period of 6 months. IOP was determined in 2 weeks, 1, 3 and 6 months from the beginning of treatment and daily IOP measurement was at 10.00, 12.00, 14.00 and 16.00. Subjective symptoms were evaluated in points by special scales. The study was completed by 42 patients (84%, 79 eyes). Two patients (4.7%) has stopped to use Travapress due to the side effects. Local side effects were observed in 9 patients (21.4%) with mild hyperemia being the most common and seen in 5 patients (11.9%). In the first group, the maximum IOP decrease was recorded for 3 months of the study and amounted to 7.3±1.2 mm Hg (27.5%) compared to baseline. By 6 months, IOP decreased by 6.8±1.5 mm Hg on average (25.6%). In the second group in the subgroup with timolol 0,5% IOP decreased by 4,9±1.7 mm Hg (20%) compared to baseline, in the subgroup with dorzolamid 2% - by 4,3±1,3 mm Hg (16,9%) compared to baseline. Evening use the drug was accompanied by significantly lower levels of daily IOP fluctuations compared with morning intake (3.0±1.2 and 3.8±1.7 mm Hg, respectively, p = 0,002). Travapress was established as highly efficient and safe. It can be recommended for wide use in the treatment of patients with POAG.
