Efficacy and safety of a systematic switch from latanoprost to travoprost in patients with glaucoma

J Glaucoma. Oct-Nov 2007;16(7):606-9. doi: 10.1097/IJG.0b013e318050ab7a.

Abstract

Purpose: To assess the efficacy and safety of systematically switching a large number of hospital-based glaucoma patients from latanoprost to travoprost therapy.

Materials and methods: In this prospective observational study, patients on latanoprost were systematically switched to travoprost without washout and followed-up for 12 weeks. The main outcome measures were control of intraocular pressure (IOP), rate of switching back, and tolerability. IOP was measured at baseline (while on latanoprost), and at weeks 6 and 12 after switching to travoprost. Adverse effects were assessed and conjunctival hyperemia was graded using a standardized scale.

Results: Ninety-three consecutive patients (mean age 63.3 +/- 12.1 y) were enrolled. Nine patients were lost to follow-up. Four patients (4.3%) were switched back to latanoprost after 6 weeks due to travoprost intolerance. There was no significant difference between mean IOP at baseline [16.4 +/- 3.4 mm Hg, 95% confidence interval (CI) 15.6-17.2] and that at week 6 (15.9 +/- 4.2 mm Hg, 95% CI 14.9-16.8) (P=0.2) and week 12 (16.4 +/- 5.7 mm Hg, 95% CI 15.1-17.7) (P=0.99). There was no significant difference in the mean hyperemia score at week 12 compared with baseline (P=0.09). The majority of patients (86.9%) felt that both medications were comparable in terms of degree of comfort; 5 felt that travoprost caused more redness.

Conclusions: In this study, when glaucoma patients were systematically switched from latanoprost to travoprost, the efficacy and safety of the 2 medications were found to be comparable. A high switch rate (95.2%) was achieved with average hyperemia scores being comparable.
