| Sumario: | Michael J Miyashiro1, Samuel C Lo2, Jeanette A Stewart3, William C Stewart31Ludwig Ophthalmology Centre, Hilo, HI, USA; 2Private Practice, Honolulu, HI, USA; 3PRN Pharmaceutical Research Network, LLC, Dallas, TX, USAObjective: To examine the efficacy, safety, and tolerability of travoprost 0.004% benzalkonium chloride (BAK)-free compared with previous use of latanoprost 0.005% in Japanese patients living in the US who had primary open-angle glaucoma or ocular hypertension.Methods: This was an open-label, multicenter, bilateral, intraindividual, and active-controlled study in which 20 Japanese American patients with primary open-angle glaucoma or ocular hypertension who had been on latanoprost 0.005% monotherapy were changed to monotherapy with travoprost 0.004% BAK-free daily for 12 weeks. Patients were administered the same series of tests to evaluate the efficacy, safety, and tolerability of latanoprost at the baseline visit and of travoprost BAK-free at the week 12 visit.Results: No significant difference in mean intraocular pressure (IOP) was observed between latanoprost monotherapy at baseline and travoprost BAK-free monotherapy after 12 weeks (P = 0.76), nor were significant differences noted in mean ocular hyperemia, visual acuity, corneal fluorescein staining, or overall scores from the Ocular Surface Disease Index. Patients had a significantly shorter mean tear breakup time while on latanoprost compared with travoprost BAK-free (P = 0.0094). Significantly more patients preferred travoprost BAK-free monotherapy over latanoprost monotherapy (14 versus 6; P = 0.011).Conclusion: The results of this study suggest that Japanese American patients transitioned from latanoprost 0.005% monotherapy to travoprost 0.004% BAK-free can expect similar IOP control and some improvement in anterior segment signs. This transition study showed a strong patient preference for travoprost BAK-free over latanoprost, at a ratio of more than 2:1.Keywords: glaucoma, intraocular pressure, latanoprost, prostaglandin analog, travoprost |
