Abstract
Background: Travoprost and timolol are topical ocular hypotensive medications that have been used in the treatment of glaucoma. The fixed combination eye drop, Duotrav (travoprost 0.004% and timolol maleate 0.5%), has recently been introduced into the market. Objective: In this paper, the results of clinical trials and existing data on the performance of travoprost/timolol are discussed and analyzed. Methods: Appopriate studies for review were identified using PubMed. Studies selected for review compared efficacy and side-effect profile of fixed combination travoprost/timolol with travoprost and timolol used concomitantly, latanoprost and timolol used concomitantly, fixed combination latanoprost/timolol, travoprost alone and timolol alone. Results/conclusion: Fixed combination eye drops such as travoprost/timolol offer the potential benefits of increased patient adherence, reduced exposure to preservatives, and reduced cost.
