PURPOSE: The purpose of this study was to compare travoprost (TRAV; travoprost 0.004%) and the fixed-combination of dorzolamide/timolol (DTFC; dorzolamide 2.0%/timolol maleate 0.5%) ophthalmic solutions for reducing intraocular pressure (IQP) in patients with primary open-angle glaucoma (OAG) or ocular hypertension (OHT). METHODS: This was a randomized single masked, study with parallel controls. The TRAV group (n = 29) dosed once dally at 9:00 PM while the DTFC group (n = 27) dosed twice daily at 9:00 AM and 9:00 PM. IOP was measured at baseline, and following 3 weeks and 6 weeks of treatment at 8:00 AM, 12:00 PM, 4:00 PM, and 8:00 PM. RESULTS: Mean average IOP reductions from baseline during the course of the day were 7.5 (32.7%) and 7.1 (30.7%) mmHg for TRAV and 4.8 (23.1%) and 4.5 (21.7%) mmHg for DTFC at 3 weeks and 6 weeks, respectively. The greater IOP reduction for patients receiving TRAV was statistically significant at both the 3 and 6 week visite when averaged across all four time points (p < 0.01). The two products were well-tolerated over the course of the 6 week study. Some factors such as taste perversion were reported more often in the DTFC group. CONCLUSIONS: Travoprost monotherapy provided better efficacy in terms of IOP reduction and percentage of IOP reduction compared to dorzolamide 2.0%/timolol maleate 0.5% fixed combination.
