Ocular discomfort was rated 1 minute after instillation of each medication, and preference was noted on Day 2. Adverse events, if any, were solicited at each visit.Results: 127 subjects with ocular hypertension or open-angle glaucoma were included in the intent-to-treat analysis. Of the 106 subjects who expressed a drug preference, 79.2% preferred brinzolamide/timolol (p < 0.0001). Ocular discomfort scores were significantly higher with dorzolamide/timolol than brinzolamide/timolol (2.9 vs 1.4, respectively; p < 0.0001). Significantly more patients reported ocular pain and discomfort after dorzolamide/timolol instillation and transient blurred vision after brinzolamide/timolol instillation.Conclusions: Patients with ocular hypertension or open-angle glaucoma preferred the brinzolamide/timolol fixed combination over the dorzolamide/timolol fixed combination. This is likely due to the greater ocular discomfort associated with dorzolamide/timolol. The differences in preference, discomfort, and adverse events are likely attributable to formulation differences given the similarities of the active ingredients. Stronger patient preference for brinzolamide/timolol may lead to better therapeutic compliance.Keywords: brinzolamide/timolol, dorzolamide/timolol, patient preference, ocular discomfort, open-angle glaucoma or ocular hypertension Thomas K MundorfSteven H RauchmanRobert D WilliamsRicardo NotivolBrinzolamide/Timolol Preference Study GroupDove Medical PressarticleOphthalmologyRE1-994ENClinical Ophthalmology, Vol 2008, Iss Issue 3, Pp 623-628 (2008) |
