The efficacy and safety of two fixed combinations: timolol-dorzolamide-brimonidine versus timolol-dorzolamide. A prospective, randomized, double-masked, multi-center, 6-month clinical trial.

We compared the efficacy and safety of a new fixed combination of timolol 0.5%/odorzolamide 20%/brimonidine 0.2% in ophthalmic solution versus a fixed combination of timolol 0.5%/dorzolamide 2% in patients with open-angle glaucoma or ocular hypertension. The fixed triple combination was significantly more efficient in mean intraocular pressure reduction from baseline throughout the six-month follow-up.
