Filter by:The purpose of this study was to describe the ocular discomfort immediately upon instillation of Brinzolamide 1%/Brimonidine 0.2% Tartrate Ophthalmic Suspension, Brinzolamide 1% Ophthalmic Suspension, and Brimonidine Tartrate 0.2% Ophthalmic Solution in subjects with open-angle glaucoma and/or ocular hypertension.
The purpose of this study was to assess the efficacy and tolerability of changing to AZARGA® from prior brimonidine 0.2%/timolol 0.5% fixed combination (COMBIGAN®) therapy in patients with open-angle glaucoma or ocular hypertension and uncontrolled intraocular pressure (IOP).
This is a study of the safety, tolerability, pharmacokinetics (measurement of drug levels in the blood), and intraocular pressure lowering effects of OPA-6566 ophthalmic solution in subjects with primary open-angle glaucoma or ocular hypertension.
The primary objective of this study was to compare the change in intraocular pressure (IOP) of three different doses of latanoprost (75, 100 and 125 ug/ml) to that of the marketed 50 ug/ml dose, in a dose ranging study.
The objective of this study is to investigate corneal confocal microscopic findings, ocular signs and symptoms in patients on treatment with the preserved prostaglandin analogue latanoprost 0.005% eye drops (Xalatan®) and after the switch to preservative-free prostaglandin analog tafluprost 0.0015% eye drops (Taflotan®). Patients who have been using latanoprost as their prior medication (at least 6 months) and who fulfil all the inclusion criteria including the specified ocular symptoms and signs, will switch from latanoprost 0.005% eye drops to the assigned preservative-free tafluprost 0.0015% eye drops for twelve (12) months.
Intraocular pressure (IOP) is considered to be the main risk factor for progression of glaucoma and therefore the main target of therapy. Pharmacologic treatment of glaucoma has changed considerably during the last decades due to the introduction of prostaglandin analogues. Three of these are commonly used in North America: latanoprost (Latanoprost T, Pfizer), Travoprost (Travatan TM, Alcon) and bimatoprost (Lumigan TM, Allergan). There have been several studies to evaluate their effectiveness. The three seem to be equivalent, according to the only study that has compared the molecules. Latanoprost is employed initially, due to its paucity of side effects when compared to the other two analogues. However, if it is not effective, several studies ahve shown that a result is possible using either travoprost or bimatoprost. No study has been conducted to date systematically comparing the three molecules in cases of resistance to latanoprost. In actuality, the investigators patients will receive treatment identical to current practice with the exception of the group continuing with latanoprost. Several studies confirm the benefit of changing prostaglandin analogues if the first has not signficantly decreased the IOP (Palmberg et al. 2004). Each prostaglandin has unique properties which may cause the mechanism of action to vary slightly among patients. (cf. Pharmacological Aspects) The goal of the study is thus to evaluate the efficaciousness of latanoprost, bimatoprost and travoprost in their IOP-lowering capacity in patients who do not initially respond to latanoprost.
The purpose of this study was to compare the intraocular pressure (IOP)-lowering efficacy and safety of AZARGA™ (Brinzolamide 1%/Timolol 0.5% Ophthalmic Suspension), dosed twice daily versus AZOPT® (Brinzolamide 1% Ophthalmic Suspension) and Timolol 0.5% Ophthalmic Solution, each dosed twice daily, in Chinese patients with open-angle glaucoma or ocular hypertension who were insufficiently responsive to monotherapy.
Safety and IOP (intraocular pressure) lowering effect of DE-111 ophthalmic solution will be evaluated in open-angle glaucoma or ocular hypertension patients, in an open-label, multicenter study.
This single-center, investigator-masked, crossover study is designed to investigate the circadian rhythms of aqueous humor dynamics in human subjects with ocular hypertension (OHT) before and after intervention with a commonly used ocular hypotensive medication, brimonidine.
DE-111 ophthalmic solution will be evaluated for superiority in comparison with Timolol ophthalmic solution 0.5%, in IOP(intraocular pressure ) -lowering effect in primary open-angle glaucoma or ocular hypertension patients, in a multicenter, randomized, double-masked, parallel-group comparison study. Safety will be compared and evaluated as well.
