PURPOSE To determine patient preference of and ocular discomfort with fixed combination brinzolamide/timolol compared with fixed combination dorzolamide/timolol. METHODS In a prospective, double-masked, randomized, active-controlled, crossover, multicenter study, patients received 1 drop of brinzolamide/timolol and dorzolamide/timolol in both eyes on consecutive days in random order. Ocular d...

BACKGROUND/AIMS To compare the intraocular pressure (IOP)-lowering efficacy of travoprost 0.004%/timolol 0.5% in fixed combination with the unfixed combination of latanoprost 0.005% and timolol 0.5% in open-angle glaucoma or ocular hypertension patients with IOP levels below 18 mmHg on the unfixed combination of latanoprost 0.005% and timolol 0.5%. METHODS Following a 30-day open-label run-in...

Brinzolamide 1%/timolol 0.5% is a new fixed-combination for the treatment of open-angle glaucoma or ocular hypertension. Brinzolamide/timolol has a favorable safety profile, with an incidence of ocular burning and stinging <5%. Published data show that brinzolamide 1%/timolol 0.5% and dorzolamide 2%/timolol 0.5% have similar efficacies for lowering intraocular pressure (IOP). There is some evid...

Timolol maleate (TiM), a nonselective β-adrenergic blocker, is a potent highly effective agent for management of hypertension. The drug suffers from extensive first pass effect, resulting in a reduction of oral bioavailability (F%) to 50% and a short elimination half-life of 4 h; parameters necessitating its frequent administration. The current study was therefore, designed to formulate and opt...

INTRODUCTION Combining two medications in one bottle may improve compliance by reducing the time required to administer drops and the frequency of the total number of medication bottles. OBJECTIVE To compare the efficacy of reduced intraocular pressure (IOP) and safety of fixed combination travoprost 0.004%/timolol 0.5% vs. fixed combination dorzolamide 2%/timolol 0.5% in patients with primar...

OBJECTIVE The aim of this study was to evaluate the efficacy and tolerability of latanoprost, compared with the combination of dorzolamide and timolol, in the treatment of patients with elevated intraocular pressure (IOP). METHODS Pertinent randomized, controlled trials were identified through systematic searches of the Cochrane Library, PubMed, EMBASE, Chinese Biomedicine Database, and inter...

The results of a 12-month blind randomised trial comparing the intraocular pressure lowering effect of timolol 0.25% with timolol 0.5% are presented. 27% of patients (22% of eyes) required additional antiglaucoma medication after a minimum time interval of 6 months to maintain an intraocular pressure less than 23 mmHg. The mean reduction in intraocular pressure (from pretreatment values) at 12 ...

Increasing the ocular absorption of timolol relative to its systemic absorption is important clinically because ophthalmic timolol may cause serious respiratory, cardiac, and central nervous system side effects. The authors evaluated the effects of phenylephrine coadministration and solution viscosity on the aqueous humor:plasma and iris ciliary body:plasma ratios of peak timolol concentrations...

Background: The first goal of medical therapy in glaucoma is to reduce intraocular pressure (IOP), and the fixed-combination medications are needed to achieve sufficiently low target IOP. The aim of this systematic review and meta-analysis is to evaluate IOP-lowering effect of the commonly used fixed-combination drugs containing 0.5% timolol. Methods: Pertinent publications were identified thro...
