PURPOSE To evaluate the efficacy and safety of fixed-combination brimonidine tartrate 0.2%/timolol 0.5% ophthalmic solution dosed BID and demonstrate non-inferiority to concomitant use of brimonidine tartrate 0.2% BID and timolol 0.5% BID in glaucoma and ocular hypertension patients with intraocular pressure (IOP) uncontrolled on monotherapy. METHODS Randomized, multicenter, double-masked, pa...

We studied 67 patients (100 eyes) with childhood glaucoma who were treated with timolol maleate. Thirty of these patients (40 eyes) did not require additional surgery or medications after being treated with timolol (follow-up, from six to 60 months). Thirty-one eyes (78%) in this group had a pressure drop; 18 eyes (45%) had a pressure drop of greater than 10 mm Hg. We conclude that timolol is e...

Fifty-one patients with raised intraocular pressure (IOP) were treated for up to four years with one of three ophthalmic solutions: 0.5% levobunolol, 1% levobunolol, or 0.5% timolol. The study was conducted as a double-masked, randomised trial in which medications were administered twice daily to both eyes. Levobunolol and timolol were equally effective in reducing overall mean IOP; reductions ...

This study analyzed the luminance and color emmetropization response in chicks treated with the nonselective parasympathetic antagonist atropine and the sympathetic β-receptor blocker timolol. Chicks were binocularly exposed (8h/day) for 4days to one of three illumination conditions: 2Hz sinusoidal luminance flicker, 2Hz sinusoidal blue/yellow color flicker, or steady light (mean 680lux). Atrop...

In a 15-week double-blind, placebo-controlled, crossover study both carteolol 2% and timolol 0.5% produced a significant reduction in intraocular pressure. Twelve hours after administration the reduction in pressure on carteolol was significantly less than that obtained on timolol.

OBJECTIVE To compare the effectiveness and associated costs of travoprost versus a fixed combination of dorzolamide + timolol as first-line therapy for glaucoma according to data collected by the United Kingdom General Practitioner Research Database (UK-GPRD). METHODS Patients with a diagnosis of ocular hypertension, glaucoma, or who had been treated topically by surgery or laser therapy were...

AIMS To evaluate the ocular hypotensive effects and tolerability of the once daily fixed combination latanoprost-timolol versus twice daily 0.50% timolol associated or not with once daily latanoprost in patients suffering from Primary Open-Angle Glaucoma (POAG). METHODS We compared the effects of such a combination with those of 0.50% timolol alone twice daily in a group of 24 patients and wi...

The effect of topical timolol maleate 0.5% on the retinal circulation was investigated in 14 normal subjects using laser Doppler velocimetry and monochromatic fundus photography. In a double masked, randomized design, one eye received two drops of timolol maleate 0.5% and the fellow eye received two drops of placebo. Vessel diameter, maximum velocity of red blood cells, and volumetric blood flo...

Transdermal iontophoresis would be a promising method for the systemic delivery of water soluble and ionic drugs of relatively high molecular size, including peptides. The objective of the present study was to investigate the effect of biological variable such as guinea pig and human cadaver skin and other variables like drug concentration, current density on the transdermal iontophoretic trans...

BACKGROUND To evaluate the efficacy and safety of latanoprost compared with timolol in the treatment of Asian patients with chronic angle-closure glaucoma (CACG). METHODS Relevant trials were identified through systematic searches of Medline, EMBASE, PubMed, Cochrane Library, Google Scholar and several Chinese databases. The main outcome measures included absolute and relative reduction of in...
