A randomized, double-blind study was conducted to compare the effects of betaxolol and timolol on visual fields of glaucoma patients. METHODS: Sixty-four glaucoma patients were treated with either 0.5% betaxolol or 0.25% timolol eyedrops twice daily. Some examples are betaxolol HCI 0.25% or 0.5% (Betoptic, Alcon) and timolol maleate 0.25% or 0.5% (Timoptic-XE, Merck), along with their generic versions. Beta blockers lower pressure by reducing production of aqueous in the eye’s ciliary body. • Betaxolol hydrochloride, 0.5%, and timolol maleate, 0.5%, were compared in a 26-week randomized, double-masked study involving 46 patients with primary open-angle glaucoma. The two drugs were comparable with regard to both intraocular pressure-lowering efficacy and side effects. Since betaxolol is... Betaxolol hydrochloride (0.5%) and timolol maleate (0.5%) were compared in a six-month randomized, double-blind study involving 29 patients with glaucoma. The two drugs were comparable with regard to efficacy in lowering intraocular pressure. Betaxolol effected an average reduction of 7.6 mm Hg (26% … Timolol ophthalmic side effects. Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.. Although the risk of serious side effects is low when timolol is used in the eyes, side effects can occur if the medicine is absorbed into your bloodstream. Pharmacology: Betaxolol, a cardioselective (beta-1-adrenergic) receptor blocking agent, does not have significant membrane-stabilizing (local anesthetic) activity and is devoid of intrinsic sympathomimetic action.When instilled in the eye, Betaxolol has the action of reducing elevated as well as normal intraocular pressure, whether or not accompanied by glaucoma. In each of these patients, timolol was either contraindicated or had previously led to development of pulmonary symptoms or complications. Before betaxolol, mean forced expiratory volumes in one second were 66% in the men and 80% in the women of reported normal values in age- and height-matched groups. Primary open-angle glaucoma is a condition associated with an elevated intraocular pressure (IOP) that is defined as optic nerve degeneration with a slowly progressive deterioration of the visual field that may lead to blindness. 1 More than 1 million Americans are being treated for glaucoma, and 80000 are legally blind as a result of the disease. 2 Glaucoma has its highest prevalence among A family history of confirmed glaucoma was present in 31% of those on timolol, 39% of those on betaxolol, and 52% of those on carteolol (41% of all the patients studied). The main purpose of this study was to determine whether the visual field could be protected by substituting a drug with ISA activity (carteolol) or a selective β blocker 1 Schoene, R. B. et al., Am. J. Ophthal. 97:86, 1984.. a Twice the clinical concentration.. b Inhaled at 240 minutes; measurement at 270 minutes. *Timolol statistically different from Betaxolol and placebo (p < 0.05). No evidence of cardiovascular beta-adrenergic blockade during exercise was observed with Betaxolol in a double-masked, three-way crossover study in 24 normal subjects comparing
