Atenolol versus propranolol. A comparison of ocular hypotensive effect of an oral dose.
نویسندگان
چکیده
In a controlled double-blind cross-over trial in 10 patients comprising six with open-angle glaucoma, three with closed-angle glaucoma, and one with ocular hypertension, a single oral dose of atenolol (50 mg) was significantly more effective than propranolol (40 mg) in reducing ocular tension.

Atenolol versus propranolol A comparison of ocular hypotensive
Both atenolol and propranolol by mouth reduce ocular tension in normal and glaucomatous eyes (Phillips, Howitt, and Rowlands, i967; Elliot, Cullen, and Phillips, 1975; Wettrell and Pandolfi, 1975). These drugs are f-adrenergic blockers but propranolol affects both P1 and 32 receptors (as well as having a 'membrane' effect), while atenolol is a more specific 31 receptor antagonist and lacks the ...
متن کاملEffects of betaxolol on cardiohemodynamics and coronary circulation in anesthetized dogs: comparison with atenolol and propranolol.
Effects of betaxolol, a cardioselective beta-adrenoceptor antagonist, on cardiohemodynamics and coronary circulation were investigated in two kinds of anesthetized open-chest dog preparations in comparison with those of atenolol and propranolol. When administered intravenously, betaxolol, atenolol and propranolol produced dose-dependent decreases in the heart rate (HR), maximum left ventricular...

The ocular hypotensive effect of single oral doses of (a) atenolol (50mg), (b) acetazolamide (500 mg), (c) atenolol (50 mg) and acetazolamide (500 mg) in combination, and (d) vehicle (inert tablets) were compared in 8 patients with glaucoma. In this single-dose, double-masked trial the combination was observed as most effective in reducing ocular tension. Both the combination and atenolol perfo...
متن کاملComparison of ocular hypotensive effects of 3 dosages of oral atenolol.
Oral atenolol (25 mg twice daily and 50 mg and 100 mg once daily) and placebo were tested as additional therapy in a double-masked, randomised, cross-over study. Twenty-four patients (16 with chronic simple glaucoma and 6 with ocular hypertension) participated who had an intraocular pressure (IOP) higher than 21 mmHg. The mean fall of intraocular pressure varied between 28% and 36% and was obse...
متن کاملOcular hypotensive effect of atenolol (Tenormin, I.C.I.). A new beta-adrenergic blocker.
Atenolol (Tenormin or I.C.I. 66082) is a new beta-adrenergic blocking drug, unique in being cardio-selective and in having no intrinsic sympathomimetic or membrane activity. In a controlled double-blind study, a single 50 mg oral dose produced a significant fall in ocular tension for about 7 hours in five patients with definite or suspected glaucoma. The average maximum fall was 35 per cent of ...
