چکیده

In Io patients with neurocirculatory asthenia the effect of two adrenergic beta-blocking drugs, propranolol and practolol, were studied on the ST-T changes observed in the resting electrocardiogram and on those occurring under orthostatic conditions. The drugs were administered intravenously on different occasions. Propranolol improved the ST-T abnormalities in the resting electrocardiogram in all Io patients and in 6

The Myocardial Depressant Effect of Beta-Receptor Blocking Agents COMPARATIVE STUDY OF <//-PROPRANOLOL, d-PROPRANOLOL. AND PRACTOLOL IN AWAKE DOGS WITH AND WITHOUT ACUTE MYOCARDIAL INFARCTION

d/-Propranolol, d-propranolol, and practolol were administered in increasing doses to conscious dogs before and after acute coronary artery occlusion. cM-Propranolol and practolol caused dose-dependent decreases in cardiac output, stroke volume, stroke work, and maximum rate of left ventricular pressure rise before and after coronary artery occlusion. These parameters were reduced 25-40% after ...

Assessment of relative actions of beta-adrenergic blocking drugs on heart rate and left ventricular ejection using a non-invasive method in patients with aortic Starr-Edwards prostheses.

The relative effects on heart rate and left ventricular ejection at rest and during exercise ofM & B I7,8o3a, propranolol, and practolol were studied in the same 6 patients with Starr-Edwards aortic valve replacement. Changes in left ventricular ejection were measured phonocardiographically, an increase in ejection being associated with a reduction in the time between the R wave of the electroc...

Clinical evaluation of practolol in acute arrhythmias.

Practolol was administered in 47 instances of acute arrhythmia, mainly of supraventricular origin. The drug was highly effective in 75 per cent of cases, including those with acute myo-cardial infarction. The therapeutic dose ranged from 5 to I8o mg. Despite administration of doses up to 500 mg, no serious side effects were noted. The beta-adrenergic blocking agents are gaining increasingly wid...

Clinical evaluation of practolol, a new cardioselective beta-blocking agent in angina pectoris.

In a controlled double-blind study practolol, a new cardioselective beta-blocking drug, was given to 15 patients with angina pectoris, and compared with propranolol 80 mg. q.d.s. The dose of practolol ranged from 200 to 600 mg.b.d. and was decided by initial open titration in individual patients. Though practolol did not influence the incidence of angina or glyceryl trinitrate consumption, it i...
