title: Bopindolol: a new long acting beta-receptor antagonist; its effects on haemodynamics, and on the renin response to tilting.
abstract: Oral administration of single doses of bopindolol (1-4mg) caused significant reductions in the rises of systolic blood pressure and heart rate produced by exercise; only the reduction in the rise of heart rate was significantly dose-related. Resting heart rate was reduced by bopindolol. There were small effects on resting blood pressure. Bopindolol caused a significant attenuation of the rise in plasma renin activity produced by passive head-up tilting to 75-85 degrees. Bopindolol produced a dose-related attenuation of the increase in pulse rate evoked by passive tilting. All effects 1-4 were maintained for at least 24 h. There was no measurable effect on plasma potassium concentration, peak flow rate or forced expiratory volume (FEV1).
