Action of β-Adrenergic Blocking Agents on the Urethral Pressure Profile

Abstract
The action of β-adrenergic blocking agents on the urethral pressure profile was studied. Sotalol, 20 mg, and inderal, 7 mg, were administered intravenously. Whereas the α-adrenergic blocking drug phentolamíne, as already known, changed the maximum value of the pressure profile with an average decrease of 33%, the β-adrenergic blocking drugs did not show any action at all. There was no difference between the results obtained with Sotalol and Inderal.
