[Effect of penbutolol on the hemodynamics in patients with hypertensive disease]

It was found that a hypotensive effect of penbutolol used for treatment of 234 patients with hypertensive disease exceeded that of propranolol and developed at a dose of 20-80 mg a day at the end of the 2nd week of treatment. Penbutolol produces a less negative chronotropic effect as compared to propranolol. The excess of penbutolol therapeutic dose leads to the further augmentation of a positive clinical effect.
