[Penbutolol and arterial hypertension].

Penbutolol has proved particularly effective and suitable for the treatment, even on a long-term basis, of recently developed hypertension, especially in its hyperkinetic forms. The drug produces minimal side effects, is well tolerated and gives an early therapeutic response. In addition penbutolol does not cause any significant alterations in the biohumoral parameters of the patients treated and is ideal for combination with dihydralazine, reserpine and dihydrochlorotiazide in the treatment of more stubborn cases, making it possible to reduce the doses of the other drugs without causing bradycardia.
