Decrease of peripheral resistance after acute intravenous application of a new beta-receptor blocking agents, bufuralol HCl.
The hemodynamic effects of a new beta-receptor blocking agent, bufuraolo HCl, were compared with those of pindolol. Contrary to pindolol, bufuralol HCl induces a decrease of the peripheral resistance immediately. Under exercise conditions, the peripheral resistance increases under pindolol whereas it remains constant under bufuralol HCl in spite of reduced cardiac output. As an explanation, an effect of bufuralol HCl on peripheral resistance is discussed which might be independent of the beta-receptor blocking effects in the periphery.
