title: Acute haemodynamic effects and tissue distribution of acebutolol in normotensive and spontaneously hypertensive rats.
abstract: Acute i.v. administration of 15 mg/kg acebutolol in normotensive (WKY), Okamoto (SHR) and Okamoto stroke-prone (SHR-SP) awake rats resulted in weak effects on blood pressure and in bradycardia more marked in SHR-SP. Thirty minutes after i.v. administration, lung and renal uptake of [14C]acebutolol was reduced in SHR compared to other rats. Muscle uptake was higher in SHR and blood concentration was higher in SHR-SP. Brain levels were low and similar in all rats. Plasma protein binding was identical in all rats. These results are discussed according to the characteristics of the three strains studied.
