Abstract: The contribution of beta 1-adrenoceptors to the regulation of plasma renin activity was investigated in nine healthy sodium-replete volunteers: seven subjects received a cumulative intravenous dose of 75 micrograms/kg prenalterol, a predominant beta 1-adrenoceptor agonist, and two subjects only vehiculum. In the seven actively treated subjects beta 1-adrenoceptor agonism increased (P less than 0.001) systolic intra-arterial pressure by an average of 16 +/- 4 mm Hg and heart rate by 19 +/- 3 beats min. These increases were significantly (P less than 0.04) different from the changes observed in the two control subjects (+ 3 +/- 4 mm Hg and -1 +/- 4 beats/min, respectively). Plasma renin activity, however, tended to decrease in both the actively (-38%) and saline (-28%) treated subjects. Predominant beta 1-adrenoceptor agonism, powerful enough to increase systolic pressure and heart rate does not increase plasma renin activity in supine sodium-replete normal man.
