ABSTRACT Some metabolic effects of an acute β-adrenergic receptor blockade were studied in 34 healthy subjects. Plasma free fatty acid (FFA) and blood glucose levels were determined in all, and kinetic data of plasma FFA were obtained in several of these individuals. β-Adrenergic receptor blockade was induced by intravenous propranolol [l-isopropylamino-3-(l-naphthyloxy)-2-propanol hydrochloride] infusion (0.3 mg/kg/15 min). The influence of propranolol on fat mobilization was studied at metabolic rest and during both exogenous (adrenergic) and endogenous (mixed) stimulation of adipokinesis (intravenous infusion of 0.5 μg/kg/15 min of epinephrine and starvation >55 hr, respectively). At metabolic rest propranolol caused a slight drop in plasma FFA levels, due to a transient decrease in FFA production rate and an equally nonsignificant rise in the blood glucose concentrations. The adipokinetic effectiveness of the intravenous epinephrine infusion, on the other hand, was markedly suppressed by the prior adm...
