“In contrast, when plasma glucose, insulin, and glucagon were clamped, beta adrenergic blockade completely prevented the suppression of glucose clearance by epinephrine and inhibited the stimulation of glucose production by epinephrine by 80% whereas alpha adrenergic blockade had no effect on either of these parameters.”
“These results indicate that in man, epinephrine increases glucose production and decreases glucose clearance by both alpha and beta adrenergic actions.”
