the hypothesis that in hypoglycaemia adrenoceptor-blocking drugs may enhance those metabolic effects of the catecholamines that remain unblocked has been investigated in 12 volunteers . alpha-adrenoceptor blockade with urapidil increased the heart rate and the plasma noradrenaline level , and increased the beta-adrenoceptor mediated cellular uptake of potassium and phosphate , and the production of lactate .
