Effects of acetylsalicylic acid on plasma glucose, free fatty acid, betahydroxybutyrate, glucagon and C-peptide responses to salbutamol in insulin-dependent diabetic subjects.


The selective beta 2-adrenergic agonist salbutamol increases plasma glucose concentration and the rate of lipolysis when infused in pregnant diabetic women. The aim of the present study was twofold: (a) to focus on the actions of salbutamol on lipid and carbohydrate metabolism in insulin-dependent diabetics: and (b) to investigate possible interferences of acetylsalicylic acid (ASA) with the metabolic responses to i.v. salbutamol. The results obtained during salbutamol infusion (5 microgram/min) in 6 insulin-dependent diabetic subjects demonstrated that this drug caused sustained increases in plasma glucose, free fatty acid and beta-hydroxybutyrate concentrations, as well as a small and transient rise of plasma glucagon. No change in plasma C-peptide concentration occurred during salbutamol. A concurrent infusion of lysine acetylsalicylate reduced the increase in free fatty acids by half, blunted the weak glucagon response but enhanced the rise in plasma glucose following salbutamol administration. The present data show that salbutamol exerts a potent hyperglycemic, lipolytic and ketogenic effect in insulin-dependent diabetics. We suggest that this beta-adrenergic agent should be used cautiously in human diabetes mellitus.
