The effects of intravenously administered aminophylline of growth hormone (GH) secretion have been studied in sixteen normal subjects and four acromegalic patients. Intravenous infusion of theophylline ethylenediamine 480 mg over a 30 min period did not alter the blood glucose and serum GH levels in six normal subjects but raised the plasma FFA by 88%. By contrast, in four acromegalic patients theophylline administration resulted in a fall of the serum GH levels by 17.6-51.7%, mean 36.5%. In ten normal subjects the infusion of the drug clearly blunted the GH response to insulin hypoglycaemia without modifying the decrease in blood glucose and plasma FFA induced by insulin: mean peak GH values decreased from 32.7±3.39 to 21.4±4.10 ng/ml (P
