Previously, we reported that intranasal (IN) ACTH(1-24) administration stimulates adrenocortical steroid secretion in normal subjects. To determine the efficiency of transmucosal absorption of ACTH into the adrenal medulla, we measured serum cortisol, aldosterone, epinephrine, norepinephrine and dopamine levels after IN vs. intravenous (IV) administration of 250 microg ACTH(1-24) in 7 healthy adult men (mean age 21.7 +/- 1.2 yr; range, 21 - 24 yr). Blood was collected at 0, 30, 60 and 120 min after administration of ACTH(1-24), and the levels of adrenocortical steroids and catecholamines were measured by specific RIA and HPLC methods, respectively. There were no side effects associated with IN or IV ACTH administration. Consistent with the previous study, serum cortisol and aldosterone increased after IN administration of ACTH(1-24), peaking 30 min after administration. Sixty minutes after IN and IV administration of ACTH, epinephrine levels increased by 41.9 +/- 13.1 % and 63.3 +/- 11.8 %, respectively, and remained elevated throughout the sampling period. Thirty minutes after IN or IV administration of ACTH(1-24), plasma norepinephrine levels increased by 55.9 +/- 13.4 % and 73.7 +/- 15.0 %, respectively, peaking 30 min after ACTH(1-24) administration, and decreasing to basal levels within 60 min. Plasma dopamine levels did not change after IN administration of ACTH(1-24). Adrenocortical steroid and catecholamine levels did not increase after IN administration of saline. These results demonstrate that IN administration of ACTH(1-24) not only stimulates adrenocortical steroids, but also epinephrine and norepinephrine.
