DOSE‐RESPONSE RELATIONSHIPS FOR ADRENOCORTICOTROPHIN‐INDUCED HYPERTENSION IN MAN

Abstract
SUMMARY: 1. Adrenocorticotrophin (ACTH), given as long‐acting Synacthen depot (Ciba‐Geigy), at 1000 μg/day, in divided doses 12 hourly, is known to increase blood pressure in man.2. Fifty μg/day of short‐acting Synacthen given intravenously produced a rise in blood pressure and may be a threshold dose.3. Twelve hourly intramuscular injections of short‐acting Synacthen over the dose range 100–400 μg/day was not sufficient to raise blood pressure.
