DIFFERENTIAL BLOOD PRESSURE AND METABOLIC EFFECTS OF 9α‐FLUOROCORTISOL IN MAN

Abstract

The blood pressure and metabolic effects of 9 alpha-fluorocortisol at 0.15 mg/day and 1.5 mg/day were examined in man. At high dose, systolic pressure and body weight rose, and plasma [K+], urinary sodium excretion and renin concentration fell. At low dose similar metabolic effects were seen but blood pressure was unchanged. 9 alpha-Fluorocortisol has 'mineralocorticoid' effects in man at a dose which does not alter blood pressure. These studies do not provide evidence of a 'hypertensinogenic' class of steroid hormone action in man.
