The effect of treatment of hypertension with nifedipine on plasma renin activity, blood serum level of aldosterone in the course of renin test, and cortisol and growth hormone concentrations after stimulation with insulin hypoglycemia was followed during two weeks of treatment in 40 patients with essential hypertension. No significant differences in the secretion of the hormones studied, as compared to the patients with the normal arterial blood pressure, were found. After nifedipine treatment no significant changes in the secretion of aldosterone, cortisol and growth hormone were observed despite a significant fall in the arterial blood pressure while there was a moderate stimulatory effect on renin secretion. The results obtained indicate that nifedipine has only small effect on the hormonal system of patients with essential hypertension.
