Summary Cianergoline is a new dopaminergic agonist with a predominant cardiovascular action. Its effects on blood pressure, the renin-angiotensin-aldosterone axis, the sympathetic nervous system and lipid metabolism were assessed in 20 patients with benign essential hypertension. Cianergoline given in increasing doses for 4 weeks (maximum daily dose 12±2 mg (SD)) and placebo both caused a slight decrease in arterial pressure, (from 159/104 to 152/98 mm Hg and from 154/104 to 149/103 mm, respectively; difference not significant). Supine and upright plasma renin activity, plasma aldosterone, norepinephrine, epinephrine and dopamine levels, urinary catecholamine excretion rates as well as serum prolactin, low and high density cholesterol and triglyceride concentrations were not changed after cianergoline or placebo. Total serum cholesterol and triglyceride levels decreased significantly after placebo, but were unchanged after cianergoline. 3 out of 10 patients in the cianergoline group complained of nausea. The findings indicate that the new dopaminergic agonist cianergoline exerts only a mild blood pressure lowering effect in patients with essential hypertension and does not modify the release of prolactin, lipid metabolism or the basal activity or postural responsiveness of the renin-angiotensin-aldosterone axis and of the sympathetic nervous system.
