Trandolapril in Cushing's disease: short-term trandolapril treatment in patients with Cushing's disease and essential hypertension.

A study was performed on seven patients with Cushing's disease and seven age and sex matched patients with essential hypertension. The patients maintained their usual diet and sodium intake and received the ACE inhibitor trandolapril at a dose of 2 mg daily for 8 days. Trandolapril treatment resulted in an increase in the active renin and decrease in the urinary kallikrein activity in both study groups.

Losartan in Cushing's syndrome.

Eleven patients with Cushing's syndrome were included in the study. They maintained their usual sodium intake and received a single oral dose of 50 mg of the angiotensin II antagonist receptor losartan for 3 days. Losartan treatment resulted in stimulation of active renin and decrease of plasma and urinary kallikrein activity.
