Four patients with idiopathic orthostatic hypotension (I.O.H.) and one with postural hypotension and diabetes were studied. Plasma-renin activity (P.R.A.) was low and did not rise appropriately with salt restriction and diuretic stimulation. Aldosterone levels were normal and rose with diuretic therapy. Plasma-volume, plasma dopamine beta-hydroxylase, urinary catecholamines, metanephrines, and vanillyl mandelic acid (V.M.A) were normal. Treatment with indomethacin (75-150 mg/day) raised the upright blood-pressure (B.P.) by an average of 20-30 mm Hg diastolic and allowed the four patients with I.O.H. to walk about without orthostatic symptoms but it had no effect in the fifth patient. When indomethacin was discontinued in one patient who had been taking it for 9 months with symptomatic relief, the B.P. fell to pretreatment levels within 48 h. When indomethacin was reinstituted the B.P. rose again. Indomethacin was more effective in these patients than either propranolol or fludrocortisone. There may be an absolute or relative excess of certain vasodepressor prostaglandins in the peripheral vessels which results in pooling of blood and orthostatic hypotension. If this is the case indomethacin might improve the orthostatic symptoms of I.O.H. by its inhibitory effect on prostaglandin synthesis, but its mechanism of action remains to be determined.
