Effect of indomethacin upon the renin--angiotensin system in patients with Bartter's syndrome. 1980

H Vierhapper, and W Waldhäusl

This study reports on the influence of indomethacin upon the renin--angiotensin system in three patients with Bartter's syndrome. An analogue of angiotensin II with weak agonistic properties (succinamyl1-val5-phenylglycine-acetate8-angiotensin II) induced a fall of blood pressure and a rise of plasma renin concentration but no change in plasma aldosterone. Pretreatment with indomethacin (75 mg/day) reversed the hypotensive effect of the analogue of angiotensin II and abolished the increase of plasma renin concentration. It is concluded that elevated levels of endogenous angiotensin II are of major importance for the maintenance of blood pressure in patients with Bartter's syndrome. The inhibition of the synthesis of prostaglandins reversed some, though not all, of the metabolic abnormalities in this syndrome.

UI	MeSH Term	Description	Entries
D007213	Indomethacin	A non-steroidal anti-inflammatory agent (NSAID) that inhibits CYCLOOXYGENASE, which is necessary for the formation of PROSTAGLANDINS and other AUTACOIDS. It also inhibits the motility of POLYMORPHONUCLEAR LEUKOCYTES.	Amuno,Indocid,Indocin,Indomet 140,Indometacin,Indomethacin Hydrochloride,Metindol,Osmosin

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D011453	Prostaglandins	A group of compounds derived from unsaturated 20-carbon fatty acids, primarily arachidonic acid, via the cyclooxygenase pathway. They are extremely potent mediators of a diverse group of physiological processes.	Prostaglandin,Prostanoid,Prostanoids
D012083	Renin	A highly specific (Leu-Leu) endopeptidase that generates ANGIOTENSIN I from its precursor ANGIOTENSINOGEN, leading to a cascade of reactions which elevate BLOOD PRESSURE and increase sodium retention by the kidney in the RENIN-ANGIOTENSIN SYSTEM. The enzyme was formerly listed as EC 3.4.99.19.
