Characterization of furosemide-induced activation of the renal prostaglandin system. 1979

G Ciabattoni, and F Pugliese, and G A Cinotti, and G Stirati, and R Ronci, and G Castrucci, and A Pierucci, and C Patrono

A detailed time course of changes in plasma renin activity (PRA), urinary prostaglandin (PG) E2, PGF2 alpha, thromboxane (TX) B2 and sodium excretion rates following furosemide was obtained in 7 women. PRA increased within the first 15 min and remained elevated all through the experiment. PGE2, PGF2 alpha, TXB2 and sodium increased simultaneously, reached a peak between 15 and 45 min after furosemide and declined thereafter. It is concluded that furosemide induces a generalized activation of the renal PG system temporally related to the increase of renin release and natriuresis.

D007668 Kidney Body organ that filters blood for the secretion of URINE and that regulates ion concentrations. Kidneys
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.
