Effect of inhibitors of prostaglandin synthesis on induced diuresis in cirrhosis. 1983

D Mirouze, and R D Zipser, and T B Reynolds

The effect of inhibitors of prostaglandin synthesis on diuretic action was examined in patients with ascites due to chronic liver disease and in normal subjects. In patients with ascites, natriuresis after 80 mg i.v. furosemide was reduced 82% by pretreatment with indomethacin. Creatinine clearance was reduced only 16%. These effects were likely due to inhibition of renal prostaglandin synthesis, since urinary prostaglandin E2 fell and there was also reduction in natriuresis with naproxen (52%). The effects were not specific for furosemide since spironolactone-induced natriuresis was also reduced by indomethacin (82%), naproxen (52%), and aspirin (33%). In normal subjects, indomethacin reduced furosemide natriuresis by only 14% while creatinine clearance was not affected. The mechanisms of these drug interactions are uncertain but probably involve renal hemodynamics which appear to be supported importantly by renal prostaglandins in patients with ascites due to liver disease.

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

D009318	Natriuresis	Sodium excretion by URINATION.	Natriureses
D011188	Potassium	An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
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
D003401	Creatine	An amino acid that occurs in vertebrate tissues and in urine. In muscle tissue, creatine generally occurs as phosphocreatine. Creatine is excreted as CREATININE in the urine.
