Furosemide (Lasix), a widely used diuretic, is metabolized by the fungus Cunninghamella elegans (ATCC 36112) to 4-chloro-5-sulfamoyl anthranilic acid (CSA), a metabolite also present in mammalian systems. This metabolite was isolated following preparative-scale incubations of C. elegans, and was characterized

Urine from 5 renal transplant recipients treated with frusemide was analyzed for unchanged frusemide (F), glucuronidated frusemide (G) and 4-chloro-5-sulfamoylanthranilic acid (CSA) by HPLC. In 3 recipients, whose renal function recovered steadily and whose hepatic function was normal throughout, the

The objectives of this study were to qualitatively and quantitatively compare the metabolism, pharmacokinetics, and bioavailability of furosemide in healthy volunteers after intravenous and oral administration. We also determined the plasma protein binding of furosemide in vivo after iv administration.
