Furosemide-d5 is intended for use as an internal standard for the quantification of furosemide by GC- or LC-MS. Furosemide is a loop diuretic and an inhibitor of the Na+/K+/2Cl- (NKCC) cotransporters, NKCC1 and NKCC2 (Kis = ~10 µM for both).1,2 In vivo, furosemide (0.1 mg/kg, p.o.) increases diuresis in beagle dogs.3 Furosemide (30 mg/kg) reduces ventricular collagen deposition and fibrosis in a rat model of dilated cardiomyopathy.4 It is also an inhibitor of carbonic anhydrase I (CAI), CAII, and CAIII (Kis = 0.052-0.065 µM) and organic ion transporter 1 (OAT1; Ki = 9.5 µM), as well as a GABAA receptor antagonist.5,6,7

Quantification of furosemide in camel plasma by high resolution mass spectrometry, application on pharmacokinetics
Biomed Chromatogr 2017 Jun;31(6).PMID:27859445DOI:10.1002/bmc.3902.
We developed and validated a high-resolution liquid chromatography mass spectrometry method for the quantification of furosemide in camel plasma which was used for a pharmacokinetic study in camels. Plasma samples were extracted by supported liquid extraction and furosemide and internal standard (Furosemide-d5) were separated on a an Agilent Zorbax XDB C18 column (50 × 2.1 mm i.d., 3.5 μm). Data was acquired in full-scan mode over a mass range of 200-400 Da in negative electrospray mode at a resolution of 70,000. Linear calibration curves were obtained over the concentration ranges of 1.0-10,000 ng/mL. The validated method was then successfully applied in evaluating the pharmacokinetics and metabolites of furosemide in six camels (Camelus dromedarus) and we were able to advice on a withdrawal time of furosemide treatment before racing.
Detection, quantification, and pharmacokinetics of furosemide and its effects on urinary specific gravity following IV administration to horses
Vet Ther 2003 Winter;4(4):350-63.PMID:15136977doi
Furosemide is a potent loop diuretic used for the prevention of exercise-induced pulmonary hemorrhage in horses. This drug may interfere with the detection of other substances by reducing urinary concentrations, so its use is strictly regulated. The regulation of furosemide in many racing jurisdictions is based on paired limits of urinary SG (<1.010) and serum furosemide concentrations (>100 ng/ml). To validate this regulatory mechanism, a liquid chromatography/mass spectrometry/mass spectrometry method employing a solid-phase extraction procedure and Furosemide-d5 as an internal standard was developed. The method was used to determine the pharmacokinetic parameters of furosemide in equine serum samples and its effects on urinary SG after IV administration (250 mg) to 10 horses. Pharmacokinetic analysis showed that serum concentrations of furosemide were well described by a two-compartmental open model. Based on results in this study, it is very unlikely for horses to have serum furosemide concentrations greater than 100 ng/ml or urine SG less than 1.010 at 4 hours after administration (250 mg IV). However, it should be remembered that urine SG is a highly variable measurement in horses, and even without furosemide administration, some horses might naturally have urine SG values less than 1.010.
