4.2 Drug Indication

For the treatment of edema associated with congestive heart failure, hepatic and renal disease including the nephrotic syndrome.


FDA Label


Treatment of autism spectrum disorder


5 Pharmacology and Biochemistry
5.1 Pharmacology

Bumetanide is a loop diuretic of the sulfamyl category to treat heart failure. It is often used in patients in whom high doses of furosemide are ineffective. There is however no reason not to use bumetanide as a first choice drug. The main difference between the two substances is in bioavailability. Bumetanide has more predictable pharmacokinetic properties as well as clinical effect. In patients with normal renal function, bumetanide is 40 times more effective than furosemide.


5.2 MeSH Pharmacological Classification

Sodium Potassium Chloride Symporter Inhibitors

Agents that inhibit SODIUM-POTASSIUM-CHLORIDE SYMPORTERS which are concentrated in the thick ascending limb at the junction of the LOOP OF HENLE and KIDNEY TUBULES, DISTAL. They act as DIURETICS. Excess use is associated with HYPOKALEMIA and HYPERGLYCEMIA. (See all compounds classified as Sodium Potassium Chloride Symporter Inhibitors.)


Diuretics

Agents that promote the excretion of urine through their effects on kidney function. (See all compounds classified as Diuretics.)

5.5 Absorption, Distribution and Excretion

Absorption

Bumetanide is completely absorbed (80%), and the absorption is not altered when taken with food. Bioavailability is almost complete.


Route of Elimination

Oral administration of carbon-14 labeled Bumex to human volunteers revealed that 81% of the administered radioactivity was excreted in the urine, 45% of it as unchanged drug. Biliary excretion of Bumex amounted to only 2% of the administered dose.


Clearance

0.2 - 1.1 mL/min/kg [preterm and full-term neonates with respiratory disorders]

2.17 mL/min/kg [neonates receiving bumetanide for volume overload]

1.8 +/- 0.3 mL/min/kg [geriatric subjects]

2.9 +/- 0.2 mL/min/kg [younger subjects]


5.6 Metabolism/Metabolites

45% is secreted unchanged. Urinary and biliary metabolites are formed by oxidation of the N-butyl side chain.


5.7 Biological Half-Life

60-90 minutes


5.8 Mechanism of Action

Bumetanide interferes with renal cAMP and/or inhibits the sodium-potassium ATPase pump. Bumetanide appears to block the active reabsorption of chloride and possibly sodium in the ascending loop of Henle, altering electrolyte transfer in the proximal tubule. This results in excretion of sodium, chloride, and water and, hence, diuresis.
