Furosemide Chemical Properties,Usage,Production
Efficient diuretics
Furosemide, is a class of efficient sulfonamide diuretics acting on the medullary loop of the ascending branch of the medulla,it has a strong and short-term diuretic effect,which can increase the excretion of water, sodium, chloride, potassium, calcium, magnesium, phosphate and so on. It Mainly inhibits Na + and Cl-reabsorption in medullary and cortex of the medullary loop ascending branch crude segment , it can promote the excretion of sodium, chloride and potassium and affect the formation of renal medullary high osmotic pressure,it can interfer the process of concentration and dilution of urine, and it can increase urine output. This product can inhibit the activity of prostaglandin decomposition enzyme ,make the content of prostaglandin E2 increase,it has effect on expansion of blood vessels, it also plays a role in the proximal tubule, glomerular filtration,it can increase renal blood flow,and adjust renal blood flow distribution,and reduce blood flow so that the cortex surface blood flow increases,it promotes diuresis, its effect is fast and strong, it is used for other diuretics invalid cases. Clinically it is used for the treatment of cardiac edema, renal edema, cirrhosis ascitic fluid, peripheral edema caused by dysfunction or vascular disorders , and it may contribute to an upper urinary tract stones excretion. Administration intravenously can treat brain edema, it also can accelerate the excretion of toxic substances in cerebral edema in poisoning . Note that when the diuretic furosemide is used, since the excretion of urine Cl-, Na +, K +, H + is increasing, while the excretion of HCO3-is not increasing, long-term repeated drug use or large quantities of drugs can cause low salt syndrome, low chlorine and low potassium alkalosis.
In recent years, researchers find that inhalation of furosemide can have a significant effect on asthma, it is like cromolyn sodium, which through inhibition of allergic mediator release, it can inhibit the release of the neurotransmitter acetylcholine and substance P, which may be related to inhibiting chloride ions into the cell membranes of respiratory tract. Clinically,it is used in exercise-induced asthma, immediate and delayed type antigen-induced asthma.

Description
Furosemide (Item No. 26298) is an analytical reference standard categorized as a diuretic. Formulations containing diuretics, including furosemide, have been misused in sports for weight reduction and as masking agents in humans and to prevent exercise-induced pulmonary hemorrhage in racehorses. This product is intended for use in analytical forensic applications. This product is also available as a general research tool .
Chemical Properties
white to light yellow crystal powde
Originator
Lasix,Hoechst,W. Germany,1964
Uses
diuretic, antihypertensive
Uses
Furosemide inhibits ion co-transport in the kidney. Furosemide is used as a diuretic.
Uses
This compound belongs to the aminobenzenesulfonamides. These are organic compounds containing a benzenesulfonamide moiety with an amine group attached to the benzene ring.
Uses
An inhibitor of NKCC and a GABAA receptor antagonist.
Definition
A benzoic-sulfonamide-furan. It is a diuretic with fast onset and short duration and anti-hypertensive agent.
Manufacturing Process
10.8 grams of 3-sulfamyl-4,6-dichlorobenzoic acid (0.04 mol) and 11.7 grams of furfurylamine (0.12 mol) are heated in 30 cc of diethyleneglycoldimethylether for 6 hours under reflux. When pouring the reaction mixture into 300 cc of 1 N hydrochloric acid, the reaction product is immediately separated off in the form of crystals. The light-yellow crude product is purified by dissolving it in 100 cc of warm 1 N sodium bicarbonate solution, precipitation by means of hydrochloric acid and subsequent recrystallization from ethanol/water, with addition of charcoal. Colorless prisms are obtained which decompose at 206°C while adopting a brown coloration, and with evolution of gas.
brand name
Lasix (Sanofi Aventis).
Therapeutic Function
Diuretic
General Description
Odorless white to slightly yellow crystalline powder. A diuretic drug. Almost tasteless.
Air & Water Reactions
Light sensitive. Air sensitive. Slightly soluble in water.
Reactivity Profile
Furosemide may undergo hydrolysis at sufficiently low pH. The pH of aqueous solutions should be maintained in the basic range to prevent hydrolysis. Alcohol has been shown to improve the stability of Furosemide. Incompatible with strong oxidizing agents .
Hazard
Poison; moderately toxic; teratogen; questionable carcinogen; mutagen.
Fire Hazard
Flash point data for Furosemide are not available; however, Furosemide is probably combustible.
Biological Activity
Loop diuretic that inhibits the Na + /2Cl - /K + (NKCC) cotransporter. Also acts as a non-competitive antagonist at GABA A receptors with ~ 100-fold greater selectivity for α 6-containing receptors than α 1-containing receptors.
Biochem/physiol Actions
Inhibits ion co-transport in the kidney.
Mechanism of action
Furosemide is a highly effective and quick-acting diuretic whose action, like all of the examined loop diuretics, is associated with blocking reabsorption of ions in the ascending bend of Henle’s loop. It is used for edema syndrome of various origins, edema of the lungs and brain, chronic renal insufficiency, some forms of hypertonic crises, and poisoning by barbiturates and other compounds excreted mainly with urine.
Clinical Use
Furosemide has a saluretic effect 8- to 10-fold that of the thiazide diuretics; however, it has a shorter duration of action (~6–8 hours). Furosemide causes a marked excretion of sodium, chloride, potassium, calcium, magnesium, and bicarbonate ions, with as much as 25% of the filtered load of sodium excreted in response to initial treatment. It is effective for the treatment of edemas connected with cardiac, hepatic, and renal sites. Because it lowers the blood pressure similar to the thiazide derivatives, one of its uses is in the treatment of hypertension.
Side effects
Clinical toxicity of furosemide and other loop diuretics primarily involves abnormalities of fluid and electrolyte balance. As with the thiazide diuretics, hypokalemia is an important adverse effect that can be prevented or treated with potassium supplements or coadministration of potassium-sparing diuretics. Increased calcium ion excretion can be a problem for postmenopausal osteopenic women, and furosemide generally should not be used in these individuals. Hyperuricemia, glucose intolerance, increased serum lipid levels, ototoxicity, and gastrointestinal side effects might be observed as well. Hypersensitivity reactions also are possible with furosemide (a sulfonamide-based drug), and cross-reactivity with other sulfonamide containing drugs is possible.
Safety Profile
Poison by intravenous route. Moderately toxic by ingestion and intraperitoneal routes. Human systemic effects by intravenous route: change in the sensitivity of the ear to sound, tinnitus, unspecified effects on the heart, constriction of the arteries, a decrease in urine volume, interstitial nephritis, metabolic alkalosis, pulse rate decrease, fall in blood pressure. Ingestion can damage the liver. Experimental teratogenic and reproductive effects. Questionable carcinogen with experimental carcinogenic effects. Human mutation data reported. When heated to decomposition it emits very toxic fumes of Cl-, NOx, and SOx.
Synthesis
Furosemide, 4-chloro-N-furfuryl-5-sulfamoylanthranylic acid (21.4.11), is synthesized in a relatively simple manner from 2,4-dichlorobenzoic acid, which is converted into 5-aminosulfonyl-4,6-dichlorobenzoic acid (21.4.10) during subsequent reaction with chlorosulfonic acid and ammonia. Reacting this with furfurylamine gives furosemide (21.4.11) .
Veterinary Drugs and Treatments
Furosemide is used for its diuretic activity in all species. It is used in small animals for the treatment of congestive cardiomyopathy, pulmonary edema, hypercalcuric nephropathy, uremia, as adjunctive therapy in hyperkalemia and, occasionally, as an antihypertensive agent. In cattle, it is approved for use for the treatment of post-parturient udder edema. It has been used to help prevent or reduce epistaxis (exercise-induced pulmonary hemorrhage; EIPH) in racehorses.
