Contra-indicationsDo not use in acute glomerular nephritis, in electrolyte diseases, in patients with anuria, or patients that have received excessive doses of cardiac glycosides. Because of the danger of potentiating their toxic effects do not use with aminoglycoside or cephalosporin antibiotics. Allergic reactions have been associated with use with sulphonamides.
Special WarningsThe patient may increase its water intake to compensate for the diuresis. Consideration should be given to restricting water intake if the patient's condition makes such a course appropriate.
Special PrecautionsSpecial precautions for use in animals:Prolonged dosage may on occasions justify potassium supplementation and thus monitoring for hypokalaemia should be considered, especially if the product is used in conjunction with cardiac glycosides.Special precautions to be taken by the person administering the medicinal product to animals:Wear gloves or wash hands immediately after handling tablets. In case of accidental ingestion seek medical attention and show product label and/or pack insert to the doctor.
Adverse ReactionsNone reported
Pregnancy and LactationThe safety of use in pregnancy is not well established and a careful assessment of the likely benefits and potential risks should be made. A deleterious effect on lactation is to be expected, particularly if drinking water is restricted. Furosemide passes into milk, but not to a great extent.
InteractionsPotential interactions with other drugs include ototoxicity with aminoglycosides and nephrotoxicity with cephalosporins. Use in combination with sulphonamide treatment may lead to sulphonamide allergy. There is a possibility of interaction with cardiac glycosides.
Amounts to be Administered and Administration Route5mg/KgBW, one or two times per day. For patients weighing less than 8Kg dosage with the 20mg tablet (which may be halved) is recommended. Avoid overdosage in weak and old patients.
OverdoseDehydration and electrolyte depletion may occur. Monitor and correct, as necessary. Dosage higher than that which is recommended, may cause transitory deafness. Cardiovascular side effects may be observed in weak and old patients following overdose.

Furosemide is a loop diuretic produced by the kidneys which works by increasing urine output. It helps remove excess fluids from the body which helps treat conditions such as hypertension, congestive heart failure and angina.
Furosemide is a potent “loop” drug which has a high affinity binding sites for the following FDA-approved indications:
This is an example of using very sensitive analytical methods for the determination of loop diuretics like furosemide. Furosemide is a loop diuretic which works by removing excess fluids from the body which helps treat conditions such as hypertension, congestive heart failure and angina. It also helps relieve symptoms of heart failure and angina.
The furosemide binding site for loop diuretics is approximately 3.5Å compared to 1.25Å for furosemide. Furosemide affinity binding for the loop of Henle is 30% which means that approximately 80% of the binding site for loop diuretics for heart failure and 90% for hypertension binding for angina will be for the loop of Henle which is approximately 1% and 40% respectively. Anginal symptoms can be reduced with increased urine output to relieve anginal symptoms.
The furosemide binding sites are approximately 3.5Å for the loop diuretics and approximately 1.25Å for the sodium channel blocker. The binding site for furosemide is approximately 2.5Å which means that approximately 60% of the binding site for furosemide is for the sodium channel blocker which is approximately 2%.
