Solution for injection. A clear, yellowish fluid.

Cattle, horses, cats and dogs.

A potent saluretic type of diuretic for parenteral administration to cattle, horses, cats and dogs. Dimazon is indicated in the treatment of oedemata associated with cardiac insufficiency, renal dysfunction, trauma and parasitic disease. It is also recommended for the treatment of mammary oedema and limb oedemata.

The product gives rapid onset of diuretic action with increased sodium and water excretion. It is even effective where glomerular filtration is impaired.

Do not use in cases of acute glomerular nephritis renal failure with anuria, electrolyte deficiency disease or overdosage with digitalis.

Do not use concurrently with aminoglycoside antibiotic treatment.

The therapeutic effect may be impaired by increased intake of drinking water. So far as the patient's condition allows, the amount of drinking water should be restricted.

Do not use in cases of hypersensitivity to the active substance or to any of the excipients.

Clinical experience with dogs indicates that improved results can frequently be achieved by supplementary administration of corticosteroids

In pulmonary oedema of cardiac origin, combined therapy with cardiac glycosides is advisable. Only during prolonged treatment is it necessary to monitor potassium balance. Potassium supplements may be necessary.

Care should be taken to avoid accidental self-injection. If irritation occurs, seek medical attention, showing the product label to a doctor. Following skin/eye contamination, wash/irrigate area with clean, running water immediately. Wash hands after use.

Too rapid injection in dogs may cause staggering and vomiting.

Can be used during pregnancy and lactation.

Potential interactions with other drugs include ototoxicity with aminoglycosides and nephrotoxicity with cephalosporins.

Use in combination with sulphonamide treatment may lead to sulphonamide allergy.

In severe or refractory cases, the dose may be doubled on a single occasion in the horse or cow.

The product may be administered observing aseptic precautions:

- by intravenous injection only in cattle and horses.

- by intramuscular or intravenous injection only in cats and dogs.

Doses higher than recommended may cause transitory deafness.

Cardiovascular side effects may be observed in weak and old patients following overdosage.

Meat and offal: 28 days.

Milk: 24 hours.

Not to be used in horses intended for human consumption.

Treated horses may never be slaughtered for human consumption.

The horse must have been declared as not intended for human consumption under national horse passport legislation.

ATCvet code: QC03CA01

Cardiovascular system, high-ceiling diuretics, sulfonamides, plain; furosemide.

Furosemide is a derivative of sulphamoyl-anthranilic acid and is a rapid onset diuretic used in animals and humans. Furosemide acts on the urine producing regions of the nephron and increases the filtration volume while impairing the re-absorption of sodium, chlorine and water. An isotonic or slightly hypotonic urine with unchanged or slightly acid Ph is produced. Potassium excretion is only significantly increased after large doses.

The absorption of furosemide is rapid but incomplete with maximum plasma levels occurring within 1 hour of dosing depending on the administration route. Furosemide is not accumulated after repeated dosing as evidenced by comparison of plasma profiles and of tissues concentrations.

The volume of distribution is relatively low, indicating limited distribution into tissues (mainly liver and kidney), also reflecting the extensive plasma protein binding. Absorption and tissue distribution are extremely fast in cattle after i.m. administration. In plasma, maximum levels range from 15 minutes to 1.5 hour, and the half-life is 0.22-2.7 hours. Elimination is predominantly renal via urine, and is clearly prolonged after oral and i.m. administration compared to i.v. administration (probably because delayed absorption). Lesser quantities are eliminated via faeces and very little via milk (half-life 3 hours). Only small quantities are excreted in the bile. The majority of the total dose is excreted within 24 hours.

The apparent volume of distribution is 0.66 L/kg in horses. The elimination half-life is prolonged after i.m. administration compared with i.v. administration (65-86 vs 25-39 minutes, respectively), probably on account of delayed absorption. The half-life of 7.6 hours from the urine points to a distribution to poorly perfused tissues. The total clearance is about 12 mL/kg/min and the renal excretion accounts for 60% in unmetabolised form. Plasma protein binding of furosemide in horses in about 95%. Up to 60% of the amount of furosemide injected i.v. is rapidly excreted unchanged in the urine, and furosemide is still detectable in urine for about 12 hours.

Following parenteral administration, furosemide is rapidly absorbed with maximum plasma levels occurring within 10-15 minutes. It is not accumulated after repeated dosing. Plasma half-lives are similar across species after i.v. administration (dog 12-24 minutes). Elimination is rapid and predominantly via the kidneys in the urine. The majority of the total dose is excreted within the first 24 hours (after i.v. injection in dogs, about 44-56% of the dose are excreted in the urine within one hour and 55-69% within 24 hours). The faeces contain 17-39% of the dose. Plasma protein binding of furosemide is 91% and estimated distribution volume is 0,52 L/kg. Furosemide metabolizes in very small amounts (main metabolite: 4-chloro-5-sulfamoyl-anthranilic-acid, no diuretic activity).
