1. What is Diuver and what is it used for

Diuver is a diuretic medicine. After oral administration, torasemide is quickly and almost completely absorbed, and the maximum concentration occurs in the serum after 1 to 2 hours. About 80% of the administered dose is excreted in the urine.
Indications for use:

• primary hypertension;
• edema caused by congestive heart failure, pulmonary edema, hepatic edema, and renal edema.

2. Important information before taking Diuver

When not to take Diuver

• if the patient is hypersensitive to torasemide, sulfonylurea derivatives (diabetes medications) or any of the other ingredients of this medicine (listed in section 6);
• if the patient has renal dysfunction with anuria;
• if the patient has hepatic coma and pre-coma states;
• if the patient has arterial hypotension;
• if the patient is breastfeeding.

Warnings and precautions

Before starting treatment with Diuver, the patient should discuss it with their doctor or pharmacist.

• if the patient has urinary disorders, before starting treatment, the cause of these disorders should be eliminated and water and electrolyte balance should be restored (especially in patients undergoing concomitant treatment with digitalis glycosides, glucocorticoids, mineralocorticoids, or laxatives).
• if torasemide therapy is long-term. During long-term treatment, regular monitoring of water and electrolyte balance, glucose, uric acid, creatinine, and lipid levels in the blood, as well as blood morphology (red and white blood cells and platelets), is recommended.
• if the patient has a tendency to increased uric acid levels in the blood and gout.
• if the patient has latent or overt diabetes. In these patients, carbohydrate metabolism should be monitored.

Due to insufficient experience with torasemide treatment, caution should be exercised in the following situations:

• pathological changes in acid balance,
• concomitant treatment with lithium, aminoglycosides, or cephalosporins,
• renal failure caused by nephrotoxic factors,
• children under 12 years of age.

Taking Diuver may lead to positive doping control results. Using Diuver as a doping agent can pose a health risk.

Children and adolescents

There is a lack of clinical experience with the use of torasemide in this age group.

Diuver and other medicines

The patient should tell their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take.
In the case of concomitant use of torasemide with cardiac glycosides (medicines that stimulate heart function, increase the force of myocardial contraction, and at the same time decrease the frequency of this contraction), there may be an increased sensitivity of the myocardium to these medicines due to decreased potassium and (or) magnesium levels in the serum.
In combination with mineralocorticoids (hormones that regulate mineral and ion metabolism in the body) and glucocorticoids (hormones that regulate protein, carbohydrate, and fat metabolism) and laxatives, it may cause increased potassium excretion in the urine.
Similarly, as with other diuretic medicines, the hypotensive effect may be enhanced during concomitant administration of other antihypertensive medicines.
Torasemide, especially in high doses, may increase the toxicity of aminoglycoside antibiotics, cisplatin, the nephrotoxic effect of cephalosporins, and the toxic effect of lithium on the heart and central nervous system.
The effect of curare-like muscle relaxants and theophylline may be enhanced during concomitant use with torasemide.
Since torasemide inhibits the renal excretion of salicylates in patients receiving high doses of salicylates, their toxicity may increase.
The effect of antidiabetic medicines may be weakened.
The use of angiotensin-converting enzyme inhibitors after torasemide treatment, or the initiation of combined therapy with these medicines, may cause transient blood pressure drops. This effect can be minimized by reducing the initial dose of the angiotensin-converting enzyme inhibitor and (or) reducing the dose or temporarily discontinuing torasemide for 2-3 days before using the medicine from the group of angiotensin-converting enzyme inhibitors.
Torasemide may reduce the reactivity of arteries to vasoconstrictor medicines (e.g., adrenaline, noradrenaline).
Nonsteroidal anti-inflammatory medicines (e.g., indomethacin) may reduce the diuretic and hypotensive effects of torasemide by inhibiting prostaglandin synthesis.
Probenecid may reduce the effectiveness of torasemide by inhibiting its secretion in the renal tubules.
The concomitant administration of torasemide and cholestyramine has not been studied in humans, but in animal studies, a decrease in torasemide absorption has been observed.

Diuver with food and drink

Diuver should be taken in the morning with a small amount of liquid, regardless of meals.

Patients with liver function disorders

During torasemide treatment, patients with liver function disorders should be under special supervision due to the risk of increased torasemide levels in the blood.

Patients of advanced age

In elderly patients, there is no need to adjust the dosage.

Pregnancy and breastfeeding

If the patient is pregnant or breastfeeding, thinks she may be pregnant, or plans to have a child, she should consult her doctor or pharmacist before taking this medicine.
Pregnancy:
Diuver is contraindicated during pregnancy.
Breastfeeding:
There is no data on the penetration of the medicine into breast milk. Diuver is contraindicated during breastfeeding.
Fertility:
In non-clinical studies, no effect of torasemide on fertility was found.

Driving and operating machines

As with other medicines that affect blood pressure, patients who take torasemide and experience dizziness or similar symptoms should not drive vehicles or operate machines.

Diuver contains lactose monohydrate.

If the patient has previously been diagnosed with intolerance to some sugars, the patient should contact their doctor before taking the medicine.

Diuver contains sodium.

The medicine contains less than 1 mmol (23 mg) of sodium per dose, which means the medicine is considered "sodium-free".

3. How to take Diuver

This medicine should always be taken as directed by the doctor. In case of doubts, the patient should consult their doctor or pharmacist.
Recommended dose
Adults:

Primary hypertension

A dose of 2.5 mg orally once a day is recommended. If necessary, the dose can be increased to 5 mg once a day. Studies suggest that doses greater than 5 mg per day do not lead to further blood pressure reduction. The maximum therapeutic effect is achieved after approximately 12 weeks of treatment.

Edema

Usually, a dose of 5 mg orally once a day is used. If necessary, the dose can be gradually increased to 20 mg once a day. In individual, exceptional cases, doses of up to 40 mg per day have been used.

Taking a higher dose of Diuver than recommended

The typical picture of torasemide overdose is not known. In case of overdose, significant diuresis may occur with a risk of fluid and electrolyte loss, and subsequently drowsiness, confusion, blood pressure drop, and circulatory collapse. Gastrointestinal disorders may occur.
There is no specific antidote. The symptoms of overdose require a reduction in dose or discontinuation of the medicine, along with the administration of fluids and electrolytes.
In case of taking a higher dose of the medicine than recommended, the patient should immediately consult their doctor or pharmacist.

Missing a dose of Diuver

A missed dose should be taken as soon as possible. If it is almost time for the next dose, the patient should take it at the scheduled time.
A double dose should not be taken to make up for a missed dose.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.
Common(may affect up to 1 in 10 people):
Similarly to other diuretic medicines, depending on the dose and duration of treatment, water and electrolyte disorders may occur, especially when using a low-sodium diet. Hypokalemia (decreased potassium levels in the blood) may occur, especially in patients on a potassium-poor diet, with vomiting, diarrhea, using large amounts of laxatives, and in cases of liver dysfunction.
In case of significant diuresis, especially at the beginning of treatment, and in elderly patients, symptoms of electrolyte and fluid loss may occur, such as headache and dizziness, blood pressure drop, weakness, drowsiness, confusion, loss of appetite, and muscle cramps. A dose adjustment may be necessary.
Torasemide may cause increased uric acid, glucose, and lipid levels in the serum.
Metabolic alkalosis symptoms may worsen.
Gastrointestinal disorders (e.g., loss of appetite, abdominal pain, nausea, vomiting, diarrhea, constipation) may occur.
Torasemide may cause increased activity of certain liver enzymes, e.g., gammaGT (gamma-glutamyltransferase).
Uncommon(may affect up to 1 in 100 people):
In patients with urinary disorders, sudden cessation of urine production may occur. Increased levels of urea and creatinine in the blood may occur.
Rare(may affect up to 1 in 1,000 people):
Paresthesia of the limbs
Very rare(may affect less than 1 in 10,000 people, including single cases):
Thrombotic complications and circulatory disorders of the heart and brain, caused by blood thickening (including myocardial infarction and cerebral infarction), leading to arrhythmias, angina pectoris, acute myocardial infarction, or fainting.
