Furadonin

Furadonin is a drug from the group of nitrofurans, which breaks the permeability of the cell membrane and protein synthesis in bacteria, having a bactericidal, bacteriostatic effect.

This drug is effective for the treatment of diseases of the genitourinary system, as it accumulates in large concentrations in the urine and is excreted by the kidneys. Well tolerated for short-term use. The therapeutic effect develops fairly quickly and persists for a long time. It is shown in the development of infectious disease of the prostate in men and symptomatic treatment of STI.

The drug is well absorbed from the gastrointestinal tract, penetrates the placenta and into breast milk, cerebrospinal fluid, and is excreted by the kidneys. Can give urine a dark color. Concentration in blood at usual therapeutic doses is insignificant.

Pharmacological effect

Furadonin is a broad-acting antimicrobial agent derived from nitrofuran, but is not part of the antibiotic group. Due to the active substance, the drug has bactericidal and bacteriostatic effects in infections of the urinary tract. The medicine destroys the membranes of bacteria, inhibits the synthesis of proteins, destroys the E. coli, Klebsiella, enterobacteria, protea, staphylococcus. The agent is well absorbed by the digestive tract, its bioavailability increases with the ingestion of food.

According to these instructions, the rate of absorption of antibacterial agent depends on the size of the crystals (the powder dissolves more rapidly, absorbed, and concentrates as quickly as possible in the urine). The substance binds to plasma proteins by 60%, is metabolized by the liver and muscle tissues, the half-life is 20-25 minutes. Nitrofurantoin penetrates the placental and blood-brain barrier, is excreted by the kidneys.

Indications for use

Furadonin is used to treat and prevent infectious-inflammatory diseases of the urinary tract (caused by drug-susceptible pathogens):

• pyelitis;
• pyelocystitis;

Intended use for pregnancy and lactation

Given the fact that Furadonin penetrates the placenta and can have toxic effects on the fetus, it is contraindicated to take it during pregnancy.

Experimental studies in animals have revealed a risk to the fetus. The clinical experience of using Furadonin during pregnancy has not been studied.

Doctors-gynecologists sometimes use Furadonin in the treatment of urinary tract infections in women after 12 weeks of pregnancy. In this case, it is necessary to compare the possible risk to the fetus and the therapeutic effect of using Furadonin.

Dosage and route of administration

As indicated in the instructions for use, Furadonin tablets are intended for oral administration as an independent bacteriostatic agent or as part of complex therapy for the treatment of urinary tract diseases caused by microorganisms sensitive to nitrofurans. The dose of the drug and the duration of the course of treatment is determined by the doctor strictly individually for each patient.

According to the instructions, adult patients and children over 12 years of age are prescribed 50-100 mg of the drug 4 times a day. For children younger than 12 years, a single dose of the drug is calculated based on the weight - 5 mg / kg body weight. The duration of the course of therapy with the drug is 3-5 days, if necessary, treatment can be extended up to 14 days under the supervision of a doctor.

Compatibility with other drugs

Nitrofurantoin is not compatible with fluoroquinolones.

The simultaneous use of nalidixic acid and antacids containing magnesium trisilicate reduces the antibacterial effect of nitrofurantoin.

With simultaneous use of drugs that block tubular secretion, reduce the antibacterial effect of nitrofurantoin (by reducing the concentration of nitrofurantoin in urine) and increase its toxicity (blood concentration increases).

Reviews

With the acute manifestation of cystitis, I immediately took 2 pills of furadonin, after 15-20 minutes, a terrible sensation of nausea started, and strong weakness, plus it cuts below the abdomen. I already thought that I would not survive until the morning. Whom you ask, everyone says that it causes vomiting and nausea.
3. Galina. Furadonin removes only the symptoms of cystitis, and the disease as it is remains. You can take if you just catch a cold, And if it's gone far, then an excellent drug is Kanefron.
