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.

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.
