Nifuratel is nitrofuran derivatives, is a broad-spectrum antibiotics, it has broad-spectrum antimicrobial effect, the fungicidin is of alkenes antifungal drugs, To trichomonad, bacteria, candida albicans have strong activity, especially for gynecology infection pathogens such as gram-positive bacterium and Gram-negative bacterium, trichomonad, mould, chlamydia and mycoplasma have strong exterminate action. After absorbing the oral gastrointestinal tract, most of the renal excretion through in the blood and urine, genital organization have high concentration, therefore, in urinary system can produce strong antibacterial action, and its metabolites still has antibacterial activity, and eject as urine. |
