🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine is a nitrofuran antibacterial that enters bacterial cells through passive diffusion and is activated by bacterial flavoproteins to form reactive intermediates. These intermediates damage bacterial ribosomal RNA, DNA, and other macromolecules, leading to inhibition of protein synthesis and cell death. It is bactericidal against many urinary pathogens and has a low likelihood of inducing resistance because it acts at multiple sites.
