Mechanism
of Action

⚙️ Mechanism of Action of Nitrotoin (Nitrofurantoin 100mg)

Nitrotoin (Nitrofurantoin 100mg) works through a unique multi-targeted antibacterial action, making it especially effective in the urinary tract.

 

🔬 How It Works:

  1. Bacterial Enzyme Activation:
    Once Nitrotoin (Nitrofurantoin 100mg) enters bacterial cells, it is reduced (activated) by bacterial enzymes called nitrofuran reductases.
  2. Formation of Reactive Compounds:
    This activation leads to the production of highly reactive intermediates that damage:
    • Bacterial DNA
    • Ribosomal proteins
    • Cell wall and metabolic enzymes
  3. Disruption of Vital Functions:
    The cumulative damage to these essential components kills or stops the growth of bacteria (bactericidal or bacteriostatic effect depending on concentration).

🎯 Site-Specific Action:

  • It is concentrated in urine, making it highly effective against bacteria in the urinary tract with minimal systemic exposure.

🧪 Summary:

Nitrotoin (Nitrofurantoin 100mg) is reduced inside bacterial cells → produces reactive intermediates → damages DNA, proteins, and cell walls → inhibits growth and causes bacterial death.
